[Q] Unlocked T-Mobile phone wont connect to AT&T - General Questions and Answers

I recently got an HD2. According to the seller it is unlocked, but With my AT&T SIM card in it, it won't connect to the network. Originally it had WM6.5 but I have also tried it with ICS and GingerBread and it does the same thing. The closest I have gotten is a message that says "Registering on AT&T..." then after that it says it failed. Help? I know 3G wont work, right now I'm just trying to get phone and SMS working.

If anyone has some input it would be really appreciated. :good:

Please help

T-mobile Mda Compact (magician Pm10a)

Hi everyone,
I love this site, and it has been very helpful with all the information.
I'm stuck in a dilemma at the moment.
I had managed to un-lock my T-mobile MDA Compact. and had been using it on O2 for more than 2 years.
Just the other day,it came up with a message saying "No Service", where it shows the network coverage.
I tried my T-mobile sim card, and that works fine.
I tried the O2 Sim in my mates phone, and thats working fine too.
I tried an Orange Sim in the MDA, and still no coverage.
Could it be that it has managed to SIM-Lock itself again?
I have downloaded the un-locking program again, and tried to un-lock it. It comes up with a message saying "phone un-locked", but still doesn't work with my O2 sim.
I need help to make it work again on O2.
Any information on this will be most appreciated.
Thanks again guys, and keep up the good work.
Cheers,
Jas
Looks like something is wrong with your simcard rather than your phone
Hi Moos,
I have tried the SIM in an un-locked Nokia, and it works perfectly.
I have dropped myself in more problems :-((
I downloaded the ROM update program from xda-developers, and tried to flash it.
It got to 3% and came up with an error message.
After that, the phone says "NO GSM" when you start it up, and won't recognize any sim at all.
I tried to update it with t-mobile's ROM from their site, and now it keeps coming up with a COUNTRY ID ERROR.
I love this phone and don't want to throw it away.
I know there's someone out there that can help me out.
Please, anyone, if you have any info, and any software I can use to flash it, help meeee!
Thanks in advance,
Jas

After spending time on the site last night, I figured out a way of flashing my ROM with the current software.
I managed to do this, and now I'm back at square 1. My phone will recognize a t-mobile SIM, but will not recognize any other SIM cards.
I have ran both versions of xdadev_all_unlock, and they both come up with a message saying that the phone has been unlocked.
But still, no joy with any other SIM cards.
I have also noticed that the IMEI number shown under phone identity is different to the number printed at the back.
As mentioned, I have been using this phone (after un-locking it on xda-developers) for more than 3 years. It has never given me any problems until now.
I contacted T-moble about this IMEI number, and they said that its the number printed on the phone that matters. DOn't worry about the number shown on the screen.
Is this true?
Please please help me out on this one.
Thanks,
Jas

No network in US but works fine in Canada

Hi guys,
I'm new to the forum. I've tried searching for some answers but can't seem to find how to resolve the problem. I'm quite new to using PPCs so let me know if there's any information that you guys need.
So my phone works fine in Canada using Rogers... but everytime I go to US, I cannot detect a network for my phone and there's a "!" at the top. I tried searching for a network and it says "no network found" or sometimes it tries to register and then it fails in the end. In US, my phone automatically shuts off... I have no idea how this happens but everytime I go to look at my phone after leaving Canada, it's off. So when I go to turn it back on, there's no phone signal. I have no idea what to do as I'm not very familiar with PPCs.
Thanks for the help!
Which phone are you trying to use? Guessing Touch Pro?
Is international roaming or data roaming added to your account with Rogers?
Hey I have the HTC Touch Pro... yeah I've used this sim with my eten m700 before and it works fine. It just always seem to be searching for a network then it can't find any.
Thanks!!!
are you a prepaid customer? if so, Rogers doesnt allow roaming outside of canada.
Hey there... Just figured I'd pipe in here...
I am still using a TyTN (shopping for a Touch Pro today), and although I was able to always use my phone in the states, since my last firmware upgrade (WM6.1, new radio stack)....
....I can't get any service when I cross the border.
SOMETIMES I'll get 10 minutes of service over the course of an entire day. Very strange.
It is obviously firmware-related... Good luck with your phone...!
Thanks for all the help guys...
Nope I'm not a prepaid customer... should I be upgrading something on my phone to see if it works? Sorry... really don't know much about PPCs here!
just out of curiousty, have you called Rogers to ask for an updated OTA to be pushed to your SIM?
I've contacted Rogers and they said it has nothing to do with them... it's my phone! Should I contact them for the OTA? I'm sorry to be so noobie but... what does OTA do?
Thanks again!
Anyone help please!!!

[Q] Nexus S Wind Mobile help!

I just bought a Nexus S off of someone, who assured me it works with windmobile (in Canada). I pop in my sim card, and it shows 302490 (Wind tower) but whenever I click on it, it'll always say unable to connect at this time.
I did a full factory reset, and multiple reboots, and multiple sim cards (all wind).
Btw, it has an unlocked padlock on the bootup screen, but the person I bought it off of says its never been rooted. Don't know what to make of that.
Someone please help!
I think the unlocked padlock means the bootloader is unlocked. I was having a similar problem to you. Try this link out. It helped me.

Have you changed the network setting for Wind Mobile.
Sent from my Sexy Nexus S, eh?
if it says I9020T on the back under the battery then it is compatible if it says I9020A then its not compatible, simple as that
