Solution 1Recommended

Set Up Microsoft Authenticator to Avoid Roaming Charges

Use the Microsoft Authenticator app over a Wi-Fi connection to receive sign-in prompts without relying on cellular networks.

Switching your verification method from SMS or phone calls to an Authenticator app ensures you will not be charged by your mobile carrier when traveling. The app can generate codes offline or receive push notifications via Wi-Fi.

Access your Security Info

Navigate to the My Sign-Ins security info page at https://mysignins.microsoft.com/security-info and sign in with your work, school, or personal account.

Manage your verification methods

Under the 'Security info' section, click on 'Add method' to configure a new way to verify your identity.

Select Authenticator App

Choose 'Authenticator app' from the dropdown list and follow the on-screen instructions to link the Microsoft Authenticator app to your account.

Wi-Fi Authentication: Once configured, you only need an internet connection (such as hotel Wi-Fi) to approve sign-in requests, bypassing cellular roaming entirely.

Solution 2

Contact Your Organization's IT Administrator

Frequently Asked Questions

Do I need an active cellular plan to use Microsoft Authenticator abroad?

No. The Microsoft Authenticator app can receive push notifications over a Wi-Fi connection or generate time-based verification codes completely offline, bypassing the need for an active cellular plan or roaming.

Will I be charged for SMS verification codes internationally?

Yes, depending on your mobile operator's roaming policy, receiving international text messages or phone calls for account verification may incur additional carrier charges.

Why is the option to add an authenticator app disabled on my account?

If you are using a work or school account, your organization's IT department likely has strict security policies in place that prevent users from manually altering their MFA settings. You will need to contact your Microsoft 365 administrator to update your verification methods.
