This is probably going to be a long post but please bear with me. My mom, sister, and I all have unlocked iPhones with unlimited texting. My mom has the $9.99 data plan on her phone, and has had it for a while. Me and my sister do not. However, about two years ago or so I discovered that if I enter "internet2.voicestream.com" as my data APN, edge works. After looking online and seeing that this worked for others too, I concluded it must have something to do with the texting plan. My sister and I did this for a while with no extra charges on our bill. A year or so ago my sister's data stopped working out of the blue, and she would just get the "web2go" screen or whatever it is when trying to access the internet. Mine continued (and does continue) to work. Here comes the problem: on our last bill (maybe last two bills, actually) me and my sister got charged $50 EACH for the new pay-per-use plan T-mobile has implemented. I've seen that this is a pretty widespread issue, even for people that don't use/have a data plan (even people that don't even have an APN entered), so I feel like it's not just because of the free internet we've been getting (especially since my sister's internet doesn't even work). My question is: How should we go about fixing this issue? Just call and complain that we don't have a data plan and don't want one? I assume they know the exact amount of data I've used, and they might bring up that it's a higher amount than normal for someone who doesn't use data (I think I use about 90MB a month). What should I say about that? Maybe that I use MMS a lot and that must be the culprit? Any chance of me still being able to use free edge after (if) this gets cleared up? TL;DR Got socked with data charges after the new Pay-per-use plan went into effect, what should I do?
