When and if that happens, you may soon realize that you wished you still had access to "How To" survival information. Just because you lose commercial AC Power, cell service, and internet service forever in a Doomsday event, does not mean that your smartphones and laptops are no longer useful.

How To Store Your Old Smartphones

It would be a significant oversight for any prepper to not include their current smart phones & laptops for survival information. Also, once you've loaded survival apps & videos, do not toss your old smartphones when you eventually replace them.

Just because they no longer have an active SIM card to use for calling, text messaging, and internet access, they still will work perfectly fine to access all of your offline pictures, files, and survival apps, so keep them as extra backups for your offline survival library.

Tip: When you do store your old smartphones and other electronic devices, store them in one of a large selection of military grade Mission Darkness Faraday bags to protect them against destruction from EMP (electromagnetic pulse) Doomsday events. Check them out as they make the best small faraday bags all the way up to large backpacks.
