Network Barred????

Hi there guys,
I'm a newbie to Xda and have just bought the XDA1 from a friend.
Everything works fine but i cant make any calls. Tried all types of sims.
I asked the guy i bought it from and he goes that it is "network barred".....what does that mean??
Can i un-bar it?
So far, its only good as a pda.
Anyone know what to do??
Cheers

ok, here some details i've managed to find on the phone.
ROM version: 3.14.13 ENG
ROM date: 10/09/02
Radio version: 4.08
Protocol version: 32s54
As you can see, i have no idea what they mean and have read other posts and they info on them have flown past me.
I dont have a serial cable and the phone is asking for a SID code.
HELP!!
Thanks

If you have tried all types of sim and all networks are barred then a sid code wont help you, it may unlock the phone but you still cant access the networks with a barred phone. There are 2 types of barring, the first is when a service provider locks the phone so you can use it on their network only, the second is when a phone is reported stolen, then it is barred from all networks, the phone transmits a number when switched on, even without a sim inserted, it is this number that is barred in the second scenario, the network sees the number and then closes the door so to speak.

if this is so, can the network track down the phone? or my phone number from the sim. This is cos i've had my sim in the phone and dont really fancy being nicked for doing nothing.

Check your mail box, I have sent you a pm.

If it's asking for a SID code it is just SIMlock. Which means you install the Special Edition ROM and presto.

I think he said he has tried every different sim and still gets nowhere which suggests to me it locked to a provider and also blocked from all networks, surely the phone would be open to at least one of the networks regardless of the sid lock issue.

Maybe, but if it asks for a SID code it may be locked to some obsure network or something. I'd say Special Edition ROM -> unlock first, and then figure out what's going on if that doesn't do it.

Ther you go psychy, click on the link in the previous text, "special edition rom" then click download, then run the program from your pc.

Ok guys,
downloaded the Special Edition ROM....guess what?? IT WORKS!!
thanks for the help guys....much appreciated!
Thing is, the guy i bought it from said it was "network barred"....does it mean my XDA is stolen?? If so, can i get traced? Sholud i carry on using my registered sim on it?

Psychy, if it unlocked ok and is working on a network there is no problem, what confused me is when you said you had tried all types of sim. Enjoy your phone, you can even add a cheap gps system to it and have it talk to you giving directions right to any door in uk, you can watch films, play mp3, surf the web and much more.

[Q] (Unlocked) AT&T Samsung Galaxy S4 SGH i337 gives MM#6 error for MetroPCS SIM Card

[Q] (Unlocked) AT&T Samsung Galaxy S4 SGH i337 gives MM#6 error for MetroPCS SIM Card
Hello everyone. I feel that I have a rather unique issue here.
My sister recently bought an AT&T GS4 from eBay to use here under a MetroPCS service. I took it to a local phone shop in order to have it unlocked. I am not a noob when it comes to rooting/unlocking/ROMing/etc. since I've done so and experimented with my Verizon HTC Rezound. Since I've nearly bricked my Rezound three times, I decided that I should leave it to someone more experienced.
I took it in, within 2hrs the guy had the phone unlocked for me. He put in a Simple Mobile SIM card, I called my own phone and it worked. I take it to Metro PCS to have my sisters current line transferred to a SIM card to use the GS4 with. The problem is that whenever the SIM card is put into the phone and turned on, it says Phone not allowed (MM#6). I then proceeded to look up the IMEI to see if its blacklisted. I checked online and it said that it was clean. I also went to a corporate AT&T store to have them check if it is indeed blacklisted and they said that it is clean. While at the store, I decided to look through the phone for anything unusual. After checking the Status of the phone, I find that the IMEI value is 0. I then hit the *#06# menu and get a popup which says IMEI 0/04. I let the Sales Rep know and ask him if that could be an issue and he said that whoever I took it to might have messed up with the root and that there's nothing they can do since I don't have service with them.
I thought that maybe the phone wasn't connecting to the network because it wasn't set on the GSM radio so I used the *#*#4636#*#* menu but yet nothing happens. I added the APN values for T-Mobile (works for MetroPCS) and still no luck. I even tried factory resetting the phone but whenever I add the SIM card, I keep getting the same popup. In the Service Menu (*#0011#>>Back>>Key Input: 1) UMTS Main Menu, I hit [2] Version Info >> [1] SW Version >> [1] Read IMEI >> and it says "IMEI NOT ACTIVE."
I started looking around the net to see if I can restore and/or repair the phone and I've seen YouTube videos of people unlocking the code by using the Service Menu. Currently, I'm looking around the XDA Forums to see if there is anything I can try out. I'd appreciate the help. I do not want to install any ROMs on my sister's phone unless I absolutely have to. If anything, at the moment I'm trying to flash back to stock. Does anybody know anything about this issue? Also, if I am posting in the wrong area, I apologize for the inconvenience.

You need to put the original imei back to your phone, because the guy unlock the phone for you he messed up with your phone 's imei that why after unlock the phone shows zero imei

You're not alone on this one. I bought an AT&T S3 and having the exact same issue as you are. Here's my story...LOL. I met with a gentleman at the local AT&T store. We checked the IMEI, verified it was in good standing. Since he's the original owner, I purchased the phone from him. I use my MetroPCS SIM, and I get the same "MM#6" code you described. I'm very familiar with using AT&T phones on MetroPCS. I have transferred two NOTE 2s and an S4 to Metro accounts with no issues at all. BTW...the IMEI is still in good standing & when I insert a MetroPCS SIM, the IME still shows in the AT&T S3.
My Phone specs: Samsung Galaxy S3
Carrier: AT&T
Version: Android 4.3
What I've tried:
Downgrade to 4.1.1 (Unfortunatley, bootloader can not be downgraded)
There's two things I can think of...The Android version has something to do with it. Or...I've found out that my S3 was used overseas. And since your phone was from Ebay, theres no telling how the phone was used.
My next step is to purchase a clean SIM card from MetroPCS and have transferred to my account. I'll keep you posted on my findings. For now, I'd go to AT&T store and use their SIM and see if your IMEI comes back. Or downgrade the phone if possible and start from the bottom and work your way up.

Heres my update. MetroPCS SIM card is "married" to each IMEI/PHONE. My phone in question (the ATT S3) was not correctly associated with my account. I called MetroPCS customer service (1-888-8METRO8) gave them the ATT S3 IMEI and the SIM number. within 10 minutes, the ATT S3 was up and running. I hope it helps.
Please provide feedback.

I had a similar issue with MM#6
I called MetroPCS - informed them I was receiving MM#6 error and asked them to 'activate' my phone.
Gave them my IMEI and within a few minutes, I was golden!

WORKED
Thank you for your update worked perfect...:d:d:d

[Q] region locked? sim locked?

Hey guys!
first i would like to say thank you.
i'm following this forums for a long time. I may not have anything to contribute, but i do read and learn here a lot. keep it up, you rock!
Secondly, i would like to ask for a little help, i tried to look for an answer here but i get a little confused - can't understand which problem i have:
i'm from Israel, and 2 weeks ago, i was at the US. I bought a brand new S5 from Best-Buy, and i specifically asked for an unlocked one - for use OUTSIDE the US.
and it has a verizon sim card inside (new i guess), and verizon logo on the back and as a splash screen.
when i got back to Israel, i inserted a local sim card and unfortunately - it doesn't work.
* i do get signal of my local carrier, but no cellular data can be used (wifi works fine)
* i get an error at the notifications center - that the sim card is unsupported
* i do not get the "enter unlock code" message
* at the settings-> more networks-> mobile networks ->global data roaming access menu, i get something about roaming outside the US (which might give a hint about the unlock state of the phone i think)
would be very glad to have your help, guys!
thanks a lot!
Tomer.
**** edit: i got the cellular data working (updated APN), but still have the: "Phone Activation: The SIM card is from an unknown source" message...)

Welcome to the forum.
Samsung region locks phones to discourage buying a phone for use in a different part of the world. Your phone is also intended for use with the US carrier Verizon, hence the setup message about not having activated a Verizon account.
Less soluble is your apparent intent to use this phone in Israel. You've apparently bought a 900V model which is not well suited to the frequency bands there. Samsung sells the 900F model in Israel. You would have done well with something like a US 900T, if not a 900F but the 900V model that you bought is intended for Verizon's CDMA network, not the GSM system in the middle east.
As a result you probably will have no coverage whatsoever in the 4G or LTE bands. Also, the Verizon model is one of the few that has a locked bootloader which will prevent you from using custom kernels or a conventional custom recovery.
A simple search of the forum will tell you how to resolve the Verizon error message and your other questions. Or look in my post history as I have answered these questions at length in previous threads.
It's a good habit to search the forum for an answer before posting. There is a wealth of information in existing threads and you could have easily found immediate answers to all of your questions. And remove the need for us to answer the same questions over and over. These are questions that have been asked and answered dozens of times.

Bought Second hand phone - sim network unlock pin?

Hi,
I just purchased an as new unlocked note 4 from someone on gumtree, they have been posting for years so don't think i have a dodgy phone, i sent my brother to pick the phone up from their home while i was working and he said they unlocked the password while he was there.
But i have just tried a couple of sims and i get the message " sim network unlock pin"
I have tried to contact the person but he works away off shore and don't know when he will get back or reply.
Is there a way to get by this and get my sim working?.......i was planning on rooting the phone anyway.
Thanks for any replies!

You will need to get the unlock code because it's locked to a particular network.
You can usually tell which network it's locked to because it has bloatware from that network installed.
Also in the settings on "about phone" tab it should give you some letters at the end of the firmware version which will tell you what network.
Mine was locked to O2 and I used this guy.
Gave me code in a few hours.

Hi, There does not seem to be any bloatware installed from any network....the phone does look like a bought unlocked phone. Maybe the owner has put a sim lock on the phone himself?

download the Samsung Info app from Play Store, it should tell you eveything you need to know(root wont unlock network)and no way the seller put a network lock, in terms of unlocking you'll need the code. Some service providers supply them at no fee and some at a fee, alternatively you have a plethora of online options usually at a small cost to provide code, gl.

S8 G950F wont get signal - not blacklisted IMEI: NG

hi all
i have a uk model s8 on the o2 network which was originally locked to o2.
so i took it the local market to get it unlocked which the market trader did and it accepted another uk sim
but wont connect to any network now. states emergency calls only, even with my original o2 sim.
i cant even search for any networks. when you try to search for networks by choosing the phone option, nothing happens, just states not available at this time. same thing when you try to choose manual or automatic search.
it accepts any sim now but wont connect to any network.
i thought it may have been barred even though i bought it 2nd hand and had it over 8 months so i checked imei on the net and it comes up clean. so not barred.
he couldnt also understand why you cannot search network, why this option cannot be selected.
so i come on this forum for some help, and a member did help me and got it working by flashing something to it via remote team viewer but after a few hours it stopped catching a signal because i downloaded an app onto it to hide root which worked but caused the phone to loose the signal again. and then when i contacted the member, he refused to do it again.
i pleaded with him to flash again or do whatever he did but after days of waiting without a phone he was not available to help. so please can anyone help and tell me what he did so i can fix my phone.
i know from users on here, you can have root hiding apps running on an s8 and still be able to perfom the fix to the problem on my phone.
i know it has something to do with imei not being registered on phone and it showing a NG next to imei.
any help or guidance would be appreciated
regards,
Margaret acey

don't O2 unlock phones for you free of charge? That is how it used to be when I was last in UK.
I really wouldn't trust anyone to remotely download/fix phone, they could do all sorts, hopefully you got a good guy but the fact they won't do it again seems suss to me.
Have you done this,
https://www.technobezz.com/fix-samsung-galaxymobile-network-available/
I suggest you flash stock o2 rom and take it to O2 to unlock phone, this will" clean" your phone so if the helpull member installed anything he shouldn't have it'll be wiped. Also check white o2 if your data etc has being used by someone else ie cloned your phone. (but there may be some other issue as the trader couldn't search for a network)

Thsnks for the response.
Its not locked anymore. As it accepts all sims which it didn't anymore.
This has something to do with the imei not been registered.
The imei status is NG when it should be OK.
