I got a Galaxy J7 for a decent price online. It came with a Tracfone plan. I went through the 1200 minutes included, in 2 months. Now I want to switch providers for unlimited talk and text. (Which Tracfone doesn't have) I signed up with Simple Mobile, but phone won't recognize the SIM card from Simple. Do I just need to throw the phone away? I can't stay with Tracfone for 12 months. It would be cost prohibitive. Now I've had no service for four days. My grandkids can't even help me this time.
