[Q] HELP!Nexus s locked on one provider?!?

Hello everyone...
I have a "little" problem.
In my country there is 5 providers(Tele2,BonBon,Vip,Tomato,Simpa).My Nexus s was unlocked on all of them providers.But i was installing a new rom on my Nexus s,and my VIP card(provider) was in the phone while i was doing that.When i putted a new rom,suddenly Nexus s was locked on that provider(VIP) which was inside of the phone?I tried to reinstall and installed a new rom and nothing,i cant get it to unlock on that just one provider(VIP).Phone is now unlocked on all providers(Tele2,BonBon,Tomato,Simpa),but it isn't on VIP?Did someone had a similiar problem,and could you please help me?I would be very grateful!!!

Device locking is done in the operating system, not the physical device. I have yet to see a custom ROM or ASOP to be sim locked.
Now keep in mind, the phone won't show APN's for other networks when you insert your SIM card. What is going on here is the device is reading your sim card to identify the provider then set the proper APN as default. To test if it's unlocked, try a different SIM in the device and see what happens.
Edit: I'm assuming you are talking about a SIM lock. If it's a lock of some other sort, please provide more details with EXACTLY what is going on.

Hello,first i want to thank you for your help.
My phone is unlocked for all providers except one provider(VIP).When i put (VIP) sim card,it says "emergency call only".I tried to Restore default APN,but when i press that it just says "Restoring default APN networks",after a while,it says it is completed,but still there it says"emergency call only".If i try to call anyone,it says Mobile network not available.When i go to "About Phone" menu,then "Status" it says:
Network-Unknown
Service state-Out of service
Roaming-Not roaming
Mobile network state-Disconnected
Other informations:
Model number-Nexus s
Android version-2.3.6
Baseband version-I9020AUCKF1
Build number-GRK39F
So this is it,my phone is locked to only one provider(VIP),if i put any other sim card provider(Tele2,BonBon,Tmobile...)the phone is working well,i can call anyone,text etc.Thank you in fowards...

This is NOT a sim lock. What is going on is that your phone has lost it's APN settings or is using the wrong modem. a sim lock means that your phone will only work with 1 provider, installing the SIM from a different provider will give you an error message similar to this: ‘SIM not valid’, ‘SIM locked’ or ‘SIM not accepted’
Since the phone is working on other providers, i would believe that the phone has lost it's APN settings for VIP. I would look up the APN settings for VIP and manually put them into the phone and go from there.
A quick search found a thread with the APN settings:

Good luck.

Hello again and once again thank you.I tried what you said for APN,but it didn't work.Is there anything else?!?

Try to flash another Radio. I never had luck with KF1, and quite frankly it kept me from getting any service at all for like 2-3 reboots after.
Try KD1, or KB3 (those work for me).
Reboot a few times, and see if it works.

Hi,
I am facing a similar issue. My Nexus S is running on 4.0.3 with baseband version I9023XXKI1 (Got it in UK, unable to use it in India). No matter what SIM I insert it stays in Out of service mode. Can you please suggest which Radio version I can flash to get rid of this issue? Please help!!

[Q] HTC Sensation no signal (no service) issue

Hi ,
i am facing no service issue with HTC sensation xe with audio beats i have tried custom roms and stock roms with no luck , did factory restore , i have s-off +root.
hboot version is 1.27
baseband : 11.76A.3504.00U_24A.3504.31_M
When i turn on the device without sim card it says "Please insert sim card" and when i put sim card it says limited service and no signal with cross on signal bar .
Please tell me what should i do to fix this issue also what do you think its a hardware related issue ?
One more thing .. when i insert the sim it pops up the available networks and when i try to register on network it says Your Sim card does not allow to connect this network.
Also when i put the phone in air plane mode i can change the network mode to GSM only and WCDMA but when airplane mode is off and radio is on i can't change those settings .
if i go to testing section by pressing *#*#4636#*#* and then i go to Phone settings i see there "WCDMA preffered" as the network mode and when i try to change it from dropdown list it doesn't allow me to change .
do you think if i flash some other radio/rom it will work ?
also what other thing can i do to figure out the issue .
Thanks Much .

Hi,
It seems that your radio and firmware should work for most ROMS around.
How old is your sim card?
It might be worth trying to get a new one.

No .. Sim card reader is also fine because i can still see the sim toolkit folder and when i put the sim in device it shows me a popup to select network when i try to join it fails to register on network .
also i can dial emergency numbers.
i don't think the sim card reader is broken . phone is detecting the sim but no signal .
if there is a problem with signal IC then it should not detect any network operator to choose from .. so it seems its not a hardware issue
Thanks

Hi, have you managed to fix this issue? I have exactly the same problem with a 3 week old phone!
I called HTC to let them know and they think it is a sim problem, however, my sim is very new and is working in other phones!
I don't know what to do, I needed a new phone for school and to my dismay, it is not working!!
It was working until last week and I haven't damaged the phone at all, I am very protective over it!!!
I have read stories over flashing the phone, but I worry that I will damage it if I do so, and my parents just spent a lot of money on it for me. LOL!
My sisters' and I all got the same phone, but theirs' working fine!
Please let me know if you can help me
Thank you

I think I had the same issue (as described here). While I'm not really sure which of all the tricks tried that made it work, I'd recommend trying yet another SIM. Good luck!
Edit: After all, it doesn't look like it works. My current provider claims this HAS to be related to SIM-locking.
Edit #2: Check for IMEI blocking.

Nexus 5 cellular network issue on 2G only

Hello everyone,
One month ago my device had a problem of rebooting again and again and again. . . , I give my mobile phone to service center, they said you need to change motherboard to solve rebooting problem.
But I didn't change mother board, my rebooting problem solved when I pressed power button hardly.
In service center they disassembled my phone to checkup. after then when I got my mobile phone back my new problem started.
My problem is with cellular network, my build number is MMB29K my radio is radio-hammerhead-m8974a-2.0.50.2.28 my device bootloader is unlocked. my bootloader is bootloader-hammerhead-hhz12k
My device is unable to find cellular network when I set preferred network type to 2G, my device can only find network on LTE and 3G.
I tried this different radios too radio-hammerhead-m8974a-1.0.25.0.23.img, radio-hammerhead-m8974a-2.0.50.2.26.img, radio-hammerhead-m8974a-2.0.50.2.27.img But nothing works,
This is a hardware problem?
Anyone have idea how to fix it?
Please help!!!
Sorry for my bad English.

Yes my carrier supports 2G I live in India

Hmm, possible loose connections inside the phone?

I have the same problem, im from indonesia and im using D821, after upgrade to marshmallow, my phone only have 2g, no 3g/4g. i have solved the problem.
- first i downgrade my n5 to 4.4.4
- flash modem using recovery NEXUS5_KRT16M_RADIO.zip
- Reboot your phone
- flash again modem using recovery NEXUS5_KTU84M_RADIO.zip
- reboot your phone
- go to setting, more - mobile network - APN
- reset all APN on the list than create new apn of you mobile carrier.
- and the problem solved.
nb: bootloader must unlocked
( i dont know why should flashing the modem twice, i have try only flashed NEXUS5_KTU84M_RADIO.zip from the stock of 4.4.4 but the problem still on my phone)
sorry for my bad english.

Known Issue with no service (signal)

Hi i have a nexus 5 (d 821) and i'm trying to get it work again. It has no signal with a valid sim card. i am in europe.
I tried cyanogenmod ( it shows usa, japan automatic ) but no signal.
i tried lineage the same thing.
I restore it in 6.0.1 google img ( it shows only usa band ) but no signal.
i restore in 4.4 ( it shows only usa band)but no signal.
Is this problem software or hardware?? is there any rom that can make my phone work again?
I searched through the forum and cannot find any clear solution for nexus 5
thank u

Was the phone ever dropped or dismantled and put back together?
It finds no networks at all?
Sim card works in another phone?
Tried other sim cards in the Nexus?

If this is a 2nd hand phone device and a problem with other sim cards too, I'd check if the IMEI has been blacklisted by a previous owner?

it has some falls , but i dont think this is the problem.
at *#4636 menu it shows only usa band (original nexus rom) and auto us japan band in lineage rom.
I think that the problem is in software with the radio img, or else with antenna or motherboad as hardware.
i need the opinion of an expert to deal the software part,
the sim cards works on other phones...

cant use 3g or 4g

Hi I just got a nexus 5 as a hand down and I can't use 3g or 4g I have manually changed it to 2g with *#*#4636#*#* and it works fine on 2g. And where it says select band it's usa??? Has my phone flashed with a usa ROM and will it be fixed if a flashed a UK based ROM for it the bootloader is all ready unlocked but got no PC to fastboot or flash twrp it also says on build prop that the locale is US when I can view it in ex file explorer I'm not root on 601 stock ROM

Anyone at all

Is the phone a d820 or d821?

D821 32gb variety

Very strange because the d821 is the non-USA model and should work in the UK.
It says d821 in the ROM or in fastboot? Fastboot mode will show the actual model #.

Deffos a d821 and when you go to select band it says usa?? Do you think it's been manually flashed USA ROM via fastboot as bootloader was all ready unlocked when I got it

As you can see in screen shots it does detect my sim but not 3g or 4g signal but 2g signal works fine

I've checked antenna cables and there fine so it definitely must be a software issue

Is it running a stock ROM? Does it say d821 in fastboot?
Is the imei properly displayed? Could the imei be blacklisted or blocked by the carrier?

Yes it's on stock ROM with stock recovery it is a d821 in fastboot the IMEI is displayed in settings and haven't checked blacklist any free services but if it was blacklisted 2g would not work as I can still text ring and edge data works

Just checked the Imei and device is not blacklist

Everything certainly appears to be in order.
Does the phone work properly with a different sim? The sim works properly in another phone?

Does the screenshot mean mine is a USA variety and it won't detect the uk bands hence why It states USA bands in *#*#4636#*#*

The FCC ID indicates the phone is a d821. The FCC ID for the Canada/USA version is ZNFD820.

Well I tried to flash the factory image again and the problem is still there I have even installed twrp and pure nexus and it still doesn't pick up 3g or 4g
