T-Mobile edge will work? I understand 3G won't work but will Edge work?

Yes, edge does work with T-Mobile on this phone. Painfully slow when you're used to 3G, but it works.

The international S3 is a Quad Core and the US version is a Dual Core. Beware that the international versions will not work on 3G or 4G speeds. I just got bit by this. My son's S3 will only work on the slowest network speed (EDGE). I spent a fair amount of time with the T-Mobile Advanced Tech folks and they said the frequencies of the phone would work but the Branding of the phone prevent the fast connection speeds. I was told that the cell provider can determine if your phone is not from them and they purposely limit the speed. The vendors selling international phones on Amazon are not being forthcoming with this information. Be Careful!!!

This is an unlocked phone. It will work with all gsm carriers worldwide. 4G connectivity may be a problem but 3G and edge will work everywhere. Keep in mind this is an at&t phone which has been unlocked. So you can pull up detailed technical information from the at&t website.

Since the tablet doesn't support 1700/2100 (AWS) frequency, it will only correctly work with T-Mobile if you're in a 1900MHz refarmed area. Check with T-Mobile to confirm availability of this band. If it is, you'll get 3G/4G speeds, which are usually much slower than the normal AWS bands T-Mobile uses... but still fast enough for most internet and multimedia tasks. If not, you'll have Edge/2G, and that's really not usable.

It will work - yes, you will not be able to use it's 3G capabilities since T-Mobile supports 1700 Mhz by default, and W910 supports 3G @ 2100 Mhz.

Will work only on the 2G Network: GSM/GPRS/EDGE: 900/1800/1900 MHz only ! Not on the America 3G Network ! But fast as a tablet computer !

It will work as a phone but for data you'll only get Edge speeds. T-mobile requires 1700/2100 mhz for 3g or more or 1900/2100 in re-farmed areas.

I'm currently using mine on T-Mobile with 4g, its been about a month and no issues yet. If that helps, I'm sure It'll work on any other U.S carrier.

How are you? this phone works at 2G Network GSM 850 / 900 / 1800 / 1900 and 3G Network HSDPA 900 / 1900 / 2100 T-Mobile uses 1700/2100 network for 3G. The phone will work, but I will rather call them in advance and let them know you want to connect this phone in your area. Give them the frequency compatibility and they should be able to let you know if it will work for you or not. Again, the phone will work, for voice but you have to double check if your need 3G 1700 or with the 3G 2100 frequency is Ok to use this phone for data in your area.

It should work with AT&T; with both 2g and 3g. It does not work with T-Mobile 3g in the US. It does not do data in 2g. Providing you have AT&T; 3g available in your area it should work and have data capabilities (if you pay for data).

As long as it is an SIII that is labeled "Samsung SGH-T999" then you can use it on Simple Mobile AND have 4G. If it is the ATT version, you will only get EDGE (2G) speeds. Any other carrier version SIII will not work (Sprint, Verizon, etc.)

I just got it. No, 3G doesn't work. It doesn't work with AT&T; either, just tried it today.

Al-Ei:No. As Jelly said, this phone will not work with T-Mobile USA's 3G network. (Nor will any other S60 phone at the moment). Although it will work over GSM/EDGE, this will be too slow for mobile TV.Jelly: You are partially right, but misleading, when saying T-Mobile uses the 2100 MHz frequency. It is NOT compatible with the international (UMTS-2100) band, because the transmit frequencies are different (in the 1700 MHz range as opposed to 1900 MHz). Thus, T-Mobile's 3G network is usually referred to as UMTS-1700 (or 1700 MHz).

I think T-MO's 3G/4G LTE runs on Band 4:1700MHz(D)+2100MHz(U) , and in some areas where T-MO has refarmed the 1900MHz spectrum, its 3G may work. Note his phone is designed for **3G** WCDMA at 850 or 2100, not for 4G LTE. AT&T's 3G in the US might work on the 850, and the 2100 is more for the international market (e.g. like asia & europe).

Dear, 3G networks bands depends of which one has camera, in this case description says 3G bands: HSDPA 850 / 900 / 1900 / 2100 and TMOBILE i know work with 1700, and camera never will work 3G with this carrier, and i don't know if Works EDGE, because only says 3G. Maybe you may use AT&T;, with this will work 3G. but is better if you can ask your network provider, because i am from outside USA.

i have T mobile and it DID NOT work on 4G/LTE for me. It's not compatible with the US carriers and only picks up 3G in my experience.

From what I can tell, this device will work with T-Mobile and AT&T.; There is one caveat, however; if you are looking for 3G support, you will need to use with T-Mobile. With AT&T;, you can still place voice calls (and possibly use EDGE, but I am not 100% positive about this) but not 3G.
