Airtel is the first sim used in my life. It have good network coverage in my area for 3g and 2g. My family members adviced to change my sim due to high rate charges. I don’t know which plan is high on airtel.
I liked it very well by the pick pack in paper rechatge. We can select whick package activate in phone by entering listed code on behalf of recharge code.
I used a profitable internet pack which giving 250 mb for 25 rs by using favourable ussd code.
