How can I make samsung note 4(Olleh korean version) work in India (bandwidth error) ?

[AC Question]

My samsung Note 4 Olleh carrier
can't receive the signal from airtel
even if it does receive signal not more than 2 minutes

And Aircel sim was working well for 2 days and later couldnt

Looks like the bandwidth problem

Have you tried to replace the sim card? Have you verified that you are using the correct apn?
