ok so at my high school where i really need cell service. verizon doesnt work ay my high school but yet at&t does. as soon as i walk 15ft into the door i get 0 bars of LTE on my phone and then no service. first of all, there are no cell phone repeaters in the building for at&t, at&t just some how works!! i also discovered that in the elementary school, in some of the rooms rverizon has no service but yet at&t gets 5 bars of "4G" (HSPA+). there are also no repeaters in that building either. the verizon tower loves to go down a lot for about 6-8 hours, although this has not happened for a while. i would like a CLEAR reason why verizon doesnt work! i just dont get it! as soon as i walk out the door bam 5 bars of LTE!! ar&t gets 5 bars in the middle of the high school and im lucky if i even get 0. its impossible to place a phone call on verizon. pleae help me!! is it a tower issue or what?? i asked a teacher and they said the walls block verizon and im like ummm.... then at&t wouldnt work if it was the walls. please help!!
