I never televerify mine any number..... its automatically got activated after network came
Its automatically came and in one sim out of 3.... network came after 7 days...Did network automatically came or you restarted ?
I've only one slot in my 4g phone, redmi note 4g, and I'm using it! Using my old samsung s duos 2 for my old airtel sim now..Trust you are using in Sim 1 only
