EBay members will be sent SMS alerts when they're outbid on an item, if they win an auction and when an auction ends. The 'outbid' message will contain a mobile WAP link where users can increase their bid.
The service, which costs 25p per message received, will also alert sellers if a buyer fills out purchase information at checkout and if they get feedback.
Users can turn off alerts at night. EBay members can sign up to the eBay Anywhere service at ebay.volantis.net/anywhere.
