About two weeks ago my (telenet) sim-card no longer connected to the network. I tried restarting the phone, changing the SIM-slot, putting in another SIM-card,… The provider has tried to reset the connection. No change! I’m getting a bit desperate now, as I cannot make phone calls, send or receive sms, nor enter 4G network. Luckily wifi is not a problem without a working SIM, but in times of corona virus, it’s quiet frustrating not to be able to contact the doctors office…
I’m thinking I should replace a part in my phone, but cannot find the module with the SIM-slots in the shop. Did I overlook? Or is this part not replaceable?
How to check if you have the latest software version is explained here.
Have you already tried to shutdown the phone and remove the SIM card. Now start the phone and let it completely boot up.
Again shutdown the phone, reinsert the SIM card and restart it. Any change?
Does the SIM card contacts look clean?
Try if you can in another phone if your SIMs are still working.
Best would be another Fairphone 2.
Perhaps there is a #fairphoneangels in your neighborhood.
