  • USA
  • France
  • Sweden

This is expanding into Austria, Belgium, Denmark, Germany, Ireland, Italy, Mexico, Luxembourg, Spain,  and Poland by the end of 2024.

Countries not in our Global Pass will incur roaming charges.

You will need to activate your eSIM in one of our home countries first.

What features of Teams Calling aren't available?

  • Voicemail
  • Call forwarding
  • Teams call group
  • Call queue agent answering
  • Hold
  • Transfer
  • Compliance call recording *

What if I have Callroute Go and the Teams Mobile App installed?

If you have Callroute Go eSIM enabled and the Teams app on the same phone, then the phone will ring twice.
