Problem: Write an article based on this summary: Download and install Google Hangouts and the Hangouts Dialer. Sign up for a Google Voice number (optional). Connect to a wireless network. Open the Hangouts Dialer. Dial the number you want to call. Give out your Google Voice number to receive calls for free.

Answer: You can use Google Hangouts and the Hangouts Dialer app to make free calls to any number in the US and Canada whenever you are connected to a Wi-Fi network. If you have a Google Voice number, you can use Hangouts to receive calls for free as well. You will need both Hangouts and the Hangouts Dialer app in order to make calls for free. You can download both apps for free from the Google Play Store.  These apps will use the same Google account you already have associated with your Android device. If you're using an iPhone, you'll need to log in with a free Google account. There is no Hangouts Dialer app on the iPhone. All calls are made through the Hangouts app. A Google Voice number will allow you to display the number as your outbound caller ID. This isn't required, and "Unknown" will be displayed as your caller ID if you don't sign up for one. You can create a free Google Voice number at google.com/voice. It will automatically be associated with your Google account. You can also use your SIM card number as your caller ID if you don't have a Google Voice number. This number is verified by your installed SIM card. You can use the Hangouts Dialer app to make calls as long as you have a data connection. This can be Wi-Fi or it can be your cellular data connection. In order to ensure that the call is truly free, connect to a wireless network so that you aren't using your mobile data plan. The app will open a dialer very similar to your regular phone app. You can't start a Hangouts call from your contacts list; you'll need to start it in the Hangouts Dialer app. If you're using an iPhone, tap the Phone tab at the bottom of the Hangouts app to place a call. The Hangouts Dialer will allow you to reach most numbers in US and Canada for free, as long as you are in a country that supports Hangouts calling.  If you are calling internationally, even if dialing a local number while visiting that location, you may need to add a "+" plus the country code of the number you are trying to reach. If the call costs money, the rates will be displayed your Google Voice account will be charged if you accept. You can add money to your Google Voice account at google.com/voice#billing. You can use the same page to check rates for calling various countries. If you have a Google Voice number associated with your account as well as the Hangouts Dialer, you can receive calls at your Google Voice number. If you're on Wi-Fi most of the time, you can use this to make most or all of your calls for free without eating into your minutes.


Problem: Write an article based on this summary: Manage your contacts. Set up e-mail addresses. Configure other settings.

Answer: Enter the contacts manager on your phone and add new contacts that you will be communicating with on your phone. If your phone is Wi-Fi capable, you will be able to receive and send e-mails through your phone. Set your e-mail up with your phone’s e-mail app. Personalizing settings, like wallpaper, ringtones, alarms, and that sort of thing, can be done last. This usually takes the most time as you will be figuring out which sounds and wallpapers work for you.

Problem: Write an article based on this summary: Take levothyroxine 30 to 60 minutes before breakfast. Wait 4 hours before taking a medication that affects absorption. Wait at least an hour before eating foods that interfere with absorption.

Answer:
You need to take your medicine on an empty stomach, so first thing in the morning is the best time. After taking it, wait at least a half hour to eat. Food and coffee or tea will interfere with absorption. These include antacids, cholesterol medications, and any medications or supplements that contain calcium or iron. Additionally, you can only take levothyroxine 4 hours after taking any of these medications. If you woke up in middle of the night with an upset stomach and took an antacid, make sure you wait long enough before taking levothyroxine. Soybeans, walnuts, dietary fiber, and foods that contain calcium, such as dairy products, can affect absorption. To stay on the safe side, try not to eat these foods for at least an hour after taking your medicine. If your doctor finds that your body isn’t absorbing levothyroxine properly, they might suggest you avoid foods like walnuts and soybeans or eat them later in the day.
