Can I use multiple sim cards in my phone that runs the Phone.com Mobile Office?
Yes. Though you must log into the Phone.com mobile app after switching sim cards (you may need to log out first in the app). This will automatically authenticate the new sim card’s mobile number. At that point you are ready to make calls. I can’t make Mobile Office calls using the Andriod App.If you are running into problems making Mobile Office calls using the Phone.com Android app, be sure to go into the settings for the app and enable the option for “callback mode”.
