Sending Long SMS
An SMS is made up in what are called segments and each segment is 160 characters long. So if you are sending a lengthy SMS, it will take multiple segments which in turn will cause your cost to go up.
Please note 160 characters equals a segment, using 161 characers will cause your segment count to turn from 1 segement to 2 segments.
Please also beware that depending on your country and region the character length of segements may vary.
Using a Picture Attachment
Both SMS and MMS carrier fees apply which could drive up your cost of each SMS. When you send a picture message with text, you get charged $0.02 for the picture + the usual SMS cost depending on the length of the text.
What this looks like for you -
If you send out a broadcast, text, or automation with an image and the text portion is 2 segments it would look something like this:
"Hey Zach, this is Katie from business name, I just wanted to reach out to you today to let you know that we didn't receive your most recent payment. You can take care of that at www.callwidget.com/payment today or let us know if there is something we can do to help you get back on track."
You will be charged $0.0075 X 2 = $0.015 for the text portion.
If there's an image attached to this message, it will then cost $0.02 per message
Making your total cost per message sent $0.02 + $0.015 = $0.035
Please keep in mind that you might see some additional charges incurred:
- SMS Message Carrier Fees
- MMS Message Carrier Fees
- Phone Numbers
