US & Canada. Prepaid in USD: you buy credits and usage draws them down. Outbound texts are billed per segment (160 plain characters, or 70 with an emoji or other special character; longer texts are split into 153- or 67- character segments). Carrier fees are passed through at cost, per segment, as the recipient's carrier charges them:
| Recipient's carrier | Local number | Toll-free number |
|---|---|---|
| AT&T | $0.0035 | $0.0035 |
| T-Mobile | $0.0045 | $0.0045 |
| Verizon | $0.005 | $0.005 |
| U.S. Cellular | $0.005 | $0.0045 |
| Other carriers | $0.0045 | $0.0045 |
Credits are drawn when the carrier accepts the message: failed sends cost nothing, fees included.
We file your A2P 10DLC registration for you. Registration fees (brand, campaign and vetting fees) are not part of these rates: they are billed on their own invoice, as Terms §4.3 sets out. Toll-free verification has no fee. Carriers usually review a registration in 3-7 business days, and you can text your own verified numbers the same day.
Free tier
The free tier needs no credit card:
- 100 live outbound SMS per month (10 per day)
- 1 phone number
- Live texts go only to numbers you've verified (up to 3)
- Unlimited sandbox: every endpoint, no caps, no card, no verification
- 30-day log retention: messages, the event log, conversations and API request logs older than 30 days are deleted daily. Opt-out and opt-in records, registrations, billing records and the audit log are kept as the Data Retention page says
Add credits to lift every cap, text anyone, keep your logs for the life of the account, and unlock live carrier lookups.
How billing works
Billing is prepaid. You buy credits with a card (from $5),
usage draws your balance down, and a call the balance cannot cover is
refused with 402 insufficient_credits rather than billed later. Credits
do not expire while your account is open. There is no platform fee and no
commitment; a month with no traffic costs nothing. Each month you get a
statement that itemises usage, paid from your credits.
Every response that consumes quota returns X-Quota-Remaining. When you run
out on the free tier you get a 429 with code quota_exceeded and a message
saying whether it was the daily or the monthly limit.
Want a hard ceiling? Set a monthly spend limit with alerts at the thresholds you choose.
Sandbox (test keys) is unlimited and free forever. It is never metered, never capped, and never requires a verified recipient; build the whole integration before you spend anything.
