I'm on the same plan that I've been on for years although I did add a line about two months ago and upgraded my phone fro an iPhone 8 to an 11. I bought the phone so my plan shouldn't have changed. I'll talk to Verizon about it.I think it’s your plan. Verizon doles out bandwidth to people who pay $5 - $15 more per month for each phone on the plan. Buy the bottom feeder Verizon plan these days and your in line behind the others who pay a little more for priority bandwidth. I’m not a fan of that, but it’s the price you pay.
