[Q] “Your SIM card does not allow a connection to this network”

Yes, this old chestnut.
I realise that this problem is as old as Android itself, but it actually appears to be a bunch of different problems that manifest with the same symptom. I've tried all of the solutions I can find, and none of them seem to work.
I have an Orange UK branded Desire S that I recently acquired second-hand off eBay. To begin with, everything worked fine, but the phone hadn't been updated in a while so I applied all the OTA updates (3 in total), one after the other. After the first two it was also working fine, but after the third update it stopped connecting to the Orange network.
When I attempt to connect to the Orange network manually, I get “Your SIM card does not allow a connection to this network”. When I try the same SIM in another phone, it works fine. I unlocked the phone using a code and tried a Vodafone SIM, but that didn't work either. I've tried removing the battery overnight, no luck. I searched a IMEI database to see if it was blocked, and it isn't. I've tried repeatedly switching airplane mode on/off, which doesn't help. I've tried a hard reset, through the phone menu and also via the boot menu, without success.
When I type *#*#4636#*#* to enter the service menu, I can see that the phone is receiving a signal, so the antenna's working OK.
Now here comes the odd part. When I try to change the wireless band to 'WCDMA Only', it refuses to change and stays put on 'WCDMA/GSM' mode. It doesn't matter if I use the service menu or go through the 'Mobile Networks' settings, it still refuses to change.
I'm open to the concept of flashing a custom ROM, but I don't want to invalidate any warranty I may have unless that's the only option. I'd like to try flashing an RUU, but I can't find a suitable one. The only Orange ROM in this post appears to be French language:

Any comments would be much appreciated. Thanks in advance.

Hi,
I'm having the exact same issue with a HTC Sensation 4G (T-Mobile) on stock ICS.
I bought this second hand phone and bring it back to Venezuela. The phone worked swell with local carriers but suddenly lost signal and got the infamous “Your SIM card does not allow a connection to this network” message.
I've tried every solution posted on the net with no results, leaving rooting as the last resort.
So, before I begin rooting my phone I just wanted to ask if you found any solution to this. :fingers-crossed:
Any help would be much appreciated! :good:

So,
I've rooted my phone. used HTCdev, juopunutbear, clockworkmod, installed Superuser and got super CID. Also, I called my carrier and checked that my IMEI was not blacklisted (just to be sure).
Messing around with the hboot I found something that I'm not quite sure what it means, in the SIMLOCK menu I found this message:
FAT32 init OK
Open MCCMNC file fail
Open CID file fail
Process done, reboot device?
<vol up> Yes
I've changed the CID to the original stock and got the same message. I don't know what it means and if it is related to my problem. I'm still using the stock rom (OTA ICS 4.0.3 T-MOBILE) planning to install OrDroid 9.0.0.
I really need some guidance over here. :crying:

Sorry to hear that. I'm still stuck with it.
I've flashed Ordroid 9.0 and the same error appears everytime I try to get signal from any carrier.
Someone told me that I should try flashing the radios or change my IMEI but I really don't know how to do it and I'm afraid I could permanently damage my phone.
Still waiting for fresh ideas to try.

Good news! (at least for me)
After I've tried almost all to solve the issue I took the phone to my carrier to get my sim card changed. they told me that someone has reported my phone as stolen in my previous carrier. So I went to the other carrier with my proof of purchase and they unblocked my phone IMEI right away.
If by any Chance you're having this same issue make your phone checked by your carrier for any kind of locks before messing with your phone.
Hope my experience will help any of you.

Nandroid backup.
Flash an RUU & see if that fixes it. (Make sure you flash a GingerBread RUU)
If it works, then flash 3.32 unlocked fw, flash recovery & restore & see if it works.
Otherwise, go to HTC.

Hello Guys,

Following are the deatails of my phone:
Radio version :1.96.00wf
OS Ver : 5.2.21889 (21889.5.0.87)
Manila ver : 2.5.20132227.0
ROM ver: Mighty ROM
ROM date : 06/20/2010
CPU QComm(R) 7600
Please let me know if any other info is required.
Before writing in here, I tried every possible way to find my answer in existing threads but could not.
waiting for some positive replies.
Thanks..

Are you using the correct radio. Sometimes flashing can reset the radio.

+1, someone just had the exact same issue, and he found that the radio had reverted to the WV instead of WU. Make sure you're still on an unlocked radio...

Dear arrrghhh,
I am so thankful that you replied. I googled and checked a lot of pages on internet. It seems that my phone is security unlocked as it displays "SIM Unlocked" but the radio in my phone (1.96.00wf) is either works in US or a locked version of radio.
As my phone is already unlocked so I believe that I dont need to buy an unlock code again. I just need to upgrade the radio.
Is my understanding correct?

Your phone should stay sim unlocked once it is unlocked. Try replacing the radio, and let us know.
Also you might have better luck searching here than on google for something this specific.

You would have better luck asking in the sim unlocking threads. I am sure it is all probably covered there in the first post.

Desire S not registering on network

Hello,
I have this Desire S here which is on official 2.3.5 GB rom, sense 3 and unlocked. Everything else is working apart from the sim is not getting registered to the network and it keeps giving a "x" sign above signal notifier. I tried to manually register the sim "Orange" on its network, which it registered once and after 2 minutes removed the registration automatically.
can you please help me in this regard?
shall i flash the radio?
shall i flash the new rom?
or is it some hardware isuue (assuming it is working because i can search the operators manually.)

Hi few days ago,
I've had similar issue with my lady's phone, she just spilled some liquid ( ? ) over the phone
and when i opened it, the phone was wet inside...
There was no network at all..
I dried it up through the night, and it came back to normal...
You can try to clean simcard and phone connectors as well ( carefully )
If that's one of the above mentioned causes, there is a big chance you may recover your phone...
If the problem persists, you might also check

for more direct help

thanks for the tip. let me open the phone and give it a go... will update you if it worked or not

ok, i have checked it, cleaned the sim jacket, phone is not water damage either...
sim jacket is fine because it do ask me for sim pin code when i turn the phone on. the sim card is not blocked either.
can you please look into this issue for me?
thanks

Could you give more details? Such as how you unlocked the device? Any mods that you may have installed?

Just a thought....
Is/was it simlocked
Is your phone ( or its software ) branded ( carrier locked )
Is it still stock or rooted and modded already...
Could you specify the radio version- your device is having installed...

yea i tried but with other sim Only GSM mode is not working however WCDMA mode is working

Is it possible that the phone is locked to some GSM operator and you card is for another?

i don't know. how to know that if it is so.

Is this a radio problem?

Hi guys, So i have a GB HTC Sensation and have moved to the US I brought a AT&T Sim and assumed i could just use it since my phone is fulled S-OFF and Perm Rooted. It keeps asking me for my Sim unlock code so i found it and it says sim unlocked sucessfull But it does not find any signal what so ever and when i turn my phone on and off again i have to keep typing the sim unlock code in. when i go to Settings-wireless&networks-Mobile networks-Network operators It says error while seaching for networks. Im not sure why...
So when i went from sence to ICS I remember i had to flash a new radio and when i did as i was on Orange in england i selected the Orange one. So im assuming that the phone is locked to the Orange network with that radio (I dont know much about radios soo please tell me if im wrong)
So will i have to flash an AT&T radio to my phone? if so can someone point me to a thread on how and where to do so as i can not remember
Thanks alot guys!

i really don't know but you can use getril app from playstore
it will tell you the best combination of radio/ril

Just an idea.
Go to your dialer, put in *#*#4636#*#*
Then do Phone Information
Once in there hit the menu button and select Radio Band
And then select USA Band
See if that does anything for you.

Use any guie forum brow

Try this http://iphone-unlock.blogspot.com/2012/08/how-to-unlock-htc-sensation-4g.html and this http://forum.xda-developers.com/showthread.php?t=1693491
But generically try to wipe cache and dalvik cache and/or wipe data and/or try to flash another ROM and another Radio.
If not, may be hardware problem. Verify that the case is fully adjusted to phone, and try also to clean contacts.
