Is my number supported for text and voice?

We support most networks worldwide for text and voice notifications. However, there are a few exceptions. If you try to verify your mobile number in the SIGNL4 app and you get a message that it is not supported, please contact us through the chat and leave your number and carrier.

Here is a video on how to configure text and voice notifications:

There are countries like India where you explicity need to confirm to receive text messages (as our messages are regarded as marketing). Please refer to the respective regulations and related government pages. Before you opt-in for text messages you won't be able to receive our phone number validation text message.
