SMS Verification
Imagine you are setting up a dedicated WhatsApp Business profile to separate client inquiries from your personal life, but you only have one physical SIM card. Swapping physical cards or carrying two mobile phones just to register a second account is highly impractical. Travelers arriving in a new country face a similar hurdle when trying to coordinate with local contacts without exposing their home country SIM to international roaming charges.
OnayApp solves this logistical challenge by providing instant, temporary verification numbers directly on your mobile device. Available for both iOS and Android, our app uses a simple coin-based balance system instead of forcing you into expensive monthly subscriptions. You only buy the coins you need and spend them when you are ready to receive a verification code.
When you request a number, it stays reserved for you for approximately ten minutes, which is more than enough time to request and receive your SMS. If the verification code does not arrive within this window, your spent coins are automatically refunded to your balance. Popular choices for WhatsApp verifications include numbers from Malta, Kongo, and Umman for just one coin, or Niue for two coins, alongside options like Guatemala, Gine-Bissau, Haiti, and Arjantin for three coins.

Freelancers and small business owners often need to run WhatsApp Business alongside their personal profile on the same phone. Using a temporary number lets you register the business account cleanly without purchasing a second physical SIM card. This keeps your personal contact details private and organized.
When traveling abroad, staying in touch with local services or rental hosts is much easier through local messaging. Instead of paying high roaming rates on your primary mobile number, you can register a temporary account for your trip. This allows you to communicate freely while keeping your main line secure.
Selling items on public online marketplaces often requires communicating with unknown buyers. By using a temporary number for your verification, you can coordinate transactions without sharing your permanent mobile details. Once the sale is finalized, you can let the temporary line expire safely.
Download OnayApp, top up coins and receive your verification code in the app. No subscription, pay only for what you use.
