The 9360 is unlocked with the Quad band. It works with AT&T;, Verizon, and T Mobile. When I use it in South America and North America work the same(it switches from one operator to the local one) Even in Europe ; so Quad Band is unlocked and works.

Hey,this is PriceAngels.In US, 3G band for AT&T; is 850 MHz, 1900 MHz(WCDMA)3G band for T-mobile is 1700/2100MHz, 1900MHz(WCDMA). For this phone, it supports 850 or 2100MHz. So you can use AT&T; SIM and make sure that they support 3G in 850MHz band in your area by contacting AT&T; service.

I work for Nokia and wanted to answer the questions in this thread. The Nokia N900 is an unlocked quadband GSM device with tri-band WCDMA meaning it will work on almost any GSM network in the world for voice and data including AT&T; and T-Mobile USA. The Nokia N900 utilizes the 900/1700/2100MHz network for 3G capabilities. These network bands are compatible with T-Mobile USA's 3G network, among others that use this spectrum. We have not announced a version of the Nokia N900 that supports AT&T;'s 3G network.

Yes it will work with at&t; as its quadband and operates on all four frequencies.

IF you are a current att customer on GSM, as I am, all I had to do was stick in the old sim and turn it on. The quad band capability does a "searching" for service. After a second it finds ATT and hooks up. Good luck, it is a pretty good phone, and mine has withstood a couple of drops to blacktop.

The phones we sell are all unlocked from factory - quad band GSM frequencies: 800 / 900 / 1800 / 1900 MHz, making it compatible with all the major GSM networks in the world. The 850/1900 MHz bands are mainly used in the US, while the 900/1800 MHz ones are available in most other countries worldwide.

Yes you can, as I am doing the same. However the c6806(i think that's the right name) has LTE bands for AT&T.;

STRAIGHT TALK - You know, a little bit unrelated, but I just got my Motorola Defy XT at Walmart, but I was told by the sales person that it ran on the AT&T; network but I just found out that it's actually a CDMA phone, probably on the crappy Sprint network, I get very weak signals where I live. I don't quite know what to do now... Return it to Walmart and lose half my 45 bucks in airtime credit I put in, or stick w/ it... I also was planning on installing a different SIM card from Straight Talk that I have, this one by AT&T;, can anyone give me advices? Thanks!

No. This is a GSM phone that requires a SIM card. Also, the one I received is only a tri-band GSM. You need a quad band to be guaranteed to work with T-Mobile and AT&T; in all areas of the US. I'm not able to use this phone with ATT in my home area.

Definitely will work on AT&T; but there are some qualifications. On quad band 2g GSM it will work on 800 and 1900 mhz. On dual band 3G, it will work on 800 mhz. However, it will not be able to use 3G 1900 (only has 800 mhz USA and 2100 mhz 3G) nor will it be able to use LTE unless indirectly through a separate mifi device (I do this). There are some APN data settings included with the phone that should work with an AT&T; direct sim chip but may not work with the data settings with AT&T; resellers like RedPocket, H2O, etc....those would have to be manually programmed in...I don't bother with that and just wirelessly tether via wifi to a hotspot or my AT&T; mifi device.

I think the description of the product has a 3G carrier errorl for 3 bands in this type of phone, my question is whether this BB9100 amazon is already selling unlocked?

I have used an unlocked phone for it but it wasnt carrier branded i bought it from amazon and it came unlocked already and it worked. Since the blackberry was already att brand im pretty sure it should be working if it doesnt i apologize. Also if you are still iffy you can just call your local att store and ask them. Hope this helps

Shouldn't be any problem. The BB 9790 is a quad band phone and also works on the 1900 Mhz.

Yes, Quad Band, HOWEVER this version is locked to T-Mobile. If you are not on T-Mobile you need to buy the Unlocked version.
