Hi , I have Htc hd2 t-mobile and i sent it to the company to unlock , when i tried to use vodafone sim card it worked but the 3g service didn't work anyone could help me please really it will be very useful .
Different 3g bands? What country you in?
Egypt and i bought it from USA
I do not know what bands/frequencies your carrier uses but you more than likely will not get 3G on your HD2. You see the T-Mobile HD2 is branded to T-Mobiles 3G bands/frequencies for 3G. This is done by the hardware in the phone, so no ROM or app will allow you to get 3G if your carrier does not use the same bands/frequencies. The best you will get is Edge on your HD2.
Tmous the network uses AWS meaning it uses both the 1700 and 2100 channel, one for upload one for download. Most other networks use one for up and down.
Hey Guys,
I am situated in Germany and in my opinion, the ATT Versions of the S2 is the most beautiful one. My carrier ist o2.
Is it possible to buy a S2 ATT via the US Ebay and use the phone without any restrictions in Germany?
I guess I need to root it first, then unlock it and then I am good to go? Are these thins easily and safely to achieve? Is it that simple? What about the network, is the american version compatible with the german network? Can I use hsdpa?
Any other restrictions?
Thank you in advance.
the usual problems with US phones in europe... no 3g, but if your only there short term, it may be worth picking up, otherwise just get the euro version with the correct bands.
also i havent checked but there may be a quad band umts unlocked
AT&T version only has tri-band (850/1900/2100) HSPA+ radio. So if your carrier O2 uses 900 band for 3G service, your phone will only work in 2G mode.
International version of GS2 has quad-band HSPA+ and it works everywhere.
I just flashed my rogers lumia 920 using navifirm with the .1002 ROM because .1001 was not there. Well, phone is working fine, BUT...this new firmware disables AWS 1700!!! My Wind SIM is only connecting in AWAY mode, and when I insert a Rogers SIM, and select manual network selection, both Wind and Mobilicity have disappeared! Only Fido, Rogers, and Bell are showing!! Radio version and everything else is the same! Does this mean Rogers crippled the firmware?!

Probably something else. Their website list support for AWS band, not unlike AT&T which Nokia did not list any AWS at all. Just a curious, did you have your phone unlocked or still lock? Try to determine if it still using AWS when you put your Wind sim into it by following this

I doubt it as I am running .1002 and I can see WIND and Mobilicity in the network list. I haven't tried to connect to WIND as I dont have SIM card for them.

Phone is still unlocked..and wind sim is only connecting in Away mode. It's not even connecting to 3g. When performing a manual network scan, it shows three networks, all titled (Wind Away).
I had flashed an AT&T ROM a few days ago for kicks, and reflashed the rogers one. Could flashing the AT&T rom have permanently disabled the radio for AWS?

That maybe the trigger. Sometime flashing another rom over another will leave some files behind.

Anyone know how I can view the files and delete the one that triggered disabling the radio?
Try doing a hard reset. I know with the old WM phones the rom cookers would ask you do a hard reset after flashing. Or try flashing again.

Tried all of that. I cannot believe how much AT&T crippled the firmware! Even the radio version, firmware, everything is the same as on my other Lumia 920, the one which I mistakenly flashed an AT&T rom and back to Rogers ROM has lost AWS 1700

AT&T. Rethinking possible ways to screw everyone. Even if you bought your phone somewhere else.
flashing ATT firmware on Rogers Lumia 920 WON'T disable AWS1700. i do have a Rogers Lumia using on T-Mobile/ATT and flashed an ATT ROM and i still get AWS1700 on T-Mobile. i have SG Note2 on TMo and verified that my area only uses AWS1700 on 4G not the refarm 1900. my wife's iphone 5 only gets EDGE on T-mobile when i put my TMo SIM in, so refarm 1900 does not work on my area.
maybe reflash it with Rogers .1001 and then .1002 after.

Where can I find Rogers .1001? I have it on my other phone, but cannot find it on navifirm. My other Lumia is just fine, but this one screwed up after the flash, and I don't see any AWS 1700 network at all.
I'll just copy what I wrote on WPCentral over here:
"I have a Dev 920 which worked on AWS 1700. Then it was flashed to AT&T which disabled the AWS 1700. Then it was flashed to Rogers which you'd think would bring back the AWS 1700 but it did not. I cannot flash it back to Dev firmware because Nokia doesn't have it available.
It seems AT&T firmware cripples the AWS 1700 permanently somehow. And the Dev phones are RM-820 which are North American phones."
Although I also flashed to .1002 since that's what's in the Nokia database. Someone find me the .1001 Rogers and I'll test it out.
I have similar experience on this. When I flashed Lumia 710 (US TMO version) after sending a wrong update (yes, I've bricked it by sending wrong firmware), I've recovered it by uploading Rogers' image. That worked fine. I then revered it back to TMO image. The device, 710, works great and everything. It even has TMO boot screen and applications. However, my setting/about screen still says "Carrier: Rogers CA SW variant ID226 v.01".
Perhaps there's something that stays behind even after FW flash.
To enable AWS
Try flashing RM-821 VAR EURO1 DEVELOPER firmware on your device. I was skeptical flashing RM-821 firmware on RM-820 but it enabled AWS. My developer device is back to running on HSPA on T Mobile ! (http://forum.xda-developers.com/showthread.php?t=2097815&page=4)
Hey.
Please tell me if Galaxy Alpha G850f will work normally in the USA?
All I know is that there are different frequencies in the USA and Europe. Do my european model G850F support both of it?
From the spec I saw, you may get 3G on AT&T. Not so much on T-Mobile because the lack of 1700MHz band support that is still in use by T-Mobile 3G in many places. The LTE bands are probably not going to work. Of course, CDMA carriers like Verizon and Sprint will never work. So, you are guaranteed to have 2G data (which is like dial-up modem speed) if you choose a GSM carrier. Everything else depends.
I had 85of on att it is very fast hspa plus. No lte
Hi need help please , I have a Galaxy S4 I545 , I can anly connect on 3G and even in the back of the device says s4 verizon 4g lte . When I change the LTE network goes without service. Let alone globally connect on 3G, I wonder if I can enable or install 4G LTE bands . Thank you
The SCH-I545 should have 4G enabled automatically. 4G is already installed on the phone unless it has been messed with (ROM,kernel etc.). Is it possible you are just not in a 4G area or have it on your Sim?
Are you located in the States?
The phone is 4G capable, only in USA. Outside, its only 3G. That is how Verizon did it, locking bands so Verizon users cannot have LTE with other providers like T-Mobile or Sprint or ATT. T-Mobile should work worldwide. For Verizon, you will need to unlock bands.
What country are you in ? Most probably, you need band 3 or band 28 which are deactivated.
I'm from Morocco
