Your code came by WhatsApp, not SMS? Why apps do it

Updated 7 November 2026 · The ReserveSMS team

In short

  • Some apps send codes by WhatsApp or Viber as well as, or instead of, SMS: Shopee, Careem and Mercado Libre among them.
  • Careem says WhatsApp is often quicker. Check WhatsApp if a text hasn’t come.
  • If you need a text, look for an SMS option on the code screen.

A code you were waiting for by text can turn up in a chat app instead. Some apps offer it as an option; some choose for you.

Apps that do it

  • Shopee: if no SMS arrives, it says the OTP may have come by Viber or WhatsApp.
  • Careem: you can choose WhatsApp or SMS, and it says WhatsApp is often quicker.
  • Mercado Libre: lets you choose a code by SMS, WhatsApp or phone call.

Why

Chat-app messages travel over the internet, so they can reach a phone where texts are slow, as Careem’s note suggests. The code works the same way wherever it arrives.

If you need a text

Look for an SMS option on the code screen, or a “send another way” link. A one-time number from ReserveSMS receives texts only: choose SMS with it. If an app only sends by WhatsApp, a number from us won’t get the code, and if nothing arrives within 20 minutes, the money goes back to your balance.

Never share it

A code by WhatsApp is still yours alone. See the verification code scam.

Common questions

Why did my verification code come by WhatsApp?

Some apps, such as Shopee and Careem, send codes by WhatsApp. Careem says it’s often quicker than SMS.

Can I get the code by text instead?

Usually. Look for an SMS option on the code screen. Careem and Mercado Libre let you choose.

Will a one-time number get a WhatsApp code?

Not one from ReserveSMS: our numbers receive texts only, so choose SMS.
