Thomas Cook is running a World Cup promo for South Africa-bound football fans on pre-paid Sim cards, courtesy of a partnership with GO-SIM.
Buy a £20 Sim card and get £10 worth of airtime. Calls after that are 38p a minute and texts are 10p. Incoming calls from most places are free.
This works out at 80 per cent cheaper than say, Orange's international roaming tariff, according to Mobile Choice.
Even so, £20 doesn't sound like it would last so very long, especially in the unlikely event that England progresses beyond the quarter final - or even into the second stage. And £20 will soon dry up you want to sneak the occasional peek at your email - GPRS data in South Africa costs 95p per 100kb.
GO-SIM has got that taped: you can auto charge your account by credit, via the company's website. ®
