I had a aircel prepaid phone in India. Seeing that they have 3G plan, I paid Rs900+ to get one month of 3G service. After purchasing it, the best download speed I could get was 120kbps. If I put a post paid sim I get 3mbps. But with prepaid sim 120kpbs was the maximum speed. Went to Aircel office at Salem, Tamil Nadu. Spoke with a person named Sabri tried he tried mutiple fixes but none worked. He agreed that the 3G speeds were not slower than 2G speed in the prepaid sim's. I asked him to refund the Rs900+, but they never refunded the money even though, it was totally their fault that the 3G speed was not available in the prepaid sims. They told there is no provision to refund the money and asked me to come mutiple time to the office and then I had to return to US so was not able to get a refund. Bad service from Aircel. Hope other check their service with smaller amount of money paid before commiting a larger payment with this company.
