Don't forget, you could transfer the number to another prepaid carrier to save having to top it up as often. I don't know offhand if any carrier is particularly good value for North American roaming, though.

Me, I keep an album of dead SIM cards; since they fit in the slots for business cards, it's not hard to do. I've got 60-70 of them, although a disproportionate number are old Heyah, Vodafone DE, and TMO UK and US SIMs. Even so, a fun collection, and I'm sure I'm not the only one here with one.
