Yes. With Google Workspace, you're able to read and send emails on the go as well as attend meetings remotely. Google Workspace apps can be downloaded for Android and iOS devices so you can access them at all times no matter where you are. It's especially simple to set up for Android: you only need to add your Google Workspace account once to your mobile device in order for your email, contacts, and calendar events to be available on that device. For iOS, you additionally have to set up Google Sync before you can start using mail, contacts and calendar. Choose which products you want to synchronise with your device and simply repeat the same steps for every account you want to add.
It's also possible to use Google Workspace offline as long as you set it up while you're online: as an administrator, you need to have enabled offline access via the admin console dashboard.
