๐Ÿ“ถ + ๐Ÿ“ž Using My 050 and TOP SIM Together

A smart way to combine data and calls in Japan 

In Japan, many prepaid SIMs provide data only, which is perfect for internet access — but what if you also need to make or receive calls? The combination of TOP SIM and My 050, Brastel’s VoIP calling app, offers the best of both worlds: fast mobile data and a reliable phone number for both domestic and international communication.

This simple setup is ideal for visitors, students, expats, and anyone who wants full mobile functionality without a long-term contract.


1. What is TOP SIM?

TOP SIM is a prepaid data SIM that lets you stay connected anywhere in Japan — no contract, no registration, and no monthly bill.

You can choose from flexible data plans such as:

  • 5 GB – valid for 30 days

  • 10 GB – valid for 30 days

  • 15 GB – valid for 30 days

  • 25 GB – valid for 30 days

  • 50 GB – valid for 60 days

If you don’t use all your data, the remaining balance rolls over for up to 180 days. You can recharge at convenience stores nationwide or directly from the TOP SIM app using a credit card.

TOP SIM is available as both a physical SIM and an eSIM.
With eSIM, activation is instant — no need to wait for delivery or insert a card.
For eSIM users, activate via the QR code for iOS, or manually enter the activation code for Android, and your line is ready immediately.
Configure the APN settings if necessary, and you’re good to go.

Our TOP SIM uses Japan’s top-tier networks, ensuring stable and high-speed data for browsing, SNS, navigation, and streaming.



2. What is My 050?

My 050 is Brastel’s VoIP (Voice over IP) calling app, designed to let you make and receive calls over the internet.

With My 050, you can:

  • Make domestic and international calls easily through Wi-Fi or mobile data

  • Enjoy clear audio quality and low rates worldwide

  • Manage your balance, SIP password, call forwarding, and more directly in the app

You don’t need to request a phone number if you only want to make outgoing calls.
However, to receive calls and access additional convenient features, you’ll need to complete a simple eKYC (electronic identity verification) process to obtain your own 050 number — a standard Japanese VoIP phone number.

Once verified, your 050 number allows others to call you from Japanese landlines, mobile phones, or even from overseas, just like a regular phone line.



3. Why use them together?

When combined, TOP SIM + My 050 provides the full functionality of a mobile phone — without the restrictions of a traditional contract.

5. Real benefits for everyday life

Using TOP SIM and My 050 together is especially useful for:

  • Expats who want to keep a Japanese number even when traveling abroad

  • Tourists who need immediate data and calling options upon arrival

  • Students staying short-term or mid-term who need affordable communication

  • Remote workers who rely on stable data and voice access for meetings

  • Japanese users who may use it as a secondary line when their main plan runs out of data, or as a primary low-cost line by combining TOP SIM with My 050 for both data and voice

You can make and receive calls anywhere in the world as long as you’re online — and your 050 number remains active even if you switch devices or SIMs.


CONCLUSION

If you want a complete, affordable communication solution in Japan — data + voice without contracts — combining TOP SIM and My 050 is the smartest choice.
Enjoy full connectivity, flexible control, and transparent pricing wherever you go.
