Frequently asked
How is SMS cost calculated?
Total cost = contacts × messages per contact × segments per message × cost per segment. SMS providers bill per segment, and a message over 160 characters splits into multiple segments — so longer texts cost more to send.
What is an SMS segment?
A segment is a 160-character unit (or 70 for messages with certain special characters). A message longer than that is split into multiple segments, each billed separately. Keeping cold texts to one segment controls cost and improves deliverability.
Does this include A2P registration fees?
No — this estimates per-message sending cost. A2P 10DLC registration has its own brand and campaign fees separate from per-segment costs. Budget for registration on top of the per-message total this calculator shows.
