The ‘Japan Voice + Data SIM Card’ product we offer utilizes the Softbank network and as this network no longer offers 3G coverage (Softbank started decommissioning their 3G services on April 15th 2024), your device must support the 4G Band 1 – 2100MHz frequency and it must also support the ‘Voice Over LTE’ (VoLTE) feature in order to place and receive calls.
A recent report from Softbank also suggests that the device may need to support at least the Android 12 OS (in order to be compatible with the VoLTE service) and so we would recommend checking this as well.
Unfortunately however, we have also found that some VoLTE capable handsets are just not compatible with the VoLTE service provided by the Softbank network.
If your device is listed below, our extensive testing has found that you may not be able to place / receive calls when using this service.
If your device is affected by this issue and you require the ability to place / receive calls, we can only recommend that you use an alternative method to place a call (such as WhatsApp or FaceTime for example) or that you consider switching to an alternative handset.

Please be advised that we have not had the opportunity to test all handsets and so there may be some incompatible devices that have not yet been added to the list above. However, we will continue to investigate and update this list based off our findings and feedback.
If you are experiencing any issues with the VoLTE service and your handset is not mentioned in the list above (and you have already tried following the instructions found here), please send an email to: support@mobal.com
In your email, please provide us with the make / model of your device and your current location. Please also include screenshots of your current APN profile settings and of the ‘Mobile Networks’ menu (the section showing your current ‘Network Mode’ / ‘Preferred Network Type’ setting and any settings related to VoLTE).
