# Add an SMS notification channel

To set up an SMS notification channel, input your country code and phone number, then click Save. You have the option to add multiple phone numbers to receive simultaneous notifications.

Please note that there is a cap of 100 SMS notifications per month. We recommend configuring SMS alerts only for high-severity issues related to your mission-critical smart contracts. This ensures you receive SMS alerts only for the most urgent matters.
