How to check if your android device is compatible with our SIM card

Following the previous post "How to check if your iphone is compatible with our SIM card", this post will explain how to check the compatibility of android devices with our SIM card.

The devices that have been tested are listed on our website, however, there are many more compatible devices that we don't know. You can check if yours will work by checking the specification of the device.

1. Find out the model number

On your device, go to
Setting>About phone>Model number

Or, usually, the model number is indicated on the back cover or the side of the device, or on the sticker attached to the device. Below photos are examples of SONY XPERIA ST27a and GALAXY S4 SC-04E. The model numbers are underlined in red.

*IMPORTANT*
The model number you need to find out is NOT the brand name such as Samsung, or just GALAXY S4. There are many models for GALAXY S4, and you need to find out what model of GALAXY S4 yours is.





2. Google the model number

Google the model number to find out its network specification.

3. Check the model's network specification 

Check out the section that says "Network", "Frequency" or "Cellular and Wireless". There you will find the necessary information.

What networks is your device capable of functioning on?

4. Check the size of the SIM card, too

When you check the specification of the device, double check the size of the SIM card, too. Many people who order Regular size SIM card realize that their device actually needed a Micro SIM after receiving the SIM card. Please check the size of the SIM card and order the correct size.<


5. These are the networks/frequency our SIM cards work on

4G(LTE): Band 1 (2100MHz), Band 19 (800MHz), Band 21 (1500MHz)
3G(W-CDMA/HSDPA/HSUPA): Band 1 (2100MHz), Band 19 (800MHz)

Ideally, your device can connect to all the above: Band 1, 19, and 21. Then you will be connected in most areas in Japan.

- If your device can connect to Band 1, you will be connected in most cities.
- Band 19 covers suburb areas. If you are going to be in mountains or suburbs, it will be helpful to be able to connected to this band in addition to Band 1.
- Band 21 provides extra speed in cities.

6. Make sure the model is not Region-locked.

Some brands sell different versions in different regions. Sometimes they are region-locked. If it is region-locked, you cannot use SIM cards from different regions or you are not supposed to.

7. Decide whether to book a SIM card or a mobile wi-fi

If your device is compatible, please book our SIM card!

If your device is not compatible or if you are not sure about your device, or if you want a stable connection in Japan like locals do, we recommend you book a mobile wi-fi.

Hope this helps!
