How can anyone looking for me buy phone plans and how much do they cost?

If the personnel of the Dive Center or even your loved ones look for you, give them the serial number of your SharkNet device (S/N) that you find in the back of the device (it’s strictly private: it’s not found in the web site!!).

They’ll be able to send you a SMS: if you are at the surface, the device will communicate them your position. If you are still underwater, it will do that a soon as you resurface.

…our underwater peacefulness often depends also by the one of those who remained at the surface.

To allow those who try to send you a position request and to see on the map where you are, the easiest thing is that they also download the Sharknet app for free and register as “family / friend”.

So in the section of the App SETTINGS >> CHARGE MY SHARKNET can load credit to send you the SMS requesting your position: just add the amount you prefer (eg € 20) through their PayPal account.

Each SMS requesting your position (or the position of any Sharknet of which they have the number) costs € 0.20; the cost will be deducted (and registered to be able to consult the expense history) from the credit charged on the App.
