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.

So you have a T-Mobile sim that won't work on a vibrant?
???

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 tried to get my phone unlocked today, however ever since then my phone hasn't been able to connect to any networks. I had to give my Imei number to get in unlocked, is there some way this could have been used to block my phone?

Yes in theory it could. Try the old sim and see if it works.
To block an imei requires access to the network systems, although you could phone them up and perhaps maliciously block an imei.
Did you use a reputable unlocker?
I used one off ebay however they had 15000 positive feedback.
I rang T-mobile and they say my phone is not blacklisted but its also not been unlocked. I dont know if this is true as when I put my unlock code in it said unlock ok and now when I put another network sim in it doesnt ask for the code. Ive since tried to use an orange sim card in it and this works but I dont know if this is anything to do with the fact that Orange and T-mobile have merged.
If it isnt unlocked then i dont know where to put a new unlock code in.

Lol you are fine.
Tmobile don't know it is unlocked. It worked fine if the sim doesn't ask for the code now.
If an orange sim works then phone is OK. What is original problem again?
Lol sorry I havent been very clear.
Ive bought a Tesco mobile sim and that is what I want to use however when I try this sim it wont connect to the network. Ive also tried a O2 sim with the same result however an Orange sim does work
I really have no idea what could be causing it and ringing Tesco/T-mobile has been no help at all lol.
Might be a stupid question but are you sure you can get Tesco Mobile signal? Both Tesco Mobile and o2 use the o2 network. So that's probably worth checking.

Ive tried it in my girlfriends iphone and it works perfectly so I cant imagine its the signal. I'm totally flummoxed, the only thing I can think of is if the phone isnt unlocked, but then why then does the orange sim card work?
OK I've come to the conclusion that it hasn't been unlocked and the reason the Orange sim card works is something to do with their networks being joined. If this is the case is there a way of re-entering the sim unlock code?
TMOBILE has blocked your sim, you may need to root

TMOBILE has blocked your sim, you may need to root. My experience is this: I have a rooted HTC that works fine, however when I put the sim in my S2 or a second T-Mobile phone I get the error message "cannot connect to network" even though I have 5 bars.
hey everyone, i'm about to buy AT&T Galaxy Note through Craigslist.
seller states that it is unlocked, but not rooted. is there anyway for me to verify it is unlocked?
is it simply inserting my T-Mobile SIM card and making sure it doesn't say phone is locked, enter network lock control key, etc...?

Yes all you have to do is insert your sim and it will either connect, or you will get a prompt to enter the PIN. If you want to use 3G/4Gish though, you will have to root and flash the t-mo radio that's in dev section.
P.S. With most Samsung phones, you can check for the unlock by dialing *#7465625# and it will tell you directly if there's a network lock on it, but Samsung disabled this on the skyrocket IIRC and kept it disabled on the note

perfect. thanks for the quick response!
When I inserted a tmo sim into mine nothing happened except for it would show the sim phone number under the Settings app. No signal bars either. This is on a stock unlocked phone.

You might have to wait a few minutes for it to acquire the signal.. Is the sim active? Sometimes inactive Sims don't connect, but I put my old t-mo sim in & it had a signal in 20-30 seconds.
Easiest way to tell is to reboot the phone after you put a non-at$t sim in. If it's locked it will ask for network control key .

Yeah it was an active sim. Ten minutes later with no results. It wouldn't work without the APN at all and the Tmo rep didn't want to go through all of that (it was his sim).

It is that "simple"..
If you insert your non-AT&T (including it's MVNOs which are considered AT&T also), and it's LOCKED, it will ask you for the unlock code. If it doesn't, it has been unlocked permanently.
If after doing this, it does show your number under about, but you don't get a signal. This might be an indication of how well the phone gets a signal or how good/bad the signal is, on your carrier in the area you are testing in.
An after thought is to check the versions in the about and research. You may have acquired a hacker/tinkerer's phone that may have played further with the phone's settings and or flashed a different modem. It may also be indicative of why s/he is selling it, possibly faulty.. YMMV
You have to flash T-Mo compatible modem http://forum.xda-developers.com/showthread.php?t=1573568
thanks everyone. i bought a note from someone an hour after my initial post and it was unlocked.
i'm enjoying this phone/tablet/phablet/whatever u wanna call it on tmobile. still getting used to the size, but the display is beautiful.
in a first moment, the carrier signal was ok, but data wasn't working. so i called the carrier, get the correct APN, and the everything was fine for 5 minutes, for phone calls, data network. But suddenly signal was lost, and never got back. Factory reset, the signal bars still off, with an X. Tried to locate the carrier manually, but it doenst work. What can I do now? I will try another sim card to check if it works. How do i know the phone is carrier locked?
If its the AT&T version (presumably, since this is the AT&T variant section) it should carrier locked, unless you obtained the unlock code; or otherwise purchased it SIM unlocked from a 3rd party vendor.
On the other hand, if you were able to connect to the network at all, it is probably not carrier locked. Likewise, if it was locked, it would ask for the code when you inserted the SIM.
I think something else is going on. Even if it as SIM locked or bad SIM, I believe it should still read the network as being present. It would just not let you connect to the network.
Although, replacing the SIM is an easy and cheap thing to try. At least to eliminate it as the issue.
I'm on AT&T,but just bought a rooted S4 off someone with a Verizon ROM on it. Would I just need to flash a AT&T ROM for the S4 to be able to get the SIM card to work with AT&T?
Any help appreciated.
Same here. My friend gave me his S4 today and it is Verizon and running on the stock ROM. However, I am on AT&T. From what I hear this phone comes factory unlocked so you just plug in the SIM and it should be okay. Is there anything else that I need to know if I want to use this phone as my main?

After a brief visit with AT&T today, they installed a SIM card from their carrier into my phone, but it would not get speeds grater than EDGE at the time. 3G may have been possible, but it didn't see it right away. Also, they had to update the APN settings in the Settings -> More settings -> Mobile networks -> Access Point Names. Lastly, after searching the internet, Verizon carrier locks the GSM in the states. In other words, they make it so you can use GSM OUTSIDE the US but not allow AT&T or T-Mobile SIMS to be used in their devices. This is a carrier lock, not SIM lock, so they can get around the whole "well, our phones are sold SIM unlocked" bs. After calling a level two tech support, he told me that there is no such thing as a carrier lock or SIM lock, and he could not give me a code. The phone was able to make a voice call and send a normal text, but data sucked.

Sorry to disagree, but my SCH-i545 works on the AT&T network with an AT&T SIM installed.
I only get Edge because that's the only band that VZ and AT&T has in common in this area. Swapping out a SIM isn't going to fix that.
What you're finding about GSM locks applies to pre-LTE phones. The LTE phones are not SIM locked, aren't carrier locked. Period.
