Telenor when was launched in India there main features were cheap call rates and internet rates. There plans were breakthrough in Industry but as time had passed the competition has increased.
The network coverage of telenor is dead I can hardly get signal in my home.The problem does not end there they have another problem of automatic activation of plans but they return money if cancel it same day.
There charges are now days as average and after launch of Reliance Jio they are out of competiton as any other telecom company.
In last my conclusion is that if you want only cheap rate and can sacrifice network coverage for it then go ahead.
