Help me resetting SIM/Network settings - Android Q&A, Help & Troubleshooting

(X/Post From Oneplus 6 Forum)
Hello,
Yesterday I called my network operator since I was the only one in the office (compared to others with the same network operator) unable to receive calls.
The support made me receive a Network Configuration SMS, I applied it and immediatly the SIM started to turn on and off (see link):

As of now, my SIM works on other phones, other SIM (from same and different network operator) works on my phone. Looks like a configuration issue directly connected to my SIM/IMEI.
Tried to reset what I've been able to reset, and to reflash ROM. The only option left is to factory reset, but I'd not like to.
Is there a way to reset the SIM configuration? I am rooted if needed.
Thank you!

[Q] "Unable to connect. Try later"

Hi there!
I've found several threads with this issue, but still not that serious like mine.
I've been using my GS II for 3 month without any problem, untill yesterday. During surfing on the net the network suddenly gone away and since I don't have mobile network connection. I've got IMEI, CSC, signal from provider (unlocked phone), my SIM card works in other devices, I also updated the firmware, I made several hard resets, checked other SIM cards, checked the problem with flight mode, but I haven't found any solutions. The signal sign is there in the upper corner, but I'm not able to connect to any providers for 48 hours.
Please help me. I don't know what to do
Maybe a country specific CSC change? I don't know how to do that. I have one .tar file for that but Odin can't install it. I'm a beginner here...
Thanks in advance...
Have you tried checking the access point settings?
Sent from my GT-I9100
Yes. They are fine. I've just changed them and put them to default again because there was no change.
When the phone went offline I was just surfing on the net so I did not change any options.
Any other ideas maybe?
Thanks...
try talking to your provider. Your account may have a problem which could be fixed by a simple reset on their end.
Thanks for the comment. Well, I've tried to use other sims for the same and also from other providers, even a sim from another country, and none of them worked. I also tried to put my sim into another phone and the sim works fine there. The only logical solution is that the problem is with the phone.
I guess it's worth a try, maybe they blocked the IMEI of the phone because of something? It's not a stolen mobile though.
Now I've got a flashed brand new mp4 player from samsung. Nice, it drives me crayz...
Another idea. While I was surfing on the net I installed "advanced task killer" (before the "crash" happened) and I killed some ordinary apps (not sure about this) then I just deleted the program. This connection rejecting thing happened after this. That's why I thought I should make a firmware update, maybe the problem was caused by this task killer. Well, don't know if the is a connection or not...
I have exactly the same proble with my Galaxy SII - I went on a long trip - when I got back it stopped working. Has anyone found a solution to this?
To reiterate - the phone sees all the networks, but when I select Vodafone UK I get the message "unable to select vodafone UK automatically". The sim card works fine in other phones - there is clearly an issue with the phone. The only thing that has changed is I have updated some of my apps on returning home.
Any ideas?

My CSC is XEU (correct for UK as far as I can see - and has worked for the past 3 months)
Sim card works fine in another phone
Network is fine (my wife is also on Vodafone and has no issues - my sim works on the network on her phone)
My Imei is correct
-Everyone else who has had this problem had no joy with a factory reset so I'm loathe to try it until I''ve tried everything else.
Any other ideas?
Just to recap:
The phone is stuck in emergency calls only mode
I can see all my local networks (Vodaphone, Orange etc...)
When I try to connect (in any of the modes 2g/3g) I get the error message
The sim card works fine in other phones
Other people's sim cards have the same issue in my phone
There are plenty of 'Emergency calls only' threads around, but the ones that have my exact symptoms never seem to get solved. Does anyone have any other ideas, or better, has anyone come across a thread where the issue was resolved? Getting pretty desperate.
tried rooting and flashing different modems maybe its a hardware problem with the modem.

i have the same problem in greece galaxy s2 i9100....in ics i havent network in 2.3.5 i have...i dont know why...in cm9 ics i have network...
Last update - I have flashed the phone to Ice Cream Sandwich, (LPQ version), which means I have:
Carried out a factory reset
Flashed a new ROM and Modem
When I rebooted it asked me for my carrier (Vodafone UK) and filled in the APN settings itself. I still have the same issue. I can't work out what is left that I haven't reset/reloaded that could still be causing issue. There can't be many settings left that aren't new?

i try to put manual apns but i cant save this in phone...in network search found my carrier but not conected...only with cm9 ics found network...pff...
Success?!?! It looks like we have tracked down the problem (extremely helpful input from another forum). Quick call to Vodafone and it turns out that my IMEI has been blacklisted (stolen!) Imagine my surprise - currently having a very interesting with Carphonewarehouse as to how hey managed to give me a stolen phone - should hopefully have everything resolved shortly

Very odd - when you first boot after a flash does it not ask you to select your contract type (that is the bit that automatically fills in the APN for me?)

this helped to me
Had the EXACT same issue on my Galaxy Note II for two days. My last hope was trying to restore my EFS with the EFS pro app.
Now when enabled my wifi at home and connected to my home network my sim prompted for the pin code.
Strange but I guess it was waiting for a connection (from my home wifi (not any other wifi) from a "half downloaded" app from the play store.
Anyways I'm happy this issue is resolved.
Does your phone prompt for a pincode when you start it? (mine said unable to complete download everytime it booted)
Hope this will help you guys...
Samsung Galaxy "Unable to connect. Try later" issue still remain
Hi guys,
I have the same issue with the following device:
Samsung Galaxy S3
I live in continental western Europe. Operators tried: BASE, MOBISTAR, PROXIMUS, POST.
The IMEI is correct, does not start with 00. The phone was bought from a shop, new, I have the invoice, so is legal, not stolen.
For some unknown reason, suddenly it does not want to connect to the mobile operators, any of them. I see "Emergency calls only". When I try to connect any one automatically or manually, I always get the message "Unable to connect. Try later".
The SIM card work well in another device, a Nokia C3-00. Another SIM does not work in my defective Samung S3. I sent back the device to the shop to be repaired and they gave it back to me saying it work very well, they just upgraded to the latest firmware, etc.
I am very annoyed because the device is unreliable. I have it in my pocket and do not realize it is not connected to the mobile network, I cannot be called or receive messages. Also I am unable to call.
The WIFI work well.
I tried everything, removing the SIM, inserting another, shutting down, enabling and disabling flight mode, nothing works.
But the later for some unkown reason and logic, it just work again for some time.
You guys wrote about some solution by looking in a folder, but I don't see that folder. Also you mention rooting. Does this mean cracking the phone? I do not wish to meddle with this, because I could destroy my device and I paid a lot for it. It will remove the warranty. So if you have a solution, please give a legal one.
Anyone have a hint or explanation for this strange behaviour?
Thanks a lot.
had a similar problem with galaxy core prime.
bought without a sim card and no knowledge of what network it was on.
every sim i tried was getting unable to connect error as i was trying to register on network
dont know if this will work for everyone as mine is a dual sim phone but here goes.
inserted two different sims from different providers, ee and vodafone.
reset phone to factory settings and when it booted back up, it recognised the ee sim card, went to mobile networks and network operators in settings and selected the ee network and presto, it registered ! used sim manager to select voda card and repeated selecting vodafone as carrier and it also registered straightaway
as i said none of the cards would register before on their own, but somehow this method worked for me.
hope this helps
had to set one sim to gsm only and other to autoconnect

[Q] Unlocked Galaxy S2 No Data

Hi guys,
I am on the Fido network.
I purchased the Galaxy S2 I9100 from Bell Mobility.
I unlocked the phone using cellunlocker.net.
Everything worked great once the phone was unlocked (data, voice, text, mms, etc).
Once I updated the APN and selected my network operator I noticed my date stamp on incoming texts was off by a few hours. I corrected this by calling my service provider who reset my SIM.
This is where the more serious problem started, the date stamp on the texts was corrected although I lost my data connection.
Another thing I wanted to mention was when restarting the S2, the data network mode (when holding the power button) automatically goes into "deactivated". I activate it right away although this still has no effect.
Can anyone help? The phone worked for just under 2 weeks with data, voice, etc. Now nothing........
=(

Go to mobile network settings - access point name. I'm guessing that there is no APN settings there. Google APN settings for your service provider or ring them and ask them. This should sort out your data connection
Hi,
All APN settings are correct, they were working prior to calling the service provider for a SIM reset. I rechecked them 10 million times to ensure all is well.
Using my wireless for now and even factory reset my phone but nothing.
Try deleting your apns and reconfigure them!

Just finished, I deleted my APN and created a new one. Still nothing, even when I reset to default. Also registered it on my network operator. This is very puzzling for me... I appreciate your response as I thought it was a great idea and was sure it would have worked! =(
Maybe try a buddies Fido sim to see if it helps.

Tell me what network your on and tell me what modem you are runinng? Take a screen shot of your APN settings. It will take 2 screen shots for the APN settings
I apologize for the delay as I was away for work until today...
The data works now.
I called into my service provider who at first stated they could not help me as my phone was unlocked. This was overcome as I still had the my Nexus S which I bought from my service provider which also had no data. After trouble shooting for 30 min on both phones (resetting, factory wiping, creating new APN's, etc) we were unable to get the data to work.
The tech rep then asked me to attend a Fido store (my provider), which I agreed to (rep asked me to insert my SIM into another Fido phone and try the data connection that way).
Within 10 min of the phone call my data connected just like that. Funny part is I didn't do anything to the S2.
I believe my provider switched off the data when I called in originally regarding my date stamp. Then when I called back they switched it back on knowing it wasn't any of my settings or the phone. This is just my theory.
My advice is never let your provider know you have an unlocked phone, especially Fido.
I appreciate your help and hope this helps anyone going forward.

Out of service area....

I can't make any calls / send any sms with my Xperia S, after I have been to a long trip to europe (I am back in UK now).
I tried the sim in another phone and it works!
I tried factory reset, flashed the firmware again, tried update service but no hope.
However the data has always been working (I can use internet)... just can't make calls ("network problem") .....
Every time I insert the sim into XS and boot it up, the network operator name appears for one second and becomes "no service" again.
What can I do? :S
push
have you contacted your netowrk service provider? maybe they can help with connection issues?
Maybe faulty cellular part in phone, or bad baseband on phone.

HI,
How about manually searching for the network provider ??
Setting --> Wireless and networks --> Mobile Netwrks --> Service providers

No service in Europe with Japanese SO-03F

Hi guys,
I own a Japanese Z2, originally by docomo (SO-03F) and flashed the English firmware I found in this forum (not sure for which area tho), except obviously the modem which I needed to use the docomo SIM.
I came back to Europe, unlocked the phone through an online service which worked fine but none of my SIMs can get a signal or behaves very weirdly.
I tried flashing the modem from the ROM I used before but then I couldn't get any reception and looking for networks through settings didn't show anything. With the Japanese ROM modem, I can find networks if I look manually but I can't connect to them. It shows "Selected network unavailable" and or "Can't connect to network at this time." after selecting the correct one.
I tried fiddling with the settings, different network types etc in the normal menu and in the one accessible through entering *#*#INFO#*#* but nothing helped. The phone number in the menu is shown correctly. As preferred network type, LTE/GSM/CDMA auto (PRL) is selected.
I have an older sim card in the right format which can't connect (works fine in other phones) but SOMETIMES I get like 2 bars for a few minutes. It's for phonecalls and SMS only. The internet only card I have is smaller so I need an adapter and won't connect at all. Is there something I can do about this?
Thanks a lot!

Data is not working for unlocked MetroPCS LG Stylo 4 (LMQ710MS)

Got a MetroPCS LG Stylo 4. It was unlocked after 6 months of service. Tested on different network and it was working fine.
Recently it was sent to india as a gift. After inserting new sim, voice call is working fine. However data is not working not even 3g/2g. Tried different network. Same issue. Tried to network reset and even factory reset. Same issue.
Is it missing band problem? Or data is locked ? As long I know, phone can be network locked. But never seen data locked.
Any suggestion?
Phone's Android version is 8.1.0

Try this...
Also ran across this phone dialer code that opens the Stylo 4s hidden menu...
277634#*#
With it you can Grant permissions to edit APN settings, edit the ant settings, enter into engineering mode, etc..
Also edit band settings..
I know I edited my APN settings removed xcap Added fota,Hipri
And so far seems as if my mobile data is running more smoothly and a little faster. I'm not sure if it's true about removing xcap removes the ability to tunnel your data to keep up with usage, I do know changing these three things has helped my data tremendously.
