So there is no GSM Network 3G on this Nokia Lumia 720? I plan to use here in the US for a month (with an AT&T sim card) and to take it back to France.

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.

I think you'll need a smaller sim card(micro sim). Perhaps the sim card can be cut down, I'm not sure about this. I've had an E71 and some other various Nokia phones. The 720 sim is smaller than my E71 sim.

I have a T-mobile sim and a Tel-cel sim in mine as I travel between U.S. and Mexico. Very convenient. But this is a 3g not 4g.

Yes. It is GSM and if you buy it unlocked you will use wherever you go. Sorry my English not so good, but the Nokia lumia 925 is a Great smarthphone

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).

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.

You can still use WiFi outside the U.S., but i'm not sure about 3G phone service, it depends on your carrier.

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.

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.;

It is working in my country, where we have only 3G network. But I am not sure about vice versa (3G to 4G network)

I have this machine and the 4G slot is unlocked for all GSM carriers.I was able to use the 4G with GSM carriers outside the USA. The 200MB per month is a Life Long Free service from T Mobile for Customers in the USA only.

The is actually made to be used in Europe. The 3g settings are for outside the United States so inside the United States it actually will only work on 2g. Its a good phone for callingf and texting. I don't use mine for internet.

Not, 3g only for T-Mobile. And there is not logo for AT&T.; For AT&T; you need X10a and not X10i

This phone should work just fine on the T-Mobile GSM network. However, its frequencies for 3G are for Europe ONLY. 3G will not work in the US, and users will end up with Edge speed rates. Aside from that, this is a great smartphone and replaced an apple product with no regrets so far! :-)

Dear customer, you have to verify with the carrier if it supports 850/1900 frequencies. We can recommend you a quad-band phone (instead dual-bad like the nokia 100) that will work on any GSM network. LG A275 Black Unlocked GSM Dual SIM QuadBand Cell Phone - International Version - No Warranty
