Rephone doesn't see sim card

Last week a friend gave me a rephone kit. A wonderful present! I assembled it and all things look if they’re working. I inserted a new sim card, but it doesn’t recognize it. It keeps saying sim missing. I tried a sim card of an other cell phone and it worked neither. The new sim card worked properly in the other cell phone. May be it has something to do with the network, however the provider is still keeping up the 2G network.
Please, can someone help me with this problem?

Hi Marten,

Thanks for the feedback.

I am thinking about:

CASE A - it could be a bad connection between the SIM card and the card slot here in your case.
CASE B - Every time you re-insert the SIM card, you need to reboot the RePhone

Could you please try the following:
Case A:

1. Please check the direction of your SIM card, see if you have inserted it other way around
2. Try to gently push in the card a little bit
3. If your RePhone still shows “NO SIM” on the screen, use a tweezer to SLIGHTLY lever up the metal connector on the SIM card slot , DO NOT BE TO HARD OR YOU MAY BREAK IT.

Case B:
Turn off the rephone, re-insert the SIM card, then turn it on again to see if it works.

Please let us know if the problem is solved.
Thank you!

I had this same problem: The Xadow GSM+BLE module on my RePhone was not recognizing my Ting (USA) 2G Nano SIM. In the end, it was a seating problem with the FPC Cable. For anyone else struggling with this issue, you might try to re-seat your FPC Cable.

Also, this may just be coincidence, but:

• I noticed that if the FPC Cable was not seated well on the Xadow Touchscreen module connector end, there was a problem with the Display.
• I noticed that if the FPC Cable was not seated well on the Xadow GSM+BLE module connector end, there was a problem with the SIM card being recognized.
