Hello everybody!
I have a Galaxy S4 (GT-i9505) which shows "No network service", even though I almost always can access internet. However I can't make calls or send text messages. I just realized it shows IMEI 0/01 when i dial *#06#. The device status says official, but I can't update the phone (currently on android 4.2.2). When I try to do it trough Kies it says that the firmware isn't supported. Does this mean the previous owner has flashed the phone? The problem with calling and texting only seems to appear with some carriers.
I don't want to void the warranty if it isn't already and I have no experience of flashing phones at all, so I'd prefer to fix it without doing that! Does anybody know if it's possible? The phone is unlocked and is first bought from Telenor in Sweden (in case that makes any difference).
This happened for bad unlocking. The solution now is bring it to Samsung Service Center or Service Tecnic Assistant. Good luck :highfive:

My i9500 was working fine for couple days then I didn't know what happen it keep saying no service.
I tried to reboot it and that is when the phone lost all the Samsung software.
The phone still can be used as a tablet with the WIFi connection with all the apps, but no samsung start up.
I called the software service at Samsung US because the phone is still in the one year warranty, They said the phone was not made to be used or sold in the US even that it was made in Korea by Samsung and its a GSM phone. The only way I can get the phone back to original start up they said is either to ship it to Korea, North African countries or to any of the Mideast countries to Samsung device service.
any fix?
Do you have a rooted phone? I dont know if this is a case on i9500 too, but previous devices could "lost" IMEI number (corrupted or deleted EFS folder) and phone lost connection to a mobile network. Can you see your IMEI number in status menu?
Hello,
I recently bought a S5 in the netherlands (i live and use the phone in belgium). Started it up, everything works fine. I make one phonecall as required for the regionlock, works fine.
Then something strange happens, after the one phonecall required, i cant accept or make phonecalls anymore.
I get a message "your phone has been locked due to security reasons"
Now the weird thing is, if i use a simcard from another carrier, the phone just works fine, no locking whatsoever...
Called Samsung support, told the story, they tell me phone is region locked and i need to get a code, but the phone never asks me for a code nor can i put one in anywhere.
So i called my provider, they tell me the phone is blacklisted probably but they cant check that...
After some research i found out the phone is actualy from UK with an international firmware on it: G900FXXU1ANG2 (countrycode BTU)
Anyone have an idea how to get rid of this problem?
I dont want to root the phone just yet in case i have to exchange it for another one.
Would it help to get the countryspecific stock firmware installed for my country? (Belgium)
thanks a lot for the help

You'd get better help if you gave us more details, notably verbatim error messages, rather than paraphrasing.
Your provider can certainly tell you if your phone is blacklisted since an IMEI blacklist is under their direct control. So ask them again to clarify that. Region locking is much more likely though. Samsung region locks phones to prevent grey market sales, which is exactly what you've tried to do. The region lock is released after you use the phone a short while with a provider in the original region, which sounds like the UK in your case. Region locking is also a type of blacklist, although that term is almost always used to refer to carrier IMEI blacklisting unless otherwise specified.
As you didn't make any preliminary calls in the UK, nor apparently did the previous owner (or vendor), the phone is now restricted. You could travel to the UK and use your phone there for a day to dissipate the region lock. Or a lot of people claim that a regular SIM unlock code, such as you can buy on Ebay or any number of other places will also remove the region lock (unconfirmed). Or you can root your phone and circumvent the region lock by editing the blocked regions in your customer.xml file.
There are lots of existing threads on this subject, as you would know if had you done a search. Refer to those for further elaboration or you can search my post history as I've posted in detail how to remove the region lock in previous posts.

Thanks for the reply, this forum was my last resort since i didnt understand the problem.
I dont get any error messages at all.
provider A in S5 --> while calling i get the message phone blocked for security reason
provider A in S4 mini --> works perfectly
Provider B in S5 --> works perfectly
so i thought problems lies with faulty simcard, exchanged it but problem stays
when i call samsung they tell me its a provider problem
when i call my provider they say its a phone problem
in europe shouldnt matter realy where you buy your phone since there's free traffic of goods and services. I wonder if the webshop knows they are selling UK phones, ill talk to them about it tomorrow.
thanks again for the reply ill try to get the problem sorted, if that doesnt work at all, i guess ill just root it and fix the problem
kind regards,
thale
Humh, sounds weird.
Use the code *#7465625# (*#SIMLOCK#) to check for the lock status. On some devices this code needs root to launch.

If I understood you correctly, your SIM card works properly in other phones. So your SIM card shouldn't be the issue. If your S5 is SIM unlocked (carrier unlocked), you could try someone else's SIM card in your S5 to rule out less common problems e.g. bent SIM socket.
And regardless, in your place, I'd open a support ticket with your provider. That should cover anything like a IMEI blacklist. All in all though it does sound like region locking. Which is Samsung blocking a phone from being used in a different region unless it has been first activated (i.e. used for a few calls) in the original region first. I wouldn't think that a region lock between two parts of Europe would be intentional, but it is still something to look into.
Without any explicit error messages, it is difficult to narrow down the cause. You might consider installing a logcat app to capture the system log which may have more information about the error.
Also try dialing *#06* and ensure that you have a valid IMEI (not all zeros)
And dial *#0011#. You should see a (IMEI) certificate "Pass"if at the end. If it says IMEI CERTI: FAIL or NA you may have a flash error or IMEI blacklist.

Hello,

Try to use Provider A with another sim card?
Sent from my SM-N9005 using Tapatalk
Had another talk with the helpdesk from the provider, they told me the phone is blacklisted but couldnt give me a reason why.
Im only blacklisted with provider A, if u use the phone with another simcard from another provider it works like a charm.
Ive had to send them my proof of purchase, and they will unblock the phone...
Havent had any feedback yet from the shop i bought it from, so maybe they can shine a new light on the whole deal!
Try
How about contacting the retailer? I think you'd better not root the phone or fix it by yourself.
Hello everybody
Recently received a Samsung Galaxy S5 originally from Verizon. The Phone works really well Outstanding performance ! but it has no service. Explanatio: I live in Cuba here the cellular operator is Cubacell operates on GSM. The phone finds the signal and notifies in "avaliable networks" tha Cubacel is Available... But fails registering on the network, and i don't know what to do... many technicians already "diagnose" the phone and most of them says is a problem qith QCN file, but what really worries me most is that Board IMEI is not the same the cell shows on *#06# .. so i found all these really tricky since i'm new in Android cause my previous phone was an HTC Windows Phone 8x that suddenly died and revived with no service either (a strange case for other post i hope) The S5 is SiM unlocked everybody says, besides every verizon phone is gsm unlocked by default don't they? The dark story of it is that the phone was previously unlocked for use in another company in the US and was working there perfectly. Right now the phone is running Lollipop, and no problems with WiFi restriction for Cuba so far... Registered on Samsung, on chat they send me to verizon saying phone is locked but i don't think thats the real problem...
So i'm wondering if anybody could help .... since in my country everything is so hard to get ja! and the acces to Octoplus Box or Z3X is expensive.. very...
Phone Details:
Model SM-G900V Android 5.0 Baseband G900VVRU2BOK3
Kernel 3.4.0 Build LRX21T.G900VVRU2BOK3 Hardware G900V.00
Security MDF v1.1 release 4 VPN v1.4 release 4.1
KNOX 2.3 Configuration J13.SAM.SMG900V.1
Thanks a million in advance and greetings from Cuba...
Hey guys, I'm having an issue that I can't seem to resolve on my own. I recently broke the screen on my Note 5 so I decided to use my old Note 4 until the Note 8 comes out. Today I took out the phone, placed my simcard into it and started it up. I thought everything was fine until I tried making a call where it just gives me a pop up notification that I'm not registered on the network.
The phone isn't locked, bought it new unlocked. No custom roms (ever), IMEI is correct (naturally). So far I've reset the phone to factory settings to see if that would help to no avail.
If manually choose a carrier manually (both searching and choosing one takes longer than usual) I get a new message "No Service Selected Network (Telia N) not available".
The phone worked prior to me putting it away, my sim card works in other phones. Any suggestions or am I up sh**s creek without a paddle?
take out the simcard and try an emergency call (in my country it's a crime to playing with it. But without the card nobody can catch you.)
if the message appears again = it seems HW related problem
if the emergency call is working = it seems your phone restricted by the carrier and you need to ask the customer service why. Maybe a mistake
Thanks, it appears to work without sim card dialling 112. I'll email and call my service provider tomorrow.
Hi All
I'm at my wits end with this Samsung S8 phone, Bought a 2nd hand S8, was working fine, but I noticed the internal storage was only showing 9.63GB
Had a look on here and the solution was to stock flash the phone. I did that, all fine, storage was back to normal....BUT since then I can't make or receive any calls.
I get the error "phone not allowed" and it won't connect to ANY mobile network.
I've tried loads of different suggestions
Sim is OK in another phone
Re Flashed (numerous times)
Andriod 7 and 8
Sim and Phone OK with three network
But still have the issue....
Can anyone help me? or push me in the right direction?
Cheers
Tommy
You probably tried this, but try booting into safe mode. If it works then there is a software problem. If the problems persist in safe mode you probably gotta contact Samsung.
Are you sure the phone is unlocked?

Is the phone blacklisted? if it is blacklisted then it will not connect to service. Your SIM wil work perfect in any other phone.
Hate to say this but it does sound like your phone has been blacklisted.
You can check with one of the online IMEI blacklists.
If your phone shows Phone not allowed and a code like MM#6, it usually is an indication that it was blacklisted.
Check your phone's IMEI on a blacklist checker like http://imeipro.info/
The previous user most likely had the firmware and baseband messed around with and once you flashed stock it reverted to true state, it's highly advised to get back in contact with the person, where was the phone bought? A shop? Online?

Yeah tried that , still the same
If one is in possesion of a S8 that says "Phone not allowed", and the phone is blacklisted, is there any way of fixing that?
I have the same issue here..
I bought an S8 from Manchester last summer, and I started using it last week, (because my other phone worked longer than expected) and after I gave the phone the Network key that the previous user wrote down for me, then that message appeared.
So im stuck with this almost completely new brick aswell...
Any options at all?

The only real solution here is to either go abroad and sell the phone, or sell it to someone who is going abroad. The phone will work outside of the UK.
It does sound as your phones imei Nr is blocked in UK.. Probably the person who sold you the phone, stole it somewhere.
I have the same problem on my Samsung S7 now in Brazil.
In Canada, on Canadian carriers, everything is fine, and if I put the Canadian SIM in there everything is fine. But the minute I plug in Brazilian SIM card, boom, Phone Not Allowed message comes up and it won't connect to any of the Brazilian networks. Brand new SIM, works just fine on another LG phone (and any other phone I tried).
The phone is unlocked, I even checked with a few pieces of software and there is no network lock on it either.
I've got the master & network unlock codes from Samsung, but have no way of inputting them as no prompts for those come up when I insert the Brazilian SIM.
I checked the IMEI, it is definitely clean and not blacklisted.
Heck, I even rooted the phone to see if that would help, and still nothing.
Any idea what else to try or what else might be causing this goddamn message to pop up?!
I solved my S8.
Blacklisted on all uk networks except Three network.
Works perfect.
