A commercial for T-Mobile's Web n Walk mobile broadband price plan has been cleared by the Advertising Standards Agency (ASA).
Complaints had centred around the fact that the provider's package featured a 3Gb fair usage policy promising no extra costs if the subscriber exceeded this data allowance.
Contract holders would, however, see their speeds reduced by T-Mobile if they broke the limit repeatedly.
This speed reduction would apply permanently if the user persisted, with only an upgrade to a contract offering a higher data allowance able to improve the connection again.
Among those who protested that the advert misleads customer was BT, which was suspicious that customers may have been forced to pay to upgrade once they exceeded the 3Gb limit - this was found not to be the case.
The monthly fee for the Web n Walk service currently stands at £15.
