@NDesai is right. It's not possible to swap numbers between two plans while keeping both plans and both numbers intact. Variations of this request has been asked before and a moderator has said it couldn't be done: http://productioncommunity.publicmobile.ca/t5/Discussions/Switching-number-between-2-accounts/m-p/14...
Having said that, I see that only one of your plans is a promo plan (90 day 12GB $120), while the other is a currently offered in-market plan (90 day 6GB $120). There is one way to achieve a swap IF: 1) You're willing to give up the phone number currently being used on the promo plan, 2) you're willing to wait until the expiration of the in-market plan, and 3) you're willing to pay for another new SIM. You would simply wait until the in-market 6GB plan is nearly expired (1 or 2 days before payment due date), and port the number from that over to the promo plan. That would keep your promo plan with the number from the other plan, while cancelling the other plan which was nearly done anyway. The previous number you were using on the promo plan would be lost, of course. Then, you'd use a new SIM to activate a fresh 6Gb $120 plan, with a new number from PM. This SIM you would order and have delivered well before any of this porting and activating, so there would be no gap in service on either plan. Admittedly a fairly narrow set of conditions and an imperfect solution, but that would be the only way to keep three quarters of what you want (both plans, 1 out of 2 phone numbers).
