⚡Quick answer -

Heyo virtual numbers are landline-based and therefore do not support SMS. You cannot send or receive text messages on a Heyo number. If a service offers an OTP (One-Time Password) via voice call, you can receive that automated call on your Heyo line. For regular SMS needs—bulk offers, marketing campaigns, OTPs, or transaction alerts—use our parent brand, MyOperator.

1. Why Heyo numbers don’t support SMS

Heyo issues virtual landline numbers. Landline infrastructure supports voice calls only; native SMS transport is unavailable. Consequently, no inbound or outbound SMS can terminate on or originate from a Heyo number.

2. Workaround: Receive OTP via voice call

Some services let you choose “Call me with the code.”

1. Select the voice call option on the service’s authentication screen.
2. Enter your Heyo virtual number.
3. You’ll get an automated voice call that reads out the OTP digits.
4. Enter the digits to complete verification.

Limitation: This method works only when the third-party service explicitly offers “call-based OTP.”
