Could this be used with my existing T Mobil SIM card and with an international carrier that uses GSM?

Yes, if the phone has the capability of using T-Mobile's frequencies. I don't recall what frequencies T-Mobile uses but you can easily check with T-Mobile. There is usually no problem at all making calls or text messaging. But to get cellular data for all other things when a wifi connection is not available you need to have the correct access point name (apn) settings for the carrier you are using. The issue with all iPhones is that you can not directly access these settings like you can in an unlocked Android phone. I did not have to change the apn settings for AT&T cellular data, but you may (probably) need to for T-Mobile. Ask T-Mobile how to set the apn settings for T-Mobile cellular data to work. There may be a simple program to run from the T-Mobile website or they can do it at a T-Mobile store. Also make sure the phone has the capability to use the frequencies that T-Mobile uses. I think they list the frequencies the phone can use in the description. Make sure one or more of these frequencies is a T-Mobile frequency. For an international carrier you have to find out the frequencies used in the countries you will visit and make sure the phone can operate on those frequencies. You also need to find out the apn settings for the international carrier and how to set them on the iPhone. Setting apn settings is easy to do on an unlocked Android phone because they can be directly accessed through the programming settings on the phone. You just need to find out what they are and enter them. Hope this makes sense.

well, what I can say is: this is a Global phone, and works with two sim cards, I live in Dominican Republic and I use my phone with two different sim cards from two different companies. so, if ''t-mobile'' use sim cards I'm pretty sure your phone will works for sure!!!

You should be able to... It's unlocked so it should be able to work with a Tmobile SIM, and it works on frequencies GSM 850 / 900 / 1800 / 1900.

Yes,this phone can be used with any GSM carrier worldwide.TMobile will work because I am on Ultra Mobile which is an MVNO on T Mobiles towers.I tested an H20(Att Network) sim also and it works.Be sure to manually set your APN settings to match T Mos. P.S...it really is a great phone,for the 2gb ram the price covers.Please if you buy...get a generic case for a galaxy 3 or so.I have already broken my screen(cried and cried).The phone is so great I will buy another because I do not think parts are available easily for this rare phone.

If you mean international roaming, it won't work.Can you get a local SIM wherever your destination may be, if you have an unlocked phone?

I think you should be able to use it on any GSM carrier (including T-mobile) if you buy the unlocked version of the phone.

Yes, you can use your T-Mobile SIM card, virtually you can use any SIM card from any carrier. Unlocked phones can be used anywhere in the world.

Yes, as long as your phone uses a sim card you can use any unlocked phone. T-mobile however has a few issues. The T-Zone or myFaves features won't work so if you use those features you probably wouldn't want an unlocked phone.

Definitely, t-mobile send me unlock code which I will to its buyer, it means it can also be used with other GSM carriers.

Yes you can use it with AT&T; and T Mobile and any carrier that uses a sim, but I recommend you don't buy this phone, the battery life is no good and the phone doesn't ring or make any kind of sound for that matter, complete waste of money.

I checked it out. And yes you can, because the cards are for UNLOCKED phones. This phone is a quad band so it has both a CDMA and a GSM card slot. AT&T; is GSM so it should work with any unlocked GSM phone, same for T-MOBILE. I am not certian about Verision phones, because I have never worked with them before.
