Terms of service
Last updated 7 November 2026.
1. The service
SendSMSOnline is a web service for sending SMS online to 227 countries: paste or upload phone numbers, write one message, see the exact price per country and send it from your browser, paying per message from prepaid credit. These terms apply to the website, the workspace and the API at sendsmsonline.cc.
2. Your account
You create an account with an account key made in your browser. The key is the only way to sign in; we keep a fingerprint of it, never the key itself, so we cannot show it again. Keep it safe and do not share it.
You are responsible for what is sent from your account, from the workspace or with your API keys.
3. Credit and prices
You add credit by topping up from $40. Credit is shown in US dollars, has no expiry date and is used to pay for messages. Credit cannot be withdrawn or exchanged back to money.
Each destination has its own price per message segment, listed on the pricing page and shown in the composer before you send. The price that applies is the one shown when you confirm a send.
A first top-up bonus, when offered, is added as credit and used like any other credit.
4. Sending messages
Send only to people who gave you their number and expect messages from you, and only content allowed by the acceptable use policy.
Campaigns leave at up to 300 messages a minute. Delivery depends on the receiving networks; delivery reports show what happened to each message.
We may pause a send or an account that breaks the acceptable use policy; credit already used for messages that left is not returned in that case.
5. Refunds
Messages that fail are refunded to your credit automatically. Scheduled sends canceled before they start are refunded in full. The refund policy has the details.
6. The API
API keys open after your first credited top-up. Each key is shown once. Requests are limited to 240 a minute per key; the documentation describes every endpoint.
7. Changes
We may improve the service and update these terms. Changes to prices apply to sends confirmed after the change; the changelog lists changes by date.
8. Contact
Members open a ticket from Support in the workspace. We answer in the same thread.
