[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?

Not registered on Network Message please help

I bought a galaxy s3 I905 today and when I put in my Vodafone sim it said it want a sim network lock pin so I used the *#197328640# method to unlock it and it worked

Thanks

[Q] KitKat update causing sim problems?

I've got a Verizon XT1060 and am having an issue I can't work out. I brought it to Thailand last year whilst running rooted stock Jellybean, bought a SIM, popped it in and was immediately up with working voice and data. Since then, I unlocked the bootloader with Sunshine and flashed to a rooted stock VZW KitKat ROM. That was working great in the States. I brought it to Thailand this week, popped in the same SIM card and found that voice works but data does not.
Symptoms;
1. I get a "Sorry this SIM card is from an unknown source" when the phone boots up.
2. Service state under phone status says "Voice: In service / Data: Out of service"
3. 'Under phone status, 'Mobile network state' says 'disconnected' and 'my phone number' says 'unknown' and 'Mobile network type' says 'unknown' but the IMEI is there
4. No APNs were populated
What I've tried:
1. I've tried setting the preferred mobile network to both Global and LTE/GSM/UMTS
2. Enabled global data roaming access
3. Manually set the APN
4. Manually selected the network operator
5. Rebooted a bunch of times after changing the above settings.
Misc:
Baseband version: MSM8960PRO_BP_2323.038.123.00R
I'm rather confused with the situation. The phone is unlocked as the same SIM card worked perfectly last year. I'm planning on stopping by the local carrier's shop and asking them to check out the SIM but wanted to make sure I wasn't missing anything else that could be causing this problem. I can't imagine the KitKat update blocking access to foreign SIMs but you never know with Verizon.
Any ideas/hints would be greatly appreciated!

[Q] Your sim card does not allow a connection to the network

I have a moto X 1st gen here in India. Its unlocked,not rooted. One fine day it thrower me an error "your sim card does not allow a connection to a network". And I am without network in my mobile.
My IMEI is same as in the battery
Device is not rooted
Sim card works fine in other mobiles
Tried different sim cards but still same problem
Didn't fiddled with any network settings.
After reading through XDA threads I did
Cleared data/cache
Restored the stock firmware again.
Did that network menu reset to switch radio on and off many times
Not able to get any network signal at all. Is there anything I am missing?

Samsung note 9 N9600 VZW network issue

Hi guys,
My toy is a samsung note N 9600 and its factory unlocked. Last week ported out from T-mobile to keep my original number and facing a wried issue.
The day I ported out from T-mobile, VZW network couldnt be recognized when I tried to activate the VZW sim card. "No network connection." and no call or text can be made. However, after I RESET my device to factory model, it SUCCESSFULLY recognized VZW and LTE function works well. Sounds wried? The story doesnt end here.
Yesterday after I turned off the VZW sim card by accident-- n9600 is a dual sim card which allows you to turn either sim card off-- the network connection lost again, im not talking about LTE connection, but all network service including internet, phone call and text function. Tried a lot to get the connection back but failed. Guess what? RESET, THEN VZW comes back!!! Being driven by curiosity, I turned off the sim card agian, and then, as my expect, no network connection. Ok, rest---works---turning off sim card---no connection---reset……
I am really annoyed by this and have no idea why it is. So if anyone of you have clue of it, plz let me know. Thank you in advance!
Teddy
