I have had some challenges with airtime deduction on my phone since late November 2014, and the call centre agents at Vodacom have not been of any use to help me solve the issue. It got so bad, that I couldn’t even remember how I used my own airtime, and all I do is top up to save myself the agony of dealing with unprofessional agents and the read eye network.

I have sent all the “STOP” USSD instructions as received from Vodacom agents but the deductions never stop. I got frustrated to a point that I learned to live with the disability and allowed the grim reaper “Vodacom” to feed the monsters that ploy their empire.

So, whilst enjoying some “Star Trek: Discovery” on Netflix tonight I received one of the many SMS that pops up on my phone screen, and reads as follows:

Congratulations, you have subscribed to
—– @R5/day,.Billing will start in 3 days
or SMS “STOP to 42804 to cancel and opt-out!

I figured it all out tonight, that’s 6 years later. The stop messages I have been sending out were the activation beam these fraudsters needed to verify an active sim. Ignoring the message is one step closer to winning your number back and keeping your airtime.

According to fraud tracker, these syndicates, get numbers off the internet, social media links, and those “put your numbers here to market your business posts” to attract number submissions. Then they move onto their paid masters services to subscribe to these numbers and that’s how subscriptions pile up and they make money. Lastly, to confirm an active sim, they send out these stop and notice SMS to confirm an active sim.

This is how I cleared myself of 32 subscriptions that have been draining my airtime for the past 6 years, but I learned to recharge only when I need to make a call but long story short, 6 years of some painful headache from airtime fraudsters.


  • I sent an SMS containing “STOP ALL” to 31050
  • Then few minutes later, I received 32 SMS confirming different subscription cancelations. I was shocked.



  • Then I followed the USSD string on the SMS to *135*995# to check all subscriptions and unsubscribe in the future.

I also saw a direction on the WASP website about contacting Vodacom for a possible block on all future WASP subscriptions by dialing customer care (135). I will give that a try tomorrow.
