In order to preserve the 1.0 plan (the one that allows you two plan changes per billing cycle)
you will need to submit a ticket (or modify your existing ticket) to state that you want to
swap the phone numbers on your two lines of service.
This will move your original number from the E1 to the newly activated G4
and move the new number from the G4 to E1.
Once the swap is completed, it might be a good idea to restart your phones to make sure everything it working as expected. In the interim, you can continue to use both phones…you don’t need to keep them powered off.
If you don’t care about preserving the 1.0 plan and you are ok with moving the E1 to a 2.0 Refund Plan then there is another self-help way that can get you up and running faster. Let me know if you want information for that route.
