Hi All,
I'm at a loss, would be tremendously grateful if anyone could help me save my galaxy:
- My phone is an 850F, purchased sim-free from Carphone Warehouse in the UK. It is rooted.
- Recently I inserted a new sim card. The phone worked perfectly well for a week.
- Upon rebooting yesterday, the phone awoke to a message stating the sim was locked and prompted me to enter a code.
- The phone could no longer utilise the network.
To troubleshoot:
a. I inserted the sim in another phone - the sim worked fine in this other phone.
b. I tried 2 other sims for different countries in my 850F (O2 UK, T-Mobile US) - both of these sims seemed to work fine.
c. I tried a friend's sim in my phone (on the same network as my problematic sim) - it also didn't work.
d. I contacted the network of the new sim, they suggested I try 2 different 4 digit unlock codes - both failed.
e. I received a new sim from the same network - using it presents the same error message and prompt to unlock the sim.
f. Finally I wiped the phone, re-rooted and installed a new rom (Cyanogen 12).
- This has not solved the problem. In Cyanogen I receive the message: "Phone is Perso Locked". Again I am prompted to enter a code.
Thanks for reading, any help or suggestions would be immense!
Cheers,
Tal

Hi. I bought an s3 for my wife .
The phone was unbranded and. She was using TescoMobile until 4 days ago when she lost signal coverage.
We swapped the sim card from Three network and everything was working.
The next day we went to Tesco to get another sim card to test and nothing happened. The phone picks up the internet signal but we receive a message "your sim card is not allowed to connect to this network".
We went to Meteor shop - this same not allowed, O2 this same, Vodafone is working.
I installed the 4.1 Android to see if it works. The same happened. I unlocked the phone to see, but the same, only two networks are working with the phone.
What do you think has happened with the phone ?
Phone is going to Samsung for the warranty repair on Tuesday.
If the phone works properly with a different SIM then it's the SIM/network problem.

Hi,
So where is the issue? I rooted the phone, unlocked, changed the ics to jellybean and the same issue arises.
In Ireland there are the following network providers:
1) Tesco mobile (using o2 network) - sim was working for few months and stopped.
2) O2 - their sim cards are not working
3) Vodafone - sim is working fine
4) Meteor - sim is not working
5) Three - sim is working fine
6) Emobile - not checked.

One JB test leaked build will not fix a problem .
3 Sims work fine and rule out a phone problem .
Do the two non working sims work in other phones in the same location .
Possible you have faulty network settings /APN .
I would say back up data and try a factory reset first except you now have non Samsung firmware on the phone .
That voids warranty so you will need to remove it before returning .
your sim card is not allowed to connect to this network".
Not allowed possibly phone blocked IMEI .

I was talking with Tesco Mobile - IMEI is not blocked on their network.
Original software 4.0.4 have this same issue. APN setting are ok - checked with the HTC Wildfire also with Tescomobile.
Repair company said that they don't care if is custom rom, they will put back the original software and start testing the phone, everything under warranty.
Once i went to friend who bought a S3 from Tesco mobile and i his sim card is not allowed to connect on my wife phone. Wife sim car is connecting to the internet but to network
Hello,
I purchased a Samsung Galaxy S4 I337 off someone online and went on ebay to get the unlock code for it. The phone was initially locked to Telus (Canada). I put in my Bell simcard and it worked great, until three days ago. I tried making a call and it received the message, "Not Registered on Network".
I did all basic troubleshooting:
- took the battery out and put it back in
- factory reset the phone
- tried different simcards
- got a NEW simcard
- tested my simcard in another phones and it worked fine
- I even ROOTED MY PHONE!
- I tried the *#0011# unlock but it doesn't bring me to the full debug screen
I really don't know what to do any hope there's someone out there who can help.

Hello all,
It has been awhile since I've been on here. I apologize if I am posting in the wrong section (this forum has changed so much over the years).
Anyways, I am currently a T-Mo customer and just got a Metro PCS Samsung Galaxy SGH-M819N because I thought I could simply flash a rom that would allow me to use T-Mobile sim card. However, it turns out that it may not be that simple.
Can someone advise whether or not I am able to unlock the sim (without paying it through sites such cellunlocker.net) via flash? If so, would you be kind to direct me to the site or page which gives directions?
Thanks,

oK, i paid
4update:
I am ended buying an unlock code via eBay for $14.99. I enter the code and the phone no longer asks for SIM unlock code BUT now it does not register with any carriers.
i inserted my t-mo sim card into the phone, go to settings, and tried to automatically and manually connect to the tmobile network but keep getting the "unable to connect at this time. try again later" message.
i contacted tmobile via chat and provided imei number and sim card number but was still unable to connect.
i flash backed to stock firmware 4.4.4 and still no luck.
i checked my "device info" and under "phone status" it shows my phone number assigned to the sim card but not connecting to service provider.
Any ideas anyone? Please help.

I am able to connect with the stock Metro PCS apn.
I am also able to use TMO apn as well.
Make sure the apn is correct.
Go to more networks and then mobile network.
Been trying to get this sorted for my kid, any help is appreciated as it was a bday gift and its been early 3 weeks
used tmob G530-T
rooted
RR ROM / Nougat [ROM][7.1.2_r17]Resurrection Remix-N 5.8.3 For Grand Prime[OFFICIAL][G530H-W-T-T1-FZ]
unlocked via doctorSIM (accepts code)
testing w my ATT sim
2 issues.
1. on every reboot prompts for sim unlock code via generic dialog box
2. no cellular service - via chat ATT activated the existing SIM w IMEI of new phone and existing sim. Went to APN area in settings and tried to manually enter ATT settings but after save said 'customization not available for this user'. Have not tried the Wifi first trick but I can enter a new APN but settings does not stick.
Assume the sim setting would be auto configured. using the select network provider it cannot activate on ATT (my ATT sim on a work account)
try a different rom or the unlock code is bad?
TIA
anyone?
Hi all,
I have a Huawei Mate 2 from Freedom (Wind) Mobile. I have updated it to Lollipop 5.1 by unlocking the bootloader. In fact I made a guide for it a while back.
https://forum.xda-developers.com/ascend-mate2/general/guide-step-step-wind-mobile-canada-t3387490
Recently in Canada the cellular service providers are forced by law to give us an unlock code for free. After unlocking the phone would work with any service provider. This phone has a pretty big battery and would be ideal for a travel or backup phone.
I successfully got an unlock code from Freedom (which was pretty easy). I then put in sim cards from another provider (Koodo, Fido, etc). However the screen for me to enter the unlock code never popped up. It just say "no service".
I tried to manually set it up, by clicking the notification. "No Service: Selected network (Telus 3G) unavailable". However it won't register. Neither did the unlock code entering screen ever pop up.
And under data settings it say no SIM card. However the phone works perfectly when I insert my Freedom SIM card. But when a foreign SIM card was inserted it just say no SIM.
My question is has anyone been able to unlock this phone under Lollipop 5.1? How did you get to the "Enter Unlock Code" screen?
I also wonder if anyone has any luck unlocking with the original Android 4.3. If someone did, maybe I should flash the phone back to its original OS.
Thanks in advance!
