Buy a Mifi device and go rogue. 50$ a month will get you 5GB and a 3$ Skype subscription will get you a new phone number an unlimited US calls. Mugen battery is strongly advised.

I simply don’t allow the phone companies to have any access to my devices. They can’t be trusted, as I think you’ve proven. Hypothetically, they could have bricked your phone.

P.S. punish them for their arrogance. Deny them access to your device and deny them from forcing you to pay for things you don’t need.
