If you remove, replace, or deactivate your primary SIM, you'll need to re-authenticate your account. You remain signed in, and your chats stay on the device, but you cannot send or receive new messages or calls until you verify again.
Weak signal, no network, Wi-Fi calling, or airplane mode won't trigger re-authentication. If you remove your SIM while offline, Arattai will respond once you are back online.
Your devices are affected as follows:
- Primary device: You can view existing chats, but cannot send or receive messages or calls until you verify your SIM again.
- Android and iOS companion devices: These enter read-only mode. You can view existing chats, but cannot send or receive messages or calls, change settings, or link devices. If your primary device runs a version earlier than iOS 27, companion devices might remain functional.
- Web and TV companion devices: The app is locked, and chats are unavailable when the primary device is an Android phone or runs iOS 27 or later.
To restore access, insert your SIM in your primary device, open Arattai, and complete verification. Then verify each companion device using an Arattai OTP from your primary device. If your primary device still requires verification, Arattai will not send the OTP, and the companion device will prompt you to verify the primary device first.
This process protects your account and ensures compliance with security guidelines. Learn more about

How to restore access?
To restore access, insert your SIM in your primary device, open Arattai, and complete verification. Then verify each companion device using an Arattai OTP from your primary device. If your primary device still requires verification, Arattai will not send the OTP, and the companion device will prompt you to verify the primary device first.
Once Verified
Companion devices and web app sessions require verification to return to normal operation. Once access is restored, messaging resumes.
