Can't Get Network Signal - help! - 8125, K-JAM, P4300, MDA Vario ROM Development

Hi,
I have a g3 O2 XDA Mini S (bought of ebay unlocked sim free) and after some flashing and unlocking I've popped in my SIMs from Orange and O2 and neither can find the network. Other phones can so it's not a reception issue. I started on O2 wm5, followed the g3 guide with Button then Tmob. Then to Diamond and back to tmob and then up to slim v3. I put the sim in then (it's in my other phone hence why it wasn't in during the flashing) and it couldn't find a signal. I downgraded back to the base O2 incase it had locked itself but that can't see an O2 payg SIM either. Using the lokiwiz0.3a I got a garbled sim unlock code so it looks like it is still unlocked. Any ideas??! I've searched but there are so many threads to go through with ambiguous titles..
Thanks!

it is very detail for solved your problem.
if you can not read it ,told me ,i can help you.
Hi Spinny, I'm not sure if this is right but I think the prophet is not a 3G phone ( which uses the UMTS connection) but is a 2G phone running on GSM. Your phone is probably unlocked and able to use sims from T mobile ,Orange ,O2 and Vodafone etc.
As far as I know , 3G phones run on UMTS when there is an available connection but will switch to GSM when the UMTS not available. Therefore it connects to your Orange network and works but you will be getting billed by 3 network and you wouldn't be able to use video calling.Hope that helps. There is a lot of info here too http://www.pdadb.net/index.php?m=specs&id=456&view=1

Unlocked Tilt and No Service on T-Mobile Sim

I have just unlocked my tilt with Kaiser SimUnlocker. I put my T-Mobile sim card but no connection. Always searching... I put my friends Cingular sim card (old at&t) and still no connection. So I thought my phone was broken so I took it to local AT&T store and one of the rep says 'maybe it's the sim card'. And he grabs one of his new AT&T sim card and voila! connected. Have anyone had that problem? What can I do to fix this? My T-Mobile sim card is says 38.01e on the card next to my sim serial number. Is it my sim card? Do I have to get a new sim card? I've just got this sim card about 2 months ago. Any suggestion?
I assume you reflashed an appropriate radio after unlocking?
I would try flashing a new radio anyway to see if that sorts your problem.
I've tried severa different radio roms with no luck. Right now I've reflashed back to US At&T rom. I still no clue why my T-Mobile sim will not connect to the network...
On AT&T, the tilt requires the newer AT&T 3G cards - thus probably why the Cingular card didn't work. Are you sure the SIM unlock process worked for you? If your T-mobile SIM is that new, I can't imagine you needing a new T-Mobile SIM. The T-Mobile SIM has worked in another phone?

That's strange b/c my Cingular card works on my tilt.
I unlocked my AT&T Tilt and then put in my (almost 1 year old) t-mobile sim card and it worked immediately without any problems. I used the original radio as directed in the unlocking tutorial. So it sounds like maybe you should do the unlocking procedure again. ?
Hope this helps,
stacy
did you even try putting ur sim into another phone and see if it works? just making sure u covered everything here
Maybe you are locked into 3G
Go under Phone/Options/Band and make sure the top is either set to Auto or GSM
Thanks for all the replys...
I have tried just about everything...
I know it's unlock b/c it does not ask for unlock code no more. I have hp hw6945 that is also unlocked and works perfect in there. It connects almost instantly so I know my sim card works too. Also tried changing band setting to Auto and 900/1800 and everything and no luck... Going crazy and frustrated... about to just sell it to some at&t user and buy a new one, try again.
Just to let you xda'ers know that when I tried to unlock it for the first time I tried with spl-1.56 on it as a factory (dummy me) then tried SuperCid unlock which changed to spl-1.0 then proceded with rest of the unlock. Maybe that messed something up?
I've had that issue but my sim card with t-mobile was 4 years old. Had to purchase a new sim card and everything worked fine after that. With my old sim card, the tilt wouldn't even recognize the card.
Anybody want to donate an old T-Mobile SIM to me
buddy had same issue just happen.. he had to go to tmobile and show them the sim wasnt working they gave him a new @ no charge
I had a old cingular card that came with my Razr and it worked fine in my 8525 Hermes, but it said no service in my 8925 tilt. I would try a new t-mobile card.

HTC Mozart SIM unlock

Hi all,
Just seeking some help, I've recently got a HTC Mozart and I've upgraded it to unlocked Mango. Problem is I bought it locked to Orange UK and I'm with Vodafone. I've just today got an unlock code and it's worked in accepting the SIM card but there is no signal and I can't call anyone. My contacts and messages have come up though.
Any ideas of what the issue could be?
Thanks for Looking.
Have you tried using the connection manager to switch it over to Vodafone?
Yes, I've switched it to Vodafone Contract on connection manager. I've rang vodafone to see if they are maybe blocking the signal as it's a new phone but because the sim works in my old phone they say it's 100% a problem with the phone.
Could it be that I typed in the code after I had upgraded to custom unlocked mango ROM?
And also I hear you have to type the unlock code twice on orange phones but I can't type it in again, there's no option to.
This phone was bought less than a week ago, I can and am considering returning it. I've rang HTC and they think it's a problem with the handset.
I too just got this phone like you, from orange, had it unlocked and have come to the conclusion it just doesn't work on vodafone.
When I did a search for networks on the phone tmobile, orange and 3 uk all came up but not vodafone. I also tried my 3 uk sim and it worked fine. i'm now back on my blackberry as it's the only phone i have which will work with the vodafone sim.
the phone i am keeping. vodafone i am not.
Thanks Livett, that's what I was thinking I tried a t-mobile sim and it worked fine. I think I'm going to change it for an Omnia 7 as I've still got a couple of months of my contract left and my other phone is a £10 vodafone branded phone. Worst phone I've ever experienced. I won't be staying with vodafone though.
Hi, I just thought i'd give you an update.
I updated to Mango last night on this phone and managed to get the sim working. It flits between Edge, HSPA and GPRS connections. Do Vodafone even have 3G? Either way it doesn't work, it's atrocious. I managed to send a text to myself on HSPA, recieved it, picked up the handset and then the signal dropped.
I think it's safe to assume Vodafone does work on this phone as it's unlocked, it's just Vodafone is so **** at coverage it's not even worth it.
Thanks.

Just had SIM unlocked and now have no network

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!

[Completed] Sim Card Error

Hi ,
I recently bought Vodafone Smart Ultra 6, which is obviously locked to Vodafone. I did all the start-up settings and everything was running fine. Since my actual network carrier was EE ( Orange ) I unlocked the phone, which worked alright up until the point where it suddenly the phone would lose reception and regain it at random times. I thought that since my sim was really old and cut with a template to fit the nano sim requirement, I messed something up. I didn't mind swapping carriers since I wasn't that happy with my tarrif, so I ordered GiffGaff sim, got my PAC number from EE and activated my new GiffGaff sim with my old number.
I know for a fact that the sim works, because I tried it on different device, but my phone acts like it's locked to EE after the unlocking I did from vodafone. Every sim card I insert is unrecognisable by the phone, except the old EE card which is no longer active.
I tried doing factory restore, which didn't do anything.
Dialing *#*#4636#*#* and turning the radio on and off -> still nothing
I have no other idea what to do and I can't find any solution on the internet.
My android is 5.1.1 which I read that has similar problems on different devices, but none of the solutions I found worked for me.
Any help will be much appreciated.
I am sorry if the post is confusing and doesn't make much sense :/
To summarise:
The phone was locked to Vodafone and Unlocked immediately with an EE card inside
Now the phone constantly shows NO SIM CARD - Emergency Calls Only ( tried on GiffGaff and Vodafone Sim )
No Network Connection - Can't connect ( tried on EE Orange after initially unlocking, the sim is no longer active)
Thanks in advance!
