I highly suggest staying away from T-Mobile if you like to receive your phone calls, get voicemails when they are left, and not have to restart your phone constantly, or deal with interruption/disconnection on, at times, a daily basis.
I switched from T-Mobile because I was tired of paying $220.00 a month for two cell phones with AT&T. We've had these phones for at least two years now, and I eventually added two additional lines making my phone plan a total of four lines. I have never missed a payment and have only ever been late once or twice due to a bank error.
They lied when they said they would buy out our contract and phones with AT&T. We still owed AT&T over $500.00 which went to collections, but is now paid. They did this to several people I know, including businesses.
I thought at first that all of our connectivity issues, and call issues, and voicemail issues, etc. were due to the phone itself, but it turns out that almost EVERYONE I know with TMOBILE has said the same exact thing. In fact it's a huge joke. I have family that never paid their bill and switched because they became so irate. I know of another customer who was made several promises, and not only has the same issues, but now they owe T-Mobile over $1500.00 for devices so they can't switch even though they were lied to by a T-Mobile rep. My mother and brother are on my phone plan and pay their share of the bill, but they have had it. I am not exaggerating when I say that everyone in our area that I know who has TMOBILE has a provider hates it!
Here's the kicker. I have called, I have gone into the store, but still nothing. When I went into the store, I asked about switching providers. They just gave me the date that I could switch without owing a bill, and the same happened when I spoke to a rep over the phone, and again, I have never missed a payment. I have been lazy, but we will be switching. They make me want to slam my phone in their face.
