• As rain may enter inside your pocket/bag, it is very useful to put your phone inside a plastic bag. Make sure there is no any tear or whole in plastic bag to prevent the water from entering.
• Do keep a silica gel inside to keep the device moisture free.
• If you are strolling or using your bike, place your phone in the inner layer of your raincoat pocket. Or it could be inside your waterproof bag.

Waterproof cover.

• Instead of simple plastic, you can even buy special waterproof cases/cover to make it safe for continuous use in the rain.

• Put your phone in a safe place and use it hands free or with earpiece to save it from water.

Switch off if it is wet.

• If a mobile is wet, you should immediately switch it off or take out the battery. Then leave it for a day till the phone (along with inside chip circuitry) gets dry.
• Do not use any heating equipment or charger.
• If its heavily soaked in the rain, you should submerge the phone, battery and SIM inside a bowl of rice for a day.
