Will AT&T or T-Mobile allow an unlocked phone on their network? i.e. will they accept such a phone on their network?

by definition an unlocked phone works on any network. You should know that there are differences between the AT&T; and T-Mobile networks that will affect performance when crossing between them. Example: a phone built to AT&T; specs will only get 3G service on T-mobile (not HSPA+).

I'm sure they do. But remember, this phone only allows 3G speed of the Internet. Even if AT&T; and Other mobile carrier are 4G LTE. But if you connect to WiFi you can be able to access the Internet fast, depend also of the speed of your wifi device.

I'm not sure it might be pay as you go, you can still put a SIM card in and use all the features of the phone, I have no restrictions at all and no problem with my apps

Yes, I'm successfully using the 720 on tmo.I get hpsa+ speeds and mms and visual voicemail work. Beware StraightTalk- neither visual vm or mms worked on the 720 on their network.

A related question. I would like to purchase this phone and I have a At&t; 3G sim card, are they compatible?

Yes you absolutely can operate this phone on T-Mobile network. I used ATT and Straight Talk with it.

These phones are getting harder to find. The seller must clearly state that the phone is designed to work with only AT&T; or all of the functions will not work. Steer clear of the phones that are "compatible" with multiple carriers, because functions like texting pictures will not work.

It is my understanding that this phone only works on AT&T; - it is not a true "unlocked" phone - it is "unlocked" for AT&T.;

I think unlocked can only use the same network AT&T; uses, not Verizon. Best to buy a phone devoted to the network you will use until all vendors convert the LTE sometime in the future.

Just to understand correctly... are you asking to buy my phone or are you asking if TMobile will let you buy it and a Sim card and allow it to work for you? Sorry for any confusion, just want to make sure I understand.

Yes, you can. They say the phone must be compatible with AT&T, which this on is. It has Quad band EDGE 850/900/1800/1900MHz and 3G 850/1900 MHz so it will work very well.

I did not try T-mobile. However I used it with AT&T and it works fine. Nevertheless, thir phone is unlocked, theoretically it is supposed to work with any SIM. The only limitation when is the policies and procedures of your carrier. You may need to call them and ask about their user policy on using unlock phone. But, I Bellevue lately most carriers allow the usage of unlock phones.

Since it is an AT&T; phone, you don't need to have it unlocked to use on AT&T; prepay. Just put in a prepay simcard are you are good to go. And, no, the phone is not unlocked in that it can't be used on networks other than AT&T.;

Yes it will work with AT&T; on their 3g network in any part of USA. Since this is an international phone data speeds will be lower than a locked phone to the network. You can use wi fi to connect for faster speeds.

I know AT&T; did not sell this phone. So I doubt it would work on their network. I think this was exclusively a Sprint phone, I know that is who I had when I bought the phone.

Dear Customer, Thanks for your interest on this phone. This model works anywhere in the world if you use a GSM carrier. Please check if your carrier supports GSM technology. NOTE: Unlocked phones are not yet programmed for any network. In order to access the internet and use multimedia messages, you will need to program the phone according to your carrier. We have instructions for AT&T and T-Mobile (USA only). We look forward on having you as a customer. Thanks, Gus

This unlockeddevice is compatible with GSM carriers like AT&T; and T-Mobile. Not all carrier features may be supported. It will not work with CDMA carriers like Verizon Wireless, Alltel and Sprint. It does list At&t; is the carrier which means it will have an At&t; logo and may have their carrier settings.
