Hey,
Take the battery out of the phone and locate the sim card. Remove the sim card and get an number 2 pencil with a good eraser and use the eraser on the gold contacts on the sim card lightly to clean up any corrision that built up on the contacts ( it will look black) . If that doesnt work go to your cell phone providers store your sim card got fried. they can set u one up for like $25
Thank you SO much. I didn't use an eraser; I rubbed it on my shirt & also rubbed the contacts on my battery. It worked fine after that!
My phone keeps going off every 5 minutes even with a new battery..phone is TM 506 and sim card is at least 7 years old...this is my second 506 and both phones did the same thing...will this sim card fit into the tm 717?
