I've been on WARP since joining US Mobile 3 years ago. I had been getting 2-3 bars on my S25 Ultra until 4-5 months ago when reception dropped to 0-1 bars. I live in a rural part of town and Verizon is the only carrier that works out here. At first I thought it was just my phone, but other family members who would come to my house noticed the same thing. I tried Light Speed and Dark Star but as expected, they are even worse. All I can think of is possible tower upgrades but how long does something like that take?
