I'm just back from Montenegro, I paid 10 Euro (R160) for 1,000Gb (1Tb) of Mobile Data for 30 days, I usually pay Vodacom R600 for 10GB - so Vodacom is roughly 400 times the price per Gig for those bundles!!
I would love to know how they justify that, 10 times - OK, 20 times - not really, but 400...
