I purchased a aircel pre paid sim card worth rupees 129 and I am using this sim card from last two months. Aircel company gives appreciable network all over the mumbai. Call cost of aircel company are two low so we can have a free talk with our friends and relatives with very low charges.
Internet speed given by aircel company is very good. You can also access internet in roaming areas without any charges, also incoming is free in roaming areas. I liked the facilities given by aircel company.
