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.

Hi all. Just after a little help if possible.
Bought a 2nd hand S2 and was told it was locked to Virgin, before I bought it I made sure I saw the buyer make a call with the Virgin SIM on the phone.
I downgraded from ICS to 2.3.5, rooted the phone and used unlock tool from Market to unlock the phone. Tried several SIM cards in the phone, but I cannot connect to any mobile networks. In Phone Status, it shows phone number, signal strength etc but when I try and make a call is shows ‘Not Registered on Network’
I went out and bought a PAYG Virgin SIM card as I thought the unlock may not have worked correctly and exact same thing happens. Put the Virgin SIM in my unlocked HTC Desire and works fine. So, its deffo the phone that has the problem. I checked the IMEI number online to see if it had been blocked but it looks ok.
Any thoughts??
Thanks in advance.
Hi
A few things to check/try -
Does the IMEI number displayed by typing *#06# into the dialer match the IMEI number on the back of the phone (Under the battery)?
When you put a sim card in (other than Virgin) do you get a message from the phone asking for a network unlock code?
Does the network name of the Sim card appear in the status bar?
Which app did you use to unlock the phone? I've used Galaxy_S unlocker several times without any issue. (I install a ginger bread rom first, then insecure kernel, then root, then run Galaxy_S Unlock)

Check ur imei no dial *#06#
verify that imei no with the one beneath ur battery
if it same then try flashing the stock rom again and root it and try unlocking again using the unlock soft from play store
Yes, the IMEI number matches so no problem there. Have been onto several free IMEI check sites to see if the IMEI number is blocked and it shows as not being blocked. How reliable these sites are I do not know...
No, no unlock message comes on. However, I locked the phone again when rooted and put the Virgin SIM in, which it should be locked to so should work, and I got a SIM unlock message? So, when the phone is locked, it does ask for unlock code, when unlocked using the app, lock code doesn't appear.
I do not get the name of the network in the status bar. When I look at the phones status, it does show a signal strength, and I do sometimes get signal bars but when I try and use the phone I get 'Not registered on network'
I used Galaxy_S app and did everything that you have done!
Have tried flashing stock rom, rooting and unlocking and nothing seems to work.
Worried that I may have bought a nice, expensive media player...
If your IMEI matches up with the one under the battery then I really don't know why you can't get a signal. Maybe someone else on here will give you some better advise. It sounds to me like you did everything right. The obvious thing would be if the phone is on the blacklist (stolen phone, or reported as stolen, 2 different things!). I wasn't aware of any sites that can tell you if the phone is reported as stolen so can't comment on how accurate they are.
Hope you get it sorted, it's the best phone out there at the moment so would be a shame if you can't make calls on it.
have you tried with diferent modem? or diferent rom?? or both at the same time?
for the modem try KI3 or KI4, seems to work pretty fine for almost everyone..
have you tried
hi have you tried going to
settings>wireless and network>mobile network>network operators
and checking the settings in there are set to autoselect network.
if this does'nt work +1 for all posts below.
hope it does.
also not sure but i think sim lock is set in security settings and the pasword for unlocking is stored on the sim that password was put on. anyone feel free to correct if this statement is wrong. many thanks
Hi!
Rooted with cmahendra's offline Lelus method (and to anyone who's done that, my hat is off to you).
**SHORT VERSION**
Sim goes into the L9. I get bars that show network availability, however I am not able to connect/make/receive phone calls.
**DETAILED VERSION**
Starts like this: I have my CM rooted Aria that works a-ok as far as the network. Phone message memory getting full all the time and incoming texts bounce back, with no way of knowing who sent them. Can't have that, so I buy a stock L9.
Sim works. I want to have Wi-Fi calling, which is the *only* reason I bought the L9. Wi-fi calling is not working: call up T-Mo and they say I need to give a 911 address and all will be well. Ok, done.
Sim works. But no Wi-Fi calling still. Call up T-Mo and they say "Ohhh! you need a "3G-B" (I don't think that stands for gigabyte) sim card" Ohhh and what's your phone model etc etc. I tell them "it's a no-brand phone I got overseas," they don't need to know the model: they didn't with the CM Aria. They're clicking settings on their screen other side of the phone while we're talking: I can feel it.
Sim *stops* working. Need a working phone, so let L9 aside and get a stock T-mo S2. Same issue, cell network not connecting.
Let me show THEM! Ha! I'll unlock it. Unlocked the S2.
Sim still doesn't work.
Put the Sim back in the rooted/unlocked Aria? Network works.
What settings do they have in their stock phones that disallow network connectivity, because in the CyanogenMod Aria I have the phone fully works, GPS, tether, etc etc. In their stock-from-T-Mobile phones, network = nada.
Thank you for reading.

What the heck are you asking? I don't see any understandable questions in your message. I see you blowing off steam.
It does look like T-Mobile cooked your sim. You may need a new one.
Call them again and ask for "Customer Retention" through the automated system. Those people are more knowledgeable. A new sim should be free if they killed it.
Also, a data plan is not required for wifi-calling.
T-Mobile will give you a SIM regardless. They are always free.
I'm not sure as I am unrooted, but most carriers block network access via files in the EFS folder. This folder is VERY delicate. Anything improperly changed here can render a phone useless. If the SIM works in another device, it's not the SIM. Have you tried a different SIM in your phone?
Also, if you're blocked from network access, when you make a call, you should be prompted with, "We're sorry, but this device has been blocked from network access." If you do not get that prompt, then there is something wrong with the phone itself, be it software or hardware.
Looks like the L9 isn't registering in their system. Where did you buy the phone, blacklisted perhaps?
As for fried your sim, why does it still work in the Aria.
As for 3G-B, you probably need a newer sim, others call it a 4G sim... They should send you one free or pick one up free at a local tmo..
Thanks so far folks...

You hit the nail on the head exactly clockcycle, it's not registering. Something *in* the phone is not letting it connect, because my sim works successfully in any and every other unlocked phone I have, blackberrys, GMS world phones, the rooted Aria, but in the two "newer-released phones-- the L9 and the S2-- it doesn't work.
Phones are legit. Craigslist and brand new. Worked perfectly until calling T-Mobile for "support". The sim is fine and the goal is to keep it and not get a new one. It works.
My strong guess is that if I put a different rom that is *not* stock, the phone will work fine. It worked fine in the beginning, until I called them to address the wi-fi calling issue and they started poking around in my account, asking questions and clicking on things. I didn't want to address the wifi-calling issue too much because we could go off on a tangent.
You're right kevev, it didn't look like there was a 100% clear question. A lot of story though, to make sure there aren't 50 posts of did you do this and id you do that. A full story gives everyone the most info they need to understand the situation instead of "yo! my phone is not connecting!" which we see sometimes .
So the more clear question is:
"I am experiencing carrier settings *in* my L9 that are blocking me from connecting fully to the network on a perfectly fine sim card, how can I get around these settings and what/where are they."
I think tribalartgod understands what I'm getting at most completely. The inside-the-phone-settings. When the sim is in the phone I have bars, but when going to make a call the screen message is "emegency only". Can't try different sims in the L9 because of the need to cut the sim down. Also the L9 is not unlocked, just rooted. My guess is a de-bloatwared rom is the fix. Looking for answers from people more knowledgeable than me which is most likely all of you. Thanks again!
Craigslist, new, boxed, doesn't gurranty they aren't blacklisted.
BUT, the Aria uses a miniSim, the L9 uses a microSim. Did you cut your Sim yourself? It might be misaligned, cut wrong.
It's less than $2 to get it unlocked..
It sounds like its IMEI blocked dude. This can happen with various insurance or installment plan scams, even to brand new devices. There are options to still use the phone, but you are hosed on T-mobile. I have a blacklisted L9 because the previous owner quit paying his EIP, but it's unlocked so I used it on an AT&T MVNO connected to an AT&T MicroCell (I wanted WiFi calling too, but that won't happen with a blacklisted IMEI). Until you've gone to T-Mobile's chat support and ask the if the IMEI is clean, writing long posts in this thread is futile, and it is pretty clear everybody in this thread THINKS they know what they are talking about, but nobody has simply asked T-Mobile about the status of the IMEI, which takes two seconds.
I received my new-to-me used T-Mobile SpringBoard on Saturday. I inserted an AT&T SIM card and it asked for the unlock code. I foollishly told it to ignore this problem (I meant just for now) because I wanted to bring up the tablet fully and try it out.
I now have an alleged unlock code, but I see no way to enter it. Rebooting the SpringBoard no longer asks for the unlock code at all. How do I get the SpringBoard to ask for the unlock code again? Or how else can I enter the unlock code?
I am running the stock Android 4.0.3, which I installed via microSD card (because the OTA kept saying "update failed").
EDIT: I am now wondering whether the tablet unlocked itself when I updated to 4.0.3. If so, the question is how to persuade the tablet to start using my AT&T SIM card. When I check "Available Networks", it lists T-Mobile 3G as an unknown network, but then it lists
AT&T 3G
AT&T 2G
T-Mobile 2G
But when I try to register on AT&T 3G, I get the message "Selected network (AT&T 3G) unavailable".
Is there something else I need to do to get the tablet to use my AT&T SIM card (which has tablet service, ordinarily on a Samsung Galaxy Tab 8.9)?
EDIT2: Here is another, much more frightening possibility. When I received the Springboard on Saturday, it was on Android 3.2 and actually connecting to the Internet via T-Mobile. That is, it included a T-Mobile SIM card, and that T-Mobile was still accepting that SIM for 3G and even "4G" service. However, when I inserted an AT&T SIM, I got the expected request for an unlock code. Later that day, I upgraded the tablet to Android 4.0.3. I think that I again successfully connected to the Internet via T-Mobile, although I am not certain of that.
The next morning, the tablet was no longer connecting via T-Mobile. I presumed that T-Mobile had now officially closed the previous owner's account. I used the tablet on WiFi, patiently waiting for my unlock code to arrive. This morning (Monday), I get the unlock code, but the tablet no longer asks for it. The tablet recognizes three networks (AT&T 3G, AT&T 2G, T-Mobile 2G), but is unable to actually connect to any of them. Again, my AT&T SIM has valid service, ordinarily on a Samsung Galaxy Tab 8.9.
The frightening possibility is that the previous owner did not pay his bill, and that T-Mobile has blacklisted the tablet--not only within its own company, but even with AT&T. (T-Mobile could simply pretend that the tablet is "stolen.") Is this a real possibility?
EDIT3: Here's yet another possibility. Could the Springboard's software be out of sync with the firmware SIM lock? Perhaps the SIM is still locked, but the Springboard's software imagines that the SIM is unlocked? So the Springboard software calmly tries to connect to AT&T, but the firmware refuses?
I finally figured out some of my problem. The SIM card was inserted incorrectly! As you know, different devices accept the SIM card in different directions (notch-in-first or notch-in-last); the official T-Mobile SpringBoard User Guide does not mention or illustrate how the card is supposed to go. (The notch should go in first.) Nor does Android give any indication that the SIM card is essentially absent, except once after clearing all data.
With the AT&T SIM card properly inserted, I was still not getting a connection. I diddled with APN Names, etc.; and at one point I got a 2G connection. But when I tried to switch to 3G, I lost both 3G and 2G, and have not been able to recover either.
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.
Recently I owned an LG L70 for MetroPCS and I purchased an unlock code from an online service which worked as expected - to clarify, the unlock code I purchased was the SIM unlock code which allowed me to make use of the L70 with T-Mobile. The thing about all that was that T-Mobile owns MetroPCS and I, being out of touch for a bit, didn't realize that the MetroPCS version of the L70 is carrier or service provider locked to MetroPCS itself and wouldn't work properly even with T-Mobile which provides the network access to MetroPCS in the first place.
So, on top of having the traditional SIM network lock there's also a service provider lock on top of that, at least with the MetroPCS L70.
Now it seems this Cricket Moto E I have is exhibiting the same behavior. I purchased an unlock code yesterday after I bought the Moto E itself, got the code this morning, powered off the Moto E, inserted my typical T-Mobile SIM card, powered on the Moto E, got the code entry screen, entered the code and voila, successfully unlocked.
Now, having said that, and while I see the 4G LTE icon on the status bar it's ghosted meaning there's no data connection. I have a connection to T-Mobile, I can make calls (called customer service, etc) and that works great. But the data connection simply doesn't function at all - that's exactly the same behavior exhibited by the L70 I had for MetroPCS. After doing some research I was able to discover a method to do a provider network aka service provider unlock on the L70 using the service codes (*#*# kind of stuff which LG supports on most models, think it was *#*#2945-whatever then changing some options in a menu).
After that, the L70 worked fine with T-Mobile without any problems for data. I did also need to set the proper APN and then I set the radio info (*#*#4636#*#*) to WCDMA preferred which works best for me (and the L70 is not an LTE capable device anyway).
But now I'm stuck with this Moto E that's SIM unlocked, connects to T-Mobile in terms of phone call usage but not data. Because the Moto E doesn't support the dialer service codes I ended up using an app I purchased (SignalCheck Pro) which has some shortcuts to those hidden options (radio info) and there I set it for WDCMA preferred, then I went back to the cellular network options in Settings to set the proper APN, etc. - all this stuff is pretty much regular for most XDA users so I don't need to go into extreme details.
Having said that, it appears there's a service provider lock on this Moto E and I'm stumped as to how to get it removed. I'm guessing that there aren't different "levels" of an unlock code that Cricket would provide, i.e. one code will just remove the SIM lock so you can make use of other carrier's SIM cards and then another code which would remove the SIM lock and remove the service provider lock too.
I can't find any list of known or working Motorola dialer codes that would get me into the same kind of menu the L70 uses to remove the network lock - to be honest I can't even remember the specific steps to get it all done but it was the two-step process: SIM unlock code and then remove the service provider lock, after that I could use the T-Mobile SIM card with voice/data and no issues.
If anyone has any info, tips, or suggestions I'm all ears, figuratively speaking... at this point I can't even really sell this Moto E as "unlocked" since it apparently isn't fully functional in traditional smartphone terms. I'll keep it if I have to, of course, but it sure would be nice to figure this out even if it's just for research purposes that might help others attempting to do the same type of unlocking.
Thanks...
Just to clarify: SIM unlock was successful, but data isn't functional - did all the typical adjustments (APN correct, radio set to WCDMA preferred, phone call functionality works 100%, enabled data connection in radio info had no effect, etc) and still no active data connection will come up. Tried setting it for data roaming, still not successful. Everything works but the data connection, T-Mobile service is active without issues, same SIM card works in the L70 without issues in a straight swap.
Edit:
I have 3 T-Mobile SIMs that are active presently (don't ask) and they all exhibit the same issue of no data; they work fine for phone calls, just no data connection. The same 3 SIMs exhibited the same behavior with the LG L70 until I did that two-step process of removing the SIM lock and the service provider lock so I have no idea what to do at this point assuming that something can actually be done.
Of course I could be off my rocker and just missing something very simple here too, it's happened before.
Here's another issue that is or most likely could be related if anyone has any info about it:
Since getting the SIM unlock code for the XT1527 Cricket model I have (in my attempts to get it functional with T-Mobile, seems like a no-brainer really), I've noted that the actual cellular connection is highly unstable:
It constantly shifts from 4G LTE to HSPA+ to GSM over and over again, never really "sticking" with anything for any length of time - and of course the data isn't working at all as mentioned in the post above.
I remember in the past seeing info on some phones that just constantly won't stick on their given connection and hop all over the place but I can't recall a method to lock it down and make it stable. Not sure if the way Cricket has designed or programmed this particular device is part of it, I suppose there's really no way to know for sure at all.
Bleh... starting to not like this device nearly as much as I did just yesterday when I got it.
For the record: I've done exactly what I mentioned in the post above by accessing the radio info menu to set it for not only LTE mode, but also GSM, then WCDMA preferred, then combinations of those modes and it just will not stick on anything for more than 10-12 seconds at a time.
Very odd behavior, I may just end up using this as a Wi-Fi only device if I'm unable to resolve this crap...
Data roaming: switch to off
See if that helps

I'd be willing to bet it is an APN issue. I know you said it is correct, however I've been having data issues with mine and the APN has been the fix. Also the notes on fixes that are coming with 5.1 talk about an APN fix.
Anyway, I'd try creating a diff APN with the values you'll find in the link below, it might work

Op, another thing to try: enable OEM unlocking, settings>developer options>oem unlocking
I've done some more traveling and I'm convinced the fix is to enable OEM unlocking,
good luck
I just looked on the Cricket phone site and the Moto E (2015) LTE is now only $50. I just bought two last month at $80 each. Just my luck...
I'm in the same boat, purchased unlock code from ebay, put in tmobile sim, able to make calls but but no data. I enabled OEM unlock too but it didn't change anything.
One thing that did have some progress was adding a new APN and changing the APN protocol to IPV4/6 instead of IPV6. I was able to get 4G signal sometimes, but it still disconnects very often. Anyone else have any luck with this?
