The phone works great on AT&T; 3G. Strong and reliable signal. It should work on any carrier as long as you have a sim card for the carrier you want, but the best is probably AT&T.;

Yes, but it is tricky I've found 3g to only work with AT&T; not T-Mobile. Its not top quality and picture is OK. It does everything it says but not the best. For the price its great cause it works it does what its supposed to far from a Samsung or anything comparable but it works. So for functionality great but if your into to the big box devices that offer beautiful pictures and flash camera the Cadillacs this isn't it. More like a Isuzu. usury

It works with AT&T; Network but it has nothing related with them. No AT&T; logo on it!

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.

Thanks for your interest on this phone. Yes, 3G WiFi. 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

Hello: usually it works automatic. If the internet does not work automatic you might have to set up the APN settings. That is true for any Factory Unlocked phone.

Yes it should work automatically. Mine did, you may have gotten the wrong version or gotten a faulty one.

I use my phone on a GSM network in Jamaica and it works perfectly. AT&T; is GSM so it should work.

This model is unlocked, so yes it should work with AT&T.; I've used it with many carriers in a couple countries with no issues. BUT THIS PHONE IS TERRIBLE, IS THE WORST I'VE HAD, IT IS NOT RELIABLE AT ALL, IS REALLY SLOW, CRASHES A LOT, HAS ISSUES WITH THE SCREEN BRIGHTNESS, VIBRATING, SENSORS, BATTERY, I DON'T RECOMMEND IT AT ALL.

I got this phone through Cricket, who uses AT&T's network. Therefore, it will work.

It should because it's GSM unlocked. It will work on any GSM network. GSM was the global network introduced first by AT&T. Check to see if you have a GSM network provider.

Yes, it does. It was no problem working on AT&T. I will also recommend you to browse through Amazon feedback on how to configure the MMS and Web browser settings as AT&T will not be helpful in assisting you on an older outdated model. You search for Nokia C3-00 mobile phone and in the feedback "Nokia C3-00 Cell Phone - Awesome Product!!, May 23, 2011" you will get info on how to do AT&T Web & MMS configuration. However, as I wrote in my review, my honest opinion is to avoid this model as invariably the chances your touchscreen will malfunction are very high.

the 3G network of AT&T is WCDMA, and this phone support WCDMA, so it will still work with your SIM card
