You might experience some issues, like chatting with people that have an outdated WhatsApp version from WhatsApp Web/Desktop beta, and Portal. Don’t you believe it? Just turn off your phone and you can see you can use WhatsApp Web normally! So you can start using WhatsApp Web without an Internet connection on your phone.

When you join the beta program for multi-device, and you connect to WhatsApp Web/Desktop for the first time, you will start using a beta version of the web/desktop client! Yes, you need to join the beta program manually, but you can always opt back out. If you want to discover if you’re one of the lucky users, just open WhatsApp Web/Desktop Settings from your iPhone or Android device (WhatsApp might rename it to Linked devices in the meantime, but this does not mean you have received the feature) and, if the feature is enabled for your WhatsApp account, you can see a new row called “Multi-device beta”. Mark Zuckerberg and Will Cathcart confirmed in our interview that multi-device was coming within 2 months, and we are finally happy to announce that WhatsApp is starting to roll out multi-device for specific beta testers on WhatsApp beta for Android and iOS today! You cannot message or call people that have an outdated WhatsApp version installed, from WhatsApp Web/Desktop or Portal.Voice and video calls work across linked devices.It’s possible to link up to 4 devices to your WhatsApp account.This first version of multi-device does not support another additional phone, but it’s possible they will provide the support in the future, seen that WhatsApp was working on a log out option on linked mobile devices.

WhatsApp Web, WhatsApp Desktop and Portal can work without an active Internet connection on your mobile phone.

Multi-device is surely the most discussed topic here at WABetaInfo, and we were the first to announce the feature, providing several details:
