UK Mobile Operators - O2 Continues to lead - vodafone coming back into contention
Whilst not purely focussed on business this article shows the continual battle between the operators in the UK for Marketshare.
There are a number of interesting points that I took away:
1) Tesco as an MVNO (Mobile Virtual Network Operator) is adding a lot of customers!
2) O2 has been the market leader in the UK for 3 years however it's ARPU per customer is much less than Vodafone.
