Credit with us never expires. You can send messages even just once a year.

After registration, you can generate an API key that will give you access to our API.

An SMS can be up to 160 characters long. If you want to send a longer text, it will automatically be split into parts of 153 characters (7 characters in each message are used for information that allows the text to appear as a single message on the recipient's phone). This is standard SMS behavior according to the GSM standard, the same for all providers.
