Got Questions? We’ve Got Answers.
Which devices support RCS OTP?
Any Android phone using Google Messages or an RCS-enabled OEM messaging app on a supported carrier will display the branded message. Devices that don’t support RCS will automatically receive a standard SMS OTP as a fallback to guarantee delivery across all networks.
Is RCS more secure than SMS?
Yes. When it comes to RCS vs SMS, a text message via RCS is generally more secure than traditional SMS. It sends messages over encrypted IP channels and uses verified sender identities, which helps prevent spoofing, phishing, and unauthorized interception.
Can the OTP message carry branding elements?
Absolutely. With RCS, you can include your logo, brand colors, and even interactive elements like buttons or quick-reply chips to deliver a consistent and professional user experience.
Do I pay twice if the fallback triggers?
No, you are only charged once—either for the RCS or the fallback message, depending on which one is successfully delivered. The system automatically guarantees cost efficiency without duplicate charges.
