I got the phone from a friend, did a factory reset. then turned it off and plugged in my T-Mobile sim card then restarted it. it picked up my sim card and contacts but will not let me call, no signal
It may not be compatible with you sim. If you have t mobile as your carrier then it won't work with tracfones. the IMEI is set to tracfones network and not on t-mobile's networks. You could have your friend call tracfone and see it they will unlock the phone. As long as your friend had complied with there terms of service they might unlock it for him. Then you should be able to use it on t-mobile's network. Also check your apn settings.
