I have just signed up to a monthly plan and gone with the Samsung Galaxy S3 deal.

I have chosen to keep my wifes prepay number.

My 2degrees section is already showing the plan has been changed to a monthly plan.

As they will need to send out a micro-sim for the SG3 will this mean the old full size sim is deactivated a day or two before they send it out or will both be active allowing us to swap it over without any downtime?

Also anyone know the stock situation with the SG3 at 2 degrees?
