MTN Nigeria recently advertised Nokia C3 that has been bundled with MTN services. MTN Nigeria offered one month free internet browsing to encourage Nigerians to buy the phone.
As a result of this, many Nokia C3 users keep searching for ways to configure their phones for them to enjoy the free browsing promo. Well, the promo ended on 31//12/2010.
If you own a Nokia C3, just text "Nokia" to 131. MTN will reply you with a message that the promo has ended on 31/12/2010, hence you will have to subscribe to MTN data plans for you to be able to browse with your phone.
