For compatibility with our Physical Voice+Data SIM Cards, please ensure that your device meets the requirements below –

• Your smart phone handset must be fully unlocked to accept SIM cards from alternative service providers.
  
  
• At minimum the device supports the 4G Band 1 – 2100MHz frequency. For the best possible coverage we would recommend using a device that also supports 4G Bands 3 and 8 as mentioned here: Frequency Guide
  
  
• Have at least Android OS 12 installed (when using an Android device).
  
  
• The Softbank network no longer offers 3G network coverage and so a VoLTE compatible phone is required. However, we have found that some VoLTE capable handsets are not compatible with the VoLTE service provided by the Softbank network. For a list of devices we have found to be incompatible please refer to the “Incompatible Phone List” in the drop-down section below.
  
  
• You can also review a list of handsets that Softbank has tested here (you may need to translate this page through a browser such as Chrome) to check if they report the device is compatible for calls, texts and data. This link is not directly related to our service (as this list is for devices and SIM cards purchased directly from Softbank) but this can be used as a general guide when deciding on a device (in addition to checking the device meets all other requirements mentioned above).

Incompatible Phone List

Please be advised that we have not had the opportunity to test all handset types and so there may be incompatible devices that are not yet listed here.

• Your smart phone handset must be eSIM compatible and you can check this on most devices by dialing: *#06#
  
  If a 32 digit “EID” number is displayed on the next screen, this would indicate that your device is suitable for use. Alternatively, you may be able to locate the EID by going to Settings > General > About > EID (on most iPhone handsets) or by going to Settings > About Phone > Status Information > EID (on most Android handsets).
  
  Please be advised that your handset must be an actual eSIM compatible device with built-in eSIM functionality. For example, our eSIMs are not compatible with products such as “esim.me” that allow you to install eSIMs on devices that were not originally eSIM compatible.
  
  
• The device must be fully unlocked to accept eSIMs from alternative service providers. If you are not sure if your device is unlocked, you may wish to check this with your previous service provider / the original retailer you purchased the device from.
  
  
• To access the Docomo 3G/4G network, your device must also support the 3G Band 1 – 2100MHz / 4G Band 1 – 2100MHz frequencies and (for the best possible coverage) we would recommend choosing a device that also supports the additional frequencies mentioned here: Frequency Guide
