@Charles, I'll add a comment. I have 890 MBytes in my Orange  3g+ account which I paid for in advance but cannot access the services today.
 
3G+ ( evdo ) is very stable and has reasonably good speeds which it sustains well. Just when I was about to add a thread that Orange should consider offering SLAs as it
has been able to provide reliable services, booom, end of month and the service is down for almost 5 hours. So whether 1 Kshs or less, it matters not....  that's just hot air.
This amatuerism from Telcos has to stop.
 
One more thing, UNTIL Orange lodge the 1 Kshs Tariff with CCK and CCK publishes a Gazette Notice on the Tariff change, I'd never plan on it long term. Its a fanstastic move price wise, I hope they can pull it together and not rubbish the services in due process.
 
Rgds.
