No I doubt I never faced any problem with its network availability even when I used to go my home town where many people face network problem I got full speed internet connection and smooth calling , the best thing about it is that they don't charge you any extra for the data and calling they are very cheap and available almost everywhere even whenever I faced problem I call their customer service and they solved it in few Minutes . Jio never charge me any extra for anything their bill is very genuine and point to point . I can trust them for sure
