Immediately, remove the battery from your phone. The sooner you remove your battery, the better your chance is of restoring your phone's function. Gently shake out as much water as you can from the phone and then place the phone in a dry area to dry out. Let your phone dry for a few days. If your phone does not work after it is dry, you will probably need to replace it; your phone's manufacturer warranty does not cover the replacement of a phone that has been damaged by liquid or has other non-manufacturer defects. If you have wireless insurance and an approved claim, your phone will be replaced at an authorized Cellcom location. If you do not have insurance you will need to purchase another phone.
