voice calls do not work anymore

[PabloBa_2873203]

Hi,

I have a LG G7, I have changed my number to Smarty in October. It was working fine, I was making voice calls and receiving calls, but now calls do not work. I have done the network setting and APN as suggested here.

everything else works normally, SMS received, and all WIFI options works fine.

it just stop working making and receiving calls. Although I had made calls in the past.

Any suggestions in how to solve it?

My guess would be that your phone is not compatible with Smarty's VoLTE (4G calling), or VoLTE is not turned on in your settings. Previously your phone was most likely dropping down to 3G to make or receive calls, but 3G has now been switched off in most areas.

The G7 is not specifically on Smarty's list of incompatible devices, but the proof is in the pudding, so if VoLTE is switched on in your settings and calls are not working, I'd say the likelihood is it's not compatible with Smarty.

Hi @PabloBa_2873203 

As @SmartyTrousers has mentioned, you need to have VoLTE turned on so that your phone can connect to the 4G network. VoLTE is necessary to be able to connect to all networks.
For your device you can check using these steps....

Enable Voice over LTE (VoLTE) on LG G7 One

1. Tap the Settings app.
2. Tap Network & Internet.
3. Tap Mobile networks.
4. Tap Advanced.
5. Ensure Enhanced 4G LTE Mode is on (tap the switch next to it to enable)

Hope this helps x
