I am using vodafone last 10 year when we knows his name as hutch, I was happy when vodafone provide only 2g or 3g service. The problem start when 4g come in my network what a service wow downloding speed like I am using 2g service 50kb 60kb per second downloading speed and browsing marbolous if you open some website you can make maggie that time but still its wheel is running finally I can say the worst network if love to use internet.
And yes you cant use ur phone if you are in basement.
