Nokia 7250 "insert sim" problem - GSM-Forum

thecult · 12-16-2003, 18:44

Hello, I have one Nk7250, it seems in good conditions, I insert a sim card and power on... all good but sometimes it restarts and displays "insert sim"

I have resoldered sim card connectors, I have flashed it with prodigy... any other idea?

thanks

best regards

sometimes its when the battery contacts or battery pads are dirty or it could be uem that needs reflow or faulty.
