UK based mobile operator O2 has confirmed plans to end support for its digital wallet by the end of March 2014, just 18 months since its launch in April 2012.

After 31 March, users will not be able to use their O2 Wallet or O2 Money Account Card any longer, including sending or receiving Money Messages, using the Wallet or card to shop, purchase train tickets in the app or top up their mobile.

O2 said in a statement that upon being launched 18 months ago, the O2 Wallet was one of the first mobile wallets around.

"Since then lots has changed for us, the market and our customers," the UK operator said.

"So, we’ve decided to close the O2 Wallet to give us time to look into new and better ways to help people manage their money on the move, both in the UK and abroad."

According to O2, users can either withdraw their money from their O2 Wallet account manually, or wait until after late March, when the mobile operator will do it for them via a bank transfer or a cheque.

The latest axing of service marks the second time within a year that O2 UK has put an end to a relatively new service including two of its flagship e-health services Help at Hand mobile monitoring service and its Health at Home telecare service.
