1. The importance of using Wi-Fi when traveling abroad

1.1 The necessity and convenience of Wi-Fi

When traveling abroad, an internet connection is essential for gathering information and communicating with others at your destination. For travelers, navigating with map apps, checking reviews of restaurants and tourist spots, and sharing information on social media have become part of daily life. With Wi-Fi, you can take advantage of these features without having to worry about international roaming or expensive data charges.

The Internet is also useful for emergency contact and for dealing with unexpected problems. For example, the availability of Wi-Fi makes a big difference in situations where you need to obtain timely information, such as flight delay information or changes to hotel reservations.

Having Wi-Fi helps you minimize inconvenience while traveling abroad and allows you to enjoy a comfortable trip.

1.2 Options for connecting to the Internet overseas

There are several options for connecting to the Internet while traveling abroad. Each method has its own advantages and disadvantages, so it is important to choose the best method depending on the purpose of your trip and your usage.

1. Roaming Service
   International roaming provided by mobile carriers is one of the most convenient options. It is especially useful when you are traveling for a short time or want to keep your regular phone number. However, roaming data can be expensive, and depending on how you use it, it can cost more than you expected.
2. Purchasing a local SIM card
   You could also buy a local SIM card and put it in your smartphone. This is cost-effective, especially if you're staying for an extended period of time. However, it can be a hassle, as you'll often need the local language and settings, and you'll need an unlocked device.
3. Free Wi-Fi available
   Free Wi-Fi is available in many public facilities, such as cafes, hotels, and airports. The fact that it's free is appealing, but security issues and unstable connection speeds are drawbacks. Also, the areas where it can be used are limited, so it's not suitable for people who need a constant connection.
4. Overseas Wi-Fi Rental
   Renting a Wi-Fi router overseas is a good option, especially for group trips or when using multiple devices. You can choose unlimited or large capacity plans for a fixed fee, and enjoy stable connections. Another convenient feature is that you can rent in Japan in advance and pick it up before you leave.

When choosing an internet connection option overseas, it's important to choose one based on your travel style and data usage.

1.3 How to choose overseas Wi-Fi

When choosing overseas Wi-Fi, it is important to keep the following points in mind. Each plan and service has different features, so choosing the Wi-Fi that best suits your needs as a traveler will ensure a comfortable internet connection.

1. Areas covered by your destination
   First, you need to check whether Wi-Fi is available in the country or region you are traveling to. The countries and regions supported vary depending on the Wi-Fi router provided, so be sure to check the area where the service is available. Global Wi-Fi that covers a wide area is especially convenient if you are visiting multiple countries.
2. Communication capacity
   Data capacity varies greatly depending on how much you use the internet. If you plan to watch videos while traveling or frequently upload photos to social media, it is best to choose a large capacity or unlimited plan. On the other hand, if you mainly check email and use map apps, a smaller capacity may be sufficient. Choosing the capacity that suits your needs is the key to optimizing cost performance.
3. Speed ​​and Stability
   The speed and stability of your internet connection are also important selection criteria. In particular, you need a fast and stable connection when making video calls or watching videos. Some plans have speed limits after a certain amount of data is used, so be sure to check before signing up.
4. Pricing Plans
   Prices vary greatly depending on the service and plan. Choose the best plan based on the number of days you will be traveling and the amount of data you will need. If you are staying for a long period of time, you can reduce costs by choosing a rental company that offers discount plans based on the number of days or a flat rate.
5. How to pick up and return
   Another important point is whether you can pick up and return the Wi-Fi router smoothly. If you choose a company that allows you to pick it up at the airport or at your home before you leave, it will be convenient so that you can use it as soon as you arrive at your destination. Also, if you check whether it is easy to return it after you return home, you can save yourself the trouble of doing so after your trip.

Taking all these factors into consideration and choosing the overseas Wi-Fi that's right for you is the key to having a comfortable trip.

2. Tips for choosing Wi-Fi capacity when traveling abroad

2.1 Factors that determine capacity (purpose, number of people, length of stay)

There are three main factors to consider when deciding on the amount of data you need for overseas Wi-Fi: your purpose , the number of people traveling , and the number of days you will be staying . By taking these factors into consideration, you can choose the most suitable plan without wasting money.

1. Purpose of Use
   The most important factor is how you use the internet while traveling. For example, if you only use it lightly, such as checking map apps, emails, and sending and receiving text messages, 300MB to 500MB per day will be sufficient. On the other hand, if you frequently post photos and videos to social media and watch streaming videos on YouTube, it is safer to consider a plan of 1GB or more.
2. Number of travelers
   The number of people sharing the Wi-Fi router is also an important point to consider when choosing communication capacity. The amount of data used per person will differ depending on whether you are using it alone or sharing with family or friends. If you are sharing with 2 to 3 people, we recommend a plan with 1GB or more per day, or an unlimited plan.
3. Length of stay
   The longer you stay, the more opportunities you will have to use the internet. For long-term stays or frequent business use, an unlimited plan is likely to be the most stress-free option. For short trips, limited daily usage may not be an issue. For example, a 1GB daily plan may be more than enough for a 5-day trip.

Data capacity is an important factor that determines whether you will have a comfortable internet environment while traveling. It is important to choose a data plan that takes into consideration the purpose, number of people, and length of stay.

2.2 Usage examples for capacity from 300MB to 1GB

When choosing a Wi-Fi plan, it is important to know how much data you need. Here, we will introduce how you can use the plans based on your daily usage, with plans ranging from 300MB to 1GB.

1. 300MB Plan
   300MB is mainly for light users . This capacity is sufficient for browsing the web, checking emails, and sending text messages on LINE. For example, you can use map apps about 50 to 80 times, and post text and light images on SNS. However, you will be limited in the use of apps that consume a lot of data, such as watching videos and making video calls .
2. 500MB Plan
   500MB is suitable for users who want to use the Internet somewhat actively. For example, you can watch about 30 minutes of YouTube videos in standard quality (480p), and there is plenty of room for map apps and posting photos on social media. If you are traveling and just want to research tourist spots and post them on social media, 500MB per day will be enough.
3. 1GB Plan
   1GB is ideal for users who frequently watch videos and post videos on social media. You can watch YouTube videos in standard resolution for over an hour , and post photos and videos to Instagram and Facebook without any problems. It also has enough capacity for video calling. If you want to use a map app to visit tourist spots and post real-time information on social media, about 1GB per day is the guideline.

The choice of capacity varies greatly depending on the apps and services you use . It is important to choose the right plan for your internet usage style.

2.3 Advantages and disadvantages of unlimited storage plans

Unlimited data plans are a very attractive option for those who want to use the Internet without worrying about data capacity. However, this convenience comes with both advantages and disadvantages. Here we will explain in detail the advantages and points to note about unlimited data plans.

merit

1. You can use it without worrying about data capacity
   The biggest advantage of an unlimited data plan is that you don't have to worry about data usage . This allows you to freely engage in activities that require a lot of data, such as watching videos for long periods of time, playing online games, making video calls, and posting frequently to social media. It is especially ideal for those who want to use the Internet without stress while traveling.
2. Ideal for multiple people
   Unlimited plans are ideal for group or family trips . Even if multiple people share one router, you can use the Internet anywhere during your trip without worrying about exceeding the capacity. This allows everyone in your group to stay connected comfortably, avoiding issues with sharing data capacity.
3. Peace of mind for long-term stays
   An unlimited plan is a great help, especially if you are staying abroad for an extended period of time for business or study abroad. Even in situations where you use the Internet a lot on a daily basis, you can always enjoy a stable Internet connection, so your work or studies will not be affected.

Disadvantages

1. Expensive
   Unlimited plans tend to be expensive . Compared to other data-limited plans, the daily rental fee is expensive and may not be cost-effective, especially for short trips. If you don't use a lot of data, a low-volume plan is more economical.
2. There may be restrictions on the country or region where you can use it.
   Some unlimited plans may only be available in certain areas . For example, unlimited plans may not be available in certain countries, or connection speeds may be slow in certain areas. It's important to check the availability of unlimited plans in your destination before you travel.

Unlimited plans are a good choice for data-intensive travelers or group trips, but it's important to consider factors like price and speed limits when choosing one.

3. Recommended plans by capacity

3.1 For light users (300MB to 500MB)

The 300MB to 500MB plans are for light users who use the internet sparingly . They are mainly suitable for people who want to use the internet a little while traveling. Below are some examples of typical activities that can be done with this capacity.

1. Checking emails and messages
   If you are only sending and receiving text-based messages and checking emails, 300MB is enough capacity for one day. For example, if you are only sending LINE messages and checking emails, you are unlikely to use up the capacity even if you use it for several days.
2. Using a map app
   The most important thing you need while traveling is to use a map app. With a 300MB to 500MB plan, you can open the map app many times a day and check your route. This is especially sufficient for short trips around the city.
3. Easy use of SNS
   Even with this capacity, you can still use social media, mainly posting text and light images. It's fine if you just post photos on Instagram or Twitter, or make short updates on Facebook. However, there are restrictions on posting and watching videos, so if you want to use videos frequently, you'll need to consider a larger capacity.

For light users, the 300MB to 500MB plan is ideal as it covers all the necessary functions while keeping costs down. With this capacity, you can connect to the Internet when you need it and use it without waste.

3.2 For video and SNS users (600MB to 1GB)

Plans between 600MB and 1GB are ideal for users who use the Internet relatively frequently, especially those who watch videos and use social media frequently . With this capacity range, you can comfortably carry out activities that require a lot of data, such as posting photos and short videos and watching YouTube.

1. Posting photos and videos to SNS
   If you frequently post photos and update stories on social media sites such as Instagram and Facebook, 600MB to 1GB of storage will be more than enough. Even if you post short videos, it will be fine if you post them a few times. This amount of storage will also give you peace of mind when viewing other users' content.
2. Watching YouTube and streaming videos
   You can watch standard quality (480p) YouTube videos for about an hour to an hour and a half . This capacity is sufficient if you want to check local information while traveling or enjoy videos as entertainment. If you want to watch videos in higher quality (720p or 1080p), you will need a larger amount of data, so a plan of around 1GB is ideal.
3. Video calls and online meetings
   If you want to make video calls with family and friends while traveling, 600MB to 1GB of storage is sufficient. For example, you can make video calls for about an hour using Skype or Zoom, with few interruptions during the call and comfortable use.

If you use a lot of video and social media, the 600MB to 1GB plan is a good choice that strikes a good balance between cost and usability. This capacity range is safe for people who frequently post photos and videos or have many opportunities to watch videos.

3.3 For large groups and long-term trips (unlimited plan)

The unlimited plan is the best choice for long-term travel or for multiple people. You can connect to the Internet at any time without worrying about data capacity, so you can use it with peace of mind in a variety of situations. This plan is especially useful when watching videos or sharing with a large group of people.

1. Use for large groups
   Unlimited plans are very convenient when sharing a Wi-Fi router with multiple people on a family or group trip . For example, many routers allow up to five people to connect at the same time, so even if everyone uses social media or map apps, there is no need to worry about exceeding the capacity. Each person can use the Internet independently during the trip, creating a stress-free environment.
2. Convenience for long-term stays
   During long-term stays, internet usage tends to increase. For example, unlimited plans are ideal for daily data usage such as contacting family via video calls and watching videos for long periods of time. With no data restrictions and comfortable daily use, life at your destination will be smoother.
3. Unlimited access to videos and online games
   With the unlimited plan, you can enjoy activities that require a lot of data, such as watching high-definition videos and playing online games , without worrying about them. You can watch movies on YouTube or Netflix, download games, update games, and perform other large-volume communications without any problems, so you can enjoy entertainment without any stress.

Unlimited plans are the most convenient plan for users who want to enjoy the Internet freely without worrying about data usage. For those who plan to use the Internet a lot while traveling or those who want to share Wi-Fi with a large group of people, the unlimited option brings peace of mind.

4. Tips for saving space

4.1 How to take advantage of offline mode

When using the Internet while traveling, you can save data by effectively using offline mode . Below are some specific ways to use offline mode.

1. Offline use of map apps
   Map apps such as Google Maps allow you to use navigation offline by downloading maps in advance. This allows you to check routes without connecting to the Internet, which can significantly reduce data usage. In particular, when traveling abroad, data usage can be expensive, so we recommend downloading maps of the area around your destination before you leave.
2. Offline music and video playback
   Streaming services like Spotify and YouTube allow you to download content in advance and play it offline. This allows you to save data even if you want to enjoy music or videos on the go, as you can play them without using up your data. This is especially useful for long flights or train rides.
3. Use offline apps
   Many apps have an offline mode, meaning they can be used even without an internet connection. For example, offline translation apps and travel planning apps allow you to download the information you need in advance so you can check it when you're there without an internet connection.
4. Browser offline capabilities
   Some browsers have a feature that allows you to view pages offline. You can bookmark the information you need before your trip and view it offline. This allows you to check guide information and details of tourist spots when you are in the area without using data.

Utilizing offline mode can significantly reduce data usage, making it a great way to make the most of Wi-Fi while traveling abroad.

4.2 Settings to reduce unnecessary data consumption

When traveling, it's easy to consume data without realizing it. Adjusting the settings on your smartphone and apps can help prevent unnecessary data usage. Below are some specific ways to save data.

1. Stop background app refresh
   Many apps use data in the background to send updates and notifications. To prevent this, disable background data usage from the settings menu. Social media, email, and news apps in particular can use up a lot of data, so we recommend setting them to update manually when traveling.
2. Turn off automatic updates
   Automatic app updates can consume large amounts of data automatically when connected to Wi-Fi. Update apps and the OS before you leave, and turn off automatic updates while traveling. This will prevent unexpected data consumption.
3. Use Data Saver Mode
   Smartphones may have a "data saver" mode to reduce data usage. Enabling this feature limits apps from using data in the background and reduces unnecessary data consumption. This feature is especially common on Android and iOS devices.
4. Change your streaming service settings
   Streaming services like YouTube and Netflix use a lot of data when playing videos in high definition. You can significantly reduce your data usage by setting the quality of these apps to low . When traveling, you can save on data usage by watching videos in standard or low definition.
5. Pause cloud sync
   Cloud services such as iCloud and Google Photos use a lot of data when they automatically sync photos and videos. By pausing the automatic syncing of these cloud services while traveling, you can save data. It is especially recommended that you upload photos and videos in a location with a stable Wi-Fi connection.

By adjusting these settings, you can reduce unnecessary data consumption and make efficient use of your limited Wi-Fi capacity while traveling.

4.3 Using public Wi-Fi and precautions

Free Wi-Fi provided in public places while traveling is a very effective way to save data communication. Free Wi-Fi is available in various places such as airports, hotels, cafes, and tourist spots, so you can connect to the Internet while saving data. However, there are some risks and precautions to be aware of when using public Wi-Fi, so you need to know the points to use it wisely.

1. Beware of security risks
   Free Wi-Fi poses security risks because anyone can access it. In particular, open networks without passwords are at high risk of being hacked or having personal information stolen . For this reason, when using free Wi-Fi, it is important to avoid exchanging confidential information such as bank or credit card details, and to use a secure network for important transactions.
2. Using a VPN
   For added security, we recommend using a **VPN (Virtual Private Network)**. Using a VPN encrypts your internet connection and reduces the risk of third parties eavesdropping on or manipulating your communications. If you frequently use public Wi-Fi, it's a good idea to set up a VPN before you travel.
3. Choose a reliable network
   When using public Wi-Fi, it is important to choose networks provided by trusted facilities and brands. Using official Wi-Fi networks such as those found at airports, hotels, and cafes can help reduce security risks to some extent. It is important to always check the network name to make sure it is a legitimate network.
4. Turn off auto-connect
   Depending on the settings of your smartphone or tablet, it may automatically connect to public Wi-Fi that you have connected to before. By turning off this function, you can prevent the risk of connecting to unintentionally dangerous networks. Make it a habit to manually select and check the security status when connecting.
5. Choose Wi-Fi with a password
   We recommend using password -protected Wi-Fi whenever possible. Prioritize protected networks such as those provided for visitors in hotels and restaurants, where the password is often provided.

Public Wi-Fi is a convenient tool, but the key to avoiding trouble is to use it with proper security measures . Follow these precautions to use free networks safely.

5. How to choose the best Wi-Fi rental service for overseas travel

5.1 Points to consider when comparing services (price, capacity, speed)

When choosing an overseas Wi-Fi rental service, important points to compare are price , capacity , and speed . By carefully considering these factors, you can find a service that allows you to comfortably use the Internet while traveling.

1. Fee
   Price is one of the most basic factors when choosing a Wi-Fi rental service. The plans offered by each company are priced per day, and prices vary depending on capacity and speed . For example, plans for light users with small capacity are inexpensive, but plans offering unlimited capacity or high speed tend to be expensive. If you are traveling for a long period of time or use the Internet frequently, you may want to consider long-term use discounts or package plans, as the daily cost may be discounted.
2. capacity
   Data capacity is the most important factor when selecting a Wi-Fi router. Each service often sets a daily data capacity, with options such as 300MB , 500MB , 1GB , and unlimited . A small amount of capacity is sufficient for social media use and simple web searches, but if you frequently watch videos or hold online meetings, a 1GB or more or unlimited plan is recommended. Also, if multiple people will be using the router at the same time, such as on a group trip, it is advisable to choose a larger capacity.
3. Communication speed
   Communication speed is a factor that directly affects the comfort of the Internet. With Wi-Fi rental services, the speed varies depending on the type of communication line used. Generally, 4G LTE and 5G compatible routers provide high-speed communication, allowing you to use the Internet without stress. However, depending on the plan, speed restrictions may be imposed once a certain amount of communication is exceeded, so if you are particular about speed, it is best to choose an unlimited plan or a plan with a loose speed restriction.

Price, capacity, and speed are the most important factors when choosing a service. Compare these factors comprehensively based on your travel purpose and usage, and choose the plan that suits you best.

5.2 The Importance of a Support System

When choosing a Wi-Fi rental service, the support system is very important. In particular, if you encounter a problem while traveling abroad, whether or not you can receive prompt support will greatly affect the comfort of your trip. Below are some points to pay attention to regarding the support system of a Wi-Fi rental service.

1. 24/7 customer support
   When traveling abroad, internet connections can be unstable due to time differences and unfamiliar environments. For this reason, a service that offers 24-hour customer support is extremely reassuring. In particular, if you encounter a problem while abroad, having a point of contact that can respond immediately can help you solve the problem quickly and avoid unnecessary stress.
2. Japanese language support
   While support overseas is often provided in the local language, it is also important to know whether support is available in Japanese. Services that offer support in Japanese can prevent misunderstandings and communication problems caused by language barriers, allowing you to use the service with greater peace of mind. In particular, if you have problems setting up or connecting to a Wi-Fi router, having an explanation in your native language can help you resolve the issue more smoothly.
3. Support Coverage
   You should also check the extent to which the Wi-Fi rental service will provide support, such as technical support and router replacement . For example, if your router breaks down, there is a big difference between whether they can arrange a replacement locally or whether they will only be able to assist you after you return to Japan. Also, depending on the service area, it may be difficult to provide support locally, so it is important to check in advance.
4. Flexibility in returns and cancellations
   The method of returning the device after using the service and the cancellation policy for sudden changes in plans are also important. Services that allow easy return or return at the airport are very convenient. Also, if you can cancel at the last minute, it will be easier to accommodate sudden changes in your travel schedule. It is a good idea to consider whether or not such flexible responses are available as part of choosing a service.

The quality of the support system is directly related to your sense of security while traveling abroad. It is important to choose a service that suits you by checking how they respond when problems occur and whether or not support is available in Japanese.

6. Summary

Using Wi-Fi while traveling abroad is an essential element for having a comfortable trip. First, it is important to choose the best Wi-Fi plan depending on your internet usage style and the purpose of your trip. A low-volume data plan is suitable for light internet use, while an unlimited plan is suitable for watching videos or using with a group. In addition, using offline mode, public Wi-Fi, data saver mode, and other data-saving methods are also key to making your trip more comfortable.

When choosing a Wi-Fi rental service, you should also consider the support system and ease of pick-up and return in addition to the price, communication capacity, and speed. In particular, services that offer 24-hour Japanese support are a great option in case of trouble while you're there.
