Calculating SMS Costs

It is important to know all of the SMS Pricing, however, it is reasonable to assume your highest SMS costs will be related to sending outbound SMS. For this reason, we will walk you step by step through the process of estimating the cost of an outbound SMS.

This article will provide you with the most recent figures for:

• UK to UK sending
• US to US sending

For pricing relating to any other countries please contact support@thesmartgrowthco.com.

Step 1: Calculate Your SMS Segments 

SMS messages are charged per segment. An SMS segment is made up of 160 characters. Once an SMS goes above 160 characters, you will be charged in the next segment bracket. 

Example:

1 Segment = 1 - 160 characters

2 Segments = 161 - 320 characters

3 Segments = 321 - 489 characters

Please bare in mind that the use of emoji's and other SMS features will increase the character count, resulting in less characters per segment. 

Use this software to calculate your segment count before sending your SMS.

After writing the message you want to send, copy the text message into the Messaging Segment Calculator and paste the copied text message into the Messaging Segment Calculator. See the "Number of Segments" to locate the number of segments.

Step 2: Calculate Your SMS Costs

Please note, these are estimates only**
