The Whatsapp Messaging service is free for all new registrants for 1 year from the date of registration - and there after it is $0.99/year (about R10 - or 10 South African Rands). South Africans can pay for this Whatsapp service after the 1 year period in either one of the two ways. 1) Via Paypal or 2) Via the Google Wallet. Paypal is not a very convenient method compared to the Google Wallet as South Africans can only top-up thier Paypal accounts (free to create) via FNB only and the process is not a pretty one. With Google Wallet, one can add any of the South African Banks' debit/credit cards and from there transfer money to the Google Wallet account. To pay therefor, open the Whatsapp Messenger app > go to Settings > go to Account > go to Payment info > click or tap Google Wallet > choose whether to pay from Paypal or from your bank a account (using your card's details) > follow the on-scree prompting depending on the method you choose. Ask any question you may have on this on this selfsame site.
