I recently switched my S10+ over from Sprint to Verizon, in the hopes of getting a better signal at home and abroad. After activating my phone I was able to get 4g and 3 bars, but later in the day I was getting 3g with no bars or just flat out no service. I tried all the trouble-shooting steps, and I'm at the point of trying a factory reset. I talked to customer service and they seemed confused since i'm in a coverage area. I'm just really confused on how that my mom and sister are sitting beside me and getting excellent service, while I get a no network error.
