Why don't stores sell iPhones w/T-Mobile carrier?

Does anyone know? I've been trying to trade my phone in && every store I've called told me they don't sell Tmobile iPhones. WHY?! What else can I do?

Just go to a TMobile store, they should have them in your area.

  • Why don't stores have Wi-Fi for iphones? They have like 40-50 networks in walmart but every single one of them needs a password to get in. And there can be only 1 or 2 bars if you are lucky in the store. How come they get to get away with it Why does mcdonalds have free Wi-Fi but not walmart
  • Why don't iPhones work well? IPhones break easily and are laggy? Hi. I have an iPhone 5 and I have many problems with it. Whenever I type on my iPhone 5, the texts that I type come out like 5 seconds after I type them. It's very unresponsive and lagging. My previous iPhone broke in just 2 years. Is Nokia a better brand than Apple?
  • Why doesn't T-Mobile sell iPhones as soon as they get released? I think one of the main reasons they are behind is because they take a month or two to start offering the new iPhone model to their customers so people flock to Verizon, Sprint, and AT&T
  • What stores sell nano sim cards for sprint? I have an Iphone 5c that's connected to sprint. I don't think it's unlocked, but what I'm wondering is. I'm stuck at the activation screen on the phone, and I can't do anything, because I don't have a sim card. So instead of buying one online, and having to wait 11 days. I thought why not just go pick one up. I called sprint and they said they don't sell them. So where could I buy one in store?
