Hi @Abu Hurayra,
Welcome to Microsoft Q&A Forum, thank you for posting your query here!
If you have problems with the phone validation in the Azure Account creation process, please take a look here: Identity verification by phone
Here is some additional information:
You can use any phone number for verification as long as it meets the requirements. The phone number that you enter for verification isn't stored as a contact number for the account.
- A Voice-over-IP (VoiP) phone number can't be used for the phone verification process
- Check that your phone can receive calls or SMS messages from a United States-based telephone number.
- Double-check the phone number that you enter, including the country code that you select in the drop-down menu.
- If your phone doesn't receive text messages (SMS), try the Call me option.
Source: No verification text message or phone call
Make sure to select the right country code in the drop-down and enter the phone number without the country code.
One option might be to call Microsoft's Global Support: Global Customer Service phone numbers
