I found telenor mobile operator as worst service provider, no network coverage most of the time, using telenor internet service but other service providers very bad speed and charges high and customer support nll. I will not suggest telenor for any new user. raised number of complaints. no use.
It does not deserve even a single star. they are trained to fool you saying there may be problem with your mobile. I am using lumia 730. Still I get issues. I find personally telenor as costly network provider.
