Is it possible to get a years data for R310

Well yes but you will need a dual sim phone

u will need a dual sim  phone telkom mobile and a cell c sim card

You will need an Telkom mobile internet starter pack data bundel *147# (u don't need to buy a new starter pack its in bundle options)
R99 for 2.4 gigs
You will get 200 mb a month for internet

and now this is were cell c comes in

whats app bundle for the month is R5 so whats app works when u run out of data (R60 a year)

so far R160 a year

now u want to update and download apps (200 mb wont enough)

so u take a night bundle 1 am to 5 am

For R12.50 u get a 1Gig data so its R150 a year for 12 gigs

so this costs u R310 a year altogether

so u get whats app bundle for year even if u don't have date u can chat
and u get 200mb data a month bundle o use for surfing the net
and a 1 gig for updates and new apps

so total is 14.4 gigs a year for just R310 what a deal

and cheaper then a blackberry R720 a year
