Hello!
I have this s10e from Verizon and it is network unlock (I talked to Verizon to confirm this), well I bought it new and as soon as I turn it on, it started to upgrade to Android 11. All the update went without any issue, anyway when update was completed. I inserted my SIM card and I did not connect to the mobile network. I went to settings and open connections > Mobile networks change from Global to LTE/GSM/UMTS and manual to select the network. Network selected and I got the message "Can't register on the network" , I try again and it connects but after some minutes it lost the signal and got the message "Unable to connect, try later"
I have try several options, all with the same result, it connects for a while then it lost the connection and it won't reconnect until I try it manually...
These is what I have tried (not ordered in the way I tried them)
- Network Reset (including APN reset to default)
- Manually select the network (I go from Global to LTE/GSM/UMTS and backwards)
- Pull out the SIM, turn off the cell, insert SIM turn it on. When phone turns on sometimes it connects immediately to the mobile network but after it completes the initialization, the cell disconects.
- Erase the cache from the Phone app.
- Wipe cache
- Factory reset
I know it is not the phone because I have a Verizon SIM card and when I inserted it, the cell works flawless, actually since I'm out of USA, the cell connects to the same mobile network (on roaming) I'm trying to use with my SIM card. So I was thinking of downgrade to Android 11 but I found some threads where they reported the same issue (with Android 10) but no solution or they pointed to the workarounds I already tried so I don't think it is an Android 11 bug.
Does anyone knows something about this? any workaround?
Thank you!!

Just guessing as your have already tried many things.
Maybe you still have Verizon CSC installed what works fine with the Verizon SIM card, but leads to unstable mobile connection with another SIM card.
To check, download unbranded firmware for your region and flash it with Odin on PC via USB cable to your phone.
Use the CSC file ... Not the Home_CSC. This will wipe your data.
How this will help.

okay odd one, I was using the nav today, going to a restaraunt, and it stuck at the searching for GPS, mid directions
so I force pulled the battery after it froze, as I couldnt shut it down with app killer, or task manager
phone boots up, wifi works, but now it wont see my SIM CARD for some reason
I already factory reset through the menu section
I cant factory reset since I have CWM (using nvflash) installed and power, volume takes me to CWM for some reason
logcat included
and my cell standby has been at 71% all day
I'm having the same problem...
I turned my phone off this morning for a meeting, turned it back on and now the phone doesn't see the SIM. I flashed CWM 3.1.0.1 yesterday, could that be doing it? I'm not sure how it would be...
I noticed that happened to me a few times, I had to reboot the device on one occasion, and on the other I had to get a new sim card, as all my account data was wiped
I never figured out the issue, just go get a new sim card would be my advice
also watch what charger you use, as I tend to think my generic mini adapter may gave fried one or both of my sim cards
T-Mobile Nationwide Network Issues
I've had a similar problem. After calling T-Mobile I found out that they're having network issues and that manually selecting a Network Operator fixes the issues. I was told that if your phone leaves the network or if you disable your GSM/UMTS radio (airplan mode) devices are unable to automatically re-join t-mobile's network.
To join a network manually go to Settings > Wireless & Netowrks > Mobile Networks > Network Operators > Search Networks > Select any Tmobile Network
NOTE: T-Mobile networks will look grayed out but a long press should do it.
I have the D6633 and the phone works great except that it won't connect to the 4G/3G/2G/LTE network. I can make calls, send sms normally. It even recognizes both sim cards connected. But internet only over wi-fi.
I called my operator, they say the phone is configured correctly, I tried my brother's sim card from another operator and the same happens.
So, the phone is clearly unlocked, if not it wouldn't recognize the sim cards at all. But no connection to the internet...
Any suggestions? I already did four factory resets, I recovered the Rom using sony software... Starting to get anxious here

Despite what your operator says, check your phone is configured correctly. Check the APN - copy it from someone else with the same phone on the same network. Which one are you on? Go into the network options and select 4g, or 3g, etc, one at a time. Select the network to connect to manually; you might have a 2g, 3g and 4g connection to chose from; try all of them.
If that fails, especially with what you said about your brother's sim card, it does sound like it's faulty.

Download Internet and MMS. Under settings, More, Internet Settings.
Double check that you have a tick box in Mobile data traffic under settings, More, Mobile Networks
If that doesn't work, then select Mobile networks, Network Operators, note this is quite slow, but should show a list of carriers or bands. Select the one for your sim, which will re-establish with the carrier (and should download the APN's) Access Point Names. If not talk to your operator what these should be and add them if they don't exist (they normally will have info about them on their internet sites.

That worked. I could not configure APN manually, it would not save no matter how many times I configured it. SO I used an APN APP from plaster and it worked. Thank you for the enlightenment!
good to hear it worked out
Hello,
I have a Nexus 5 phone that came with Kitkat a few months back. The phone worked without issues until I decided to update to Lollipop 5.0 (OTA update) at the end of November. Initially the phone started to have troubles to detect the network at certain times - typically "playing" with the settings "Preferred network type" by changing from 4G to 2G, restarting, letting the phone detect the network on 2G mode and change back to 3G or 4G would fix the problem. The issue became more and more frequent until a point where i can not change the "Preferred network type" from 4G to any other type (as if it is "glued" on that setting). At this point my phone does not recognize at all the cellular network but It does seem to recognize the SIM card since i need to enter the 4 digit code to unlock SIM and it displays the network name, just no service.
I've researched the internet and I've tried several things but nothing seems to fix it such as restart mobile, change to airplane mode and back, take out and re-insert SIM card, request new SIM card from operator. The APN settings seem to be OK.
I've noticed that a new 5.1 version just came out and although I was not fully familiar with the process i decided to give it a try (after reading several instructions) and update manually (using factory images posted) and see if that would fix it. The phone is now with version 5.1 and still can't recognize the cellular network - no service. Everything else works fine, including Wi-Fi.
Has anyone experienced such issue after OTA update? The only odd thing I can think of is that I did the initial OTA update to 5.0 in US while i was on travel from Europe, but I can't say if this would in some way contribute to the issue. The mobile is D821 model.
Since I was stuck and mobile is within warranty period, I have sent it to service repair. I would be interested to know ideas of what could be the issue cause.
Sorry for long message, any help would be very much appreciated.

Hi, I'm on CM 12.1 and my OPO won't register on networks at boot (I'm on Virgin UK). I have to manually go to Mobile Networks > Network Operators and select EE (which is a network Virgin uses). After that everything works fine, I have network and data. But if I connect to WiFi, data will be lost when I disconnect and won't come back unless I manually register to the network again. Also, network will drop much more often since I only use EE and the phone won't automatically connect to other networks. If I go to Mobile Networks > Network Operators > Choose Automatically the phone disconnects from network and I get "Emergency Calls Only".
NOTE: The SIM works in another phone without problem. However, my other SIM works perfectly fine in my OPO.
CONCLUSION: My guess is that the settings for the Virgin SIM failed to download correctly. I had to manually add the Virgin APN to use data (which I usually don't have to).
QUESTIONS: Is there a way to reset the SIM settings stored on the phone without factory resetting? I might be wrong, any other ideas on how to solve my problem?
Thanks, Dan
I am currently in Italy using a Vodafone UK sim card, it's been working perfectly (apart from randomly dropping complete signal periodically) but now it's just completely died, as in it won't find a signal at all to connect to any network let alone data roaming. I have contacted Vodafone who said there's nothing wrong at their end and the worst thing is it was working perfectly till this evening. So now it sometimes says emergency calls only or just the ring with a line through it as it cannot find any signal at all. I have tried doing manual network operator selection and automatic but still nothing... Any ideas? It's a g9550 128/6gb
Update I now have 3g data but it says "no network connection" and I cannot send receive texts or phone calls, yet I have full data...

Consequences of buying a CN/HK variant....
They usually have network connectivity issues, not surprising. Try removing the SIM card, turning the phone off, wiping cache in recovery, insert the SIM card, and then reboot. Then manually go and search for a network in settings and force it to connect to Vodafone Italy, should work.
It's working now again, I didn't do anything lol it just started working on its own accord! I'm now in Switzerland and all is good. My life is empty without my phone
It always happens to me when abroad. I am on O2. I have to select network manually and pickup different to the one which auto connect shows emergency calls only. Looks like some cells allowing me to connect but won't pass through calls
Do you also have a usa/china variant?
No, o2 UK from Samsung
