Sending texts requires the Business plan. Every plan receives them, and receiving is always free.

What works where
Texting is live on numbers in five countries.
A text goes to a number in the same country as your Allo number, so a French number texts French numbers. Swiss numbers on Allo are landline numbers, and a landline cannot carry text messages.

The one-time registration your number needs, and how long it takes
Automatic replies after a missed call
Never lose a lead to a call you could not take. Allo texts the caller for you, so they know you will get back to them.
- One for calls missed during business hours, for example “Thanks for calling, I’ll get back to you within the hour”
- One for calls that come in outside business hours, for example “Our office is closed, we’ll call you back tomorrow morning”
1
Open your number's settings
Go to Settings > Numbers, select the number, then open Automatic SMS reply.
2
Write your two messages
One for business hours, one for after hours.
3
Toggle it on
Done. It works from every device, because Allo sends the reply, not your phone.
An automatic reply is a message Allo sends on your behalf, so it needs whatever registration your country asks for: 10DLC on a US number, a Sender ID on a French one. See Set up texting.
Sending limits
The same limit applies in every country, and texts sent through the API count against it.
The limit counts segments, not messages, so a long text uses more of it than a short one. SMS rates explains how a segment is counted.
