As we know, users of conventional dual-SIM phones have to select one SIM card for the reception of 4G LTE network, and then the other SIM card will automatically get a 2G connection. However, as the popularization of 4G LTE connectivity, 2G network is gradually fading from the stage. If 2G service gets shut down, the 2G SIM on traditional dual-SIM phones will fail to work. Taking this into consideration, growing phone makers are releasing phones with dual SIM that both have 4G LTE capabilities.
The latest one with dual 4G LTE support is rugged Ulefone Armor X. Without having to switch between two SIM cards, both cards can provide fast and reliable 4G network at the same time. So you can stay connected anytime and anywhere without lose of contact, no matter you are going on a business trip or leisure trip. Aside from this, the IP68 protected phone can withstand 1.5 hours of immersion in 1.5 meters of water or hours of ubmersion in the mud. Meanwhile, the solid TPU housing can protect the phone from drops, falls and scratches.
Besides the tri-proof features, the Armor X has a 5.5-inch 18:9 all screen display with HD+ resolution or the MediaTek MT6739 quad-core processor clocked at 1.5GHz paired with 2GB RAM and 16GB of internal storage. With 5500 mAh battery the phone can offer 2-3 days of normal usage with ease. Other specs include 5V/2A fast charge, facial recognition system, side-mounted fingerprint scanner, NFC for Google Pay, 5W wireless charging, and Android 8.1 Oreo as the OS.
