few weeks ago I bought for first time FP, it is the FP2.
I am using one sim card from France, and one from Germany.
the French card is only to be available for sms and calls (in the settings mobile internet is off), the German I want to use for calls, sms and internet.
Wifi works but mobile internet doesn’t even after resetting the device.
both cards were used before in other phones and worked (phone, sms, internet).
does anyone has or had similar issues and can provide some advice?
Try exchanging SIM card slots with each other. Maybe then it works out as expected. Don’t forget to update mobile internet on/off settings and switch 2G/3G/4G in SIM card settings.
If you’re sure that the SIM on which you want to activate mobile data has a 3G or 4G connection (only one SIM will have >2G speed when two SIMs are present), then the next thing to check is whether the APN settings are set up correctly. Most operators have those settings on their website, along with instructions on how to set them. Alternatively they may offer a service to receive settings via SMS (which Android normally will then install for you).
I checked with another sim card and it was still not working. then I put back the initial sim and activated data roaming and now it’s working. Now even with inactive roaming mobile internet is working and I do hope it will continue…
unfortunately the issue seems not being fixed. the connection last few seconds and comparing to before, now each time i restart the phone I have a connection but just for few seconds (< 1 Min.).
One thing that I didn’t understand in the beginning, is that you have to set a preferred SIM for data (the same place you can set it for SMS/calls). So every time you want switch between SIM cards, you also need to change the preferred SIM for mobile data:
