Electronic devices (cell phones, computers, etc.) can sometimes be salvaged after exposure to water, heat, or extreme conditions during an emergency. If the device itself can’t be salvaged, the data stored on it can possibly be restored. This is especially important if the data was not backed up at a safe offsite location.
Salvaging a Wet Cell Phone
Remove battery as soon as possible! Do not turn the phone on, even just to test!
If the cell phone has a removable SIM card, remove it. Data recovery software and data recovery services are available to recover data from damaged storage media. Follow the directions under Flash Drives if you attempt to recover the card yourself.
Remove battery covers and any shell parts that are removable.
If device was in contact with salt water, mud, sewage, or other contaminants, rinse thoroughly in clean water.
Drain out water, and air dry for a while. It is OK to use a fan, but avoid applying heat, as with a hair dryer on any heat setting and avoid too strong an air blast – it may blow water deeper into sensitive parts.
Avoid extreme heat that may melt or damage components.
Seal the phone in a container with a canister of silica gel desiccant, or bury it in a sealed container of dry, uncooked instant rice for 2-3 days. Do the same with the battery and flash memory card.
Once phone is thoroughly dry inside (may be difficult to determine) reassemble phone, replace flash memory card (also dried) replace battery and test. If phone does not work remove battery as quickly as possible and try drying again. Also, battery may need to be recharged.
In a disaster, text messaging service is sometimes restored before full voice service.
