The share-dealing division of the bank decided to buy in the WAP infrastructure to free its own staff to concentrate on developing the mobile service.
Barclays' reliance on the service was revealed this week when Vodafone announced the launch of managed WAP gateways for the UK market. The bank was one of a number of Vodafone customers trialing the service in the UK.
The service, which takes care of all telephony issues and delivers IP traffic to the client, is aimed at medium to large sized business and Internet service providers. Vodafone is looking for resellers to market the service to smaller customers.
Philip Bungey, e-commerce director at Barclays Stockbrokers said, "This was a neat solution because it left us in charge of the applications."
Bungey revealed that the November launched had gone "brilliantly", enabling the bank to offer the same 15 seconds from quote to deal standard provided by its existing online service.
Eddy Murphy, senior analyst at Analysys, said developing a full WAP service in house "consumes a vast amount of effort". He welcomed anything that would reduce the time taken.
Murphy said WAP services would grow in popularity as users became more realistic about the technology's limitations, and as always-on third-generation mobile phones offered greater bandwidth.
