Question

How do i switch data from afrihost to mtn and vice versa

Answer 1

You need to sign up for Afrihost Mobile Package, once you sign up it can either be added to an existing MTN Sim or Contract Package. Otherwise you may purchase it with a Sim. Then when your Data runs out you should be able to use your Data on the MTN Sim by removing the APN

Answer 2

Sadly you will need to change the APN each time unless you have a dual sim phone then you can set it up for each sim.
