Hi!
After weeks of flawless function my Xperia can not find my carriers phone network.
I have updated the phone to the new ROM but that does not help.
The phone finds the SIM card and asks for the code.
Strangly it can connect to internet through my carrier (Tele2).
But I can not get a connection to the phone network and make a normal phone call.
Is something wrong with the phone?
NO, cause with another carrier (Telenor) everything works pefect.
Then obviously something is wrong with my carrier (Tele2) or the SIM-card.
NO, cause when I put my Tele2 SIM-card in another device (Ipaq 6515) it works perfect.
The Ipaq is not a 3G-phone. Can that have anything to do with it?
I'm getting lost here, all help is appreciated.
(ORIGINAL MESSAGE
Hi!
After weeks of flawless function my Xperia has started to lose it's phone network.
I notice it after I wake my phone up from stand by mode.
It doesn't help to turn the phone option off and on in Comm manager, but it has sometimes helped turning flight mode on and off.
Other times I had to restart the phone.
This happens a couple of times every day, after long times of not using the phone. I have not been able to trigger this problem, so I don't know what causes it or exactly when it happens.
Strangly it can connect to HDSPA while it has lost the phone network.
I have also experienced som freezes when I'm flipping between the panels to much.
All help is appreciated, thanks.
It would be helpful if you could give us more information.
What ROM are you using
Which carrier you have
etc.

I'm using:
ROM 1.02.936.3
Radioversion 1.06.25.29
The carrier is Swedish Tele2.
In Sweden we have GSM-900 and GSM-1800.
Tele2 also provide me with UMTS and HSDPA.
Today the problem became worse.
Even after repeated soft restarts it refused to find the phone network.
Then I change SIM-card to another carrier and it found the network.
I also tried the SIM-card that's giving me problems in another device. Works fine.
So both SIM-cards works. I'm now gonna go with the new carrier during the day to see if the problem come back.
If anyone have any ideas, please help.

All I can say that Xperia sometimes looks for the signal a bit longer it should IMO,
but I also know that carriers have many many problems usually and they're also often responsible for signal drops in some places too.
I know that 'cos I was talking to my carrier many times about it and learned something about it...
have u tried hard resetting the phone or re-installing the software? ..
if u run the sony update software it will give u the option to re-install your phones software - not sure if that has the same effect as a hard reset ..
probably worth trying

Thanks for answering, I have now done a total reinstall and updated the phone to the newest R2... ROM.
The problem remains.
The phone finds the SIM card and asks for the code.
It can connect to internet through my carrier (Tele2).
But I can not get a connection to the phone network and make a normal phone call.

NO, cause when I put my Tele2 SIM-card in another device (Ipaq 6515) it works perfect.
I'm getting lost here, more ideas is appreciated. Tomorrow I will call Tele2 support.
Have you tried disabling 3G/HSDPA?
Chance that you have very poor 3G on your phone, whilst the IPAC is picking up ok 2G.

Thanks for replying.
I disabled HSDPA/HSUPA in the advanced network menu. But it didn't help.
I also tried to choose GSM only in the phone seetings menue. But I could not even change the setting. Just got an error message about not being able to change the network (or something similar).
Is there any other setting that might be worth trying?

Having worked for several phone companies a few years at customer service I know what the procedure is.
-First thing they do is ask you to do a "crosstest", try your SIM in another phone and see if that works.
-You'll tell them that you did that and everything works fine when you use another phone.
-They'll automatically conclude that there's something wrong with your phone (correctly)
-They'll ask you if you could do a hard reset ( You did that too)
-Then maybe they'll try and reset the network (which almost never works)
Basically they'll have no other choice then for you to return it and have them look at the problem / replace your phone.
I don't think we here can help you with your problem
Good luck and keep us posted
Get a new SIM card. I've seen problems like this before, and an updated SIM card solved it.
The best way would be to test your SIM card in a similar phone, the ipaq not being close because it's not even 3G.

I'm so confused right now.
Got my new sim card today, problem remains.
I call the carrier support and after they've looked the IMEI-number up they say that the phone is barred by an external operator. They won't tell me the reason and by what operator.
So I call the other carriers support and after they've done a IMEI-search they say that the phone is not locked in any way, by them or any other operator. After have been talking to Xperia support they come to the same conclusion. The phone is not locked but agree to that something is wrong, with phone or carriers, and they want me to try with a third carrier.
Final
I've handed in my phone to the seller and got another one back instead.
The end
Exact same problem
Howdy folks,
I have the exact same problem: My Xperia has worked fine for a month. Suddenly I can't register with Tele2 network (tried another Tele2 card as well that didn't work) for calling but have access to data channel so I can surf. Got told by the Tele2 support that my phone was fu**ed up. Got pissed off. Tried a sim for another provider (Telenor) that worked. Called the Tele2 support again. They noticed that I have an old (2g) sim, so they will send a new (3g) card to test if that fixes this mess. It should arrive late this week or early the next. Can't wait...
I'll keep you posted in this thread (or, if I should instead have made a new thread, a moderator may spank me and I will do better).

Nope, new sim-card didn't fix it. But I have found at least one other xperia-user with this problem...
bad GSM signal
I have a X1
rom 1.03.931.10
radio 1.10.25.18
protocol version 52.56.25.29W
and since from the start I have bad GSM signal I have like 1-2 lines onli and it go up to 5line but onli from time to time (and then it drops again to 1-2line or none but If Itray to call is working or I get called but I can berly hear them bicose of the bad signal) on O2 network and in T-mobile is the same no mather wher I'm in town or outside of town; I'm in UK
is the phone damaged?? or...
sry for my bad english
My phone does the same thing
My x1 has had no problem with phone function or network. However, from the last week, the signal began to be lost sometimes, and the machine turned off automatically. and finally today, there is no signal at all.
MY SIM card works with other phones, so, I thought it might be software problem, and hard reseted with new rom. However, still no signal. It keeps looking. Does anyone have the same problem, and hopefully, solution?
I´m using my X1i with Tele2 as my service provider,but i don´t have any problems with signalstrength.. Works just fine..

I know I should've introdouced myself first, and that this is a strange first post, but:
HOLY SMOKES!!!
Xperia has FIVE reception bars????!!!!!
I always thought that 3 is the max value, since it only happened once that it went up to three bars, rest of the time it's maximum 2, usually 1.
I am also on Tele2 carrier, in Sweden that is, and since yesterday, I have no reception AT ALL.
Nothing.
Tried turning off 3G(or whatever it's called), nothing happens.
Tested with 3 other cards (one Tele2, one Telenor, one Telia) - all seem to be working okay. Except that the Tele2 one has slightly lower reception than the others.
Tested with 3 other phones as well - iPhone 3GS, Nokia 5800 Xpress Music, HTC Desire. All of them worked perfectly. Full coverage on that super-fast network thingy(the 3G symbol on iPhone).
Internet is just flowing on other phones - but Xperia is just falling behind in the most important section - reception.
Calls get dropped (2/3 of the calls), I must send same message at least 3 times in order to get it sent, Internet is crappy - if there's any at all.
Any kind of guidance is mostly appreciated.
P.S. A bit of those numbers which seem to be important:
Microsoft Windows MobileR 6.1 Professional
CE-OS 5.2.19608 (Build 19608.1.2.60)
ROM-version: 1.05.936.9
ROM-date: 04/19/09
Radioversion: 1.14.25.55
Protocol version: 1.0.11842.32680
Since all of you seem to have problems with one and the same carrier (Tele2) why don't you simply switch to another one? I once had a problem that was very alike the one described here and after several unsuccessful attempts of the carrier to fix it I simply switched to another one and all my problems were gone.
My phone was stolen and person was stupid enough to call back to my wife and we got his number an he was forced to give it back. I called my network and they barred a phone. Now when I got it back I called my network and they ordered "unbarring". They said it can take up to 2 days.
I still waiting (24h)and when I start my phone now it says "SIM card changed" and I have phone pad and "Emergency phone calls be made" and thats it. It never comes to Touch Flo an I can't navigate to something other.
My question is it right or something is done to my phone while it was gone. I couldn't reflash it because it doesn't have access to internal storage. It says G but no networks bars...
Is it supposed to look like this when phone is barred?
I thought that when phone is barred via IMEI nr that you can't use phone for calls and sms (because it's baned on any network) but still TouchFlo should be accessible. I didn't realize that phone itself can be locked...

i was answering that part of your question lol yes thats how it should look when your imei is barred, if you look in the development and hacking section there is software there to change ur imei number wich will unbar it, you will almost certainly be braking the law doing it tho so i suggest you try other methods first,

Tnx for your answer. No, I don't want to change IMEI nr. Why should I do that now when I know that is "only" barred? That is my phone and I will wait for network to fix this.

I think a 3rd party software had been installed in your phone. To give you an idea, I'm using this great FREE software so I can control my phone just in case if it's stolen:

HELP!!!
This morning (after 3 days) my phone has been "unbarred", yeaaaa!
But...
I had my SIM card X (may old private number) in phone when it's start working and I replaced with SIM card Y (my job number) which I was using with my phone over a year before it was stolen/barred. And guess what? Now when I put in SIM card Y (job) it doesn't work!!! Of course I tried card Y in another telephone and it is working!
My Y (job)network says that the still can see that my phone is barred and they hope that it will be unbarred for their network with delay because it was not "home network" for telephone . Phone was not locked to none of networks.
Any clue on this?
This one is pretty *beep* up! The phone was working pretty fine last time I looked at it (30 minutes ago), I put it in my pocket and had dinner (as always), then I took it out to make a phone call and it says just "Emergency call only" instead of showing my phone operator (3 ITA). I tried rebooting, no luck! Still the same.
Strange thing is that it has signal (full) but I can't make/receive calls or use data network. If I go under Settings -> Wifi -> Mobile networks settings and I look for operators it searches and I can see all of them (mine included) but I cannot select it!! Neither mine nor another one (TIM, which is the roaming default one for my operator when there's no signal)...it just says "Unable to connect. Try later".
Weirdest thing of all is that I AM RECEIVING PUSH EMAILS from gmail!!!
Anyone has a clue about this??? Has it ever happened to anyone?
Btw, I'm using zeroblaster rom, which is based on official italian froyo firmware...everything was working so good until ten minutes ago!
Hope I don't have to reflash...
Just got weirder: put my sim on another phone...it registers without problems on the network.
Then put the other's phone's sim on my sgs...it registers without problems.
Then switched again: Emergency calls only
WHAT THE ****??!? (what are we? children? sorry mod...lol)

It is WAY weird imho! The weirdest thing being that I'm still receiving gmail's pushes after 5-6 reboots while it keeps saying "emergency calls only".
Also I saw that when the phone boots, while it's loading the launcher, widgets, etc. it gets the connection for like 2-3 seconds it shows my operator (in the lockscreen), then it switches to "emergency calls only"...
I'll wait another hour (maybe as the issue came out of nowhere it'll go away? ) then I'll try reflashing...since I had to change to k9 anyway to fix the /system corruption etc. -.- I'm already backing-up...
Hope the flash will fix this though...it's really a pain in the ***

No that's not it, because putting H3G sim on another phone WORKS!!
And anyway, when H3G's down it uses TIM as roaming...this time I cannot even select TIM as operator, it refuses! And normally you can always use tim in roaming if you want (even when H3G has signal...)!

Hmmmm... That is weird alright.
If you purchased your SGS through your carrier H3G I would still call them to report it as there are now 2 of you experiencing the same issue so it cant just be phone related and if it is then they will have to honor your warranty to replace or fix it (both of you)...
It's happening to me too.. i also use H3G Italy on my Galaxy S and i have this issue since around 19:00 this evening with my work SIM card
I have a Tayutama 1.0.0 ROM based on the JPM Froyo ROM.. it's the first time this is happening to me..

Well... That is 3 of you so it must be carrier related in some way. Again... Call your carrier and explain what is happening. Explain that when you put the sim into a different device it works ok but in the SGS all you can do is make emergency calls and they should be able to tell you what is going on.
Make sure to post back as I am now interested in seeing what your issue is / was...

You just answered your own question I think. "service state: out of service" says it all I believe even if the sim cards DO rgister on another phone for whatever reason.
The fact is the they dont register on your Galaxy S so call them and report the issue and they should be able to help you...
Yeah well, you see, that could be a problem because...H3G has a TERRIBLE customer care, lol! Basically the thing is you can't call them...you need to send an email, and an answer will arrive 2-3 days later. That's not good enough for me! If it doesn't get fixed tomorrow I'll go directly to a 3shop and they'll call someone higher to understand this. Hope they fix it soon though!
Anyway...now I have a strong curiosity: could it be JUST the SGS? If so...WHY???? I tried putting the simcard on a Nokia E71 and it works...does anyone have another android phone with H3G? Could it be somehow "system"-related? Because I can't figure out why a specific phone device shouldn't work point-blank with my operator! And that's even a phone they sell themselves!!
Rebooted and now it WORKS! THANK GOD (even if I'm atheist....)
Still would like to know why it did this!
I had a similar problem where if I was in an area with bad reception it would default to emergency calls only. But the funny thing is when I go into the menu settings I can see my carrier and when I try to select it, it says network unreachable. Eventually I would get signal but the tab still says emergency calls only. Tried making calls but it wouldn't allow.
Initially to rectify the problem I rebooted the phone and that worked but got annoying. So I realised that if I left it for a couple of mins whenn it had reception it would fix itself. As of recently (last 2 months) I haven't any problems.
Btw i'm on jpm and my carrier is 3 australia. It's rubbish service

Hello,
Same thing happening to me... It must have something related to signal strength, i went downtown and phone was perfectly fine.
But at home it keeps loosing signal, i dialed *#*#0011#*#* and it shows changing BAND... as if it was searching for service on different bands...
But the thing is, i tried inserting the SIM on other 2 phones and i get a FULL signal, so i guess signal is coming pretty intense here... why is the SGS loosing it? i have no idea...
By the way, i am from Brazil, and that started happening after i flashed my rom to FROYO VJJPA..
me too, has no signal at home but works for another phone.

Same is happening to me. Serive state says out of service so could registering the sim card to phone be the actual isuue?
I had this happen in 3 different instances:
1) Come back to the phone, which was lying on the table, to find that it was restarted. Happened 3 times in 5 minutes.
2) Another time, the phone restarted for no reason - I came back and it was asking for pattern instead of fingerprint because it restarted.
3) In a 20 minute drive, the phone restarted twice, which was announced by the Bluetooth car unit. I stopped each time and verified that the phone actually restarted.
At first, I thought it was me holding the power button wrong and it getting stuck.
But I have tried my best to not push the power button in any weird way, and then it still happened.
Moreover, here's an interesting exchange between, apparently, ZTE and users. Credit to oberio28:
5, sometimes the phone will automatically restart, how is this going?
A: We have located the reason and will resolve this issue in the next release, please update to the latest version to experience.

It doesn't happen for me, Global EU 2.09
Just updated from 1.11 to 1.15 NA. Going to see if that fixes reboots.
Also, why the hell doesn't the phone remember the Bluetooth volume level? Is that a Pie thing?

Thanks for the info.
Do you know anything about this problem?
"I use ATT as as carrier, and I tried several of their sim cards. As soon as I install the card, that Sim slot (1 or 2) truncates its IMEI from 15 to 14 digits, so it thinks that's it's a CDMA sim card. I think this is the reason why I cannot access GSM calling settings such as Call Forwarding. It says "Network or Sim card error."

I use ATT prepaid mine does the same but the last digit is a check, meaning once sim is activated it helps hide your full IMEI. I get 4g LTE and no Voice HD calling, hence it always reverts to 4g/3g in calls. Got to love US carriers.

Thanks. It was explained to me at an ATT store that Voice over LTE was not available for a prepaid plan.
However, can you change Call Forwarding settings (I cannot, and I am not sure what the problem is):

Thanks. It was explained to me at an ATT store that Voice over LTE was not available for a prepaid plan.
However, can you change Call Forwarding settings (I cannot, and I am not sure what the problem is):

Yeah I get the same error, I don't think it's phone though. My other phone is Poco F1 and its all custom ROM with no LTE bands and it does the same. But both can transmit/receive calls with same sim though...I think its more the network and not being AT&T branded phone.

Thanks for the info.
Do you know anything about this problem?
"I use ATT as as carrier, and I tried several of their sim cards. As soon as I install the card, that Sim slot (1 or 2) truncates its IMEI from 15 to 14 digits, so it thinks that's it's a CDMA sim card. I think this is the reason why I cannot access GSM calling settings such as Call Forwarding. It says "Network or Sim card error."

Thanks. Here's more info that may be relevant.
1) Oneplus 6, global version, doesn't have this problem, that is not being able to set up call forwarding from the phone.
2) Whenever AT&T sim card is inserted into a slot (1 or 2), that slot truncates its IMEI from 15 to 14 digits by removing the last digit.
So, if without the sim card IMEI 1 is XXX...XXX5, it becomes XXX...XXX when the sim card is inserted into slot 1. Same happens to IMEI 2 if the card is inserted into slot 2.

Thanks for trying to help fellow Nubians BTW, the XDA review of RM3 was disastrous, IMO. So unfair. Whoever did that review needs to go back to basic training.

Done.
Hi,
I just bought a Mi 9 for my gf as Birthday gift and have a big problem with it.
We use her Simcard from her further phone, which works there without issues, but the Mi 9 just let her use Data on the simcard (internet). No calls or texts in-/ outbound are possible. It always shows that no mobile network is available.
I already readded all APNs (Internet, LTE, GPRS) and tried a couple different network settings (*#*#4636#*#*). I'm not sure why this issue appears and searched allover the internet. Seems like noone else have this problem.
Version is 11.0.2.0(QFAMIXM) with locked bootloader. Could it be that seller flashed something wrong, modem type or whatever? Carrier lock wouldn't let us use the actual sim right? My own sim as well just work with data so it need to be an issue with the phone.
Thanks in advance
Chris
Noone have any idea what the issue could be?
This seems like an operator related issue and probably has nothing to do with the Mi9. Try operator related forums for more help. The only thing that comes to mind is to get a new sim from the operator.

Question:
Does mi9 recognize the SIM Card? Does mi9 ASK for your SIM Card PIN? Or does mi9 say 'no SIM Card installed'?
Hi,
Sim is recognized and contacts shown. Sim pin is deactivated so the Phone don't ask.
Mobile Network is shown and active and data/ internet works. Its just the GPRS funtions (Text, Calls) which don't work. When I try to call I get the "Mobile Network isn't available" message and texts don't sent.
Thanks

The Sim works fine in another phone and my sim which works as well, shows the same errors in the Mi 9. So it must be an phone issue.

What operator do you use? What operators are the respective cards you have tried in the Mi9? Did you buy the phone from a private person and not new in a sealed package? In this case contact the seller.

Do you have 2 simcards installed?
You also might try to reset the modems, howto you can find when searching the forum
Just 1 sim installed. 2nd slot shows the same issues. Will check the forum for modem reset thanks.
Hi,
Weirdly the phone seem to have a Carrier Lock. My gf uses SMART Prepaid here on the Philippines and as said just mobile data was working. Yesterday she switched the SIM for testing to Globe and with this SIM everything works. 4G is available and calls/ texts work as they should.
I'm still confused about this. If the Phone would be carrier locked, should another Carrier SIM not be functional at all? I don't get why Data connections are working then.
For now the solution is to get another SIM. Probably let it unlock in a store.
Regards
Chris
