As of February 1st 2013 there is new rules regarding buying sms-tickets with your cellular phone. This depends partly on the fact that EU and the Swedish Financial Inspection have passed new regulations, and partly that the mobile operators have stopped offering payment via invoice or prepaid cards.
To be able to buy sms-ticket for example at Västtrafik you first need to be registered on their website. Then you can choose if you want to pay by bank card, credit card or invoice.
The paid service that the four big telecom operators (Telia, Telenor, Tre och Tele2) have created, WyWallet, doesn't work to pay sms-tickets at Västtrafik or SL. As a customer at AllTele we can't use the other services in WyWallet, even though we use Telias net.
