sarcasim is a good thing but maybe you aren't comprehending what i am saying duhh!!
i own NSPRO box and have unlocked the galaxy S phones quite frequently, the phone is sim unlocked for any sim card or gsm carrier, what i am saying has nothing to do with unlocking with the sim card in( which i tried for ****s and giggles). the problem is the vibrant is not recognized on the network , i have tried my sim and several other t-mobile sims the phone doedn't receive signal on t-mobile network or simple mobile( which is a NVO of t-mobile)so what i am asking is does t-mobile block imei's from their network and is their a solution other then changing imei of the phone which i do not wish to do although i can change imei i will not since it is illegal.
the problem
let me clarify it actually says on the screen
"not registered on network"
anyway to register it on system???
its unlocked and works on at&t, h2o and all other gsm carriers except t-mobile and simple mobile
clone another imei, that will solve this problem, There is an app that allows you to give you a new I D # to your phone
I am same problem here everytime try to make call it says "Not Registered on the Network", SIM card works fine on different phone, also other SIM when inserted on Vibrant gives same message.
Under Settings> Wireless> Mobile network settings does not allow access...
Can someone help resolve this situation.
Thanks,
I am also
having the same problem. I purchased a used Vibrant from my friend whom defaulted on his bill so he sold his phone to me. When I attempt to use the T Mobile prepaid SIM or a regular T Mobile SIM it will not allow me to connect to the network. It stays on (Searching) or (No Service) but the date and time updates so I know it is connecting, just not able to use the network. Is there anyway to get around this problem or do I need to root and unlock to go to another carrier?
Hi guys I am having similar issue, please help
I was using bionix 1.3.1 by team whiskey, whats your advice do I change to ICS, will that solve the problem or simple radio upgrade will solve the matter? I have gone through several sites and found that this problem is with many android mobiles since last 2-3 years. Is there no solution to this yet! I have tried Airplane mode, removing battery, downloading autocut and all those basic methods but to no help ...
I have the same problem, did anybody find a solution?
I tried everything, flashed to stock, GB, ICS, JB.
My phone is unlocked and it only works on AT&T, the sim card is good, as I'm using it on my backup phone.

Same here. This all happened when I let my friend borrow my phone to put his SIM on it. It was a prepaid Simple Mobile SIM. It didn't work but after I went to put my SIM card back into my Vibrant, the phone never got service.
Funny thing is, my SIM works on one of my older phones, so I know the SIM still works, but my Vibe gets messages like "out of service" and "not registered on network" even through it still has some bars.
I think the problems relates to this thread: http://forum.xda-developers.com/showthread.php?p=37703090#post37703090
Somehow the bands on your device is messed up so you never get a signal. Not sure how to fix it but any solutions would be great.
I am here in Singapore with my Verizon Galaxy S4 and it is indeed unlocked, however, there's a small issue.
I picked up a pre-paid SIM card from Singtel. Inserted into the phone, was able to add the APN information. Get to the last step that says dial *363 to activate the SIM card and that's where the wheels fell off the wagon. Every time I dialed *363 (per the instructions on the SIM card) the phone kept coming back with an Invalid MMI code..
Eventually, the only way to activate the SIM card was to have the SingTel put the SIM in his phone and do the *363 to go through the process.
Anyone else experience something similar with a pre-paid SIM over seas?
I did not have this problem. I am using a prepaid SIM in europe (T-mobile de). I had to set the phone to GSM (or global), enter the APN info, and then dial the activation number. It all went well, without problems.

I wonder if it is the MMI code that SingTel uses. Anyway, definitely doesn't work for Singapore.
This is an unmodified AT&T Atrix4G, which is supposed to be unlocked, but it was a warranty replacement and I believe it was carrier locked by the first owner, before ATR&T gave it to me. Last year, AT&T's unlock code didn't unlock it, and they and Moto both claimed to be stumped when we found this out last year. The phone did recognize AT&T NVMO SIMs, but would only say "network error" when I tried a T-Mob SIM.
So this week I went back to T-Mob, thinking maybe the phone IS unlocked but needs a T-Mob APN entered to work with a T-Mob SIM. Phone was working fine, and the T-Mob guy tried to boot the phone with a T-Mob SIM card in it. The phone asked for an unlock code, we put in the one AT&T had previously generated (and confirmed, no error there) and instead the phone rejected the SIM and said "emergency mode only".
Now, it won't recognize any SIM card, not the original AT&T card (AT&T also supplied a new card in case the old one was the problem) nor the T-Mobile. All it wants to do is boot to emergency mode, or ask for an unlock code again.
I've tried the factory reset cold-boot, that didn't help either.
The phone has just gone psychotic and doesn't like ANY SIM card. Is that nuts or what?
Does anyone have any idea what I can do to get the phone working again? With AT&T or T-Mob, I don't care, I'd just like it to work as a phone again, even if that wipes all the data from it.
AT&T's store, and their local "tech center", were both dumbfounded. They claim they've never seen a phone that just won't work, won't unlock, won't take any SIM card before.
Hi XDA community,
Few months back i had purchased LG G Flex 2 for my dad who is a reliance CDMA subscriber and was looking for a decent phone which is hard to fimd in india.
i had bought a phone from a guy who specializes in imported cdma phones.
Everything was working fine till end of April, 2016. We had received a message from rcom saying they upgrading all their cdma customers to 4G. So we need to get a new sim from reliance store.
So i was worried if my dad's phone would work on gsm too or not?
So i tried to put the GSM sim in the phone and check if it works as the phone supports both gsm and cdma.
so this is what i did,
1. in mobile network selected gsm/lte and removed the sim card which in turn automatically rebooted the phone.
2. while the phone rebooting i swapped my cdma sim with vodafone gsm sim.
3. the phone received the signal and i was able to make a call. i was delighted.
4. now i selected the cdma/evdo option in mobile network and followed the above process and re swapped with reliance CDMA sim. But to my surprise the phone shows "Service Disabled" , whereas same CDMA sim worked fine with my CDMA only hanset.
Also, i was not able to check the network option as the phone disabled the Mobile Network option.
5. Now i tried with another reliance CDMA SIM and swapped with the actual reliance CDMA SIM. The phone showed the signal and I could make a call.
6. Again i reswapped the new Reliance CDMA sim with my vodafone gsm sim. To my surprise the phone was showing "Service Disabled", whereas it worked fine on gsm only phone. So i also tried with the reliance CDMA sim that had worked and the phone said "Service Disabled". In the whole process of swapping reswapping and juggling between so many sims, I forgot what option was last checked in mobile network.
7. this strange behaviour seems as if the phone is accepting the New SIM and rejecting it once swapped reswapped with something else.
NOTE :
1. Phone when purchased was already rooted having the following app already installed 1) root browser, 2) supersu 3) shortcut master(lite).
2. Phone is on android Lollipop and software info says LS996ZV7
3. The phone backcover says LG U+LTE x8, and i m not sure if its a sprint variant.
I am trying to search web since last 3 days on the issue but nothing is helping.
Its my dads business phone and he yelling at me for screwing it. He is using an alternate phone for time being but I wanna resolve the problem at earliest.
I have an lg k8+ model x210ulm that i want to use with cricket. The phone is fully unlocked and will accept any sim from any carrier but has an odd behaviour that wont let me use my own sim.
I bought a feesh sim from cricket and when i put it in and set it up it will register with crickets apn and mobile network settibg. I get data and it shows up in the about network as connected and working. It shows cricket carrier in notificstion and i can get texts and even voice mail. But ........
I cannot use the dialer. Upon connection there is no error toast or anything it just imnedistely hangs up.
I can use my wifes my sons or my friends sims in the phone and after a reboot works perfectly. But when i put mine in it stops.
Also my sim works fine in any other unlocked device or cricket device.
Any clue as to wth is going on
Ok so after talking to lg and really that was frustrating. Why because the rep told me it the phone was carrier locked to us cellular which i knew it wasnt because its advertised as being unlocked and well us cellular put up an advert a few years ago stating that all thier phones are unlocked.
So after that i went ahead and talked to a rep at us cellular who assured me it was unlocked and checked the imei for me and sent me link to the advert about thier phones being unlocked.
Back to lg and got another rep this time who knew a lil about something but not much. Could not tell me any thing though.
Now back to cricket where we tested my girlfriends sim in my phone to which it worked and mine in her phone to which it worked. We put the sims in my aristo 2 and fortune 2 and both sims worked. But when i put my sim back in my my k8+(2018) once again every thing works fine but you cannot make or recieve phone calls.
We also tested the voice mail app and and thier what qualifies as a carrier app and it registers. The sim registers in about phone shows service and is connected. Shows the phone number every thing works.
Just not the phone Dialer app
So is there any one out there at all that has had an issue like this before. Any one that can help me figure out what the problem is. This is so crazy that my sim wont work and every one elses will.
Could it be something i did using dialer codes? Any cLues at akl
So here we are months later and im still having sim issues with my k8+ ulm. I ended up buying a brand new device and i tried my provisioned sim card with it not working but literally every other sim card works fine.
I have switched from cricket to assist wireless now who is run or what ever by sprint and i can get the sim card to work for a couple days before switching it to another phone but the main issue is that i get a error popup stating that the sim card has locked and that i need to power cycle and call customer service.
But i made a ton of changes by adding all the system apps from sprint including sprinthiddenmenu and any other apk that was on the tribute dynasty they came from. I also went through the file system and made any prop changes or any thing else that was needed to enable sprint.
At this point id flash a sprint modem but i cant find a cv1 device provisioned under sprint
