[Q] unlocked sgs but now shows no signal?

hi had a search around but unable to find anyone who has had the same issue
unlocked sgs from UK t mobile to use vodafone sim.
all was ok till i changed the setting to stop 3g to improve battery life, sgs went to no phone signal (blue circle with line through it on top bar). put 3g useage back on but still no signal
had a look at my phone/status:
network = vodafone uk
service state = out of service
mobile network state = disconnected
if i set network automatically it says 'registered on network'
if i select vodafone from list i get 'your sim card does not allow connection to this network'
i have hard reset the phone, locked it and unlocked again, but still the same
also tried with o2 sim and get the same problem
== t-mobile sim still works==
is there a solution out there?

Try to manually create another APN
EDIT: my bad...you meant no phone signal. I have no clue but hope that you'll get the help that you need.

what needs to be entered in the fields?

i've had this happen on two phones..........one was due to me messing up the nv_data files. the other was fixed by reflashing.
take your pick

i haven't had the phone flashed
i only used ADB to get the Network Control Key which i then use to unlock the phone
can you suggest the next step for me
i assume the professional unlockers use a flashing method, should i get it unlocked by one of them?

its possible the imei has been blocked

if blocked tmobile customer service said that i should hear 3 beeps when i try to make a call, but i get a message that 'not registered on the network'

could it still be blocked even though i do not get the 3 beeps?
if it is not blocked is there anyway i can get this working on a vodafone sim?

Cannot enable "Mobile network" after upgrade to latest FW

Hello,
i've just upgraded to the latest official OTA FW 3.08.405.3
Sense3.0 is great, but i cannot turn on mobile network anymore - i tried it both via Quick settings and Wireless settings menus - it cannot be enabled. And even worts is that it doesn't report any error msg and the 3G sign doesn't appear on status bar. There is noting in the log too...
Does anyone has the same problem?
I just wrote a mail to HTC support, but don't know if they track this as support channel...
This is terrible - i can't live without mobile network connection ...please help!

This might sound weird, but is there anything in APN setting?

Try to mess with the toggles. I have had similar problem. I constantly turned airplane mode on/off and switched from GSM to WCDMA. Finally it goes, if this isn't related to apn. Hope i helped.

10x a lot guys !
it didn't recover APN settings after upgrade
I previously checked them, and assumed that check-box is selected, but actually it was not. It should be colored in green, but actually it was in grey

Unable to re-enable Mobile Network for data-only SIM Japan -- possible bug?
Having a similar problem, some more details:
PHONE:
I am using an unlocked (but unrooted) Incredible S from Virgin Mobile Canada with a data-only BMobile SIM in Japan (runs on DoCoMo's network apparently). Android 2.3.3 (Virgin Canada circa August 2011).
PROBLEM:
Mobile Network intermittently gets disabled and cannot be re-enabled normally. APN is fine, SIM card (phone number) is still detected. Toggling Airplane Mode or Wireless Network does not work, Select Automatically returns "unable to connect, try again later", Search Networks and choosing DoCoMo returns "Your SIM card does not allow a connection to this network".
SOLUTION:
Only reproducible solution is to remove data-only SIM, insert voice&data SIM (from my SoftBank phone), now Mobile Network is available so re-enable it, power down and replace data-only SIM. Once restarted Mobile Network automatically enables. Obviously this is not a convenient fix.
Once was fixed by randomly hitting network settings in frustration, but I have not been able to reproduce this solution.
OBSERVATION:
When on wireless, Mobile Network is also greyed out. When Wireless Network is disabled, Mobile Network automatically enables properly (for the most part, at least once I suspect it did not).
Thus I feel like it's a bug, either in OS or DoCoMo's network, but BMobile and HTC both point the finger at each other and have no useful suggestions for me.
ASIDE:
I hear Android 2.3.5 is available for Incredible S, perhaps this fixes the problem. However, this update has not appeared in my updater -- is it possible that because I'm unlocked I've lost access to the update server?
Thanks in advance for any suggestions.

mobile network disconnected
Have also the same problem, tried all the above suggestions but none works. Phone only shows limited service but with x on the signal bar. BUt when i try to tap the sim tool kit, it displays "SIM toolkit not ready or unsupported".
Hope somebody here can help me. Thanks

SIM Unlock Code Screen Missing

Hi All,
I apologize in advance if that has been posted and responded to, but my searches have been unfruitful. My boss has the Motorola Droid 3, stock rom, NOT rooted on the Verizon network (in NYC). He will be traveling abroad to the mid-east and contacted VZW Global Services and they provided him with the SIM Unlock code.
I then proceeded to insert my AT&T SIM card into his phone and booted it up - in anticipation of the SIM Unlock Code screen so that when he gets to his destination country, all he'll have to do is insert the SIM card which he will purchase there.
Unfortunately, no such screen appeared. I was able to access the phone's other functions and was even able to go into Settings>Wireless Settings and switched the device to GSM/UMTS only (from the default 'Global' setting). Still, nothing occurred. I then forced it to search for a network (even though automatically connect was checked) and believe it or not, midway through its search, the phone completely rebooted on its own. I thought that maybe NOW, when the phone finishes loading, that it will ask me for the SIM Unlock Code. Well, it didn't. The phone just booted up normally and indicated that there was no service (bars with the red circle and slash through it).
We called Global Services back and they claimed that we will not see a SIM Unlock code for any US-Domestic carrier SIM cards (sounds fishy to me) and the SIM Unlock Code screen will appear ONLY when a Foreign/Non-US Carrier SIM Card is placed in the phone. My suspicion is that the Global Services rep doesn't know the difference b/t his a** and his elbow and was just saying anything that seemed plausible to get me off the phone. It would be VERY BAD if my boss travels to his destination and operates on the assumption that this will work once he inserts a foreign SIM card and for it not to work at all.
Any thoughts/insights into this would be VERY much appreciated and if this topic was already discussed on another thread, I would very much appreciate the link to that thread.
I have seen similar topics on other phone model threads, but none of the instructions in each of those respective threads had a solution that seemed applicable to this specific problem.
Many MANY thanks in advance!

You should most certainly see an unlock screen with a US based sim card. I used an old deactivated T-Mobile Sim card to get my unlock code prompt. try going to the phone dialer and enter *#*#4636#*#* - give it a sec and a menu will come up. In the menu scroll down a bit and you'll see a network selection bar. Tap the bar and select GSM Auto (PRL). You should immediately get a popup or perhapse after you back out of it. If not, scan for networks again. If it still gives you problems - PM me and we'll get it figured out.

network SIM unlock screen missing for T-Mobile US
Folks,
I am experiencing a similar issue as the original poster. No matter what I do, I can not get the Droid global (stock rom, v2.3.3) to attach to the T-Mobile network. If I follow the instructions"
*#*#4636#*#* - give it a sec and a menu will come up. In the menu scroll down a bit and you'll see a network selection bar. Tap the bar and select GSM Auto (PRL) ".
I see the screen momentarily flash the t-mobile network, then switch back to indicating that the network type is CMDA-1xrtt. Any guidance would be greatly appreciated.
BTW this sim works fine in a BB Bold 9000. Also it is just a simple voice/messaging sim - no data plan.
Never mind - after more research, seems I have a phone with the US carriers locked out. - off to see if I can update it

You can follow the guide to have the phone work and it will fix that.

You need to use a foreign Sim card, not an American one because Verizon disabled access to all other American gsm networks

I was to access the screen you mentioned however I was unable to get it to ask for my unlock code, any ideas?

I had the same issue. The unlock code was already put in. Though this may be, there is more you need to do to have it working on US carriers like AT&T.
The guide is here

I c, U have to use Non-US SIM CARD. otherwise U have to unlock the US radio first. but if U having trouble to pop the SIM Network Unlock Code screen, just put non-US SIM and set the mobile network from global to gsm/umts. these also apply to those whose troubled with subsidy lock, so they can input the code.

Worked for me with tmobile or att sim card in the phone. You have to backup rename the build.prop file in the system(Rename the old build.prop to build.bak) put the new build.prob file in the system, restart the phone and wa-la, it will ask you for an unlock code. Enter it give it 15 or so sec reboot the phone, select GSM/UMTS and wait 30sec to 2mins you will receive a signal.

No T-Mobile network

I took my girlfriends S1 on holiday with my 3 network sim in it, when we came home I put her T-mobile sim back in, now it will not connect to the T-Mob network, it will connect to 3G? Putting the sim in my SNote and all is well. I have since install a custom rom to see if that would help but still no good.
Galaxt S1 running CyanogenMod 10 nightlies.

Believe me I have taken the sim out and tried it in the "wrong way" lots of times. I have also looked at your solutions page before, very helpfull. But why will the sim work on one network but not on another, and the non working sim will work in another phone????

Check the modem on both phones.
If the phone that doesn't recognize T-mobile has a different modem, then load the modem that the phone that works has through oden or CWR.
Hope you know how to check the modem and load new ones.
Good luck

This will happen as T.Mobile may be using a different Radio band ..most likely you changed the APN and Network settings when you used it with another SIM Card , whilst abroad ...all you may had to do was check your Network Settings in menu> settings>wireless and Networks> Mobile Networks and reset it back for the T.Mobile network, initially
To understand this better read this http://en.wikipedia.org/wiki/UMTS_frequency_bands
at the same time since you upgraded by flashing to JB, you may have to select a new modem that is suitable for JB, you will find all modems at My Android Collections

Data but no calls
Me back again, I have tried all xx modems, reverted back to stock rom, then GB, them back to CM10. When I first turn on phone it finds network (i'm on a giffgaff sim now) it says GiffGaff at the bottom of the screen for about 2 seconds, then it says emergengy calls only. I can still connect to internet. APN settings correct, IMEI correct, In Settings - About Phone - Status, i'm connected to network, service status = out of service, mobile network state = connected, my phone number = unkown. Where can I go from here?

More
Another thing I have just noticed, when I take the sim OUTwhen the phone is still ON, the "no network" on the screen turns to giffgaff,

Try to set your phone number by following this guide , it was written for a Korean version, so just adjust it for your phone version.
