I got this as a gift for my daughter and now all I get on TMO is 3G Edge. I am in Maryland, USA. I thought this thing was supposed to support a bunch of LTE bands but I don't see many matches for either TMO or AT&T. I've tried various APN settings to no avail. Someone suggested flashing a new modem to unlock the 1700 band but I cannot find anything on that either. Am I stuck with a 2G BRICK??????
Please help!

Stay close to WiFi! I'm afraid that you may have yourself a '2G brick'. It would appear that T-Mobile in the US use the following frequencies:
LTE Frequencies (FDD LTE, not TDD LTE)
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2 (in refarmed areas)
Lower 700 MHz band 12 (in development)
3G/4G Frequencies (WCDMA)
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2 (in refarmed areas)
2G Frequencies (GSM/GPRS/EDGE)
1900 MHz PCS band 2
The only band from this list that the M2 supports is 2G 1900 MHz. The 1700 MHz & 2100 MHz band is an upload/download pair and is different from the 2100 MHz band used in Europe (the one the M2 supports), which is actually a 1900/2100 up/down pair. I'm fairly sure that frequency support is a hardware thing, it's not possible to change supported bands by flashing a new radio module.
It's unfortunate for those of you in the US that Chinese phone manufacturers seem to favour the EU, rather than US, frequencies.
Thank you!!!!!

Thank you for your brilliant and most useful reply!!! Much appreciated! The M2 is now for sale up on Ebay and I just bought a Cube T8 Plus tablet that has phenomenal specs but it too has the wrong frequency support so I'm about to put that up on eBay as well. Thanks again!

I've just bought a AT&T HD7S off ebay from a US seller and I'm in the UK. It's not until just now that I considered how it might perform in the UK. I see that the AT&T HD7S lists HSDPA: 850/1900 MHz as its 3g frequencies, while the UK HD7 lists HSPA/WCDMA: 900/2100 MHz. Does this mean I won't be able to get 3g signal on UK networks? Does anybody have experience using a AT&T HD7S in the UK?
The HTC Help & How To page lists the following:
What bands does my device support?
GSM/GPRS/EDGE: 850/900/1800/1900 MHz
HSDPA/UMTS: 850/1900/1700(AWS)/1900/2100 MHz
But the Tech Specs page shows this:
UMTS: 1900/850
GSM/GPRS/AT&T: 850/900/1800/1900MHz
So I wonder if the phone actually supports 2100 MHz
And if so, since O2 HSDPA/3G in the UK runs on 900/2100 does this mean that the phone will still get 3G on 2100 MHz, but won't benefit from the 900 MHz band which enables coverage in harder to reach locations.
Secondly, should I only flash AT&T Radios on to this phone or can I flash the Europe modem found here forum.xda-developers.com/wiki/HTC_HD7/Radios ? Might doing so enable the 2100 MHz band which isn't used by AT&T ?

I got mine off ebay too (HD7S AT&T), did u manage to get the 3G working ? Please help me. Have you flashed the Euro radio ?
NO
UMTS: 1900/850
GSM/GPRS/AT&T: 850/900/1800/1900MHz
These are the correct specs.... because there's no 2100MHz band for GSM, the 2100MHz is used by CDMA networks.
can i flash my i9305 from german basebands to us basebands to be able to use 3g and 4g??
As far as i know, you can't change the band with changing the baseband. Your phone does support these frequencies:
GSM freq: 850 900 1800 1900 2100 MHz UMTS/HSPA+
LTE freq: 800 2600
Hey you might have to set the apn manually
Sent from a Galaxy far away!!
Does the d4 use both 2100 and 900mhz 3g bands (europe) ?
I'm thinking of importing one or the samsung relay 4g, but do both smartphones work at 900mhz (much stronger signial here) ?
up
Not sure about that, but I can confirm you that 3G works perfectly in Spain with this mobile
Here are the bands supported.
2G Network CDMA 800 / 1900
GSM 850 / 900 / 1800 / 1900
3G Network CDMA2000 1xEV-DO
HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 700 MHz Class 13
I have a Droid 4 in UK, and I can confirm HSDPA is working, but couldn't go higher than that, probably 4G is working only on 700 MHz, which no operator has in UK: hxxp://en.wikipedia.org/wiki/List_of_LTE_networks#Europe
Hey, I need help running 3G over 2100Mhz frequency on unlocked Tmobile D415, Ive tried using both these codes to enable 3G over 2100 and its not working:
3845#8415#
*#*#4636#*#*
I read some where that T mobile offers a rom for europe and asia where 2100MHz for 3G is enabled, any help please?
I am pretty sure the T-Mobile variant does not support the 2100 MHz band used in Europe. The supported frequencies are only 850 MHz, AWS (1700/2100 MHz), and 1900 MHz. The 2100 MHz used for AWS 3G is not the same frequency range used for 2100 MHz in Europe.
This phone was not designed with the international market in mind, considering it's cost.
Here is a more detailed explanation: http://www.phonescoop.com/articles/article.php?a=99&p=1493
The FCC wanted to harmonize its "new" AWS spectrum with Europe's UMTS 2100 band, since both would be used for new "3G" phone service. Unfortunately, as you can see above, the lower half of Europe's UMTS 2100 band almost completely overlaps with our PCS band, so complete harmonization wasn't an option.
However, given the circumstances, the FCC did do a pretty good job of harmonizing AWS with the rest of the world. The upper part does line up perfectly with Europe's UMTS 2100 band, and the lower part does line up with Europe's DCS band. Therefore manufacturers already building GSM+WCDMA "world phones" actually won't have to support any additional frequency bands at all.

This is a model made for US Cellular. Its GSM tho and unlocked.
Its super cheap right now and tempting.
Looks like it has 2, 4, and 12 LTE bands.
What I'm not sure about it the 3G bands (it has 1900 and 2100 but not 1700, would that cause a problem?) and 2G (in case im in the boondocks).
This one has:
LTE Bands 2/4/5/12/13/17/25, CDMA 800, 1900 MHz, WCDMA 850, 900, 1900, 2100 MHz, GSM 850/900/1800/1900 MHz
Anyone know more about this than me?
thanks
