Unlocked tmous won't connect with tmobile sim - HD2 General

Hi I have been using my htc hd2 for over a year, I unlocked it in the begginning and have been using ATT on it til now. I have recently switched over to tmobiles network but for some reason my htc hd2 won't connect with the tmobile sim card now. I am running an andriod nand.

Does the phone still work with the ATT sim? if so its not the sim card carrier/reader on the phone
Where how did you unlock it?
Just changing to Android does not unlock it, normaly its a cost to you to buy the code £15 to £20 in the UK
So if you only added Android its not unlocked

I'm sure its unlock. As it is branded as a tmobile phone and I purchased an unlock code for it awhile back and I entered it while I was on windows 6.5 and it allowed me to use the ATT sim card til now when I switch back to tmobile it won't let me. My att sim card still works with the phone just not the tmobile

Sound like one the sim:
Does the Tmobile sim, does it work in a different cell?
Does a different sim work in the phone (not including the ATT sim)

I'm pretty sure its not the sim card, I've tried multiple sim cards from friends and the ones from ATT works but for some reason the tmobiles ones don't work I have no clue. Strangest thing too is that I flashed stock windows mobile 6.5 and a new radio rom and the phone connected to the network and i was able to make a call but 2 minutes later "no service" again....
Its only the tmobile sim card too.

HTC HD2 network problem

I've got an HTC HD2 Virgin branded from Ebay, It said that it is unlocked. Tried it on T-mobile, O2 and Vodafone.
Only worked on T-Mobile.
When I put O2 or Vodafone sim card, it can't even connect to the network.
Is my device locked??? Or is it faulty? Please help
sounds like its still network locked to me. virgin piggy back on the tmo network I believe, maybe that's why tmo works?
(just thinking out loud)
but the phone didn't ask for unlock code even when i put different sim card?

Sim Problems

Hi, ive just got an hd2 locked to t-mobile UK and when i put the sim in it dosent pick up and signal, also i have tried it in my htc elf and that dosent pick any think up! please help.
Now am I getting this right?
The sim is not working in 2 different phones, correct?
If so - then are the sims compatable? (unlocked phones or the same sim as brand, ie orange phones and orange sim)
If so replace the sim if not - then think about it a bit

[Q] Calls Work with one SIM and not the other

Having a problem with a Telstra HD2 model.
With a Telstra SIM in the phone, I can make and receive calls. When I insert a Vodafone SIM into it, I cannot make or receive calls. Call hangs up straight away.
Device is not network locked as HTC phones are not locked with Telstra. Bars display in task bar.
Tried it with Windows 6.5 (factory default) and Android custom ROM. Currently on custom ROM.
Any thoughts?
I had a similiar problem a few years ago and all i had to do was get a new sim card. I was told i had damaged my sim card some how but i was able to save the contacts, transfer them over to the new sim T-mobile gave me and I have not had another problem since.
If you have access to another phone try and insert both sim cards you have in the other phone. If you have problems in the other phone with the sim card thats not working you can safely say its the sim card thats not working correctly and not a phone issue.
Thanks for the reply Craze.
My SIM's do work as I use my Telstra SIM (that works in the HD2) in my old Nokia and my Vodafone on my Galaxy Nexus Prime.
So on the HD2, my Telstra SIM works where I'm able to receive and make calls and my Vodafone is the opposite.
Could it be the phone? I'm hoping that it is so that I can fix it.
Could it be the network providers? If so, then I'll call them which I've already done but they couldn't give me an answer as to why my Voda SIM does that in the HD2.
