Does this work for AT&amp;T LTE and AT&amp;T 3G?

The 460101 covers both the At&t 3G and At&t 4G LTE spectrum. The unit is designed to cover from a desktop area (5 feet from the inside antenna) up to an entire room. The coverage is determined by the amount of signal strength received at the donor (outside mounted) antenna. The stronger the signal, the more range from the inside antenna.

NOT SURE I am from the Caribbean and it worked well with my provider....so i am guessing it should work with at&t.....

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.

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.

No, unfortunately not. It plugs into the 3G MicroCell to help it get a GPS signal. A 3G microcell, along with a high speed Internet line will make your AT&T; phone work where you otherwise don't have cell signal. I imagine other carriers have similar devices.

Yes I'm using it with at&t, you will get 3.5 G or HSPA+ with at&t . Therefore it will work with others GSM carriers around the world.

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.;

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

Sorry, I don't have ATT. As a carrier, however the unit does handle all 4 frequencies so it is LTE capable.

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.

Yes, works with any GSM network worldwide and will get 3G data with AT&T; and all other networks that support 850 / 1900

It will work for all 3. Depending on your coverage, I usually only had LTE or 4G

No, It's Work for LTE band 1(2100), 3(1800), 7(2600), 8(900), 20(800) - D802

For me it worked for calls, SMS, and wi-fi, no 3G (I think the bandwidth was meant for AT&T; data)

I had to configure this phone for AT&T in the US. It will work if your carrier there has a SIM card for you but you will have to get them to configure the other features like internet access, Texting, email, etc. As far as I know this phone only works in Europe for 3G service the frequencies are set for Europe. This phone is over 4 years old in design...your money would be better spent on a newer Android phone like a Galaxy S3 or S4 refurbished.

It will work on T-Mobile & AT&T.; I do not know the answer to your other question.

Yes but the phone has to be branded with your network for 3G and 4G LTE to work. For example, an AT&T unlocked phone will work 2G (EDGE) for a T-Mobile customer who puts his or her sim card into an AT&T branded phone but you need a T-Mobile branded phone to get 3G and 4G LTE. The BlackBerry Curve 9380 I bought was an Orange branded phone and being an AT&T customer, only 2G (EDGE) worked. Make sure you check with the seller what brand the Curve is
