All,
Do you know you can add 5 celtel numbers to your celtel line and make calls to the five no. as cheap as 20k per second.
To add friends and family number on celtel line.
Dial *141*2*number, then pam sign

Example *141*2*0802xxxxxxx#
The first 5 no is free while additional one cost 50 each.

To check number added, *141*2#

To delete, *141*3*0802xxxxxxx#

I've tried this several times and it doesn't work, Celtel na yeye network. I wonder why people are still using it

It work for me one time. May be you hven't migrate to simply special.
