Hi Wayneburg,
Hmmm...a rather informative post. Thanks for taking the time to jot down the key issues (a couple of which I was unaware of).
FWIW I've photocopied the card and place a lightweight paper copy in my wallet and used a label maker to create labels which have been in my kits since I first got my card about a year ago, additionally, I placed a label with the calling # and PIN around the AAA battery in my ARC AAA light EDC. This has been duplicated for family members.
Didn't really do much research when I p/u the card, just went to Costco and got a Preppaid Rechargable Phone Card by MCI, initially rated for 670 minutes (dark blue and orange front and the back is black & white. I concur fully with your comment about them being worthwhile additions to the kits.
My perusal of the fine print revealed that it is initially valid for 2 years from date of purchase, and can be renewed apparently ad infinitum.
Don't know how this rates on your grading scale & I'm curious if you've any comments regarding this card. If need be, we can take it to PM.
On the whole, my hat is off to you for bringing more knowledge to light. I've seen a couple of threads that touched on these cards, but never a thread dedicated to them. Thanks.
Regards,
