I'm a new customer using the 1 GB data account. I'm getting a very weak cellphone signal and no mobile data. I use mainly wifi so this isn't a huge issue. However, my wife is complaining about dropped calls and wants to switch carriers. I have tried to setup the APN with different settings. I can get a better signal with t-mobile settings but I lose the signal at times. This would definitely cause dropped calls. After much experimenting I reverted to the recommended APN setting but still get no mobile data. Is there anything I can do?
