1. if I have say 2k on my prepaid scon and I port to airtel, will that credit also move?
2. I call a ported 0733xxx from my airtel number, I will expect to pay ksh 1/- or will I be charged ksh 3/- it would cost to call scon from airtel yet I have no idea who is hosting the number I'm calling?

Wow, this is a good one. There's been nothing said about this bit.

My understanding of portability though not in the Kenyan market is you get to keep your telephone/wireless phone number regardless of who your wireless service provider is. Once your number is ported from say safaricom to airtel, airtel will be your new wireless provider and hence will bill you, not scom.

A lot of people prefer to keep their current telephone numbers due to a number of reasons..paying bills, school contacts for your kids, banking etc.

If airtel provides a better rate, then you can jump ship without losing your current phone number by changing service providers.

I have done it before.... number portability.
You only go to the mobile provider of choice and say you want to migrate....., fill in some forms and get a new sim card. The mobile provide will check with your current provider whether you have any legal obligations yet to be settled (post-paid clients only). You just wait for some 24hrs or there about and your current sim card loses network and you load the new simcard provided by the provider you are migrating to. That simple and it was free.

@BGL . . .why cant it be done automatically?e.g get a regulator company that monitors and switches you from one network to another while still using the same sim card?The filling forms part feels cumbersome to me.
