I bought a Desire (Orange UK locked and branded), unlocked it with an unlock code from HTCCode.com or similar and reflashed a stock ROM. Used it for around 6-9 months with no issues whatsoever. When I got my DHD I loaned it to my sister-in-law to borrow as her iPhone was playing up. After a few weeks she told me she was getting 'no signal'.
I checked the phone and I'm getting some strange symptoms. When using an O2 UK SIM (O2 is what has been used in it from purchase) it looks to be working okay (signal strength shows good) but when trying to make a call I get a "Mobile network not available" error. I tried manually setting the network and get the error "Your SIM card does not allow you to connect to this network." or "Unable to connect to this network at this time. Please try again later." All APN settings seem okay.
I have since been using it as a "play phone" and is now rooted, S-OFF and is running Oxygen-2.0.1 (Android 2.3.3).
Please help
You rung up O2? See if it is them.
Yeah, they say nothing to do with them. Also the SIM works in other phones.

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.

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....

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!

I've searched, read, and called my mobile provider (3 UK) to no avail, so I'm starting a fresh thread on this issue.
Relevant details:
Nokia E65 + 3 PAYG sim = ok
HTC Desire unlocked (from T-Mobile) + 3 PAYG sim = "Your sim card does not allow a connection to this network"
HTC Desire above, + O2 + Virgin sim = ok
From what I've learned this has nothing to do with Android os, ROM or RUU etc., and is purely a setting/sim/connection/whatever problem. Or is it?
I bought an unlocked T-mob-branded Desire which works with o2/virgin sims, but selecting my 3 network results in the "Your sim card does not allow a connection to this network" message - yet same sim is fine in my Nokia. Which I cannot work out as that implies it's a combination of phone+network, surely?
When I first got the phone, unpacked it, 3 sim in, it worked, so I rooted w. Unrevoked it and it still worked, then I Nandroid-backup'd (which I still have), then I tried I think Cyan rom 6ish, and Oxygen 2 rc6 with a Goldcard in place [goldcard has nothing to do with sim/connection, just flashing, correct?], no service/not allowed on network; same with oxygen rom. So I nandroided-restored and still no luck.
I unrooted by RUU-ing with:
RUU_Bravo_Froyo_HTC_WWE_2.29.405.5_Radio_32.49.00. 32U_5.11.05.27_release_signed.exe
(I'm on 3 so tried RUU_Bravo_H3G_UK_1.22.771.1_Radio_32.36.00.28U_4.06.00.
02_2_release_127568_signed.exe to get a '3-rom'd phone' but I can't downgrade-which is fine by me)
so I'm back to Froyo 2.2 stock/whatever it's called, and no luck still. I mention this as I'm sure all this rom-ing has absolutely nothing to do with it but would like to be clear.
Has anyone any idea what causes this occur - not connecting that is - would 'disconnecting from network, romming, loading a new rom w/ sim, connecting and getting maybe kicked off' be the case? Or is this certainly a problem with the sim and this phone and the network; or can somehow a phone be unlocked only on certain rom and not transfer (certain this is not correct) to another - unbranding via goldcard + RUU 2.29..... has been done numerous times by people yet I seem to get this problem.
Long post, but if someone can definitely help it would be greatly appreciated - while comments like 'have you rebooted' are nice, yes, I have many many times, wipes settings, factory restored data, input apn settings, *#4636#*#* doesn't show anything I can really find of use (I tried selecting GSM only, WCDAM only, neither work) and I've tried manually/automatically connecting to network but am plagued with my "Your sim card does not allow a connection to this network" message. Which ultimately makes my £300 phone as much use as an iPhone 4 being held wrong.
I cannot understand how my sim worked before on the same phone, but now after tinkering (nothing of which I think can effect this problem) it's not working again. Apart from my old Nokia.
goto *#*#4636#*#* and post your signal strength (in dbm) and LAC and CID values. It will also be good if you could attach output of logcat -b radio.
This is a well known problem with a no known answer.
Is the number stored correctly - i.e. it hasn't lost the '+' from a number starting 44?

I had the same problem two weeks ago when I returned from my holidays. I put in my 3 UK sim and it refused to connect with that same error. Sim worked perfectly in other phones.
Finally 3 UK advised me to do a factory reset on my from the Settings->Storage menu which resolved the issue. You seem to have done a full restore from a RUU which probably should be equal to doing a factory reset. But it's probably worth while doing it anyway in case the issue was with the /data or cache partition which for some reason might not have been cleaned by the RUU.
Well, I *think* I've fixed this (for me at least) - just waited a few days and tested to make sure it wasn't a 'ymmv' quick quip fix.
Basically, I'm on 3 - 3G only - and phone was set to 'WCDMA (3G) preferred' - with low signal/reception (-113dbm) it seemingly tries to get the 2G signals around (Orange-whom 3 piggyback[ed] on in low 3G areas; and O2) while changing to 'WCDMA Only' forced it to only try 3G networks - 3.
So, try this:
Key in, but don't 'call': *#*#4636#*#*
Select Phone Information
Near bottom, Set preferred network type to: WCDMA Only
Fixed it for me instantly. Three mobile UK still has -111dbm as it's best reception here but now at least I can connect to it
Let me know if this fixes it for you (clearly, if you're on a 2G-only network selecting GSM only (2G) may work).
checked your IMEI matches from *#06# and the back of the phone?
Yep, IMEIs match. I think it's (been) purely a network choice/connection issue, at least for me.
hi all. I was as usual using my xperia j but 3g signal was low so I installed signal booster app and after boosting signal the app asked with a popup window to enter network unlock password. I without thinking anything entered 12345 and after this it said wrong network password. since this happened I am getting error on Xperia J (st26i) that your sim doesn't allow connection to this network. I tried with many sims but no signal. It always shows all networks when search for network manually. But gives that above mentioned error when trying to connect to any searched network. I checked if my imei is blacklisted but there's no problem about imei. its clean. I flashed stock rom, custom rom but nothing helped. how to solve this strange error.
Mehul (nope imei does not match)

I'm currently in Taiwan for about a week, and am trying to use my T-mobile SGSII with a Taiwanese SIM card. I got my phone unlocked before I left, and I'm not getting any errors with the SIM card. However it looks like it's not working. I'm not seeing any network signal. If I try to search for a network it says "Error while searching for networks". If I try to select a network automatically, it says "Your SIM card does not allow a connection to this network."
Anything I'm missing?
Thanks!

Sim my be bad.... Check ur apn settings...make sure they r from the sim.
I went to el salvador and this girl kept dialing some numbers on keypad and #*# n they finally got it to work...if no luck take it to tech office
Sent from my SGH-T989 using xda app-developers app
Well I eventually gave up on getting the Taiwanese SIM card working, but now I'm back in the states and my phone can't seem to recognize my original T-mobile SIM card anymore. I can't get any sort of network connection, and I get the same error messages when trying to change the network settings. Wifi is working fine.
The SIM card is fine, because I popped it into an old unlocked dumb phone I had, and was able to make calls with it... any ideas?
Thanks!
So it looks like my phone is stuck in flight mode, although Wifi works. When I goto Settings > About Phone > Status, the Service state says "Radio off"...
hi. i just got this phone in the states before coming down to panama. it is verizon, but i called them and they gave me the code and now the phone is unlocked....but i can't get coverage here in panama. i've tried sim cards from a few of the local operators and none of them seem to work. i sure hope someone can help....here's what i've done so far: (oh, pls b patient, i'm a bit of a technophobe)
-unlocked sim. phone gives me sim lock is disabled message....that means i'm good to go, right/
-set phone to gsm only mode.
-software is androaid version 2.3.4
verizon global services told me that everything was as it should be and that the phone should work w/ a local sim card so i'm not really sure where to turn to......hopefully someone here can help. verizon also told me that the phone should work on the frequencies here. i have a claro sim card, but have also tried movistar, digicel, and masmovil. i was told that they use either 850 or 1900.
so, i'm totally stumped. hopefully i'm missing something stupid....btw, tried the sim in other phones (from europe and panama) and it worked w/ them. don't think it's a hadrware problem, but am i missing something? is there a setting change? do i need some kind of software update?
thanks!
update- get cell phone reception w/ gps on
don't know if this will help anyone get to the bottom of this issue, but i realized that when i have the gps on, i get full bar coverage. unfortunately, i can't leave the app on in the background. this makes me think it could be a hardware issue....bad antenna? anyone have any ideas
Same problem
I have the same issue as OP. Got my phone sim unlocked, and it runs on SenseMOD-2012-05-18-225643 Android 4.0.4.
For once I did a factory reset, skipped verizon activation (can´t do and won´t work because I´m not in the USA and do not have a verizon SIM or service), set my network preference to GSM/WCDMA, and the network wasn´t working.
Rebooted, my network is identified as soon as it starts, but then it goes to "No Service". Try to search for network but my carrier does not appear.
Any help?
EDIT:
Playing around with the phone, setting GSM as your network and restarting the phone let me make phone calls. No internet though and the APN was configured correctly. The "E" symbol for the internet blinked once in a while, but never got service.
Also, playing around some more, got my phone to not recognize the network again by removing the SIM another time. This sucks.
Hi Guys long time learcher, first time poster so please be kind if my n00bness starts to shine through.
So recently I brought a Tesco Branded Wildfire S A510e (believe 2012 model) second-hand. As soon as it came I used this site with my Macbook Air and got the phone bootloader unlocked, recovery finally installed and lastly flashed a nice custom rom with a new kernel.
My new network SIM card came through today, i decided to go with giffgaff because like tesco they are actually using the O2 network so I thought the SIM card would be compatible with the handset but alas as soon as I booted into my phone I was greeted with a SIM network unlock PIN prompt.
I done a bit of research and I discovered that my phone is SIM-LOCKED (if thats what S-ON means??) and to get it off I need to buy some kind of XTC Clip but unfortunately am feeling the pinch at the mo so I can't afford to order one. Instead I paid for a network unlock code from mobileunlocked.com (had used them before with a locked blackberry). I sent them my IMEI number, paid and waited for about 10 minutes and my unlock code arrived.
Eagerly I entered the code and it was accepted, the phone then displayed my menu screen etc. But I also noticed that I have no signal on the phone, i tried to scan for the network but I just got a "Error while searching for networks", I thought it might need a reboot so I did.
But when it booted up it asked me for the network unlock code again, I entered it again, it was accepted and the phone then displayed my menu screen but once again no signal, I tried to search for the network and once again same Error while searching message.
I shutdown the phone and manage to borrow my sons Tesco SIM to test, popped it in and turned it on. No code asked for, booted straight into the menu and looked, the phone has signal.
Tried my GiffGaff SIM again and still same problem. If I wait a message does pop up saying "mobile registered on network" but when I try to search for a network carrier a search prompt pops up for about half-a-second but then closes, No network operators are listed.
Has anyone else ever had this kind of problem??
Any feedback will be appreciated.
Thanks for reading.
I don't see where you activated the SIM that you got from GiffGaff. If you didn't, go to their site and click on, "Activate SIM" and follow the prompts.
Hello there,
Exactly the same thing happened to me yesterday also with a Wildfire S, and I found a way around it.
I flashed a stock ROM (Gingerbread, HTC Sense), and entered the unlock code, which actually unlocked the phone (calls and all).
After that I re-flashed the custom ROM I'd used previously and didn't get prompted for a code, the phone is still unlocked.
