Is a factory unlocked iPhone 4S compatible with T-Mobile?
Will a T-Mobile prepaid SIM activate and get me through the setup process with my new iPhone?
If it is unlocked, yes. Two things though:
1) You need a micro sim from t-mobile, they have them and they are cheap.
2) Understand that an AT&T iPhone 4/4s (In America the only GSM iPhones are AT&T) will only understand the 1900Mhz frequency for 3G/4G internet. T-Mobile currently uses the 1700Mhz and 2100Mhz frequency for the 3G/4G internet. Basically this means that if you are going to use that iPhone on T-Mobile be prepared for only having access to the 2G or Slow internet. I would not spend more than the $50 plan as the 60 and 70 are just for more access to 4G.
On a side note, T-Mobile has been making an effort to roll out the 1900Mhz frequency across the USA but it is currently only in select cities like Vegas, Miami, Boston ect. If you live in a large city there's a small chance T-Mobile has or will be rolling that 1900Mhz so your iPhone will be good to use for the web.
- Will an unlocked iphone 4S work for tmobile if it isn't factory unlocked? I want to get an iPhone 4S and my friend has the iPhone 4 unlocked but i'm worried that if i get it non-factory unlocked it won't work. My uncle tried to do it a couple of months ago and apple said that if it was factory unlocked every time the phone shut off or died it would reset. I was just wondering if the same thing would happen if it wasn't factory unlocked? So if I get it unlocked everytime it will shut off it will reset? That is what i'm worried about.

- Why Iphone 4S won't read T-mobile Sim card even though factory unlocked? I have an iphone 4S and it reads Att sim card no problem, i had the phone factory unlocked and it even said Congratulations your iPhone is unlocked after i restored it in iTunes, but all it says is no service i tried two different T-Mobile sim cards. I even checked my imei number online and it said the phone was factory unlocked. Is there anything i can try, i've never ran across something like this.
