I've subscribed to the mtn night plan for N25 and can browse with my itel Android smartphone but couldn't connect the internet with USB tethering on my laptop...

I'm wondering whether this plan DO NOT work using USB tethering or on any PC at all.

Also wondering if Airtel freebasic (which is the best app I've downloaded last) have blown away or corrupt the DNS settings (like Buhari govt.) on that phone.

Please help as I've spent whooping sum to acquire another itel tab, now I intend to make sure the old one becomes my internet modem.
