Can this work for 4G AT&amp;T?

If the phone is unlocked any carrier should be able to host it. (this is my understanding anyway) If at&t has 4G LTE service in your area then this phone is compatible, it just may need to be turned on. Once you have a carrier you can just Google "turn on 4g Samsung Galaxy S4", there are many sites that will walk you through. Super easy though. Hope this helps

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

It for sure works with 3G.... I don't have 4G in my area so can't say for sure about that.

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.

I don't think so. I bought this as a backup device in case my primary phone fails, so I had to turn it on to check. In settings, I checked the network information and all it referenced was 3G. No mention of 4G. Hope this helps.

We took ours into AT&T; to get it set up and it works with their 4G network with no problems - can't speak to other GSM service providers.

I bought this phone and actually is working in 4g with Digitel (Venezuela). I dont know if the phone works in that way with At&t.

It probably will, but I'm not certain as I used it in. California. It works on most networks. I don't know if there is 4G coverage where you are going. Best bet is to call or email them.

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

No LTE with AT&T; here, just 4g. But your local tower could be different. Verizon appears to work with LTE.

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).

Not sure. We're using it with T-Mobile which does not offer 4g as far as I know.

Yes, I use the Straigth Talk AT&T sim. It does not support the AT&T 4G LTE data network. I am using the phone in Germany to answer question using an O2 sim card I purchased at a grocery store in a small village near Cologne. It also worked with the O2 sim during a day trip to London.

Thanks for the interest. This phone works with : COMPATIBLE TO USE WITH WORLDWIDE NETWORK SIMCARDS THAT WORKS ON : 2G Quad-band GSM support: GSM 850, GSM 900, DCS 1800, PCS 1900 MHz and/or 3G Quad-band HPSA/UMTS (BANDS 1,2,5/6,8) support : UMTS 800/850/900/1900/2100 MHz and/or 4G Quad-band LTE (BANDS 3/7/8/20) support (LTE 800, LTE 900, LTE 1800, LTE 2600 MHz) What above means is with regard to AT&T USA, it will work on AT&T on 2G & 3G bands, will not work on 4G as AT&T uses different 4G types than the one phone is compatible with. Thank you. KICKmobiles
