Can I call SMS and say i'm using a NAMU to get in first, but then switch to 800MSU later? I'm afraid 1st will get full. Sorry if this question has been posted before.</font>
You can absolutely do this, and some SMS agents will even suggest you do it in order to conserve the NAMU. Ask the agent to waitlist you for V and G. If G clears, great. You can then wait for V to clear, including calling in at the 72/24 mark. If V doesn't clear, fork over the NAMU and settle back. If it does, cancel the G seat, repocket the NAMU and settle back.
Good luck!
