I have a Samsung Note 10+ (unlocked verizon) that I bought about a year and a half ago. Checked to make sure it would work with ST, did the sim, all that and activated it. Well, it wouldn't let me make calls/send texts when I left the house. My husband called ST for me, whatever they did worked and it was fine for a bit. Well, it started up again and it also won't let me send/receive photo MMS either, whether I'm home or not. I've spent hours troubleshooting it, nothing works. I'm at my wits end with it. I love my phone and I cant afford to buy another one. Any help??
