DISCLAIMER: I have not tried this.
Step one: Buy something like this -
SIM Card Adapter - 3 Pieces - Apple iPhone 5S
(2) Go to a Verizon store and ask if they can activate a new nano-sim for you. You'll need to find a rep who has at least a little tech knowledge. You want them to understand wht you are trying to do.
(3) Put the SIM into the adapters and see if they work in your TBolt.
(4) Go find your "temp" phone ("rebound" phone?)
(5) You can then also use the SIM in your Thunderbolt as necessary.
