Britain's largest mobile broadband operators have struck a deal to promote greater transparency for customers.
Orange, T-Mobile, Vodafone, 3 and Virgin Media are just some of the operators that have signed up to the Mobile Broadband Group's (MBG) Principles of Good Practice.
Features of the code include making coverage information available via the internet, offering clear technical support on realistic speeds and supplying details on roaming charges.
Chair of the MBG Hamish MacLeod said: "Mobile broadband is proving very popular, as customers begin to appreciate the benefits of having ready access to so much information while on the move.
"It is in everyone's interests that market growth is based on customers being well-informed about the choices they make."
Mr MacLeod went on to say that the MBG's guide would help develop consumer understanding of the technology.
Research published by Telecompaper last month revealed that sales of mobile broadband devices in Europe increased to approximately 10.5 million in 2008.
