You can rely on the CROSSCALL SPIDER X4 in the harshest conditions. Its casing is made of solid plastic, ensuring the device will easily survive a 2-meter drop. Did you drop it in a puddle of water? The IP68 certified casing will keep the water out. Bobbing around for an hour at a 1-meter depth is child's play. Besides all this, you can also send texts and make calls with the SPIDER X4. This can be done on two cellphone numbers at the same time. Thanks to the dual SIM support, you can be reached on your business as well as on your private number.
