So, other SIMs are working with different radio versions? I think that your phone is fine.

Might be a trouble from operator side. Check Telenor SIM on other phone.
If it will work - flash factory ship ROM on yor DHD and flash original radion version.
It's strange mystical part, but stock ROM resolves a lot of troubles
No success

Thanks for reply other sims works fine with ever version of radio only that telenor sim doesn't work as before flashing a new rom i put my DHD in airplane mode i think that is the main problem...
if i do same process with other sim ( before flashing other rom put DHD in airplane mode ) then that sim network will not work also..those sims will work fine in other cellphone.
like i use the same process( before flashing other rom put DHD in airplane mode ) with Mobilink sim it shows signals but when i call or sms it says Mobile network not available (in screenshot)
and when i use Telenor it says no service (in screenshot)
when i try to choose a mobile network manually in settings it says "your sim doesn't allow a connection to this network" (in screenshot).
and when i try to choose a mobile network automatically in settings it says "Can't connect to this network right now try again latter" (in screenshot).
other sims works fine
all screenshots are attached with other information
please help me.please :crying:

This Is strange... Is your device made in china or taiwan?
Reason for asking this question is that, taiwanese made DHD normally generate certain problems out of the bloom that usually makes no sense.
From my understanding, When you flash a rom, you format the data partition and this partition holds every change you made to the os during the time of use. So there isnt any reason why a mode you left your phone in before flashing another rom should have such an effect.
Have you tried inserting another sim from the same mobile operator?
Edit:: And what rom is that? It looks nice. Can you give me a link to it?

It cant be a simlock. It takes more than airplane mode to throw a device in sim lock.
And if it was sim lock, it would only accept one particular sim card and not accept some simcards and reject others.
These made in taiwan Desire HDs develop problems that dont mount up to any proper explanation, as i already said.
Like mine, its taiwanese made and when i take out the simcard, it runs smoothly, but as soon as i insert a simcard, the device becomes laggy/slow. i have tried so many things but they all dont seem to work. This isnt the only problem, there are others.
This only leaves me with the conclusion that, the taiwan made DHDs are immetations/fake.

Hi i just bought a used HTC Desire HD and when i start it it says "T Mobile"
When i insert SIM card in it (Swedish) it says ""Limited service", i put in PIN but only limited service and then i have no signal...
I have tryed 4 different SIM, 3 swedish 1 thailand. Same thing.
When i go to settings network i can search for network operaters, then all the network i can have in sweden comes but i dosent matter wich one i choose it says : Your sim card does not allow connection to this network, which is very strange because if i have TELENOR sim inside and choose TELENOT it says the same...
Please someone help me
My guess would be that your phone is branded (SimLock) You have to have a t-Mobile sim card for it to work to you ave to get rid of the lock. Plenty of info about unlocking DHD in the forums.

downgrading and unlocking are different things even if you have downgraded the simlock stays on unless you unlock it.
yes but i use the ultimate multi tool, and did all. sim-unlock also and when check after it says sim unlock.
why is it not so i can put in code from network. it was like that with other phones wich is network locked. but this i put pin code and then limited service only.
so how do i then unlock sim ?
could it be that the lock is on your sim not the phone, try another SIM
have tryed 3 different swedish sim + 1 thai sim no working...
get the phone contacts and all from sim and pin. but no signal. finding the sim network in list but cant conect to it.... your sim does not allow connection. ?!?!

what does 'properly unlocked' mean ?
I say you might have unlocked the bootloader,bit the phone still has SIM lock.

hmm, so you saying if i go back to the shop and get them to unlock properly, it might let me use the o2 sim???
is there anything i can do....having only a modest knowledge of these issues?
and in reply to properly...sorry i wasnt specific - i meant that when you put an o2 sim in and turn it on...it doesnt ask for a pin or code to unlock the phone??
Well did you buy it in a O2 shop? If yes,then there appears to be a problem with you handset. If you DIDN'T buy it in a O2 shop(which means any other,T-Mobile,3,etc.) Then you're out of luck because it it probably SIM locked to that carrier.
You should bring back the handset back to the shop and ask them to remove the SIM lock.
ok, so here we go...
Went to the shop and they say the phone is unlocked. When i put an o2 sim card in, it does not require a pin when the phone switches on.
It works with tmobile sim, orange, virgin just not o2....
so it is unlocked just wont take o2.....
any ideas why?
its originally a tmobile wildfire - spoken to tmobile and they say they have completly unlocked.....

do you have any other o2 sim to test it ?
you should also go and change your sim, might be rly the SIM problem ...here changing sim costs 10 bucks, i hope its free in your case.
im afraid im a step ahead - all o2 sims dont work - i had a brand new 3g sim sent out by o2 and have tried a pay as you go sim on o2 - still wont work with any o2 sim....
any ideas?

a ok, i didnt read that one... lets try to keep this on one thread. why dont you try flashing stock rom again... i mean its worth a shot... i guess you dont use any custom roms atm ? or even try flashin any custom rom, just to try it ... if it doesn't work then, well, we will see it's a very strange problem.
did you try connecting with 2g, and not 3g...
or maybe changing setting in *#*#3646#*#* then phone information, then set preffered network type... and try changing those also ... First try this, and if it doesnt help then try what i wrote above.
ok,well - had a read of your suggestion and only a slight problem with it...i am a real beginner when it comes to this so apologies but rom flash???
Also looked at the *#*# suggestion...unsure how to do that - did try typing that into the keypad on the phone part but it didn't do anything..
apologies im not up to speed..any way to simplify for me?
oh, and also someone has suggested going into the bootloader so i took out the sim and battery, put it all back in and held down volume and power. at the bootloader menu, i selected simlock. when i pressed it the following was displayed..
fat 32 init ok
open mccmnc file fail
open cid file fail
process done, reboot?
does this help explain anything??

i guess you didnt unlock via xtc clip... you should write the code that i told u on dialer pad, it should immediately open a meny, i will make photos when i come home as a more detailed guide k ?
ok, just to save you some time if you dont need to spend it - the phone was unlocked at a local shop - no idea how they did it - although im guessing badly...
i typed that code in - when i enter the final * the code just disappears and it does nothing. I did enter the code without the last * and it said mmi running but then said incorrect mmi...

Using official (as well as silviu's ROM) for Samsung Galaxy S4 mIni duos (i9192) on Jelly Bean, I could use HSPA+ network (when available). However my phone was rebooting everytime I activated my 3G/HSPA+ on one of the two sim cards... very annoying, my only solution was to deactivate 3G and work on Wi-Fi to avoid constant rebooting.
Therefore I tried kitkat version : it's even worse concerning rebooting plus I have no HSPA+ at all (same phone, same sim card, same network, same place) !! Modified ROM of Silviu corrected rebooting issue, but still no HSPA+ anymore !!
Can someone help ?

Hello, thank you for your quick reply !
I'm from BELGIUM and tried a lot of things without success... you are my last hope to solve.
I'm afraid I was too fast in saying rebooting issue was solved with your kitkat rom : it is not rebooting but I still loose network on both sim cards after activating 3G on one of them (and using it). Behaviour is slightly different as I don't get immediately pin code screen or rebooting, but I have to reboot and enter pin codes again to reactivate network.
You may be right about changing modem : what do you suggest ? I found one of your posts on this forum with a lot of modems : are they all usable with kitkat ?

Strange behavior u have there. unfortunately no, only 3 modems for now for KitKat . Russia, India, Chile
I think i only had one full network drop on both SIM since Kitkat and that was caused by Phone.apk crash . But my network came back online in 10 15 seconds or so.
On Jb, i had more Phone.apk crashes but those fully lock the phone and i had to force shutdown . ~1 / week or so
I have no clue what to advise u unfortunately. Sorry
Did u try without PIN-codes ? I don`t use them

Let me resume, I have now 1 more issue on Kitkat comparing to JB :
a) loosing network when both sim cards active AND 3g active on one of them (i.e. be asked for pin codes, unexpected rebooting, just nothing to see but get voicemail when calling my own numbers from external phone)
b) no HSPA+ (Kitkat only)
I tried to downgrade to JB in order to have at least HSPA+, but it gives an error ! ?
Please help how to proceed for downgrade to JB stock rom ?!

I've noticed there is a new version for India... do you have only the MODEM: I9192DDUCNH1 for download and is this modem compatible if I install it together with PDA I9192XXUCNG2 (I don't want to reinstall everything, but only have bugs corrected in modem) ??

Here u find almost all modems
Same issue here.
Same issue here. After upgrading to Kitkat, never been able to connect again to HSPA+ signal. When I try network mode "GSM/WCDMA" I get EDGE signal then when I choose network mode to "WCDMA" only, I have a signal but no internet and the symbol "H+" or "H" doesn't appear on the top of the screen.
It's a UK vodafone G4 which I got unlocked and was using my O2 sim without issues. I ported the O2 number to iD Mobile (three network) and can use SMS as well as mobile data but calling doesn't work at all.
I put a Three sim in and it's exactly the same issue. The iD sim works fine in other phones. Other sim cards work fine in the G4. It's just iD and Three sims that won't make or receive calls.
I since used LGUP to install a kdz file (V20c-234-15) in the hope anything vodafone will be removed but that didn't make any difference. In the phone Settings if I check Network Status it shows the iD connections, in Status it shows Unknown Phone Number, in Network Mode it displays 2G/3G/4G, APN shows all correct iD settings. If I search for Available Networks it displays all the usual UK networks and only lets me select iD network.
Customer service said wait a few more days after porting and suggested a faulty sim (yet works in other phones) but after both iD and Three sims showing the same issue I've not much hope in their suggestions.
I know others that bought the vodafone G4 and unlocked it for Three haven't had any issues. I only found 1 other post online that has the exact same issue as me but their post hasn't updated since last month.
I don't know what to try. Other sims work, just not iD/Three. Any ideas for me to try?
I've since tried another kdz file for lollipop as I know for sure the sim worked before the number was ported before the phone was upgraded to MM.
Still doesn't work for calls, only data and SMS.
Can anyone offer more suggestions to try?

This is a weird problem maybe your problem is modem or wrong kdz file. Downlaod right file and flash again and be sure that you click refrush that is makes wipe in LGUP.(I use LGUP)

Thanks,
I had this problem with stock rom too though. I only started trying more kdz files in the hope that might work. Issue started the moment my number ported from O2 to iD Mobile.
Wierdly the phone doesn't like Three network sims either now and those worked fine before the number port happened.
Am really confused

Hey guys,
yesterday my phone got updated to the 3.23 Version. Since then my phone is getting no signal to my provider nor mobile network.
I tried WIPE USER DATA which also doesnt work. The sim works fine in my iphone xs...
I also tried to manually apply APN settings.
After i plug in the SIM card it asks for my pin. I enter the pin and it unlocks the SIM but no signal.
I only get a Question Mark at the Status Bar.
Do you guys have any similar problems?
