Just got a letter from sprint saying exactly what the OP said. Not roaming but "unlimited data" usage. I'm always on 4g and I used about 109gb of data this month. They said if I don't control it they will terminate my contract. That's a lot of data I know but unlimited is unlimited!!! F them!
just to clarify, as I work for sprint currently:
Updating your PRL does nothing, other than tell the phone which towers have lower roaming costs. (on sprint)
Verizon doesn't roam on any network. (I was a verizon manager as well) If you have a vzw phone, you won't roam at all.
If your using 109 gb's a month and complaining about sprint saying something to you, I would reccommend getting an actual home internet connection instead of using it for tethering so much.
As far as the roaming stuff, yes, if you roam a ton while with sprint, they can release you from the contract, but its not an automatic thing. A lot of times you will have to call cs a few times (because sprint CS sucks, and are a bunch of morons usually) and have them pull the account and see how much you are roaming and how many dropped calls, ect, are.
Oh, sweet. This argument again. Please read the 'unlimited' agreement you have with Sprint. Please note the conditions which apply. Please note what specific data activities you are permitted in the agreement. Note also the prohibited activities. Finally, pay close attention to the bottom of this contract where you electronically signed and acknowledged/agreed to all the conditions which they are well within their rights to enforce.
109gb of data is quite a bit. How does one's handheld use that much data in a month?
