Use Arattai on Multiple Devices - India
You can use your Arattai account on multiple devices by linking companion devices to your primary device. This article explains companion devices, how to sign in, and what happens when SIM binding requires re-verification.
What Are Companion Devices
Companion devices are additional devices linked to your primary device for using Arattai. Examples include:
- Web app
- Arattai TV app
- A second phone
Companion devices don't require a SIM and rely on your primary device for verification. The primary device is the phone with your registered SIM or active eSIM. Only one primary device is allowed.
You can review companion devices at any time under linked devices.
Sign In on a Companion Device
You can sign in to a companion device in the following ways:
- Scan a QR code: Scan a QR code from your primary device to link the device.
- Use an Arattai OTP: Sign in with a code sent to your primary device within the app. This code is not sent by SMS.
For detailed instructions, see Link a Companion Device.
Note: You cannot create a new account on the Web or TV app. If you do not have an Arattai account, you will see the message "No Arattai account found. An active Arattai account is required to use Arattai Web or TV."
What You Can Do Only on the Primary Device
The following actions are available only on your primary device:
- Change your phone number
- Delete your account
- End other sessions
- Link new devices
- Receive Arattai OTPs for signing in to companion devices
How Companion Devices Work With SIM Binding
When your primary SIM is detected and your account is verified, all your devices work normally. You can send and receive messages and calls on each one.
If your primary device loses its SIM or is unused for a period, your companion devices are affected.
When Your Primary SIM Is Not Detected
If you remove or replace the SIM in your primary device, or it becomes inactive, you must re-authenticate your account. Companion devices remain signed in and retain existing chats, but you cannot send or receive new messages or calls until you verify again.
How each companion device is affected depends on its platform:
- Android and iOS: The device enters read-only mode. You can view existing chats, but cannot send or receive messages, make or receive calls, change settings, or link devices.
- Web and TV: The app locks, and chats become unavailable.
The impact on companion devices also depends on your primary device:
- Android primary device: Companion devices are affected as described above.
- iOS primary device running iOS 27 or later: Companion devices are affected as with an Android primary device.
- iOS primary device running a version earlier than iOS 27: Companion devices may remain functional.
For recovery steps, see When Your Primary SIM Is Not Detected.
When Your Primary Device Is Inactive for 14 Days
If you do not use Arattai on your primary device for 14 days, all companion devices will require verification again. On the Web app, you will see the message "Your primary device has been inactive for more than 14 days."
To continue, open Arattai on your primary device and verify each companion device again.
Verify a Companion Device Again
After verifying your primary device, each companion device remains blocked until you verify it again.
- Ensure your primary device is verified. Insert your SIM, open Arattai, and complete SIM verification if prompted.
- On the companion device, select Verify again.
- Enter the Arattai OTP sent to your primary device. For the TV app, scan the QR code from your primary device instead.
If your primary device still needs verification, Arattai will not send the OTP. The companion device will notify you that it can't deliver the code and prompt you to verify your primary device first.
Note: You cannot verify your SIM from a companion device. If you attempt to verify on a companion device, Arattai will prompt you to verify on the primary device first.
If You Can't Access Your Primary Device
If your primary device is lost or broken, you can sign in on a new phone with your SIM. The new phone becomes your primary device, and all other sessions are signed out.
A companion device cannot become a primary device. If you select Can't access primary device on a companion device, Arattai will instruct you to sign out and sign in again as a primary device. Chats not included in a backup will be lost, as backups can only be restored on a fresh sign-in. A companion device stores only your latest 10,000 messages.
