There has been a lot of talk about mobile wallets for smartphones, but this is not something you need in order to buy a single sms ticket from Västtrafik.
If you have a mobile phone contract or a registered cash card, you will still be able to buy and pay for tickets as usual by sms until 31 January.
From 1 February 2013, you will no longer be able to buy single sms tickets via WyWallet. Instead, you will need to register on Västtrafik’s website. Read more about registration for sms tickets here.
