I have been usingthis service from starting itself in my phone and I never get dissatisfied with the service of airtel and the signals will be at any place you travel you wont get any problem and the net also gives better service of airtel I feel much better with airtel than jio because jio service phones has many problems than airtel
I recommend you to take Airtel because its very useful and we wont get problem like jio users.The charges and billing are also payable for us
