I have owned reliance sim for last 6 years I havegot no problem where I live but whenever I move to the other city I stated getting roaming . I dont get much network coverage in some areas but where I live I got full 3g network coverage . it give me good network in my areas.
I love the reliance and its not costly like the airtel and vodaphone it gives value for money it is very cheap in comparision to other network . I always get special offer from the reliance I always enjoy its service . and its customer service is very good .
