I have given Airtel prepaid sim card from one of my employer. It was worst experience ever. I had to recharge that sim first then my employer reimburse later. I spent too much money in recharge with it but the company deducted too much charges for the calls wether it is local or national. Major problem with this connection its poor network whenever I was on official conference call it always lost the network. that was true bad experience with the connection. Customer care is unable to resolve yout issue. Use this sim card only if you have lots money to waste. God Bless!
