International roaming is probably the service feature that has the greatest value for international users of mobile telecommunications. It will enable customers of MTN Nigeria to make calls to and from other countries, across scores of GSM networks worldwide. Customers in Nigeria will thus benefit from the many roaming agreements already reached between the world’s GSM operators. Visitors to Nigeria with a GSM account held outside the country will also be able to use their phones here during their stay.
