While travelers to Tokyo can embrace the joys of getting lost in the big city, getting lost frustratingly without being able to book a table at a restaurant can spoil the experience. Many travelers get caught up in using just their data, without realizing the benefits of getting a Japanese local phone number.
When searching for the best eSIM for Japan travel, one needs to focus on service beyond just data. Getting a Japanese phone number streamlines many of the tedious tasks that come with using some of the local services, like getting taxis, SMS confirmations, and a whole lot more, simplifying the whole experience of your trip to Japan.
The Unseen Wall of Japanese Digital Services
When you arrive at Narita, your phone’s data plan activates. Google Maps, translation tools, and a top-tier ramen shop guide are all at your disposal. Everything seems perfect until you try to do something very simple.
You want to make a reservation at a tiny yakitori place in Golden Gai, so you take out your phone and go to the website. You try to put in your phone number, and it asks for a Japanese phone number. You try with the Japanese country code, but it’s still not accepted.
This is the initial hurdle most travelers must face. Japan is a modern country that often uses very dated systems. This is most common among small businesses, so it’s especially prevalent when a small company is not a major multinational corporate chain. They want to make sure they have a number you can call to let you know if your table is not ready or if you are running late, so without the +81, you’re invisible to them.
The SMS Verification Trap
We’ve all gotten used to two-factor authentication. In Japan, this is especially true for local apps. To use the most common taxi-hailing apps, like Go and DiDi, you have to verify your account via SMS. These apps can be more dependable than trying to flag down a cab on a rainy night in Shibuya.
If your travel SIM is data-only, you won’t be able to receive that text. You’ll be standing on the curb, while others zoom off in their pre-booked rides. This is also the case with payment apps. Japan is slowly moving away from being cash-only, but local digital wallets still require you to have a local number to set them up.
• Apps for Taxi Services: These are important because they are how you will get to your hotel when the trains stop running at midnight.
• Ticket for Concerts: Many of the ticket lotteries require you to have a Japanese phone number.
• Public Wi-Fi: Some of the paid access points will deny access to you until you provide them with a phone number.
• Contacts for Emergency Use: Tour companies and hotels prefer using local numbers because it’s easier for them to get hold of you.
Being able to receive SMS text messages makes you more mobile and flexible throughout the country. It eliminates the tedious and time-consuming “tourist tax” of running into barriers. You stop having to seek solutions and ask hotel staff to call on your behalf. You gain back your lost time.
Understanding the Rules and Regulations
You may be asking yourself why you can’t just get a phone number from any of your service providers when you travel. It has to do with something called the Mobile Phone Improper Use Prevention Act. No, this was not for the purpose of mitigating phone abuse, instead it was to mitigate fraud associated with the use of mobile phones.
This makes providing SMS and voice services to foreigners extremely complicated for travel companies. Most of them opt to just provide you with a data roaming plan. This is more cost-effective and low-maintenance for them, but it leaves you with a device that is only sort of working.
Searching for the most suitable eSIM for your travels to Japan can be a bit complicated. This is because some eSIM providers do not have the necessary legal compliance to do business in Japan. Japan has strict telecommunication regulations, and for eSIMs, it is not just a matter of flicking a switch if they do not have a local presence in the Japanese telecom industry. This is why the best eSIM for Japan travel does not have local numbers.
Local eSIM providers will issue you a local IP address. An IP address is a necessary part of using the internet, and having a local one means you can access a broader range of local Japanese websites, apps, and services. This is not about licensing – some services in Japan are protected against international access to mitigate risks of a cyber-attack.
Why Mobal Stands Out?
Most travelers appreciate Mobal because it is one of the only eSIM and SIM providers that can give you an actual Japanese phone number, voice, and SMS. This means you can call and receive calls, which is great for emergencies, reaching out to local services, or even contacting your Airbnb host.
Mobal has relay services for calls and texts so travelers can better stay in touch with friends or family back home. But Mobal went one step further and really understands international travelers who need to stay in touch with local people because they are also based in Mobal.
If the voice features are not a requirement, you can get a data-only unlimited 5G eSIM. Usually, it is cheaper than the international big-name competitors.
Using Technology for Good
In the tech industry, people tend to forget about the funding. In tech, especially telecommunications, companies are profit-driven. Mobal is different. Mobal spends most of its profit on social causes. They partner with organizations like Seibo, which feeds school children in Malawi. (It’s pretty nice to know that your data is helping someone eat.)
Just because the company is doing most things right does not mean that the service is of a lower standard. In fact, it is quite the opposite. They have a strong relationship with the regional providers, and that means their coverage is reliable. You get the same network quality as the locals, whereas some roaming customers are deprioritized.
Practical Side of 5G
5G data-only plans have their benefits, and Japan’s 5G coverage in cities is very impressive. You can download map apps, stream videos in HD, and upload photos in seconds. The unlimited aspect is essential, however, as not all providers mean unlimited when they say it.
Some providers throttle your speed after a limit is reached, resulting in 2G speeds when a text can’t even go through. Mobal 5G unlimited plan offers unthrottled speeds.
When relying on a phone for every plan on your trip, this is the service you need. It is about removing the anxiety of “how much data do I have left,” and not on a vacation to watch a data meter.
Why Internet Speed Matters on the Road?
Here are the reasons why internet speed matters.
1. Real-time Translations: Voice translations in real-time do require a stable and fast connection.
2. Live Maps: Google Maps Live View is a speed data feature.
3. Video Calls: Syncing with home without any delays.
4. Work on the Go: To attend a fast Zoom meeting, you require 5G stability.
Setting Expectations for Your Trip
Japan is an amazing dream destination. Expect to appreciate the high-tech parts and old-world traditions. Make sure to get a local Japanese phone number. This will help you connect with a more digital lifestyle and help you integrate with society more.
You will understand that citizens will interact with you more and feel more at ease when you have a local number. Customer service employees or small business owners appreciate a local number. You will cross a small but significant social gap with the number. Your number will help people, and you appreciate the Japanese social customs.
Conclusion
Having a local number alters your engagement with Japan. It changes your role from spectator to participant. Choosing the best eSIM for Japan travel allows you to leave worries behind and feel good about your choice. Enjoy your trip knowing your connectivity is in good hands.
