Hi to everyone!
I wonder whether it's possible in any way to activate such LTE frequencies in our phone as 800, 1800 and 2600 MHz that are commonly used in Europe?
As I understand the phone supports every of them but the frequencies except ATT's 700 and 1700 MHz are not active, e.d. blocked.
Am I right?
So, is there a solution?

I purchased a jailbroken AT&T Tilt 2 online but Im using T Mobile service and I was told that I wouldn't be able to access the T Mobile 3g Network with this device. Could someone verify that this true or if not can someone give me some tips on how to set it up on my device.
Its true, because I have a Tilt 2 unlocked to T-Mobile as well. Is there a way to get 3G speeds, I don't know. But honestly, I've never really noticed a difference. But then again, I do stay away from data heavy sites like Youtube and whatnot.
Hmm, interesting question. The main issue is whether the phone has the right bands to connect to the 3G network in question. Its a hardware issue, and either the phone has the right bands built into the chipset or it doesn't. There is no way to change this with software or by changing settings.
T-Mob uses 1700 and 2100 MHz bands, where ATT uses 850 and 1900 MHz bands. HOWEVER, the ATT branded Tilt 2 also has the 2100 MHz band for international use. If your T-Mob service area is on the 2100 MHz bands, its possible (if you area is on 1700 MHz, its not going to work no matter what). In theory, it SHOULD work. I've made many trips to Japan, which uses 2100 MHZ for both voice and data, and my Tilt 2 (and old Tilt before it) has always worked flawlessly on their networks.
But whether it really works or not, I have no idea. Searching around the net yields some posts on other forums asking the same exact question, with conflicting answers (perhaps somebody on here can enlighten?). My gut says, its either its going to work or its not, it shouldn't take any additional setup. Have you tried it yet?
But in short, it was a mistake to buy the ATT branded version. You should have bought the T-Mob branded Touch Pro 2.
Oh, and wrong subforum, BTW. This has nothing to do with ROM development. This should be in the Touch Pro 2, Tilt 2 General forum. But don't cross post there, the mods will probably move this thread over there for you.

The 2100 MHz band you're referring to is different on both companies' devices. For T-Mobile, 2100MHz is the upload frequency. The worldphone AT&T 2100MHz band is a download frequency. 3G requires 2 frequencies to operate in that manner.
The 2100MHz frequency is accompanied by the 1900MHz frequency for uploads. The AT&T Tilt2 has this frequency set to allow both.
As for Japan, I didn't know they were on the 2100MHz band. I've only every seen a couple of companies on 850, 1500, or 1700 MHz. Where were you that you used 2100MHz or which company? I just like to keep up on where the bands are useful when I make trips to Asia.
Ahh, that's right, I think I did read somewhere, that the 1700/2100 MHz bands are used by T-Mob as download/upload. Not like ATT, where which of the 850,1900 MHz band is used for 3G depends on the geographic location/market.
That means the OP is SOL on getting 3G on the Tilt2, right? He would need BOTH the 1700 and 2100 MHz bands on his phone?
Japan uses 2100 MHz exclusively, standardized nationwide, as far as I know. Same with South Korea (although ATT lists that one carrier in S. Korea also uses CDMA 1800, not sure what the deal with that is).
If the 2100 MHz band on the ATT Tilt 2 is just for download, wouldn't this mean that my phone would not be able to connect to the data network in Japan?

Exactly right. It's a hardware problem, not software as some people think. I seem to answer this question at least once a week here. lol The radio chip is different for each model of the Rhodium. That's one of the differences between the several versions.

It depends on what the network is set up as. 3G worldwide requires two bands to operate because of the bandwidth. GPRS and EDGE only require one. If this 2100 MHz frequency is one of the later, then it will work just fine. If this is a 3G band, then it is VERY likely to be paired with the 1900MHz frequency range. That's on GSM, anyway. I'm not 100% sure what CDMA frequencies are their.
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.
900 and the 1700 MHHello, this is my first post, an uncle gift to me a droid 3, i already root it and do a lot of things, is a great phone, but in my country, my network use the 900 MHz band to 3g connection, obviustly my phone is from the US, from verizon, so my phone got the US bands (850/1900/2100) as you should know, so, i was believing if there is some way to change a band to use 900 instead of, for example 850, my local network use the 900 and the 1700 mhz bands, i don't know if that bands are hardware or software, but if there is any possibility i really will thanks any help of answer
Pd: and of course i'm making this thread because my phone just take up to E, i know that is capeable to reach H, but i don't want to change my network provider
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.

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!
