— Keep your phones and tablets dry and charged. If power is interrupted, having a plan to keep your devices charged will give you peace of mind that you can stay connected during the storm. Portable chargers with the capacity to charge multiple devices and car chargers are good choices.

— Save battery life. Using the Power Save Mode on your device can help you get more connected time on your device. Power Save Mode limits some of the device’s performance to conserve battery life.

— Keep informed. Download your local news or favorite weather apps to keep informed of conditions in your area.

— Minimize mobile phone use when possible — AT&T recommends you keep lines open for first responders. Limit your calls and social media use to the most important ones. If there is severe weather, chances are many people will be attempting to place calls to loved ones, friends and business associates. And text rather than call; texting uses fewer resources and helps keep the lines open for emergency calls.
