Hello
I am a new O2 customer and want to transfer my old number from WinSim to O2. My WinSim contract will expire at the end of this month. I informed them . When I signed up to O2 I selected the 'cancellation assistance' option.
What do I need to do to transfer my old number to O2?
Unfortunately there is no ticket panel for customers to ask the customer center at O2 this question.
Thanks
