Smartphone: Vivo Y51
Problem: Remove Replace Insert Sim Card
Description: Something is wrong with my service. It does not show and says no service even though I am in a place with high service. For some reason when I open apps like Google Maps or Pokemon Go, the service suddenly comes back, and when i exit the service goes away again. The only thing in common with Google Maps and Pokemon Go is that it both uses a high accuracy of GPS location thingys. I have tried rebooting my phone as well as removing and putting back the sim card. Still no use. This phone is new so i dont understand the problem.
