Thank you for reaching out to us.

Due to increased levels of fraud occurring in specific countries, the MFA service has placed country level blocks for voice/sms traffic, however you can work with Microsoft Support team to whitelist those countries (where your users experiencing issue while receiving text during authentication) for your tenant in specific.

Also wanted to share some known issues with SMS-based authentication

Let me know if you have any questions.

Thank you for your answer. How about the second question, can we use sms-based login to our Intune devices, windows log-on?

Also, do we need oma-uri if we deploy this in our company?

Appreciate your help.

can we use sms-based login to our Intune devices, windows log-on? - No, this is not possible, you cannot use sms option to logon interactively on windows devices.

If you are looking for option apart from password for security purpose, you can leverage Windows hello for business,

Regarding OMA-URI (this is aligned towards Intune configuration) - Windows client custom profiles use Open Mobile Alliance Uniform Resource Identifier (OMA-URI) settings to configure different features. These settings are typically used by mobile device manufacturers to control features on the device.

Windows client makes many Configuration Service Provider (CSP) settings available, such as Policy Configuration Service Provider (Policy CSP).

For more details on OMA-URI, I would suggest to open a new QnA post use tag mem-Intune-device-configuration ( https://hmaslowski.com/mem-%2F-intune/f/configure-local-admins-via-custom-oma-uri-policy-in-memintune) to get expertise inputs from Intune team.

Let me know if you have any further questions.
