Keep them as a backup.

yeah, backups are always nice. plus, it'll save you a trip to the t-mobile store to get a new one if an unfortunate occasion would come up and your device fails to read your current sim card. I've had to do a sim swap twice in a little over a year.

just call t-mobile customer care or tech support and ask them to do a sim swap, you'll just have to read off the numbers to them.

Keep them in the blackberry boxes for storage.

As long as they are still valid. Sometimes they ship them with a device but they are assigned to the device already. Then after a while when not used they are kicked out of the system and no longer valid. Strange, but it's happened to me with several brand new sims.
