The simple answer to why our Mobile Operators still let Rogue WASP Operators persist is because it generates a great deal of revenue. For every WASP transaction the mobile operator gets a percentage of the money, the more transactions, the more money, its simple economics.
After countless consumer complaints Mobile Operators implemented a double opt-in for WASP services, launched block-all-WASP options, and forced all WASPs to be registered with WASPA (Wireless Application Service Providers’ Association ) in order for them to offer services, but instances still arise whereby consumers are being billed for services they have not subscribed to.
If you find yourself at the proverbial wrong end of the stick here is how to unsubscribe these services dependant on your Service Provider.
