Best Rugged Smartphones (Unlocked) 2018

For those with a demanding job or lifestyle with constant exposure to environmental hazards, a rugged smartphone with military-grade protection may be the best option. A rugged smartphone is also a smart choice to use as a second phone when traveling. Ruggedized smartphone models meet military testing standards for protection against shock, water, dust, extreme temperatures, and vibration. They are water-resistant and can withstand submersion in shallow water for a limited time. When using a rugged smartphone, keep in mind that while these phones have been tested to military-specified standards, care should still be taken as glass screens can crack and drop test ratings do not guarantee you will always have the same results in the real world. Here are the best rugged smartphones for 2018 that are available unlocked. The following phones will work on GSM carriers like AT&T and T-Mobile but not CDMA carriers like Sprint and Verizon.

Ulefone Armor 2

Best Value Rugged Smartphone

Ulefone Armor 2 Best Value Rugged Smartphone

The Ulefone Armor 2 is part of the latest generation of rugged phones that offer significant upgrades over their predecessors without breaking the bank.

Also Consider: The Blackview BV8000 Pro is another recent phone with very similar specs to the Armor 2. We recommend the Armor 2 over it because the BV8000 Pro does not have a sealed charging port. Although the port is waterproof, it needs to be completely dried out before charging otherwise damage can occur. The BV8000 Pro also has a slightly inferior CPU and the exterior appears to be less rugged.


Rugged Smartphone with Superior Camera and Wireless Charging

DOOGEE S60 Rugged Smartphone

The DOOGEE S60 is another current-generation rugged phone that has similar specs as the Armor 2 and surpasses it in a few areas. Like the Armor 2 it is an IP68-rated dual SIM phone running Android 7.0 with the same CPU and memory setup and a fingerprint sensor. What differentiates it is the larger 5.2 FHD display with Gorilla Glass 5, the 21MP rear camera with a larger Sony IMX 230 sensor, 5580mAh battery, and wireless charging. Also the S60 has a traditional headphone jack while the Armor 2 requires a USB Type-C to 3.5mm headphone adapter cable (which is included). Unlike the Armor 2 it has a micro USB charging port. While DOOGEE is an obscure brand in the west, user reviews of its non-rugged phones have been favorable.

PROS: Good specs, great camera, big battery, wireless charging
CONS: On the pricier side for a budget phone

The display is a 5″ 720×1280 HD (300 PPI) screen with Gorilla Glass 4 that offers readability in sunlight.
