Imposing traffic blocks and throttling mobile broadband usage could persuade consumers to switch to a new service provider, it has been claimed.
In a new study, VoIP provider Rebtel found that 60 per cent of mobile broadband users would consider switching if they are not allowed to use online voice calling and streaming services.
At present, a number of 3G mobile broadband providers prohibit the use of VoIP and other streaming services on a substantial number of their tariffs, reports ISPreview.co.uk.
And Rebtel believes this may encourage UK consumers to look elsewhere in search of a more comprehensive service.
Just eight per cent of survey respondents believed broadband providers are within their rights to block or limit access to certain services.
Andreas Bernstrom, Chief Executive of the firm, noted that traffic shaping is "a much debated topic within the telecommunications industry".
He said: "It has been brought to the attention of the Body of European Regulators for Electronic Communications who are investigating this further to understand the extent of traffic management practices and how it affects consumers' use of services."
