Many users have recently noticed that WhatsApp Web keeps logging out automatically every few hours.
At first, many people thought it was a technical problem.
However, reports suggest that the issue may be linked to a new system introduced in India from March 1, 2026.
Under this change, a WhatsApp account may need to remain connected to the physical SIM card in your phone.
If the SIM is removed or inactive, the web session may automatically log out.

What Is the SIM Binding Rule?
Earlier, WhatsApp worked on a one-time verification system.
Users simply entered their mobile number and confirmed it using an OTP.
After verification, the account could be used on multiple devices such as WhatsApp Web or desktop.
Even if the SIM card was removed from the phone later, the web version usually continued to work.
However, under the new system linked to the Department of Telecommunications, the app may periodically check whether the registered SIM is still present in the main phone.
If the SIM is removed, replaced, or disabled, the account may be temporarily restricted.
Reports suggest that this verification check could happen every few hours.
Why the Government Introduced This Change
According to officials, the main aim of this step is to reduce cybercrime and online fraud.
Authorities say that many scammers create WhatsApp accounts using Indian phone numbers and then operate them from other locations.
This makes it difficult to trace them.
By linking every active account to a KYC-verified SIM card, it becomes easier to track suspicious activity and hold users accountable.
The government believes this move will help improve security as cyber fraud cases continue to rise.
What Changed After March 1, 2026
The biggest change is that the presence of the SIM card may now be checked regularly.
This may affect people who frequently use WhatsApp Web or desktop versions.
If the SIM is not present in the phone, the web session may log out automatically.
Users may also notice stricter rules for features like Linked Devices and Companion Mode, especially on devices that do not have a SIM card.
How to Avoid Frequent Logouts
There are a few simple steps you can take to avoid this problem.
Make sure the WhatsApp account is registered with the same SIM card that is currently inside your main phone.
If you have recently changed your number, check that your account details are updated.
Also keep the app updated to the latest version.
If you regularly use WhatsApp Web for work, it is best to keep your phone nearby and ensure the SIM card remains active.
This will help prevent repeated logouts.
