Loop mobile, as per I know loop is first company which start offering lowest call rate to customer like 10 paisa per minute which is very help full for people.
They offer various promotions like dis ka gang. In under this promo loop receive lot of unexpected service subscriptions.
About loop network, yes it is little bit hectic. Lot of people facing the network issue but raraly not regular. Overall network is ok but not too good they need to improve the network strength to make business up.
About loop customer support , yes it is very good. You never expect they deserve this. Very polite & good knowledge people which have very good respond to a customers.
This is my overall experience about loop mobile. Which I feel till.
