HI we have MTNL no. for more then 20 year and has bean using internet service since 2006. recentley, i upgrabed modem to wifi and using since febrary 2016 as I encountered connectivity problen deu to modem. I have come to the conclusion that MTNL speed is one the best even the MTNL and airtel can not provide such service at such at cheap rate.
Net speed teast and serviece has improved has we areb encountering. dead line very less beacuse MTNL upgrading. their network is whole islamabad. their is a tricky part if you swish one thew hole ADL+ROTER wifi if will taken hafe.
