In one sentence, describe what the following article is about: Staying close to your gate will keep you apprised of any changes in your flight status. When scoping out a place to rest, stay within the concourse of your flight and do not leave the terminal. It can be helpful to keep your gate within your sight, so you can be close by if your flight gets back on schedule. You'll get the best rest possible if you can lie down. Look for benches or rows of seats without armrests in the terminal so you can stretch out and rest most comfortably. Be sure not to block any seats that are set aside for handicapped passengers. In the absence of a good bench or seat, look for a corner out of the way that's carpeted. The cleanest spots will be those without high foot traffic. Laying down a scarf or jacket can provide a nice barrier between you and the ground. Be sure not to lie down in main walkways or areas of high traffic. You don't want to block access to anything, and you'll get better sleep if you're not disturbed. Seek out quieter spaces between gates or near the food court to catch some Zs. The key is finding an area that isn't overly loud but is also not isolated. While prayer rooms, yoga areas and other less-frequented airport rooms can seem like good sleeping spots, you're more likely to be a target of theft if there is no one else around. Choose a sleeping spot away from the windows where natural daylight can keep you awake. Strive for a spot that isn't underneath a bright ceiling fixture either. Corners and laptop-charging areas are often dimmer and therefore better for sleeping. Many newer airports, particularly international ones, have areas with sleeping pods or loungers for passengers in transit. Locate the airport customer service desk and ask if they have any such facilities. These are often available for free or a nominal hourly fee. Going to another concourse or terminal is risky if your flight is only delayed. It's best to use this strategy on a long layover for a scheduled flight. Many airline lounges provide facilities to shower, eat and rest. If you have a long layover, it can be worth it to purchase a day pass to the lounge where you can sleep in a comfortable recliner. Most of these passes cost at least $50, and the lounges are typically only open to passengers who hold a same-day ticket on that particular airline. Some airline credit cards include perks, such as free lounge passes. If you're a frequent traveler, this might make sense for you.
Summary: Stay close to your gate. Locate rows of seats without armrests. Lay a scarf or jacket out on a clean, carpeted area if necessary. Find a quiet place that's not isolated. Seek out somewhere dim. Ask about sleeping facilities or loungers. Purchase lounge access if possible.

In one sentence, describe what the following article is about: If you can successfully make a call with another carrier's SIM card in your phone, your phone is unlocked; however, if you can't, the phone is carrier locked and you'll need to talk to your carrier about unlocking it. Before getting a new SIM card, figure out which size of SIM card your phone will use. You can consult the phone's manual, or you can research the phone model online. While this process will vary from phone to phone, doing so will usually entail pressing and holding your phone's Power button, then pressing a button or sliding a switch to turn off the phone. If your phone has a case on it, first remove the case. You'll most likely have to consult your phone's manual or look online to see where the SIM slot is if you don't already know. On iPhone, the SIM slot is either on the right side of the phone's casing (iPhone 4 and up) or on top of the case. Android phones vary their SIM slot locations, but you'll often find the slot on a side of the casing or under the battery cover. On some phones, you'll simply need to pull the card out; on others (e.g., iPhones), you'll need a paper clip or SIM removal tool to insert into a small hole next to the SIM slot. Be sure to reference the positioning of the original SIM card in order to ensure that you don't improperly insert the card. You'll do this by pressing and holding your phone's Power button. Once again, this process will differ from phone to phone: open your phone's calling app, type in a number, and press the "dial" button. If the phone call goes through, your phone is unlocked and should be able to accept any hardware-supported SIM cards from other carriers. If you are unable to make the call and you're certain that the number you're calling is valid, your phone is locked.
Summary: Buy a different carrier's SIM card or borrow one. Power down your phone. Locate your phone's SIM slot. Remove the SIM card from its slot. Place the other SIM card in the phone. Turn the phone back on. Try to make a call.

In one sentence, describe what the following article is about: If you sleep with unkempt hair, it will only become worse and more entangled in the morning. Simply run a comb or brush through your hair to reduce knots and tangles. If you take nighttime showers, it is a good idea to wait until your hair dries before hitting the pillow. You can either blow dry your hair, or wait for it to air dry. This will prevent you forming a crazy bed head look that is hard to manage the next morning. This will keep your hair from forming any cowlicks and give you nice, even waves for a casually-messy-but-polished look. Be sure to wear your braid and hair tie loose so you don't damage your hair. If you loosely tie your hair in a bun with a soft scrunchy, you can avoid any tangles or hair messes the next morning. As soon as you wake up, release your hair and you will be left with an effortlessly chic look. Using a silk or satin pillowcase reduces some of the friction between your pillow and hair. This can help you prevent bed head and damage to your hair.
Summary:
Brush your hair before you sleep. Dry your hair before sleeping. Sleep in a braid. Try wearing a bun to bed. Sleep on a silk or satin pillowcase.
