As bosses increasingly clamp down on Internet usage at work, a study commissioned by the mobile network found that a hefty one in four workers (26 per cent) have no access whatsoever.
Nearly half of respondents said they used their mobiles to log on while at work and 15 per cent admitted they were forced to log on in the bog.
The survey results didn't specify what sort of sites they were visiting, or whether any bogged in the bog.
Of those that were allowed online, just under a quarter of all respondents (23 per cent) said they were barred from 'social networking websites', while 11 per cent were banned from using web-based email.
And for seven per cent, Google was out of bounds.
A quarter of mobile users with Internet access on their phone admitted they were simply too gormless to know how to use it.
Despite tireless efforts by very well-intentioned mobile companies to encourage more people to go online through their mobile phones, nearly half (44 per cent) of the 2,000 people questioned dismissed mobile Internet access as simply "too costly".
"T-Mobile believes everyone has the right to access the web - even at work," said Richard Warmsley, head of T-Mobile's Internet on the Move.
