I got this phone several days ago from a refurbishing market. It was the Samsung galaxy s10 and it’s original carrier was Verizon but it had already been factory reset. I put in my tracfone sims card that worked perfectly fine in my Samsung galaxy s7. When I started using the phone I noticed that the text messages and calling worked perfectly fine but I didn’t think to check and see if the data worked. Now I am a few days in and I noticed the 4GLIT symbol has a slash on it and my mobile data does not work at all. I did take the sims card out then put it back again which did get rid of the slash across the 4GLIT temporarily but less than 10 minutes after, the slash came back.
Any suggestions on what I should do?
