For people who are prone to getting in situations that require them to get down and dirty with the world, or just for people who are more careless than usual, possessions and gadgets such as handheld devices need to withstand the punishment that comes with different and active lifestyles. When it comes to situations like these, Sonim Technologies Incorporated have made it their mission to manufacture and design mobile phones that are extremely resistant to the elements. All of their cellular phones have an IP (or International Protection) rating of 54 and above, each digit signifying the level and degree of dust, dirt, and moisture that the particular unit can resist.
