News emerged that Cell C and MTN would finally implement double opt-in systems for wireless application service providers (WASPs).

Vodacom rolled out its double opt-in system two years prior. According to Vodacom, the double opt-in procedure cost a 33% reduction in WASP revenue, but the operator said it was worth it for the dramatically reduced fraud complaints.

Along with unveiling its new double opt-in systems, Cell C and MTN also launched ways for their users to manage their content subscriptions.

Previously subscribers needed help preventing a WASP from charging their cellular accounts or unsubscribing from premium content services without contacting the WASP.

Vodacom also has a method to manage WASP subscriptions through an SMS command to unsubscribe from everything.

The various WASP subscription management options of South Africa's mobile operators are as follows:

How do I cancel my Cell C subscription? 

Using the USSD string *133*1#, subscribers can block all existing and future content billing.

How do I cancel my MTN subscription?

MTN also offers a USSD string (*141*5#) to manage premium content subscriptions, but unlike Cell C's, it doesn't block all future subscriptions. Instead, users select which services to unsubscribe from.

How do I cancel my Telkom Mobile subscription?

When asked about its self-service options for WASP subscriptions, Telkom Mobile said it does not allow WASPs to charge for subscription services. Contact the Telkom Mobile call center to cancel a subscription. Call Telkom Mobile on 081 180 or email [email protected].

How do I cancel my Vodacom Mobile subscription? 

Vodacom users can unsubscribe from all WASP services by sending "STOP ALL" to 30333.

Should you be subscribed to WASP services, you should receive the response, "Your Vodacom request to delete all WASP service has been logged." According to Vodacom, you should receive the format's messages, "You have been unsubscribed from 'SERVICE' with effect from 'DATE.'’"

If you are not currently subscribed to any services, you should receive the somewhat confusing response, "Your Vodacom request to delete all WASP services has been unsuccessful; please call Vodacom Customer Care on 082111".

Vodacom said it is working on changing this message to say that you are not subscribed to any WASP services.
