I got my FP2 on December 2015. First month i just try
everything and back to FP1 because of well known issues.
yesterday my phone updated automatically and everything goes smoothly. I want to change from FP1 to FP2. But my 2 SIMs from FP1 [Micro SIM/without adapter} not recognized by FP2.“No Sim Card”. Under settings --> SIM Option --> i can´t enabled because this opton greyed out. Reboot several times / Remove and insert SIMs again change nothing. I insert back those SIMs in to my FP1 and they are working.
I insert two new SIMs in to FP2. Same problem - Not recognized. Altogether 4 different SIMs each different mobile provider/network.
I would greatly appreciate any help you can give me to solve this problem.
I have learned to check first the simplest things.
Is the golden chipside down.
On the sim you have three straight corners, the fourth is cut off.
In which corner is the fourth side of your sim. Left above or on the right side near the battery.
That is indeed very strange behaviour.
The only thing I can think you is, shut down your phone, charge it full, try again.
If that doesn’t work, clear the cache. (thanks @paulakreuzer)
Go to recovery mode?
There you can reset the system cache and if that doesn’t help make a hard reset ( deletes everything) .
That was my impression as well. But since they are very fragile, as stated in the post you linked above, I’m not sure if it’s really recomendable to straighten them. Maybe very, very carefully…
To be honest, I don’t know what to tell you. Maybe when you removed the SIMs after testing the FP2 when you got it, the PINs got a bit bent and now don’t have contact with your SIMs. But it’s really strange that this happened with both slots. I’ve been searching the forum for similar problems and found this topic, but nobody posted there if he/she found any solution…
