Hey Guys, I am unable to get 3g to work on US Bands with Tmo or ATT. How were you able to get them running, and what was the procedure? Simslot, etc?

All is related to the unit confiuration. To set up 3G open the main cellphone Settings, then once there on the first part aka WIRELESS & NETWORKS , select : More....once there, select :Mobile Networks. This option opens the line for 3G service selection. If your sim card is an ATT sim, the next steep is just to select : Enable 3G. Below the line should be the selected network for data use.in this case ATT. Hope this description is a good answer for your question. let me know if anythig may I help about.

I put the t-mobile in the first sim and the ATT in the second sim slot. And it worked without any problem.

Hi, the band allow in 3G of our phone are as below:* Core frequency: 1920 ~ 1980MHz, 2110 ~ 2170MHz (respectively for uplink and downlink)* Supplemental Frequency: 1755 ~ 1785MHz, 1850 ~ 1880MHz (respectively for uplink and downlink)It works well with the 3G network of USA and Europe.Thanks and hope to do business with you,AAABTC

I activated with T-Mobile in Michigan. Because of their system, the phone always registered as roaming and I couldn't get data. I changed to AT&T; , their system was 4G and it did not register as roaming. T-Mobile may have updated their systems and you may not have the same problem. It's worth a try. I am currently using T-Mobile prepaid in the Netherlands and am not having any problems.

So I had posted earlier based on the seller's data. Anyways, I just received the phone today and this is what I find: This phone is completely unlocked, 9900 model that works with AT&T (USA), Rogers, Telus and Bell (Canada). Unlike what is mentioned in the technical description, it supports the 850Mhz UMTS as well, so you get full 3G speed with AT&T. This will not give you 3G with T-Mobile as it does not support the 1700 MHz band. -------------------------------------------------------------------------------------------------------------------------------------------- Does this product have the 1700/2100 band? The seller's description does not state so. Without this band, the phone will not be able to work on T-Mobile 3G. It is a GSM phone, so no Sprint or Verizon. Also, without the 850 MHz UMTS, it will also not serve AT&T. Hence, without 1700/2100 (note only 2100 will not work and listening/transmitting frequencies are different) this phone will not get 3G speeds for ANY major US telecom operator (EDGE may be present). Can the seller please clarify?

We briefly tried on TMo LTE network in Dallas and it seemed to work. Check what band is in your area and then check the bands supported by this device.

It is quad band not tri-band. The conversation part will work on both Att and Tmobile. However the 3G internet is in a different frewuency. Therefore the American version is only good for Att. via 850/1900 HSDPA plus GPRS/EDGE capabilities. Tmobile uses frequency 2100 for 3g.

Hi. Idk if is gonna work or not, I tested with the Tmobile 4G LTE broadband sim card the speed is slow on this device, I mean is very. ... very slow, on the monitor show only 2G speed, not 3G as advertised. I guess you can contact the seller, maybe they will give you the answer.

It seems to support the 850, 1900 & 2100mhz 3g (HSPA/HSDPA/UMTS) frequencies. I bought 1 for my mom hoping that it would work for T Mobile's 3g here in the States. It does pick up here and there in the Dallas Texas area but usually remains at 2g for most of the time. that would mean that this version does not support the 1700 mhz frequency. as someone else already replied, t Mobile is rolling out there 1900 frequency coverage to support the iPhone so it is getting better. the description on this item doesn't specify which version the phone is, but multiple types exist, however the 1 I purchased from Amazon was , apparantly, the 1900/2100 frequency type.

Hi there. Just check the band TMobile works under. I use it at 1800. It is fantastic.

Hey,this is PriceAngels. In US, 3G band for AT&T is 850 MHz, 1900 MHz(WCDMA) 3G band for T-mobile is 1700/2100MHz, 1900MHz(WCDMA). For this phone, it supports 850 or 2100MHz. So you can use AT&T SIM and make sure that they support 3G in 850MHz band in your area by contacting AT&T service.

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.

Greetings. Here in Venezuela to worked perfectly as a band using movistar is 3G UMTS / HSDPA: 1900Mhz. Find that in your copies I guess it's the same band, and if so would work perfectly.

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).

When I cam home to the US I purchased my sim from AT&T.; It works great. I was using it in Brazil and using a TIM sim.
