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

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 managed to install CM10 on my tipo but now I have no network to make or receive calls or texts and i can't seem to find out where i can choose my network.
When I go to settings>wireless and networks>more> it gives me the options of Airplane mode, VPN, Tethering & portable hotspot, and mobile networks. Clicking on mobile networks gives me data enabled (on or off), data roaming (on or off), national data roaming (on or off), and system select (home only and automatic)
Can anyone help please?
Thank you

I ticked on airplane mode, then ticked it off again and the type PIN code for the SIM appeared so I entered my PIN and in the wireless and network settings area, the airplane mode has disappeared, but added to the list is Access Point Names, Use only 2G networks (on or off), and Network Operators. When I select Network Operators, the phone searched for networks and returns with four Unknown networks and choose automatically which I did. I seem to have a signal now but I don't know if its on my network or how it is working (I'm on Three) as there is no indication as to what network I am on. I've rebooted and tried again but its still the same

Delzep - are you using tipo single or dual sim?
JL93 were you on stock jb before flashing cm10 Rom? You must be on ics, then flash cm10 Rom. Try flashing ics ftf now.

I borrowed the SIM card out of my AT&T 4G/LTE hotspot to see if I could turn my old phone into a hotspot. However, while it does connect to the network, it will only run in HSPA mode. I briefly got it to use LTE for about an hour, but the ROM was still randomly rebooting then, and I lost it on reboot. I did put the SIM back in the hotspot, and it does get 4g/LTE on that device, so it's not the SIM card or the service as near as I can tell.
I did try to use the *#*#4636#*#* menu, but it instantly reverts back to WCDMA preferred if I select anything other than unknown. The same happens if I attempt to switch to LTE in the mobile networks menu. I also tried setting the APN to AT&T Broadband (the APN used by the hotspot) as well as AT&T LTE. I found an older thread related to this, but there didn't seem to be a conclusion.
The only caveat here is that the SIM is only authorized for data, not voice or SMS.
Any ideas?
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 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.
