After some clarification on this - on the XT network if you change your number, can you keep your plan?
eg assuming the plan is no longer available, and that its prepaid, is it possible to keep the plan in any of these scenarios?
1. I have a number currently on the plan and i want to port over an existing number from another network
2. I have a number currently on the plan and i want to change it to an existing number on XT
3. I have a number currently on the plan and i want a newly generated 027 number

Cheers
