Plan

[RPB2]

I have the $15.00 plan with 100 minutes. I see there is a new $15.00 plan with unlimited talk & text. I would like to transfer to the new plan, do I need a new SIM card or can I just go ahead & make the change

No new sim card required. Just change your plan effective next renewal. Note that the new version does not include 250MB of data that you get now.

@RPB2 

no new sim required.  Your sim will work with all plans here

please be aware the new $15 plan does not include any data at all.  If you need data, you will need to buy data addon and they have a 30 days expiration

and when you make plan change, if you don't need the new feature yet (unlimited calls), select Change on Renewal to schedule the change on your renewal date instead of Change Now.  With Change now, the change will be immediate and no partial refund for the unused days of your current cycle
