No Service- HELP!!!

I bought new TyTN II, and when I insert my sim card, he doesn't recognize it, in the top of the screen is text NO SERVICE. In the start/settings/connesctions/connection setup, there is no my country to select, or my operater. Does the new cooked ROM may solve my problem? Please help...

Does it say no sim card, or just no service. If it doesn't recognize the sim card. then it is probably sim locked. If it recognizes the sim card, but just offers no service, it could just be your connection settings.

Do as this thread goes it will do all you need
http://forum.xda-developers.com/showthread.php?t=433835

Hello,
I didn't want to start a new thread, because this one is somehow connected with my problem
So here it is:
I've been using my phone for about a month, it used to show full network ect. My friend gave me an anthenna for gsm mobiles (well, sometimes it didnt work properly when I was in the basement i.e.) so i tried it. Worked perfectly, except it was sticking out. So i thought that I don't want to use it and disconected it. Since then it shows no service, sometimes "1 dot" in network display. Tried hard reset - didn't work. When i put the anthenna back, it shows full network again.
Please, tell me, what should I try.
Thank you in advance

I seem to recall reading somewhere here that once you put in an external antenna, something gets tripped and the phone will only work with an external antenna from that point on.
Sorry -- don't recall any details. Try searching.

[Q] Voice: Out of service / Data: In service HELP!

I have lurked so much around XDA and still I have no solution
I own a Moto X XT1053 on Movistar (Mexico)
Everything was working fine until I got my SIM card replaced. Now Voice and SMS don't seem to function but Data from my carrier works fine.
When I try to dial I get a "Mobile network not available"
I have done "fastboot oem config carrier (all possible options) No luck.
I have switched from 4G to Edge since that seems to be the solution for many but that didn't work for me.
Yes I have searched for networks and selected "Choose Automatically" No luck.
I have flashed back to stock firmware using T-Mobile's firmware (which has always been my solution and everything worked flawlessly) but now that doesn't work. I've actually not a fan of custom roms I only do stock and xposed the [email protected]#$! out of it but even a clean stock doesn't seem to fix it.
I even went to Movistar and they believe its my phone since they tested my sim on another phone and voice worked on theirs.
Any thoughts on what could be the solution? Please Help!

Check the APNs?

I think your first statement supersedes your latter statement and everything in between. Just because your new SIM worked properly in another phone doesn't mean it's guaranteed to work in your moto x. Maybe for some reason your moto x is reading the sim as a data only Sim, or maybe it's registering on the network as a data only Sim.
did you cut the Sim to nano or did it come as nano?
Did you try a different SIM in your Moto X?

They did try another Sim on my phone and same, no good. Voice seemed to work on other phones. I personally believe my phone was blacklisted. When I went to get my Sim changed I forgot to mention the account was under my moms name. Now my new Sim is under my name but with the number of another owner (my mom). Which could explain why I get no voice or SMS but data works fine. I am actually on my way to customer service right now.

Well just returned from customer service. No good. Its the phone itself. :/

Have you solved the problem? I'm using Samsung Galaxy S5 and has similar problem... After couple of times of change rom the problem occur... I'm not genius and I have struggle with this problem for more than 2 weeks... See whether we can work this out...
My situation is:
1. Voice: out of service, data: inservice;
2. IMEI: seems normal
3. I tried two SIM card with different ISP, neither work;
4. I also try that two SIM card on my iphone4, both work well.
5. Since my phone is G900F HK version, and I'm currently in UK, so I tried latest UK stock firmware and latest HK stock firmware. Same...
I had do some searching and said that there are few reason that might lead to this problem:
1. IMEI error. Flash rom may damage your partition, if your IMEI is 0046*** or 0000*** something then this is the case;
2. Baseband related. Just flash some wired rom that no capable with your local bands?
3. still looking...
Good luck then...

Same thing
Did you ever solve this? I am having the same problem on my Moto x Pure 2015.

Question Help me fix it

Hello guys. I bought a s21 ultra 9980 512gb.
However, i cant use it with sim card as its not detecting the network. I dont get it what could be the problem. I cant even untick the automatic network search as i get error.
Will post you guys here some photos maybe you can help me out. I dont think is locked because i dont get any message when i insert sim to enter the unlock code. What could be the problem?
Please help. Thx

Is the Samsung running official FW?

Yes… original .

do you still have the imei number present in the settings and if you type *#06# ?

Might be sim locked by the carrier, you could theoretically still use the esim I believe if it isn't giving you an option to enter an unlock code.

Yes.. both imei show up.
How can i check for sure its sim locked?
Also, when i insert any sim, for one second the “no signal sign” near the battery goes away then comes back instant.. and it doesnt ask for any pin…
Thanks for your inputs

I have read about this issue before as well. Is this a "dual sim" model? Try the other slot if it is, and also try leaving the sim in and rebooting. You could also try "reset network settings" under settings. I'll have a look to see if I can find the thread where people said they had a fix.

is it yours from brand new? and have you checked to see if it black listed? also, there seems to be an issue with some Samsung where they are forced into airplane mode the only way you see this is the notification panel the airplane model toggle is half-lit blue I could be something to do with that. Failing that it could also be if you have dropped the device the ribbon may have come loose as this is a common issue with Samsung a range and that's all I'm seeming to fix lately

Hello. No, didnt buy new. I got it used.Yes its dual sim model. It doesnt appear as blacklisted.
Its not in airplane mode for sure. Also i did factory reset and also wrote all stock firmware ap cm bl csc from samfirmware..but its the same as before.
Also, esim doesnt show up under the sim card manager.

try *#2263#* to change bands, or *#0011#

Maybe also try to put the sim in the other slot, and see what happens. If all the same, try someone elses SIM card for a minute to see. Maybe your sim has become slightly damaged but your iphone still manages to read it, while for some reason the s21 is not managing.

Just tried the sim in my sisters s20 and works. Also tried her sim into this new phone and same . Even if i put in sim1 or sim2.

Found this online:
"In Settings go to network mode and set this to 3G only. Then restart your phone. This works in my case."

Thanks for your sugestion. But its the same…

I had the same issue on single sim korean unit...but factory reset resolved the issue. Actually i used to disable carrier apps which was causing this issue.

Question Mi 11 ultra isn't getting phone signal

Hey everyone. I bought a Mi 11 Ultra from china but I don't know why isn't getting signal at all. It detects the SIM but it doesn't let me make or receive calls neither messages, and obviously it doesn't connect to mobile networks. Can somebody help please?

Where are you, what network are you trying to use and have you got some screenshots of your network and SIM settings?

Hey, thanks for answering! Im in Mexico and about the network, any of them. I thought of changing the ROM from the CN to the global one to see if that help, but I need the mobile data to unlock the bootloader, and since the phone isn't getting signal, I cant do that.
P. S. Sorry, what do you mean by SIM settings?

Attached are screenshot of my SIM settings. Yours will be similar. Make sure your apn is set correctly. Make sure your SIM is recognised. Just basic setting checks. May be try other sim slot and of course, make sure it's right way up for either slot.
Without any screenshot I cannot see what may be wrong, so start again with SIM. Shiny side outwards and make sure it is recognised.

Hi again. Yeah, I have tried with both slots for the Sim, each one the correct way, but is the same result for both of them. Thanks for the example of the SIM settings, now I attach mine. As you may see, the SIM is getting recognized, just don't know why isn't getting signal. I've also tried with other company's SIMs, but I get no different result.

Looks good. I think you need to try with another SIM on different network and same. Try this SIM in different phone as it looks all good on screenshot but may be provider has not enabled it properly. If different network SIM known to be working doesn't work in your it must be hardware, hopefully not .

Also look at settings, all specs. Check SIM status and press 5 times on memory for deep phone info.

Hello and thank you again! Yeah... I've tried different SIM from different companys, all of them known to be working, but none of them has worked on this phone. I'm starting to lose hope... But here are the other settings, just to make sure isn't about software

The screenshot show that your radio is off. This is saying that your phone SIM is not turned on for some reason.
There is not much anyone remotely can do, if you are unable to get it turned on.
Maybe someone else has an idea? If not, and it cannot be resolved by resetting the mobile network ( in settings somewhere) or phone reset, then it may be back to seller as a hardware fault. Sorry I can't help. Let's hope someone else can?

Thanks a lot for your effort. Since you told me that the problem could be the hardware, I asked the seller about this issue and he told me that this problem is covered by the warranty, so I'll send the phone back to them. Again thanks a lot for answering!!

Just for info have you seen this thread about att? https://forum.xda-developers.com/t/not-a-recognized-device-by-att.4462649/#post-87088003

No, I hadn't heard about that, but still, I wouldn't hesitate on changing my provider if another one works, but since I tried changing to another provider SIM and nothing happened, I guess it was a hardware problem. Thanks a lot for the info!

Try doing manual search of network. If it shows nothing then try checking network frequencies of your network provider and comparing them with this phone supported frequencies. Sometimes its due to your network provider doesn't operate the frequency which this phone supports.

No mobile network connection, no IMEI

Hello,
my Xiaomi Mi 9T Pro running on stock MIUI Global 12.5.1.0 (RFKEUXM) can now suddenly not connect to my mobile carrier.
I hope somebody can help me out.
Some facts and stuff I have tried:
The connectivity icon on the top is just grayed out now and shows an X.
But that was not the case in the morning today.
At that time it showed full bars, but not the usual 4G text and the mobile internet did not work. After some attempts written below it is now just gray.
Mobile internet and cell service do not work.
I have rebooted multiple times.
The IMEI for both SIM slots is shown as 0.
No baseband version is shown.
(I am sure that this was also not the case early in the morning.)
I have never installed a custom ROM on this device, bootloader was never unlocked.
The SIM card is correctly inserted and the phone number is shown in the settings for SIM slot 1.
Trying SIM slot 2 (incl. reboot) did not fix the problem.
The SIM status shows that the service is not available, also on the top left when the phone is locked. ("Dienst nicht verfügbar" in German locale.)
Trying the SIM in another phone works, which I think makes it not a carrier problem.
Trying another SIM in my phone also does not work.
I unfortunately had dropped the phone days before, but no damage visible at all (phone case FTW).
Also it worked without problems, which makes me hope this is not hardware related.
WLAN works, so internet connectivity is possible.
Phone is out of warranty.
I did search for other threads with similar issues, but they all seem to be related to having flashed custom ROMs and then losing the IMEI.
Does somebody have any idea how I can fix this?
Thank you!
Edit: I just remembered/saw that I did do the "Xiaomi Service Framework" system app update to version 6.0.6-G yesterday night, maybe that caused the problem? Currently researching on how to roll that back. If somebody knows, please do tell.

Did you check Settings, SIM cards and Mobile networks, SIM 1 (if SIM is in Slot 1)
Do you have Turn on? If Turned Off, then do Turn On
If not, ie if it does not recognize the SIM card, then it looks like a hardware issue
Assuming, as you say, that SIM card is ok, correctly inserted, and that phone runs only the stock firmware - hence no root, no custom ROM, no custom Recovery (that user could possibly wipe partitions), etc
Maybe, some connection got loose and later disconnected completely

Thanks for you answer.
I am sure the SIM is inserted correctly and working. It's been in there probably for years now.
Don't know if you saw my update above about "Xiaomi Service Framework". Checking that right now. Maybe I should just do a factory reset.
What I have noticed now a couple of times is that the phone crashes and reboots, just now happened when I connect for USB debugging or before when trying to enter the SIM pin after a reboot, ...

Agreed, therefore I am sure the SIM is recognized. The phone even shows my number and the SIM has the carrier name.

If the carrier name is recognized, then IMEI cannot be NULL

Try to play with Preferred network type setting
Maybe something really got wrong with the updated Framework

AFAIK too - but without IMEI it could not attach to the network and therefore cannot show carrier name
Hence strange, and/or the contradictory descriptions/observations

Ohh, sry there is a misunderstanding.
The carrier name is only shown as the NAME of the SIM card (I guess it is stored on there or the phone has remembered it). But there is NO connection or carrier name shown in the top notification bar.

Yeah but you still have unknown IMEI - that's something that should have not happened
Anyway, go to Preferred Network Type and try with Prefer 4G, Prefer 3G or Prefer 2G - maybe, with the updated Framework, something went wrong with the bands support or so
If it wouldn't help, then I'm out of the ideas how to solve

So I did do a hard reset now, and it worked for a short time (IMEI is back), then it doesn't again, and ... just now again. It really is not stable.
Thx. I will post updates when I know more.

Unfortunately the phone keeps crashing and rebooting when using it. It just freezes and restarts, and sometimes it takes a long time to restart (seems like a crash loop).
Twice I also saw some graphic artifacts (bright magenta and green) on a small part of the screen.
I don't think this is just a mobile network connection problem anymore.
BTW: I have installed an older version of Xiaomi Service Framework (also the hard reset reverted it to a much older version), but that did not help.

Hey!!
I hope you doing great
Did you manage to solve the issue?

@Fawad Hussain
Unfortunately I could not solve it, so I am not able to use the device anymore.
Btw, as far as I can see there is no current smartphone without a notch/punch hole which is not gigantic (ASUS Rog Phone 6).

Same thing happened to me, I have managed to get it thanks to this guy in the video which I don't understand what he is saying but I just followed his steps, so if you are looking for a solution this video is.

But my device is not rooted and bootloader is locked, I tried ways but don't know how to root it or unlock bootloader properly
