Hola Eduardo. I brought this exact phone to Uruguay and when i changed the sim to micro sim (antel) it worked perfectly with my 3G contract. Theres no mode selection, the phone simply works at 3G altough the display says 4G. After that, i did change my contract to 4G and now the display says 4G LTE. When it doesnt find the 4G LTE band it works at 3G showing 4G. It is too often that it does not find the 4G LTE band.... hope this helps. Do not hesitate in contacting me if u have more questions. 099580683

I think T-MO's 3G/4G LTE runs on Band 4:1700MHz(D)+2100MHz(U) , and in some areas where T-MO has refarmed the 1900MHz spectrum, its 3G may work. Note his phone is designed for **3G** WCDMA at 850 or 2100, not for 4G LTE. AT&T's 3G in the US might work on the 850, and the 2100 is more for the international market (e.g. like asia & europe).

I'm using my duel sim Asha on the (New Cricket) AT&T; bought Cricket and it now uses AT&T;'s GSM network. I have a feature phone plan. Meaning voice and text messaging. $25.00 a month! I live in a city that you can't go 6 blocks and not find free Wi-Fi and thats how I use it. That said; if you have a data plan, it will work that way too. In the phone settings you can set it up for, data only, Wi-Fi only or both. Another thing, if you have the phone set for both, it will look for Wi-Fi first. Saving on a data plan. The phone has the best of both worlds feature and data!

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

IF you are a current att customer on GSM, as I am, all I had to do was stick in the old sim and turn it on. The quad band capability does a "searching" for service. After a second it finds ATT and hooks up. Good luck, it is a pretty good phone, and mine has withstood a couple of drops to blacktop.

Flagship phones like this don't vary from providers. Only their programming to work with the different networks is different. The new S4 active would be different, but I think that is only on AT&T; network at the moment.

I think unlocked can only use the same network AT&T; uses, not Verizon. Best to buy a phone devoted to the network you will use until all vendors convert the LTE sometime in the future.

It does not support LTE but does support the Hi Speed T-Mobile version of 4G known as HSPA. I'm in one of these T-Mobile areas and can get close to 20mbps downloads. I believe ATT network 4G uses LTE and that is not supported.

It depends on which model it is. SQN100-5 works on AT&T; LTE, 3G, EDGE and HSPA+SQN100-3 works on AT&T; and T-Mobile but you will not get AT&Ts; LTE bands with that phone. You will only pickup EDGE, 3G, HSPA+ on AT&T.; If you

I'm using this phone with Straight Talk (on AT&T; network) and the phone functions, but I'm not getting an LTE connection (only HSPA). Working to resolve the issue.

This particular model is the international version which has HSPA, which can be branded as 4G but is slower than 4G LTE. If you want 4G LTE you will have to get the US version from AT&T.

Hello Alyssa,Be sure to purchase one that uses the ATT network. I've purchased 3 of them an the SIM cards and plan from AT&T; store work great! I'll get a 5 next year.

If you use this phone for 2G network, it supports both at&t and t-mobile. This cell support 3G WCDMA 2100MHz. T-mobile&#65306;1700/2100(WCDMA); AT&T&#65306;1900MHz(WCDMA); So you can use T-mobile to access 3G network with this phone.

According to Wilson LTE works on all carrier with this. I know for a fact the 3G works though because I've had someone at my house with AT&T; and they had perfect 3G signal. I currently have Sprint as well and the LTE works flawlessly with it.

In the US, T-Mobile would be the better choice for 4G LTE support. Since this phone does not support the 700 LTE band used by AT&T;, you will not get LTE support on AT&T; in most areas. It does support both LTE bands used by T-Mobile nationwide.
