[Q] can't connect to mobile network - Galaxy S 5 Q&A, Help & Troubleshooting

Hi I purchased an s5 that was a few days old 2nd hand. I checked everything out on check mend and everything was fine, few days after purchase, phone will not connect to my network or the 02 network with any Sim. I spoke to 02 and they tell me the phone is not blocked or stolen. I also got a receipt from the guy I bought it from, but like I say it worked fine for a few days then this happened and now nothing. I managed to reg the phone with Samsung, although I do not know if I can get away with a warranty repair, as I am the 2nd to own it, even though it really was new when I purchased it. Anyway, any help would be Greatly appreciated.

The provided info was not enough to investigate the cause of the problem.
What you have done or installed or changed in these few days

Forgive me, I am new to this.
I have tried both 02 sim and a giff gaff(my provider) sim in the handset and nothing works. I am going to pick up another sim this morning to test that also(different carrier). Both Sims i have already tried work in other phones fine. The giff gaff sim when I put it into my daughters s3, works perfectly and calls can be made and received.
I was considering flashing another stock ROM just to eliminate software, I have opened a support ticket with giff gaff, who have said the sim is fully active.
Just trying to add bits that are useful here, the imei of the phone is fine and shows up as being there and not null, everything else on the phone seems fine also in terms of usage, I did have mobile data, which for some reason I can't seem to get now, but I did re write the APN, so will re put it to the original. Just won't register on network.
Anything I have missed or you need please ask. I am a noob, although I have flashed a few ROMs without issue after lots of reading. Should also add, the phone is completely stock, nothing messed with in any way. Sm-g900f. Xxu1ang2.
Thanks in advance.

Enter the code *#0011# and check the last line, IMEI CERT = PASS or something else?
APN is not required at this step (register to the network).

Hi, that code brings me am error" not registered on network" although I now have a data connection again on 02 and am at least getting 3 bars on the analogue signal, just not registering. I have just put in a Vodafone sim, which it recognises as it pop s up and allows me to select Vodafone pay as you go, but still does not register. Icon Just keeps spinning.
***********************UPDATE******************8
I just ran that code with the vodafone sim, it produced this exactly.

1- Is your phone rooted?
2- Enter *#2263# (*#BAND#) and see which option is currently selected?
3- Enter *#7465625# (*#SIMLOCK#) to check for the lock status?

8- The pre final step is factory reset your device

Hi,the phone is not rooted, those codes you gave give "not registered on network", i have factory reset the device a couple of times now.It is actually my daughters phone and was working fine, she turned it off whilst at college and then turned it on and it seemed to not allow calls and texts from then after about a weeks use, 5-7 days.

Since you have factory reset and it does not help, try to relash the stock frimware.
Install Phone INFO ★Samsung★ app, go to the Menu 'Firmware Browser' to download the desire firmware, and flash using Kies or Odin.

Hi, thanks for responding so quickly, that was my next move in all honesty, just seems weird. so there is nothing that stands out in the quote? my wife also has an s5 and where the quote from the first code given, hers said "available" where mine states limited., just thought i would add that incase it meant something.
Thanks for all the help.:good:
sorry for the delay, it would not let me reply to the other post as i am junior and there was a link in it, so i had to respond this way, excellent app by the way, many thanks for linking it. I am going to have to thank you, i do not know how, but i will have a search, you have been most helpful.

STOLEN
***************************************** U P D A T E *************************************************
I just ran another check mend report, after being told it was not blocked by 02, it now appears that it has been blocked and reported as lost / stolen.
Anyone any ideas on where to go with this?
I have receipt, 2 check mend reports, 1 clear and 1 not, clearly an insurance swindle going on, phone companies not interested
Thanks in advance.

NOTE 3 not picking up 3G signal.

hi everyone,
It's my first time i post on this forum, i am a noob.
In brief i just brought an GALAXY NOTE 3 (SM-N9005) a week ago from a seller but just yesterday i realized that my phone work only on GSM and can t pick up 3G signal at all even if i am in a area where there is cover. i searched the net hours and hours but didn t find a clear answer.
Please can someone figure out what is the problem and how to fix it.
Here are my information:
I am from Morocco,my operator is MEDITEL(i tried others operators here "INWI" and "IAM" it doesn t work either no 3G signal ), my Note 3 is under KitKat 4.4.2,
For more information about the phone look at the screenshots in the attachement.
The phone is STOCK not ROOTED i didn t mess anything yet.
The phone is from Spain and the carrier is Orange because at boot the is the orange boot logo.
It will be soo nice if anybody can help me. I really like my phone but if it doesn t work like it should its a shame. Here in morocco high end smartphones are expensive and no warranty unless you buy it from from samsung store where is more expensive.
Did you enter the APN settings?

Yes it might be the problem with CSC, but:
- Did you try your SIM card with another smartphone and have success with the 3G connection?
- In the Phone INFO *Samsung* app, enter the Menu and select [Note 3] Fake Detector, tell me what does it say? What is the Diag Code?

1- This error related to my app. I will fix it soon. Sorry about that.
2- There is a big chance that your phone is a refurbished one. Because it has NONE manufacturing date, and the IMEI does not match with the one on the label.
Can you PM me full info from the Phone INFO app?
---------- Post added at 07:13 PM ---------- Previous post was at 06:26 PM ----------
I have looked at your screenshots you sent me.
Your device doesnt have manufacturing date and hardware revision info, so the big chance is that your phone is a refurbished one.
If you can return it to the shop where you bought, I think it is the best choice for you now.
Sorry to say about that.

I called the seller and he told me to bring back the phone so he can find what is the problem. For returning the phone i don t think he will accept, firstly ther is no warranty and secondly the phone was sealed with samsung,he didn t open the box then its not he's fault.
If he didn't fix it i will just live without 3G
Thanks a lot vndnguyen and sorry for wasting your time. Btw flashing another modem (CSC) wouldn't fix it?

can you please be more specific. You can use only 3/4G no 2G?or what?

Hi!
I have same problem.
I Live in Finland. 3 month I used DNA operator, was all perfect. Now I connect to Sonera and work only 2G connection.
I flashed 3 different ROM, flashed 2 different modem ROM, finally I flashed 4 files Poland ROM and use it like it is.
2G worked propertly, 3G don't connect.:crying:
Mobile broadband work correct at all settings.
Can't find way out...

Unlocking Note 3 in Canada, Switching from Verizon Network to Fido.

Hello XDA, I have been trying to find the best phone for the money and I finally found it!
I have the following:
Galaxy Note 3 Model number: SM-N900V
Baseband version: N900VVRUEOB6
I know how to get my IMEI and other information if needed.
I have a fido account that I want to use with this phone, I checked network compatibility between the phone's specs:
(searched phone on gsmarena)
and I compared it to Fido's network specs:
(searched Unlocking on Fido's website)
It seems the networks are compatible, which is great. The error I get when I attempt to use the phone is this:
"SIM card is not from Verizon" notification pops up,
I'm really trying not to waste people's time helping me with this, but this is my first time with this device and I could really use help making sure this is unlocked. I bought the phone here:
(amazon . ca website searched note 3, went to cellcow seller got phone for 230$ advertised as "unlocked")
They claimed the phone was unlocked....
The calling function and texting works fine with my Fido SIM
I cannot use any data from the Fido SIM.
I've emailed the seller, and I'm trying to speak with them to get it working, I checked another forum which said to enter a string of digits into the dialer to unlock the phone, which didn't work. What do you suggest I do to try and get the data functioning properly on the phone?
unfortunately I'm a new user and cannot upload photos or put urls or anything but I can answer as many questions as needed

vs995 ¨not sim card inserted¨ got it from ebay seller: guarantee cellular

I would like to know if someone could help me, i got a V20 VS995
I bought a cell phone that is supposed to be unlocked and when I put the sim card, it does not recognize it, I tried with 4 sim cards and it does not recognizes it, it always get the same message ´sim card not inserted´
the ebay seller told me to reset the phone and also reset the network settings, and switch the phone from global to lte / gsm / umts, and this does not work either. the phone also does not let you save a new apn, the apn list is empty and there is no way you can add a new apn.
and so, I updated the phone to the latest version and the same message keeps appearing... ´sim card not inserted´so I downgrade the firmware 2 times (stock) and at this moment it has the first firmware again:
VS99512A
B16.LGE.VS995.0
COMPILATION NUMBER
NRD90M
I also try the app
hiddenmenucall and when selecting the option lg hidden menu or OIT hidden menu the application closes (does not work)
I am not root
What else can I do?

Seller does not have to respond, call paypal and say the item is not as advertised and you got something different. You are protected up to 180 days with paypal, file a claim with them. But if you bought the phone, stated: broken parts or not working, paypal will not return your money. As you have been warned that its not working and you buying the phone as is. The only thing to do at this point is try paypal, if that does not work, file a chargeback with your credit card company. Keep in mind, that if you do that, you need to provide proof and details and transactions and may take few months or so to resolve. They will give you the credit in the meantime, but if they find out, its not a valid reason they will take back your credit until the investigation is complete.

Any insight on what changed config to b16.leg***? I can't find any info on it and I have two v20 vs995's stuck on b16. Both were rooted and working great until I flashed a firmware update from androidfilehost. Lost root and recovery access on both. Any help would be appreciated.

Phone Not Allowed - UK SM-G950F

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?
Sent from my SM-G950F using Tapatalk
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.

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.
