Like many, I changed to Cell C when they dropped the prepaid "BIS" package price, only to change to Vodacom about 8 months later due to endless connectivity issues with Cell C. I have a contract MTN phone (my old BB is just for chatting and surfing), but, honestly, I have better signal and service from Vodacom. As soon as my MTN contract is up, I'm ditching that sucker and getting myself a Vodacom contract!
