Telenor sim is not good because of so many resoans the one of them is internet speed which everyone needed not only for surffing but also for video call , whats app and banking etc. Normally people want lower price sim which recharge plan are not low very low or free. Just because of that this sim is most wanted but its call system also very bad I am use this sim one most only luck by change calling will completed but at the and it is chip so keep enjoying and connect with your friend with the best net work
