I hope you got everything switched over.
I've called them several times already to do SIM swaps to a micro SIM to use in the Lumia 710 for myself and family members. The conversation goes like this: "Hi, I have a new SIM that I would like to use." (they ask for the serial number, I give it to them) "Thanks! That's all I needed help with"
All lines I've called for either have T-Zones or $5 preferred phone first web (Web2Go) and not one rep showed any interest. A couple did offer to 'save me money' by switching plans so I tell them I'll think about it - I already know we're saving money on our current plan!
Castrol EDGE 5W-30 is my drug of choice.
