I understand that 2G protocol (for GSM) will not be supported by AT&amp;T in the near future. Does this product support the 3G GSM protocol?

Yes, it supports 2G, 3G and 4G, as long as your simcard supports GSM850,900,1800 or 1900. Thanks.

I think that's a typo or mistake. GSM phones compatible with T-Mobile or AT&T; use WCDMA protocol for their HSPA connections. HSPA is technically 3.5G in terms of speed. LTE, whether on a CDMA(Verizon) or a GSM(T-Mobile and AT&T;) carrier is true 4G in terms of speed. LTE is also a protocol for the wireless transmission of data. The differing factor in carrier LTE service is only the MHZ to which it is transmitted. Hope this clears things up and if the seller reads this, fixes the listing.

from my experience when I first got the unit I tried using an AT&T; sim card. The unit did not work as it was supposed. I wasn't able to control it remotely from my cell phone. I called the seller and they advised me to use a t-mobile sim card. I then went to t-mobile and activated a prepaid SIM card and then the unit worked as it was supposed. from my understanding AT&T; no longer has 2g capability but T-mobile does. Hope this helps. The seller's customer service is also pretty good.

Hi Eugene. You made me curious if my phone will work on AT&T; 4G Network, so I bought an AT&T; prepaid simcard with a logo of 4G LTE. I put it in and I load $40 with unlimited call and text and 200MB of data. After that I called AT&T; to activate my internet and they did. I was so happy that I was able to go to any website but only to the speed of H or H+. H+ is faster that 3G but one step down to 4G/LTE. Hope this is helpful.

As staed, compatible with 2G & 3G 800/850/900/1900/2100 & 4G LTE 800/900/1800/2600 network simcards worldwide. This means 2g & 3g with att is ok, not 4g, as AT&T; uses different 4G. With regard to your Mexican network, see if your network uses GSM Types that the phone is compatible, then should be fine. Please check with your network provider. Thank you. KICKmobiles

This phone supports both 2G and 3G . The network it supports as Dual SIMs WCDMA 900/2100MHz (3G) GSM 850/900/1800/1900MHz (2G). It means if the provider can support those network . Then this phone works .

Anybody having trouble using 3G data with AT&T? My 5800 is showing excellent 3.5G signal but when I try using data it just gives me an error message. It works fine if I keep the phone in GSM-mode though... EDIT: An extremely stupid design choice in AT&T's SIM card structure. Even though I had a 3G capable sim card, it wasn't 3G-enabled so couldn't use the data (but oddly enough could use the bandwidth to talk to people. If anyone else has this problem, just go talk to someone at AT&T.

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

Wow, great response time, VJ. Have you considered switching service to AT&T; for the 3G? Thanks.

I think this is for the international version. An AT&T unlocked version is also posted. Both support T-Mobile 3G, but only the AT&T support AT&T LTE network. This is the LT30P as it said.

It's an older phone now, and therefore only supports 3G. Or at least, that's the case with mine, I don't think they ever came out with an updated 4G version.

I like my phone its wonderful It will work with ATT GSM (2g), 3g, but NOT ATT LTE since they only support band 17, 4, and 2. This international version only supports LTE 800(B20)/ 1800(B3)/ 2600(B7).
