Sim card suddenly stopped working on M7200, but works on other phones
I've been using M7200 for 2 years now but all of a sudden the Sim card exclusively used in M7200 isn't working anymore. It's Connection Status says it's Connected but no Internet at all.
The Sim card is working on other phones so I can confirm that the Sim Card only stops working on M7200. Tried using other sim although it doesn't have any Data, I was able to reach the Sim card provider's Homepage.
We have built in a lot of APN profiles for common mobile carriers in the world, that’s why MiFi devices usually can be plug and play, but if your carrier has updated their APN profile or some kinds of SIM card needs different APN profiles without our notice. In such cases, SIM card can be detected and there is good 4G signal but Connection Status shows “Disconnected”
Solution: Check if there is other available profile in the list for your carrier, or create an APN Profile manually by yourself.
The following information will be needed to create a profile manually: Profile Name, PDP Type, APN Type, APN, Authentication Type, Username and Password.
Profile Name can be anything you like such as your carrier name etc., but other parameters need to match with your carrier, if you are not so sure, please contact your carrier.
Two methods to create a profile manually:
1) on web interface of the MiFi device, please go to Advanced->Dial-up->Dial-up Settings page. Click “Create”
For more details, please refer to How to troubleshoot if there is no internet connection when using 4G Mobile Wi-Fi(Case 1)
If it still doesn't work, please contact local support for further help.
