I have the same setup, Note 2 replaced my Thunderbolt (still have as a backup though). If you try to use the old SIM in the Thunderbolt, it won't work because it gets deactivated in Verizon's system and is rendered useless when the Note 2 was activated. The Note 2's SIM is now the only active one for that line, so you'll need the SIM card adapter to use it in the Thunderbolt to get service. You could try to carefully insert the Note 2's SIM in the Thunderbolt without an adapter, but it's difficult to make sure the contacts are properly lined up, so it's best to stick with using an adapter.
