I bought an M2 Dual (D2302) so that I can use it mainly in Europe BUT I want to have 3G reception while traveling in the USA. The phone is supposed to be quad-band in 3G (900/2100 for Eurasia and 850/1900 for the vast AT&T network in the States). It says that it is quad-band 3G on the box, it says so in the official whitepaper, it even says so in the FCC testing report...BUT...when I enter the service menu it indicates that the phone only has 900/2100 in 3G! So, does it support the "missing" 850/1900 UMTS bands or I'll be stuck in GSM-only while in the USA?

I want a 3g enabled smartphone/PDA for t-mobile, not the G1 dont like it. T-mobile 3G uses bands 1700 Mhz and 2100 Mhz right? So if i buy a phone that supports HSDPA 2100 Mhz will it work on the t-mobile 3G data network?
t-mobile is a gsm network though, so i don't know that an hsdpa phone would work with them (first of all no sim slot)
tmobile's 3g is new and not fully released so it would be difficult to find a phone that supports their 3g (you won't find anything but the g1, and you couldn't unlock a phone from att to support there 3g because the bands are different)
This is my understanding, but if i am wrong you guys can correct me
Hi
I was told this would be a better forum for this question.
I have a huawei ideos (older non X6 version) and supposedly it is unlocked. It works with 2g/edge. It does not work with t-mobile 3g. I have looked for APN information and the info downloaded to the phone when I connected to t-mobile network is identical to what is listed on the net.
ie. I added
MMSC: http<colon><twoslash>mms.msg.eng.t-mobile.com/mms/wapenc
xxx added because I can not post urls.
Things which are odd. When choosing access network, it does not say T-mobile 3G. It only says T-mobile 2g, Att 2g and Att 3g. According to the net this phone supports the frequencies for tmobile.
gsm link for u8150 not allowed.
shows HSDPA 900 / 2100 / AWS
HSDPA 850 / 1900 / 2100 / 1700
And the wikipedia entry for tmobile
shows
1700 MHz/2100 MHz UMTS (W-CDMA)/HSPA 4G (formerly 3G[31]) 2006 2008 (3G), 2010 (Marketed as 4G) First carrier in the U.S. to deploy services on AWS frequencies. Markets HSPA+ as "4G". UMTS band IV
Not sure if HSPDA spec is same as HSPA though.
I did the trick where you enter #*#*4636*#*#* and checked phone settings. I changed the setting from CDMA to GSM auto (PRL). I also tried to hit menu and select radio band, but it pulls up an empty "Set GSM/UMTS Band" dialog. There is nothing to select.
I guess my question is, does this phone support 3G for t-mobile and if so, what setting am I missing?
thanks in advance.

I got an email from Huawei support
Hi,
Just as another data point. I got an email regarding this issue from Huawei support. They said an unlocked phone from one provider may not fully support 3g on T-Mobile. I asked them what he meant by not fully support.
Here is an excerpt from the Huawei email:
This phone is capable to be used in 3G that is correct, however if the phone is unlocked from the original provider it may not be fully compatible on 3G on the different providers network.

Moving to Q&A
three more datapoints
Hi
I got another note from Huawei. They said they don't support unlocked phones.
I talked to t-mobile support. They said the u8150 uses PPP and not RMNET. I have never heard of RMNET, and that the phone would only support 3G if it was rooted.
This seem like BS all around to me. T-mobile and Huawei.
I did test my phone with a friends tmobile sim and the phone behaved the same. ie. edge only.
Some more datapoints
Hi
This phone is available in two different frequency capabilities. Considering mine can see the ATT 3G network, it must be using the second set of frequencies. This second set is listed as usable by T-Mobile as well. Here is the info:
From the huawei spec sheet.
At the top it shows
UMTS 900/AWS/2100MHz or
UMTS 850/1700/1900/2100MHz;
EDGE/GSM/GPRS: 850/900/1800/1900MHz
According to Wikipedia
ATT
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/HSPA 3G
1900 MHz UMTS/HSPA 3G
700 MHz LTE 4G
T-Mobile
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
1700 MHz/2100 MHz UMTS (W-CDMA)/HSPA 4G (formerly 3G[31])
When I connect to wireless networks, I see three choices:
T-Mobile 2G
AT&T 2G
AT&T 3G
So I am guessing my u8150 is using the second UMTS set of frequencies:
1. 850 (since it sees two edge networks and that is only available in the second set.)
2. 850 and 1900 (since it see's AT&T 3G and it is also in the second set)
This second set of frequencies is also used by T-Mobile so I don't understand why this phone can not connect to T-Mobile 3G using my simcard or my pals.
It's all about the supported 3/4g bands. Most carrier Androids only support their networks spectrum's. Check gsmarena to ensure compatibility.
Hi,
Thanks for the info. Maybe I don't understand, but I thought gsmarena showed this phone as using both the Att and Tmobile bands. I remember when I had nexus ones was that one version was for ATT 3G and one was for TMobile 3G. I'm guessing that the 8150 is similar with the exception that huawei has not published accurate docs. ie. their docs say both frequences for all phones when in reality its two different model phones with only one label.

I apologize for not reading all of your posts
This isn't BS. It's the same issue facing Cricket phones attempting to connect on Verizon. I'm not fully up to speed but it looks like RMNET needs to be added via the kernel (edit sources and compile).
The below thread isn't specific to Tmo but it should give you some insight.
[04JAN][TMOUS]CMYLXGO's Stripped & Squashed Stock Desire HD[KERNEL:gauner1986][RMNET]
This is what Huawei meant by "may not be supported". However, if the phone connected to Tmo with SIM then it's already carrier unlocked. You now face the above issue plus prl, etc.
You face a long road ahead. My suggestion, sell the Huawei and buy a used Tmo Android.
Hi guys,
I'm looking to buy a Galaxy SIII from the States to use here in Australia, and am having a hard time understanding the intricacies of the cellular bands. I get that CDMA stuff is a no go (Verizon, Sprint) and that it seems only TMobile and AT&T are possibilities. Here is a chart with the variants and their banding listed. http://en.wikipedia.org/wiki/Samsung_Galaxy_S_III
The variants support all 2g frequencies, but I don't understand how the 3g part works. The t-mobile one in the 3g band is
850, AWS (Band IV), 1,900, 2,100 MHz UMTS / HSPA+ / DC-HSPA+

, which doesn't include the 900 that some networks use here. Will the phone use only 2G if this is the case? Will that make any difference to me? Will the AT&T one work as well?
Can someone please give me some clarification? :victory:
Below is the info for Aus carriers...
2G
2G, other wise known as GSM, is standard on almost all phones (except CDMA phones in the USA). Most new phones come with quad band GSM support. A quad band GSM phone supports 850, 900, 1800, and 1900MHz.
2G is old technology and provides a fall back position when 3G coverage is unavailable.
Australian 2G bands:
900Mhz (Telstra, Optus & Vodafone)
1800Mhz (Telstra, Optus & Vodafone)
3G
There are several 3G networks operating in Australia. 3G frequencies are usually specified as UMTS/HSDPA or WCDMA frequencies on the mobile phone specifications.
Australian 3G bands:
850MHz (Telstra, Vodafone) – Exclusive 3G band
900MHz (Optus, Vodafone) – available in most metro areas on Optus, with both Optus and Vodafone re-farming the 2G 900 spectrum in regional and rural areas
2100MHz (Telstra, Optus, Vodafone) – Exclusive 3G band
I purchased the newly released UMI X2 Android phone. I am unable to use the TMobile 3G network. I am only able to use 2G/EDGE.
Voice and data quality are very bad, almost the phone is unusable. I spoke with T-Mobile and was informed that my modem does not support 1700 MHz and there are effort to re-farm TMobile network to support 3G on 1900Mhz but not set date yet. When I scan for available network I get three networks were available
T-Mobile 2G
AT&T 3G
AT&T 2G
Operating System: Android 4.2.1 OS
Processor: 1.2GHz MTK MT6589 quad-core processor
Connectivity Technology: GSM network & WCDMA - Standard SIM card
Network Band: GSM 850/900/1800/1900 MHz & WCDMA 850/2100MHz
Data Technology: GPRS, EDGE, HSPA
Baseband version
MOlY.WR8.W1248.MD.WG.MP.V2.P1
I would appreciate any help to get my phone to work on 3G.
YAF, don't think it's possible to get UMI X2 to work with T-Mobile. You need UMTS support on AWS band.
Re-farming of network for 1900MHz support will not help you either - MT6589 only supports 850Mhz (AT&T band) and 2100Mhz(Europe).
Thanks CTPAHHIK
I got the Dual Xperia Z3 today, I have a number with Wind and number with Virgin mobile here in Canada.
I installed both nano sim cards in the device but it wont allow me to use both at the same time. If I turn on one, the other goes off, if I turn on the other one, the first one goes off.
The device tells me one can do data while the other does gsm only, both carriers use gsm, so whats up? why am I not allowed to use both cards at the same time?
I just want one for data (obviously), but I want to be able to send/receive messages and calls for both.
I s that not possible?
Just found this:
Apparently only Rogers or Fido (rogers is the worst at scamming their costumers) use those bands.
