LG G2 Stuck on "No Service"

[YajuShinki]

My phone has been acting up these past few months in which it randomly loses cell signal and won't reconnect no matter where I am. I went into Settings>About Phone>Status , and I saw that the phone number and MIN were both "unknown", while everything else was normal. It's even weirder when I go to the Network menu, because this is what it reads:
Network: unknown
Signal strength:0 dBm 99 asu
Mobile network type: unknown
Service state: radio off
Roaming: not roaming
Mobile network state: disconnected

On the lock screen, instead of " Searching for service ", it just says " No service." Whenever I try to make a call or send a text, I get a dialogue saying to turn off airplane mode first, even though airplane mode is already off. I have already tried restarting my phone, updating PRL and profile, and resetting MIN/MEID through the ##-------# codes after talking to Sprint about it. Nothing seems to be working. Please help!

Have you tried entering Recovery Mode and performing a System Cache Partition wipe?

I think the problem with the G2 is that there is no way to access a recovery menu unless you're rooted and have installed a custom recovery.

Go to Settings>Wireless & Networks>More>Mobile Networks>Preferred Network Type, and make sure it's selected appropriately.

Have you asked Sprint for a replacement SIM card?

 

[YajuShinki]

I don't see any "Preferred network type" menu, but there is a Network mode menu. I have that set to "Global". Also, I haven't asked them for a replacement SIM card yet. Do you think that based on these symptoms, it could be that the phone isn't reading the SIM card correctly?

 

[B. Diddy]

Can't be sure about the SIM card, sorry. I'm naive about how Sprint works--I'm not sure if the SIM is necessary for voice, or only data (since they use CDMA for voice, which doesn't require a SIM). The SIM might just be for 4G LTE data.

Try changing the network mode to LTE/CDMA.

 

[YajuShinki]

Tried doing that, but every time I change it instantly switches back to Global.

 

[YajuShinki]

Also, I just noticed that the PRL version is also listed as unknown.

 

[B. Diddy]

You're in the US, right? I'm assuming this, since you're on Sprint.

 

[YajuShinki]

Yes, I'm in continental U.S.

 

[B. Diddy]

Bring it in to your local Sprint store and show them the problem.

I just did. They said it was a problem with the CDMA; apparently it's not connected anymore. In order to reconnect it, they would need to perform a hard reset. There's some data on my phone (app information and such) that can't be backed up but that I want to keep, so I really don't want to do a hard reset...

 

[B. Diddy]

You may be able to back up your data using Helium, which doesn't require root.

 

[YajuShinki]

I just did a factory reset. It worked fine until I restarted the phone. Now it's at no service again, but the network seems to be on LTE/CDMA this time. I am extremely frustrated right now.

Sorry for my bad english. I just had this problem , when I opened the phone it said .com.shid.af somthing like that stopped and then my mobile network was gone. I mean ı did tried the open it but it didn't whatever ı do. Then I looked the internet and ı just returned the factory settings. Now its fine.

When the service is disabled in LG G3 mobile :
This might be mostly because network mode might have been changed in your mobile.

Observations :
1. Service disabled in home screen and no network.
2. Mobile network option in tethering &network -> mobile network is disabled.
3. Doesn't change even if you use different SIMs

Steps to resolve :
1.browse for 2G-3G ON OFF in Playstore.
2.download the app by curvefish
3.install the app
4. Now long press on your home screen and select 2G-3G ONOFF widget
5.In the network mode select "Global" or CDMA for 3G.
6. That's it !
just check your network connection. Switch off and on the mobile and check again!
