Mobile information and entertainment company WIN plc has announced it's working to improve Vodafone's services to mobile virtual network operators. Current UK MVNOs include Asda, Talk Mobile, BT Mobile, Truphone and Lebara.

The partnership enables new customers on Vodafone-hosted MVNOs to request a SIM by simply sending a text to a shortcode. WIN's SMS platform then manages a short dialogue with the consumer, obtaining and recording their name and address before the SIM card is posted directly to them.

This week's podcast is dominated by the results from the Interphone 'brain cancer' mobile phone research, although there's also time for Iain, James and Mark to talk about Google, Bluechipworld, Vodafone MVNOs, giffgaff, 3D mobile video, HTC's legal action and houses without fixed-line phones.

Vodafone has announced its annual results for the year ending 31st March 2010. Group revenue increased by 8.4% to £44.5 billion, with service revenue increasing by 8.9% to £41.7 billion. Group EBITDA was £14.7 billion, up 1.7%, and adjusted operating profit was £11.5 billion. European service revenue dropped 3.5% to £28.3 billion.

The company's proportionate mobile customer base is now 341 million, having seen 8.5 million net additions during Q4. Data revenue exceeded £4 billion, up 19.3%, with over 50 million customers now using data.

Talkmobile, which operates a mobile phone service on the Vodafone UK network, has launched an 'overdraft facility' for its Pay As You Go customers. The Lifesaver service allows Talkmobile’s prepay customers to borrow £1 when they run out of credit. This is automatically repaid when they next top-up, along with a 10p service charge.
