3g in argentina please help!

hi, i have a brand new rhodium t-mobile version, flashed with the nrg rom feb 1st.
when i use the data connection the phone connects to the edge network, while the same sim card connects to 3g/H on a motorola milestone. i read on google that 2 or 3 users (the phone isn't sell in argentina) that have the same problem...
the 3g network in argentina works in the 1900/850 band, so i have it configured that way but it doesn't work.
does anyone knows how to solve this, please?
thanks in advance

3G with the T-Mobile version (RHOD210) works on the 1700/2100 MHz AWS spectrum. You will not be able to use 3G on your network with this device. There is no fix or work around. This is a hardware limitation.
EDIT: You should have gotten the Tilt2 (RHOD300). This is the AT&T branded version that has radio hardware which supports your network.

ok, last question, why in the band section it has the option to use 1900/850 Mhz?

that´s what i thought that it would work..

If it truly does support switching bands, as the link you posted would indicate:
http://support.t-mobile.com/doc/tm5...5611&navtypeid=6&pagetypeid=7&prevPageIndex=5
Then, I would recommend flashing the Stock ROM. Then see if you can get it to work with the stock T-Mobile ROM. If you can, then it probably is possible to do it using an Energy ROM as well. But, I don't think it is possible.
I am not that familiar with T-Mobile phones, since I use an AT&T Tilt 2. It seems unlikely that this would work, since in the United States even the T-Mobile HD2 doesn't get 3G when SIM unlocked and switched to use the AT&T network with an AT&T SIM.

That band switching feature is to set network preferences for your carrier outside of the US. The radio hardware does not support UMTS 3G. You will only be able to get EDGE speeds at best from this device on your carrier. You need the RHOD300 (Tilt2) to get 3G on your network.

that´s a bummer
thanks for your answers

You can use an SIM Unlocked device on any GSM carrier. The main issue is you have to check the frequencies it uses for 3G. They may not work on your provider & therefore you won't get 3G.
AT&T Samsung Focus 3G frequencies as per GSMArena are;
"3G Network HSDPA 850 / 1900 / 2100"

[Q] Unable to use UMTS Mode (ONLY GSM WORKS )

Hi all
I just recently acquired a INC 2 Love the phone by the way and am located in INDIA
I'm running a r1 rom which offers full GSM functionality
SIM: TATA DOCOMO
The issue I have is
I can connect to GSM only Mode , but when I try GSM/UMTS or UMTS Only , the phone cannot cannect to a network.
The phone is SIM unlocked and in GSM only mode I can call/sms/data fine
My service provider uses the 2100 mhz band so obviously the INC 2 supports that, I have searched and lot and have tried various ROMS, but unable to narrow down a solution
i have tried the *#*#4636#*#* mode and even there only GSM ONLY works
NO GSM/UMTS , WCDMA or anything
Basically I cannot connect to 3G
Any suggestion guys

bump guys...... 98 views and not a soul to reply

Had the same problem, couldn't find a solution. Bump!

Have you try manually entering the APN (access point network) for your carrier? That might help.

Yes I have, pretty much tried everything.

yes the APN is the same for both GSM and 3G
It just wont connect to a 3G network... only works on force 2G ie GSM

That is kind of weird. Does Tata only uses 2100 mhz? Maybe try updating the radios? Does the stock rom also not picking up 3G?
I'll be traveling to Hong Kong in 2 weeks and there uses 2100 as well. Let me see if I can get 3G and will let you know. It's hard for me to test UMTS on my DINC2 here in US coz I could only get EDGE from TMobile or AT&T.

All Indian networks use 2100 ... Yes it did not work on stock either ... I'm wondering if band unlocking is needed ..

[Q] Unlocked Desire HD won't find network/get signal

Hi all,
I was hoping someone could help me with a problem I've had with my HTC Desire HD. I've unlocked the phone (but not rooted) having moved from the UK to Canada and wishing to use a Canadian sim card in my phone.
However, I don't get any signal or any network with my Canadian (Virgin) sim card. It accepts the sim card and allows me to use the phone, but I get no signal whatsoever. I've tried taking the battery out and waiting 30 minutes, and have gone off and onto airplane mode to attempt to get it to connect to a network, but nothing.
Is this something that rooting the phone could help with? Is the fact that I'm in a different country anything to do with it? The only network it can even find is called 'EXT' but it won't connect. Anyone able to help?
Some extra info:
Model Number: HTC Desire HD a9191
Android Version: 2.3.5
HTC Sence Version: 3.0
Software Number: 3.13.61.5
Any help would be so greatly appreciated.

I'm going to cover the obvious first, you put the sim cover back on right? Its needed for the antenna

Yeah, the cover is back on.
The other strange thing, is that the phone recognizes a Canadian number in the Phone Identity.
I've tried a different Canadian sim card, and that works. The sim card that is not getting signal works in other phones too.
It's all a bit odd.

Sounds like its the sim card is the issue. I had a similar encounter a while back, my sisters tmo sim wouldn't work but my brothers tmo would. So it could be just needing a new sim or the carrier might have some kind of lock on their Sims. Just because a phone is sim unlocked d doesn't guarantee any sum will work its kind of a trial and error sometimes

Thanks mate. Perhaps I'll take it down to where I got the sim card, see if they're able to help me out or not.

Desire HD from UK will not work at all in Virgin Mobile Canada.
VM Canada as being a virtual operator uses the Bell Mobility Network.
Bell Mobility works in LTE band and 3G but 850 MHz and 3G 1900 MHz.
Desire HD does not have those bands in 3G (only 900 and 2100 MHz).
Desire HD has 850 MHz and 1900 MHz band but only for GSM 2G. But Bell Mobility does not have GSM network. Only 3G and LTE.
Here is the list of the mobile operators in Canada. You can use SIM card from any operator which has GSM 850, 900 or 1900 MHz or 3G 900, or 2100 MHz.
http://maps.mobileworldlive.com/network.php?cid=88&cname=Canada
(but please check if any of those compatible operators have any coverage in your area. From the network you found it seems that Execulink Telecom has the coverage but it will be only 2G).
You may see people using there Desire HD in VM network, but if you take a closer look, this is actually HTC Inspire 4G which is basically Desire HD but for the North American market with LTE and different band radio modules.

Hmm learn something new everyday. Didn't know virgin didn't have an 2g network, that explains the op issue

To be completely honest, Bell Mobility has a 2G network, but it's CDMA (also with Ev-DO) so completely another story, not related to Desire HD or Inspire 4G

Not enough info. Need the phone's CID, and what 3G (UMTS) bands used by your carrier.

I Google and found this CID for my phone spcs_001. I got to know this from terminal emulator. Sorry but I don't know what band is used by my carrier.but I recently took 4g sim from my carrier which is working great on my brothers phone but not on my phone。I am using Airtel's 4g SIM and not able to use even 3g on it .

Thanks, I have called my carrier and they advised that 2100 for UMTS (3G) and 2300 LTE (4g) band is used by Airtel.

You have the Sprint version of the phone (based on CID) which should be compatible with 2100 MHz (UMTS). This phone does not support 2300 LTE, but you may already be aware of that.
Are you sure your carrier's APN info is entered correctly?
You sure 3G worked for a week? Any changes that happened that could have have changed that?

Thanks for sharing this detail, I was not aware about the 4g which you mentioned. Yes my APN is correct and i have crossed checked with my carrier as well. And yes i have used 3g for a week and after that I took another SIM from my carrier(Airtel) 4g sim and just after that my 3g stopped working.
And I have checked my new sim in another phone so it's working fantastic but not in my phone. and I have checked my brother SIM in my phone so even that sim's 3g is not working on my phone. I could not understand all of sudden what went wrong which it stopped working.

Check the APN again, and that is the currently selected, active APN. All I can think, is that inserting another SIM changed the APN.

I checked again, but still same issue. What should I do any suggestion. Or could this be a software or hardware issue how to know this. Any idea
