How to Make Calls with Your HTC One

By Bill Hughes

After your phone is on and you’re connected to your cellular carrier, you can make a phone call. It all starts from the Home screen. Along the bottom of the screen, above the Device Function keys, are five icons, which are the primary shortcuts. From left to right, they are

  • Phone

  • Messaging

  • Apps menu

  • Internet

  • Camera

To make a call, follow these steps:

  1. From the Home screen, tap the phone icon.

    The keypad screen appears. This looks like a stylized version of a touch pad on a regular landline phone.

  2. Tap the telephone number you want to call.

    Don’t be alarmed if you don’t hear a dial tone until you tap Send; smartphones don’t connect to a network and start a dial tone until after you dial your number.

    For long-distance calls while in the United States, you don’t need to dial 1 before the area code — just dial the area code and then the seven-digit phone number. Similarly, you can include the “1 and the area code for local calls. On the other hand, if you’re traveling internationally, you need to include the 1 — and be prepared for international roaming charges!

  3. Tap the green Call button (towards the bottom of the screen) to place the call.

    Within a few seconds, you should hear the phone ringing or giving a busy signal.

  4. When you’re done, tap the End Call button (the red button at the bottom of the screen).

    The call is disconnected.

If the call doesn’t go through, either the cellular coverage where you are is insufficient, or your phone got switched to Airplane mode. (It’s possible, of course, that your cellular carrier let you out the door without having set you up for service, but that’s pretty unlikely!)

Check the notification section at the top of the screen. If there are no connection-strength bars, try moving to another location. If you see a small airplane silhouette, bring down the notification screen and tap the plane icon to turn off Airplane mode.
