NO Phone/GSM on my T-Mobile MDA II - Upgrading, Modifying and Unlocking

Hi guys can anyone help!
I have a himalaya MDA II on t-mobile. It has the lastest O2 uk rom and operator has been set to T-mobile.
I can connect with GPRS, I can send sms messages, I CAN'T PHONE IN?OUT!!!
When i try dialing in i get - "Sorry there is a fault" voice message. When i try dialing out i get three short beeps, and the message 2call ended on the phone.
I have tried 3 sim cards, Tmobile(current and new) vodaphone( working , on my works phone), and O2 (my girl friends) all have the same problem-henc3- logic suggests the phone.
I wondered if the IMIE number had been blocked, but surly all the other services would not have worked.
Please any ideas? :evil:

Successfully unlocked O2 XDA II but can't make/receive calls

Hi,
I've tried both the 1.5 and 1.6 unlockers and both report success. I have fitted a Vodafone sim and both the sim and network are recognised.
However, if I try making a call the screen shows 'Dialing..' then goes straight to 'Call ended'. If I try phoning the Vodafone number then it is reported as unable to connect. I have tried both soft and hard reset.
The Vodafone sim is valid and works fine in another phone (I no longer have the original O2 sim , it was on a company contract that has been cancelled).
Do I need to set anything to use the Vodafone network or any ideas on gettting this running as a phone again?
Thanks.
Just noticed that under Phone Settings it says Phone Number: Not Available...?

Yep, hard reset at least 3 times now. I've also used the PIN to lock and unlock the SIM so the XDA and SIM are talking.

Hi I have an o2 xda orbit .I have put a t mobile sim in and it phones and voice mails fine,but i cant access the net with it ,any thoughts please!!
you need GPRS and the correct settings. Prvide more info.
hi its connecting to gprs ,the answering modem is disconecting-thks
Do you know, it cost you nothing to type more in your post? However, it does cost you 'the answer' you are looking for if you type less.
Ok a few questions.
What country are you in now?
Does your phone cames from t-mobile?
Is the phone using t-mobile (your country) ROM?
Did you skip the Ext ROM installation?
Have you manage to connect to Internet before?
Does your telco package include Internet?
What do you mean by 'answering modem is disconnecting'?
p/s: If you find me not trying to help you further, either I don't have 'the answer', or I just fed up asking Have a nice day.
hi yea sorry to miff you with the lack of info I will try to address that this time
country UK
Phone is made by O2 (mda Orbit )I am using a t mobile sim that can access the web in my motorola 3i razor ( definate yes to the do I have internet package)
I did install all the disks that came with it (O2)
This phone in new out the box and has as yet to be connected to the web
When i try to access the web I get the message
when i try to get on to explorer i get the message "connecting to gprs",theni get the error message "the answering modem has disconected."-thks
I'm not sure, probably the O2 phone is trying to connect to the O2 GPRS instead of T-mobile, hence the problem. Anyway, read this
http://www.4winmobile.com/q-what-are-the-uk-amp-roi-gprs-settings-for-web-wap-mms-vt1834.html
on the sectin "Setting up Mobile Web connections", it has the settings, and rather detail instructions on how to set up t-mobile UK. Hope that tmobile still uses the same settings. If not, try the WAP section.

HELP!!! - hw6920 - IMEI not found

Hello, I am new here...
Help!!!,
I've bought a Cingular hw6920 and I would like to use it when I travel, with local SIM cards.
The phone is obviously locked and when I try to use another SIM, it shows the message "Network is locked, please input unlock code".
Since I have a Cingular account, I've asked for the code, but after sending them the IMEI (correct), they have replied that they cannot find it!
Same thing happened when I've tried to get the code through one of the pay services.
Any suggestion? I can't return or exchange the phone since I left it to my brother in Europe.
The phone has never been turned on in the US with a Cingular SIM, could this be the problem?
Thanks

Question Calls do not work when roaming

Setup:
sim: O2 - UK
e-sim: Orange - PL
I'm currently in Poland
Everything has been working fine until some 3 days ago. Since then:
O2 UK is showing as fully properly connected to a local network (roaming)
I can receive and send text messages via O2 UK (roaming)
Nobody can call me on my O2 UK number
I cannot make calls using the O2 UK number (I'm getting "the service you are trying to use is not available for this number" - in Polish and English, so presumably from the Polish roaming operator)
The O2 UK simcard has no issues in my old Oneplus mobile phone (it does take some 10min to work fully), so I know that roaming works. O2 have also confirmed that the roaming is unrestricted for me and they see no issues on their side.
I have tried manually selecting the network with little success (it keeps disconnecting and then switching back to automated selection).
Any ideas or similar experiences? :-/
Try forcing it to use hspa network, disable volte, etc.
