How do if I know if my device will be compatible with the Japan data SIM?
Please check at GSM arena if your device is W-CDMA / HSDPA / HSUPA 2100MHz or 800MHz
What phone models are supported?
Our SIM card is for UNLOCKED devices, please make sure your device is SIM-free.
If you are not sure, please enquire about our WiFi hotspots for hire (email: firstname.lastname@example.org)
We have no refund policy for the devices that are not on the list below.
One customer who had a problem due an iOS upgrade, found the following method worked:
First turn off -> insert other SIM (your original SIM) > turn on -> wait till it finds signal -> swap SIM with Japanese SIM -> done, working!
microSIM = Micro SIM
USIM = Mini SIM
> tethering not supported on most Apple products (except for iPhone 4S, 5 and iPad 2), if you want tethering use in an unlocked hotspot supporting 2100 and 800 mHz
