Have a samsung focus, rev 1.3, and running rogers firmware. It's unlocked, but it doesn't detect a network. wondering if anyone else has had issues. i didn't try it before unlocking, so idk if it worked before. i bought it used, and never tested the actual sim abilities. it displays the sim number in the about menu, and it says "emergency only" in the phone hub. it won't work with ANY sim, including rogers. in the diag menu, it does display the phone as unlocked, but it's wifi only currently. was thinking that it might be an issue with the cell radio, but i thought it was integrated on this phone. Tried diag menu reset, and full retail 7004 rom install.
it's apparently out of warranty, so if anyone has any ideas, i'd love the help!
thanks.
Has the phone been blocked? If it was second hand it may have been reported as stolen and therefore blocked for any sim usage in your country.

Did you have to unlock the phone to do that?
I called AT&T and they said that they don't have the unlock code since they don't even sell the device, but that it works on sims outside the US. She seemed to imply that it won't work on tmobile but that if I go outside the US, and just put a sim in, it will work without me having to unlock the phone in anyway.
Can anyone verify this?
Thanks

Most customer service representatives are pure idiots .... Nexus S is a Google phone , so it's factory unlocked to any SIM card you use with it(you may or may not get 3G on other networks depending on the other network 3G frequencies , and if the forgein network has 3G on 900/1900MHz it will have 3G on this Nexus S)..
Hope this helps..
Well I went to tmobile and the guy put in a sim into the phone and the phone got no reception nor did it seem to recognize the sim at all.
So it seems that it isn't unlocked.
I tried putting in this code: *#7465625#
Its supposed to tell you if the phone is unlocked or not, but nothing happens, it just says: Connection problem or invalid MMI code.
I don't need it to work on tmobile, but I do need it to work on foreign simcards. And I saw on other forums that for some people it worked on tmobile and others it didn't so there doesn't seem to be any clear answers.

you have another issue here , check your phone
Thanks for the response.
What do you mean by other issue and how should I be checking my phone?
In any case, I put in a simcard that my brother gave me which I believe is from Mozambique on a carrier Vodacom. It asked for the code of the sim when I put the phone is as always, and so I got in putting in 0000.
It then showed no connection to anything whatsoever, also as always.
Keep in mind I did have wifi on.
Then all of a sudden it asked me to update my phone and install something. So I just said yes and it updated and rebooted.
All of a sudden I have bars here and there and it recognizes that tmobile and AT&T are in the area. I also saw I think at the top of the notification bar when I pull down the notifications tab, it said Vodacom. Of course I get no reception whatsoever but that is expected, this sim was a gophone sim in Mozambique.
Does this mean that its unlocked if it is recognizing another sim, even though no confirmation of reception? I plan to try again with tmobile now and perhaps make sure I have wifi connection while doing so and leave it in for longer.
Thanks and please let me know if you have any thoughts.
what ROM you're on now?stock or costum one ? you also might consider a FULL phone wipe.because this might be caused by a difference between at&t apn or other Sim data and the other .check for that
I'm on stock 2.3 that the phone came with. Haven't messed with it at all.
So I assume you saying that if I want to switch to another sim, I should do full phone wipe then? so that the at&t apn doesn't confuse it?
IF it doesn't work with tmobile again, I will try taht, and I will also try to learn what an apn is.
Thanks for the help.
Might work or might not !!! backup all your data and apps first then use the shotgun method lol
But what I am sure of is that Nexus S phones are always unlocked and SIM free..
Hi all,
I've just moved to Spain, and I'm having trouble using my phone (Nexus 4) and my girlfriend's (Moto G) on a Spanish network - we have pay as you go SIMs from Euskaltel.
I can't for the life of me work out why we're having problems - both phones were unlocked back in the UK and I've successfully used a number of UK SIMs (again on both phones).
There are several "symptoms" I'm seeing:
1. Every time I restart the phone with the Euskaltel SIM inside, I have to enter the SIM PIN code. This seems unusual.
2. When I went on IMEI.info to check whether the phone really was unlocked, it lists the Network as UKG and the Carrier as UNITED KINGDOM_OPEN. I wonder if somehow our phones are only unlocked for UK carriers? I didn't realise this was possible, but if it is, how would I remedy it?!
3. When I try and download the Euskaltel app from Google Play, I'm told that it is incompatible with my devices. Perhaps caused by the previous problem?
4. I can make emergency calls, so it's not a connection problem but rather a registration issue.
I'd be very grateful if anyone can shed some light on this!
Many thanks.
Is it possible to fully unlock this phone?
I bought it on Ebay from a koreran seller.
It has an Alleh logo on the back and on start-up.
It is supposed to be fully unlocked, but it`s not.
When I turn on the phone with my main sim it gives an error message and network is blocked.
I know it is partly unlocked because I can use it with my other sim, but the reception of this network is pretty bad where I live.
So I really want it to work with my main carrier.
It is rooted.
Hey M8 crew!
New to the M8, just bought the phone from swappa. Apparently it has root/s-off/some lollipop build installed on it. Clean ESN.
Took it into verizon to activate it on my line, but the sim doesn't appear to activate as they expect. It detects that it was inserted, says to reboot, after reboot still says no service, and never performs any activation. Verizon rep was claiming that the rom was causing the failures, and it does appear to likely be software related if it is never launching the activation. VZW tech support was no help other than saying it may take up to 12 hours to activate the sim (bs meter going off). Spent 2 hours in the store trying to get it to activate, saying everything was fine on their end. Tried a couple sims in store to rule out a bad sim. Have even tried the tape on the sim trick to see if that might have something to do with it.
Has anyone ever seen / heard of this sort of situation before and have any idea of how to fix it?
Would a stock RUU flash help out in anyway?
Is it because it is not a verizon rom that the activation is not happening? Would I somehow be able to use a different verizon phone to activate the sim, then put it in my phone and have service start working?
Any ideas?

If the phone was used on another carrier it might be stuck in a non lte/CDMA mode. Flash stock vzw ruu. Do a factory reset. Go into mobile settings and make sure it's set to global. Then see if default network is set to vzw. Then check provisioning.
That did it. Thanks!

Np...bought an m8 for my dad a couple months back and same thing happened. I finally realized it was used on a different carrier.
Hi. I got my s22 ultra sm-s908e unlocked two weeks ago through Amazon. Everything was working fine until today when I realized I couldn't make any calls in the morning. I saw that on the lock screen on top it said network locked emergency calls only. I rebooted my phone and it got into the network again. But around ten minutes later it got back into network locked.
I have tried almost everything. Cleaning my sim card, resetting network settings, even re applying the network configuration message. Nothing.
The only thing I have done to it was flashing the XSG firmware since it was the latest one and in my country (mexico) the unlocked versions usually get updates really slowly.
Tomorrow I'm going to try to do a factory reset but I'm asking first to see if I ****rd up something or if my phone was locked somehow.
Hopefully somone can help me.
Just a suggestion: reflash original firmware for your device and see if it remains locked. Also check current lock status in settings --> Connections --> More Connection settings --> Network Unlock
There is PERMANENT UNLOCK and TEMPORARY UNLOCK. you may have been sold a phone that was not fully unlocked.
Flash original firmware and contact amazon customer service, advise that after updating and doing factory reset the phone appears locked, get a replacement or a refund.
S908E here, USA user, AT&T customer...
They locked my sim card out right after popping it in. Called AT&T and they said the phone is not on their supported list. Only U and U1 models. But they unlocked the sim card for me. This only affects my number, not the others on the same plan. So check your carrier if they also have such a list.
