Getting started
Connect a provider, issue a key, send your first message — and meet the two defaults that quietly cost money if you miss them.

What each tier includes, how a "channel" is counted, and why your SMS fees never appear on our invoice.
What the subscription pays for
The subscription covers channel management on the platform. The messages themselves are billed by your own provider, at the rate you negotiated with them — the platform never touches, marks up or resells SMS traffic.
That split is the practical meaning of bring-your-own-account: one invoice from your provider for traffic, one small subscription here for the management layer.
The four plans
Sending volume is not capped on any tier. Plans differ only in how many channels you may connect, the submission rate, and how long the message log is kept.
| Plan | Price | Channels | Submit rate | Log retention |
|---|---|---|---|---|
| FREE | $0 | 1 | 10 QPS | 7 days |
| GROWTH | $19/mo · $180/yr | 3 | 50 QPS | 7 days |
| PRO | $49/mo · $480/yr | 10 | 100 QPS | 30 days |
| ULTRA | $199/mo · $2,000/yr | Unlimited | 500 QPS | 90 days |
Scope. Figures above mirror the current pricing page. Check the pricing page for what applies to your account, and treat this table as a summary rather than the contract.
How channels are counted
A channel is a provider account, not a phone number. Ten sender numbers under one Twilio account still count as one channel — and all ten join the platform's weighted rotation.
Change plan
Open Billing in the console
The current plan and its renewal date are shown at the top.
Pick a paid tier
Growth, Pro or Ultra opens a Stripe checkout. Free needs no checkout — it is the permission set you get by default.
Confirm the change
Upgrades take effect immediately; the new limits apply as soon as the payment clears.
Note. If a renewal payment fails, the account enters a grace period before it is downgraded to Free. A cancellation takes effect at the end of the paid period rather than immediately.

Connect your own provider account
Bring-your-own-account keeps the agreement, the sender reputation and the invoice with your CPaaS provider. Here is how to connect one, and what changes once you do.

Most senders never specify a from address, and that is usually correct. Here is when to override it.
