We use email-to-SMS services to send reminders (see the list of supported networks).
Some mobile providers require you to activate an email-to-SMS service with them before this will work. If you're using a supported network and not receiving reminders, please contact your provider and ask if you need to activate the email-to-SMS service for your account.
If you need to whitelist our reminder email address with your provider, it's firstname.lastname@example.org for SMS reminders.
