Do I need to add country code +1 to mobile numbers?

1. If your account sends text message in 1 country only, for example USA, there is no need to add 1 in front of each number.

2. Our system automatically detects the area code and mobile number and prepares the number in proper format for successful sending.

3. In case you need to send text messages to different countries, then yes - adding country code in front of a number is a must.  Our system still detects numbers without country codes and adds country codes if needed, based on account country setting.
