I bought my Desire S from eBay which was Orange SIM locked and Orange branded.
After messing about with custom ROM's I set it back to S-ON and flashed the UK Orange RUU. It was working with an Orange SIM that I have, but rarely use.
I went to a high street phone unlocking guy earlier today and paid for him to unlock it. I didn't see exactly what he did, but he put a SIM in it and may have connected it to a small unlocking device. I asked him 'I can put any SIM in, yeah?' once he'd finished and he said yeah. I went to a nearby coffee shop and sat down, swapped the Orange SIM (which had a signal) with my giffgaff/o2 SIM and I also got a signal. 'great' I thought, 'his unlocking trick worked!'.
I put my giffgaff SIM back into my Galaxy S for the journey home, since I've got that all set up how I like it, and I put the Orange SIM that I don't use back into the Desire S.
Now that I'm home neither SIM is working
I thought to myself 'did the guy only temporarily unblock my phone?' but that can't be right because when I was sat in the coffee shop I rebooted the phone at least twice, if not three times, when I was swapping SIM's so a temporary fix would've been cancelled out then.
Is it because I tried to use a giffgaff/o2 SIM with an Orange branded RUU ROM? Would that have done something to my radio?
It sometimes displays 'limited service' on the lockscreen and displays 'no service' on the unlock screen bar.
I've tried switching it to GSM only in the menu's.
Should I S-Off the phone and flash a custom ROM to try and rectify the situation, so that I can use any SIM in the phone?
Could it be that his special SIM has dirtied the contacts in my phone?
It worked about 3 hours ago
Update:
I just picked it up and then noticed that I had a signal on giffgaff!
The signal has gone again but at least the SIM is working. Either there are local network troubles of the radio I'm using is not too good.
I'm going to go ahead and S-OFF, root and custom ROM to see if that helps signal strength.
Will a custom ROM install update the radio, or do I have to specifically flash a new radio?
So have you tried to use SIM in another phone?
I had same kind of issue. I called to customer service and they said that try SIM in another phone, then put it back to my phone and that solved the problem!
So I was changin my service provider and tested a new SIM in my phone(wasn't in operation yet) and then switched back to old SIM, then "no network". Randomly gave some signal but only few seconds at time.
Sorry for my english.. May be that I missed some points of your text But hopefully I helped!

I have had my m500 for quite a while, I unlocked it as soon as I bought it, as I prefer to use my o2 sim in it. Yesterday I decided to put my Orange sim in it, it would automatically divert my calls to an unknown number, so I had Orang give me a cancel all diverts code (**.....). Now when I go back to put my O2 sim in it, it turns on, but won't search for network signal, instead it says
"invalid or missing sim. you may still make emergency calls if your service provider supports it"
I know it was definately unlocked, just to make sure, I have even unlocked the phone again, but still, other than an Orange sim, nothing works.
Does anyone know how I can fix this problem? Thanks in advance
My MyTouch 4G slide has been sitting for a month or two after previously working fine. Now it powers up however it can't get a signal with my T-mobile SIM (or my wife's). I'm concerned that somehow the radio might have gotten fried. So far I've reflashed it back to stock, unrooted, and hard reset it a few times, nothing has worked.
If I go into Wireless & Networks, drop down to Mobile Networks, Then Network Operators, and "Search Networks", it takes a few moments and finds AT&T & T-Mobile (I'm in an area where my devices normally get full T-Mobile service). However when I try to connect to T-Mobile, I get a message saying "Your SIM card does not allow a connection to this network". Same SIM works fine in a G2, connected to T-Mobile.
Anyone have a way to test the phone radio, or perhaps have an idea on what it's issue is?
I have had this exact problem, and attempted the same solutions, but without success. Was working fine, and then 1hr later quit working and was not able to repair even after return to stock/deroot, etc. Doing warranted return, and just got replacement phone by mail for swap out from t-mo.
am a little worried about reroot and rerom in case I have another problem.
My device is doing the same thing. Not sure when it started... I havent used the MT4GS in a few weeks, picked it up and reset it back to stock everything, and it's not getting any service from any of my SIM cards. I unlocked it a while ago to use on AT&T prepaid SIM, and not even that will work... Any advice would be helpful...

I've used Z-Device Test by Zausan Innovacion Tecnologica to test just about everything on my phone.
I'm having a similar issue on mine after trying jupoeanutbear and failing. I have signal but data craps out at random times now.
Sent from my myTouch_4G_Slide using xda app-developers app
Purchased an HTC M8 from a friend that seems like was flashed to T-mobile. I tried everything and various roms (revolution, viper, bonestock) and the stock vzw RUU to get the phone back to verizon. The APN file is still showing all t-mobile files in it.
Also if I go into settings>Network preference: It shows all european networks ie: vodafone UK ,Claro dom,JP DOCOMO, all GSM/UMTS.
I called verizon to verify the IMEI and sim and they both checked out to be verizon, so I know its a verizon phone. Has the VZW logo on the back also.
I cannot make calls or get any internet connection with it. Tried changing all of the network settings, replaced the sim card and so far no go. Can anyone point me in the right direction for some help.I have searching and tried various procedures for the past 2 days without any luck.
Strange thing is the 4G icon is there and when i try to connect to the internet the bars below it become active but I always get the same message: Cannot connect to the internet.
The phone is rooted, TWRP, S-off and CID 11111111 also.
Thanks for any help !

Check your IMEI number, settings>about>status http://swappa.com/esn use this site to see if its bad or not. If it is, the phone was probably reported stolen or the person who bought it didn't pay the monthly amount for the phone, so Verizon would have blacklisted it
I called verizon and first verified that is was indeed a verizon phone which it is and it is ok to be activated. I took it to the store an they tried a new sim card but it did not work. No phone calls or data
No matter what RUU or rom i tried flashing when I check the apns-conf.xml file in System>etc it always ends up having T-mobile settings in there.
I have it rooted, S-off, SuperCID11111111, and nothing has worked so far. Very frustrated as I have been working on it going on 3 days. But not all is lost. I have have learned a lot trying to get it fixed. I just might end up sending it in to HTCand have them fix it. Sure would suck to have a $400 paper weight
Thanks for the reply..
At boot time, Android determines the correct network configuration based on the MCC and MNC from the SIM card and automatically configure all network settings.
I have a verizon HTC One M8 (had my imei verified at a verizon store and esn was clean) with a new sim card and yet all of the files in my system>etc>apns-config.xml file are showing T-mobile.
Also in settings>Network Preference>all of the carriers are coming up vodafone, CLARO DOM, JP DOCOMO Swisscom and they are all GSM/UMTS.
Does anyone know why its not loading the proper files from my sims MCC and MNC ? This has been driving me crazy for the past 3 days trying to figure this out.
I flashed stock RUU and am s-off, unlocked, Super CID 11111111. Have no idea what is causing this.Any help or pointing me in the right direction would be GREATLY appreciated.
Well, Sent it in for repair. Told the Customer rep the phone was roooted, Rom'ed, CID'ed and that I never got to activate it.
So just waiting to see what happens and will post when I find out the verdict.
BTW, they could tell when I gave them the IMEI the day that the phone was rooted. Is that possible ? Sure came as a surprise to me. Gave the lady the IMEI # and after about 1 minute she came back on and told me the phone was rooted on May 1st. I have no idea if that is true because I have only had the phone for 1 week now.
Hello, I'm having a major problem with my phone and I'd be extremely grateful for any help or expertise.
PROBLEM:
I cannot get any kind of CDMA signal on TWO Verizon HTC M8 (I didn't post in that specific thread for a reason, I'll explain, please don't move it).
--------------------------------------------------------
HOW THIS HAPPENED:
The first phone, I was using as normal and it was fully functional.. One night i flashed a ROM and ended up falling asleep before if built the ART cache (so it was just playing the bootanimation) and the next morning I awoke to find the boot animation still running. The phone wasn't hot but ever since then I could never get any kind of CDMA service (so i can't use my carrier.)
The second one i just bought and put my sim in and BAM. Same problem.
--------------------------------------------------------
MORE DETAILS ON THE PROBLEM:
If i put my sim in, i can usually get 4G data but can NEVER get any lower bands. CDMA settings are greyed out in settings. This persists across ROMs and radio firmwares. My immediate thought was to get a new sim but my sim works absolutely fine in my LG G2. The sim is cut from a microsim but the point there is it worked fine before (and still works in my G2) and it didn't shift in the tray. I tried my friend's sim from an Iphone 5s and it did the same thing. I've tried everything i possibly know to do. This problem has basically cost me $400 dollars or 2 M8s.
Even if i go into the phone info hiddenmenu, i cannot select the CDMA or EvDo bands by themselves.
Hey Everyone. So I just received my unlocked 7 Pro from OnePlus' website, and trying to use it on T-Mobile. Took my SIM card out of my Pixel 2 XL and popped it in. Noticed when I first powered on at the beginning of setup, there is no cellular signal. Went through setup and still no signal. Even updated to 9.5.13.GM21AA and STILL no signal. It's weird because it detects the SIM card in slot 1, and even shows my phone number on the SIM, but shows Network as "Unknown" and "Disconnected, Radio Off, etc." Same exact thing on SIM slot 2. The correct APN is selected and everything. SIM still works perfectly fine in my 2 XL. Even tried a friend's T-Mobile SIM card, and the same thing. It detects the number, but no signal. Did I get a lemon? Don't think it's the SIM since I tried two different ones, and my current one still works in my 2 XL.
TL;DR
Cellular network not working even though it detects the SIM card. Does this sound like a hardware issue? Already got a RMA number to send it back, but if it's a simple fix, I'd rather do that instead of having to ship it out and wait a week to get a replacement.
Any help is much appreciated. Thanks in advance!
have you registered to network or dialed *#*#4636#*#* are you rooted or no different options to take the project fi - t apn makes my whole network setting disappear lol i fixed it google dont play nice
i have the same issue now with my 7Pro, did you manage to get it fixed?
