Using the inReach Messenger Plus is easy. First, make sure you have an active inReach subscription. Then, turn on the device. When you're beyond cellular range, you can still use it to send text, photo, and voice messages. Just compose your message and hit send. Remember to keep the device charged regularly as the battery lasts for weeks but will eventually need a recharge. Also, since it has a durable design for extreme temperatures, it can withstand a bit of rough handling, but try to avoid dropping it from a great height. To maintain it, clean the screen with a soft cloth every now and then. This will ensure you can keep sharing your adventures for a long time.
