Using a 'network locked sim' ? - Upgrading, Modifying and Unlocking

Hi, I have spent nearly a whole day searching for an answer to this...
After having been wowed by wm6.1 on my tornado (thanks to all the work done on this site), I have made the big mistake of getting a contract with Three (UK 3G provider), who it seems lock their sims to work only on phones provided by them.
Is there a way I can flash or hack any 3g windows mobile phone so it will work with this sim? If I put it in my tornado I get the message "The SIM card is missing or is not valid", and from the searching I have done so far I believe an unlocked 3g phone will give a similar message.
Will it just require the CID to be set to the operators number or will it be something in the radio part of the firmware?
I hope someone can help me because I can't bare the thought of having to use a 'normal' mobile

help to unlock XDA Exec

Following Buzz's installation instuctions I am stuck with these two items.
9. Activate Radio even without Sim in it saying something about no Sim)
15. Flash your original Radio ROM. Do not upgrade the bootloader until you restored an original radio rom.
I think I am just about there with number 15 (with the resource on this site) but can not find anything on #9.
I know a lot of people say that it is already unlocked, but it seems unlocked to a few networks.

hi, XDA Execs should be unlocked
Does it ask you to enter the unlock code if u enter another sim?
If it doesn't then it's unlocked as far as i know.
What makes you believe that it's locked to a few netwroks, maybe it's because you're trying to find a non-existent umts signal...
Turning the radio on means turning flight mode off (and for the purposes of unlocking you do that without a sim)
Hope that helps.
I take it the UMTS is another name for 3G. My BT account is a normal non 3G account. Is it a case that I need to alter some of the settings, the networks it lists are...
@VF-UK
@ O2-UK
@ Orange
Is ther anything I should try....
umm, what happens if you insert a non-o2 sim into your phone?
If it's continually searching for a signal, it might be trying to search for a dodgy 3G/UMTS signal
in which case try going to phone settings, then in the band tab , select GSM instead of auto or wcdma
In the worse case scenario, if/when you flashed the radio 0.00.00, you might have had some problem with your USB (See the unlocking thread)
Thanks for all your help.
I think I have now got to the bottom of this. The fact is that BT use the VF network. The phone logs onto this, so I guess this is normal. However the signal strength never gets above 2 bars, is this normal?

Not anymore, dude. BT sold BT Cellnet (now O2 plc) a little while ago, but now they have started their own mobile service again (called BT Mobile) BUT piggybacking Vodafone's network.

O2 UK 3G help appreciated.

Hello everybody,
I apologise in advance if there exists an answer elsewhere, but I have been searching for the past week to no avail. I'd appreciate if somebody could point me to the right thread/direction.
I upgraded from my stock mda vario2 rom, to the latest schaps (WM6).
Everything works ultra fine but I there is no 3G! I have tried a few different radios and right now i'm on 1.43. I still cannot make video phone calls. The icon is stuck on G. I'm in east london btw.
I believe my O2 uk settings are right though , to te best of my novice knowledge that is.
Again I apologise if this is already addressed in another thread or wiki. Mods, please delete my post if it is a repitition.
Appreciate any help.
Cheers!
you have a tmobile phone or an o2 phone? goto phone settings and check its set to auto
Thanks for the reply,
I have the t-mobile's mda vario2. Tried that already but its still on G.
i have the same problem with an orange 3100. it will only find G not 3G. i have even tried swapping sims but no luck. i have tried all the different settings cabs i can find but no luck
i'm using an orange spv m3100 with no problems on o2uk, and i had 1.43 until yersterday.
o2's signal seems to be inferior to that of orange; i.e. 3g reception not as good
for example i do not get a 3g signal at home on o2, but did on orange, however i do get a 3g signal outside and in other places (on o2)
goggle the site for the field test software.

Call O2 customer service and ask whether you have 3G access activated on your SIM card. I have bought O2 pay as you go SIM card some time ago and it did not access 3G at all, since the very beginning on any 3G phone. Somewhere on the receipt or SIM pack (don't remember now) I've found sth like 'SIM 2G' so that way I figured out card is not meant to log into 3G. But I never bothered to call CS anyway, as I very rarely use that SIM.
Thanks guys,
I'll try all ur suggestions, I did try swapping sims with my wife, hers is an O2 sim which actually has the letter 3G on it, but nope its still Ging on me. I will give O2 a call.

What am i doing wrong?

Hello all,
I have tried unlocking my blue angel through the sim unlock tool,
ive trawled the pages of the thread to try find an answer. Ive posted in that thread what i get when i try to unlock. Could people please have a look and see if they have any solutions. I am just wondering whether this unlock sim tool will allow me to use the phone on the THREE network?
Many thanks
Sportyfr
anyone please?
You know, you are not being very descriptive.
Where did you get the unlock tool?
How did you run it?
What errors are showing up on the screen when you put the SIM into the phone?
What model of phone do you have?
the blueangel is NOT 3g (except the cdma harrier version) so no you wont be able to use a THREE sim card in it, (or if you can three will cut you off quick as they dont like people not using their network (they us o2s network for 2g so whenever someones in only 2g signal area its costing 3 money))

[Q] T-Mobile G2 on AU - Vodafone

Hi everyone,
i recently picked up a G2 on a US trip and am currently trying to set it up to work on the AU vodafone network.
i have gone through the sim "unlock" process, so it should be free to accept any sim card. (it also doesnt prompt me for an unlock code anymore, so im assuming it worked)
when i put the vodafone sim card in the phone, it detects the sim (there is the sim folder in the menu, with the vodafone sim options) and when i use "*#*#4636#*#* i see that there is something in the signal strength (-97dBm 8 asu).
BUT
when i goto settings ->wireless & networks -> mobile networks -> network operators i get an error saying "error while searching for networks"
any ideas?
Shouldn't this be in the G2 forum, not the DZ one ?
Thread moved to G2 General.
I am very interested to know how everything works out for you when you get it resolved.
Im moving to Melbourne from San Francisco in 3 weeks and I am on the fence if I should get a Iphone 4 or a HTC g2
*currently own a HTC Evo ..sadly i have to sell it

welcome to the club my friend
Unfortunately we have the same issue as you but we haven't find a solution yet. So far i have figured out that the phone after unlocking cannot read properly CID and MNCMCC codes from sim.

jee... sounds like the club to be in
5 days now i am trying for a solution. So far nothing to say. Just that users with same problem increase day by day. This might be good as htc will have to pay attention.
i dont know if its me, or if anyone else has noticed this, but if you change the band (auto - USA - Euro - Japan - Aus - Aus2)
then go and try to search for networks, the speed that the error comes up is different... its always the same error though....

You are right about that.
hi, i guess i need to join this club .. any progress for the solution?
I'm using a G2 on Vodafone AU and having no problems at all ...
If I click search networks it sort of just stops immediately with VodafoneAU down the bottom.
The one issue I'm having is that numbers are formatted for US ... anyone know how I change this?
I'm not sure if this is a real long-shot but I had some strange problems with my old Vodafone sim in a HTC Magic. I ended up just going into a Vodafone store and asking for a new SIM and the problems vanished immediately. They give you a new SIM on the spot free so it may be worth a try?
Is your phone working unlocked with the tmobile sim? If it isn't you're got the problem a lot of people have been having with unlocking the G2.
Otherwise, try rebooting your phone with your AU sim search for networks automatically and enter your APN settings. Alternatively if it doesnt find networks, go to Vodafone to get a new sim card. I'm also on Vodafone and I'm not having any problems with my current Tmobile Phone (Cliq) and G2 coming in the mail
Fixed by rooting and gfree
Hi! I had this exact same problem: unlocked a T-mobile G2 bought in the US so that I could use it on Greece's Vodaphone network. After unlocking and trying to check for networks, it would just say "Error while searching for networks".
Solution: I found the solution here: http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Subsidy_Unlock.2C_SuperCID.2C_and_Radio_S-OFF which describes an extra security measure that was taken on these phones and why you get this error because of it. The fix, described in detail on that page, involves routing your phone and then running a program to change this security "feature".
I followed the directions on that wiki page and it worked perfectly! It now connects to my vodaphone network here, and can see other networks that are around.
Note that as this is altering the software on your phone, it probably voids any warranty. But, I'll say with my US t-mobile G2 it worked very smoothly.
Hope this gives some insight to any others having this problem!

[Q] How to fix baseband/radio to include new operator [WAS issue after sim switch]

Hey there,
TL;DR : phone stuck on roaming network, unable to find other networks when scanning.
I've been reading alot around here for a while since a few months, and I'm now asking for help about an issue that I don't know how to fix it.
I'm using a S-ON One V in France (primoU).
I've changed my network operator last week. There are 4 real operators in France (Orange - 208-01, Free - 208-15, Bouygues 208-20 and SFR - 208-10). I've moved from a virtual operator (Prixtel - SFR network) to Free. Free has launched its network last year and has contracted a roaming agreement with Orange to use its network.
My issue is that my phone is stuck on Orange network and is unable to "view" the others and therefore unable to register on Free network. I'm pretty sure that it's a software issue because : i) I was able to scan and see all networks with this ROM, prior changing the sim card, ii) I have a Windows phone right under the hand with the same operator and it's able to scan and view the 4 networks and iii) checking the MCC and the MNC gives the code 208-01. I've performed a crossed check, too, and my HOV still shows the issue with the other sim card, while the Lumia is able to view 3 networks (all but Free) with mine.
It wouldn't be much a big deal since Orange has an excellent quality network if Free wasn't restricting data access on roaming (to cut the costly usage fee, seemingly).
When facing this problem, I was using Omega 2.5.0 with IronMan kernel for a whole month.
As Omega has became extremely laggy and unstable in less than 3 weeks, I thought I would kill two birds with one stone by changing to a new ROM. So I moved to C-Bean with Hellboy-CM10 kernel.
And still the same issue. As with CM10, CyanSense and Shpongle.
So I flashed back to stock ROM with stock kernel (and keeping TWRP recovery). Still the issue.
I then found this thread wich is somewhat related, since the "error while scanning for network" occured sometimes with Shpongle-based (and so AOSP-based) ROMs.
But I wonder why I still face this problem with the stock ROM and why the "error while scanning for network" still poped up when I tested CM-based ROMs (CM10 and CyanSense), while my phone was still S-ON (which shoud prevent radio flashing, as far as I know).
So I went through the Sensation thread about fixing the radio and RIL and I jumped to the conclusion that I may be looking in the wrong way, since I should have fixed the problem when flashing the stock ROM.
Now I've S-OFF the phone and gathered some infos.
Radio (gsm.vers.baseband) : 20.79a.30.0835U_3831.24.01.30_M
RIL (gsm.version.ril-impl) : HTC-RIL 2.2.0039HM (strangely enough, GetRIL shows "unknown")
CID : 61915329
I don't know what to do know now. I'm afraid to mess up the whole thing with somewhat random flashs.
What should I do to fix it?
Thanks for reading.
I've flashed the RUU and the phone keeps recognising the roaming network only.
How can I fix it if the problem is still there with a 100% stock software/firmware ?
OK so I put my former sim card in and performed a network search. I found all the networks available. I changed absolutely nothing else.
Could it possibly be an hardware malfunction between the phone and the sim cards from the provider (since I've been able to reproduce the issue with other sim cards from the same provider) ?
Okay, last bump before I give up.
A crossed check was performed by technicians operator in shop. They recorded the impossibility for my HOV to scan and view the Free network and sent me back to HTC.
I took some time to explain the problem to the HTC call-center guy. And he bounced me back because they don't care since the phone is working even if it's in roaming 100% of time.
As it has been suggested to me by an IT guy, it could be the baseband/radio firmware that may not be up-to-date, as the Free operator has entered the marketplace in early 2013.
Do you know if it's possible and if there a way to fix the radio? :/
EDIT : I managed to borrow a HTC Wildfire Buzz, and it shows exactly the same issue as my One V...
