What is this tool and how does it work?
How does the SMS Segment Calculator estimate cost and delivery length?. It checks every character for GSM-7 compatibility, highlights UCS-2 trigger symbols, visualizes concatenated segment boundaries, and can auto-normalize text to GSM-7.
Common Use Cases
- Reducing campaign costs in Twilio and GoHighLevel by removing UCS-2 trigger characters.
- Auditing long SMS copy with visual segment maps before launching automations.
- Validating segment previews inside CRM workflows to avoid billing surprises.
How to use
- 1.Paste your campaign message into the SMS inspector.
- 2.Review encoding, segment count, and highlighted UCS-2 trigger characters.
- 3.Use GSM-7 optimization and confirm the new projected segment cost.
Why use this tool
It prevents avoidable billing spikes by catching encoding issues early while keeping campaign copy private in-browser.
Technical Insight
GSM-7 supports up to 160 chars in one segment (153 concatenated), while UCS-2 drops to 70 chars (67 concatenated), increasing segment count and cost.
