A few days ago, I posted that MTN data rates had dropped. Tests run by members of the MN team confirmed the reduction, and suggested that the new tariff was something between 14 and 20k per kb.
This morning, I spoke with an MTN official who confirmed that MTN has officially reduced its packet data rates from 60k to 15k per kb. The official also confirmed that this fee applies to GPRS, EDGE, 3G, and 3.5G usage.
This is a good move by MTN Nigeria. Now, GPRS users can browse at broadband speeds over 3G/3.5G when within coverage. In my own usage of the service, MTN 3.5G has delivered up to 600kb per second on a stable connection, and over 1mb in short bursts.
