No network access (can't make calls) after ROM change and sim unlock

I know for a fact that my original T Mobile USA HD2 phone worked, because I made a call to T Mobile support with T mobile sim card.
Then I unlocked the phone with cellunlock.net, tried my russian sim card - it worked. Then I got a message from my russian provider saying that roming feature was turned off, I couldn't make calls, I tohught it was a problem.
Then I installed Komar's ROM, and now it doesn't work at all! Not with T Mobile SIM card, not with AT&T, not with Megafon (Russia). There are no bars at all.
Others phones of the same providers work at the same areas.
What might be the problem?

I just performed hard reset with T-mobile sim card inside and this is what I see:
Multiple connection settings were found, please select one: T-Mobile, Tuyo Mobile

I select T mobile. Maybe that's the reason?

also remember go back to the rom thread and let those guys in that thread help u for ur rom even the cook himself may help

Never mind, there turned out to be a problem with my account. I have $0. Thanks anyway

[Q] no network coverage after installing wp7 on my hd2

just installed wp7 on my hd2 and after the start up my phone keeps searching for the network. have tried automatic network selection and tap to select but no luck. am using 2.15 radio. would appreciate any help.

goto your settings, scroll to cellular, then down to add apn, in the apn box type epc.tmobile.com and leave the rest blank.
this works with tmobile us

isn't that supposed to be only for the data connection? even without entering the apn the phone should be able to find the network for just making voice calls. so mine seems to be a different problem. the phone is simply unable to catch any signals.

from my understanding of the whole cell phone fiasco is the sim card has everything the phone needs to connect your providers tower and also tells your phone what services you have voice, data, etc etc, so it should setup voice automatically. i would try searching for the program (htc connection setup) they use to install the xml files it also sets your phone with the provider.
good luck.

Only search at the internet for your apn settings, enter them and voila you can use your data connection, nothing more nothing less and done in a minute. HTC Connection Setup don't work well but you have to use it later if you want to change phone type to HD7 for the Marketplace ^^)

yeah we covered that part, the concern is that the phone is/was not connecting to the towers

Maybe check out other Radio ROM. 2.15 should work well, but uses more battery.

switched back to winmo 6.5 for a while and the same radio worked fine (caught the signal etc.). Just now again tried to flash wp7 using 2 different radios, that is 2.12 and 2.14. Have already tried 2.15 with my first attempt, but the problem just remains the same.... 'no network found'. any thoughts? have even tried putting in the apn too. no luck

u know its funny cus its the exact same with mine exactley the same ive tried everything and it picks up the signals but it wont let me connect to any network at all... the phone is just fine except that one problem.. plz any body help us with this stupid problem

i was havin the same damn problem, and i just flashed the 2.11.50.26 radio, and boom baby!! instant network connection. no more 3 beeps and disconnection for me now to check battery life and wifi (no 3g in trinidad yet, so u can't test that)

sim lock...???
After trying different radios by flashing and re-flashing, I've noticed something I should mention. My phone dialer shows a sim icon with a lock on the top left of the screen. Does that shed a new light on things?

sim lock ???
hey sameer... I have the very same issue with my HTC HD2. It is unlocked and I am facing the very same issue that you are when I revert to WinMo 6.5 everything works fine with the same radio. I've tried almost every radio now and have no luck. However, the funny thing is that I do see the sim with a lock when I go to my dialer. I suspect the OS is SIM Locked, however, when in WinMo 6.5 every Sim Card is recognized and works properly
Any luck with the issue yet??
Let me know of your thoughts... btw I'm on Ufone's Network.

It's the sim card!
Problem solved for me and hopefully for salmanjavaid too!
I learnt it the harder way though, by which I mean that I spent money to buy an HD7 and after inserting my sim in my brand new HD7..... no signal again! oooops! Only then it occurred to me to try some other sim cards. My network is also Ufone here in Pakistan. So first I tried a Prepaid Ufone sim (the one with white and orange colour and 64K printed on the back)...and Lo and Behold my hd7 gets the signal and network settings and data connection works fine too! Other operators' sim cards like Telenor, Warid and Mobilink worked fine too. But when I insert the sim card which is in my use back again....no signals again! This sim card is a different version, perhaps not 64K and plain black color on the back.
A call to my Personal Customer Service Executive assigned by Ufone sets the next course of action. He'll bring a replacement sim card for me, when I get back home.
My suggestion to salmanjavaid: try other sim cards first. If they work then get a replacement sim card.
Hope it solves your problem too.

id give this a shot. I'm on vacations in Pakistan and have my Sim Card from O2. I will give it a shot tonight Thanks for the suggestion.

That just means the sim card is not a Verizon sim card, but as you know its unlocked so it still works, but as far as I know their is no way to make it go away.

Thanks for the answer still wierd to have this

slow internet speed in my phone

Yes. just in my phone and to only one sim card. When I put the sim in my friend's mobile the speed is normal.
possible reasons: Before some day I went to my village and the network reception there is very bad. I couldn't open any pages(pretty slow) .Now I am back to my previous place but the speed is same. I dont have 3G network here.
I have GT-S7562 rooted(dual sim). the problem is only with one sim card and only on my handset. I tried with new GPRS settings, rebooting, flight mode,network searching, interchanging simcards... not of any help. Its been 15 days since.
So what could have gone wrong? help

do u have a data limit?

What do you mean only one sim card? If you put another simcard (ex a friend's sim) does the phone work correctly?
If thats true then you should try getting a new sim card from your provider.

Keep in mind that your data speed has many limiting factors. (Ex. Service strength/ the cell phones actual capability /geographical location or region) but depending on your service provider, it's realitivaly cheap for a new SIM card in many cases. Last time I needed a new one it was $15...

Did you try another sim in YOUR (not a friend of yours) phone? It might be the phone's fault.

thank u all. As I said the problem seems only with that only sim.. other sim cards are working fine on my phone. Anyway I dumped that sim & got a new one.. All works good now. Don't know what was the problem with that SIM card. even Tech staffs couldn't solve it.

Go to settings>>more netowrks>>mobile networks>>network operators..let it search then choose Telus, if it works you should see a message "registered on network" watch for it because it disappears after a few seconds.
The other thing you should check is that the network is actually up, not sure which part of the country you are in but you might want to check the Telus site to make sure they aren't just having network issues.... happened in Calgary a few months ago....
Also check network mode in settings should be set to lte/wcdma/gsm lol I set mine to GSM only and nothing worked....

Just a silly question but did the sim click into place or can it just slide ot? When it is properly in place, you should have to push it in to eject it.

So having further checked into the phone, the IMEI is blacklisted and reported lost or stolen.... That's why it worked at first and now does not!
Be careful buying used phones off Craigslist or anywhere I learned the hard way thank you for your time! :/
