 just follow my tips and fix your vi network problem 

1)lock band 3 for vi network 

2)contact vi customer care on Twitter for volte..its doesn't matter which device you are using. just tell them you are using samsung galaxy m30 .otherwise they told you that your device not supported vi volte service.. ..

enjoy vi high speed internet. 🤤

Simply give ur number and ask them to activate volte services...that's it

[Members_3Ofphlv]

yes .but normally,...if you called to customer care number  they don't listen you ,and telling you that your service is already activated/device not support. **bleep** bla ...so its better to go on Twitter. not only vi .airtel ,jio customer care support on Twitter is also good .

i already have jio 4g as my main sim ...but vi is for internet  ...at my area jio 4g is not so good .specially evening time .......but vi have good speed .because in my area 90% people are using jio/airtel  ..
