Everyone’s done it; and while mobile phones are designed to withstand the occasional fall, a lot of bumps and bangs could result in a broken phone. If you are a heavy-handed cell phone user than a rugged mobile phone may be for you. The Sonim XP3 Quest mobile phone from Sonim Technologies can be submersed in water for 30 minutes, survive extreme heat, is impervious to dust and micro particles and is impact proof, which means it can withstand drops on concrete. But the durability doesn’t come cheap, it sells for $525 without a plan. A cheaper alternative is the Motorola Brute phone, it has rubberized molding and is military certified to withstand blowing rain, dust, shock, vibration and temperature extremes. The Brute costs $119.99 with a two-year plan from Sprint.
