LG V20 F800L Korean Variant LTE Network connectivity Issue

[Android Central Question]

Hi, I am not sure if this question is valid or not but i have bough a used LG V20 F800L model a few days back. This phone i am using outside Korea so tried my Airtel sim. Phone accepts the sim (i guess not locked) but only shows 2G/3G not LTE. I even roam like drive-test to see if at any point it caches LTE signal but not. Airtel CC confirmed that they can see in their system that the phone and sim is 4G. i tried going to hidden feature but didn't find any option such as fieldtest to force it to LTE. I dont know if the phone is LG U+ locked or something else but want any help possible to push it to LTE.

Also i notice that this phone takes lot of time to connect to network even on 2G/3G, searches for long time when reboot or insert sim again.

Help me if possible.

If I'm looking at the right Airtel, they only support one LTE frequency, which your specific version of the V20 is not compatible with. This is a hardware incompatibility, and there it's nothing you or the carrier can do to get it on your phone. It is also somewhat limited in compatibility with the 3G bands, which could explain the connection time issue.
