UNRELIABLE. With the new SIM cards, that are mandatory to install, the network is extremely unreliable. The app itself does not load texts properly, and many times calls don't even go through. I pay for my service and it practically only ever works when I'm on WIFI, which defeats the purpose of buying the SIM card. I have been with them for many years and I hope they figure these issues out. If they improve I will give a better review, but I fear that we will have to go to another carrier.
