Fix Microsoft Verification SMS Arriving Only After Multiple Attempts
Question details
The user is experiencing a delay with Microsoft verification SMS codes, receiving them only after requesting two or three times.
- Product
- Microsoft Account / Microsoft 365
- Device & OS
- not provided
- Scenario
- Authenticating a Microsoft account that requires Multi-Factor Authentication (MFA) via SMS.
- Observed behavior
- SMS verification codes are significantly delayed or fail to arrive on the first request, requiring multiple attempts before successful delivery, despite other SMS services working normally.
Ensure your mobile device has a stable cellular connection and verify that you have not accidentally blocked shortcode numbers from Microsoft in your messaging settings.
Contact Microsoft Support for Account Assistance
Since this involves backend SMS routing and account security, contacting Microsoft Support is the most effective way to resolve persistent SMS delays across multiple accounts.
If you are consistently experiencing delays with your SMS verification codes across multiple Microsoft accounts, the issue is likely tied to Microsoft's SMS gateway or how it interacts with your specific carrier. Resolving this often requires direct intervention from Microsoft support.
Go to the official Microsoft 365 admin help and support page at https://learn.microsoft.com/en-us/microsoft-365/admin/get-help-support.
Gather the affected Microsoft account details and note the approximate dates and times you experienced the SMS delivery failures.
Follow the prompts to submit your issue. For security reasons, do not share your phone number, account password, or verification codes in public forums or community boards.

Frequently Asked Questions
Why are my Microsoft verification codes taking so long to arrive?
Delays are often caused by temporary carrier network congestion, SMS gateway routing issues between Microsoft and your mobile provider, or backend delays on Microsoft's servers.
Can I log into my Microsoft account without SMS verification?
Yes, if you have previously set up alternative authentication methods, you can choose to receive your security codes via an alternate email address or use an Authenticator app instead of waiting for a text message.
Is it safe to request multiple SMS verification codes in a row?
While it is safe to request another code if one fails to arrive, requesting too many codes in a short period might temporarily lock your account or trigger fraud prevention mechanisms. It is best to wait a few minutes before requesting another code.
