I have a connectivity issue after installing a system update. I originally purchased this S9 while under Verizon contract, a few months ago I switched to Straight Talk without issue. I installed the latest android system update yesterday morning and now I don't have any mobile data connection. I can still make phone calls, but if I try to use a browser or an app tries to use mobile data, it doesn't work. I also get a setup wizard message that says "sim card is not from Verizon wireless". That message has shown up before, but I never lost mobile data before. I have reset my apn, check the network selected, etc and the problem still persists. Any help would be greatly appreciated.
