Yes, Plivo offers default OTP templates, but you can create custom templates that support brand name, OTP, and OTP expiry variables from the console. Custom templates can be localized for specific languages using the 'locale' parameter when creating sessions. For assistance on this, reach out to our support team.
Please note that custom templates have to be created and used via the Locale parameter itself. Custom Templates are not an independent offering to the Locale offering, they are fundamentally the same.
