Question 1

Why is Microsoft asking me to verify my phone number?

Accepted Answer

Microsoft asks for a phone code during signup and whenever it needs to confirm your identity. Common triggers include a sign-in from a new device or location, a password reset, and a change to your security info or other sensitive settings. The code goes to the phone number saved as security info on your Microsoft account.

Question 2

Why did Microsoft send me a verification code I didn't request?

Accepted Answer

An unrequested code means someone entered your email address or phone number on a Microsoft sign-in or reset page. It may have been a typo, or someone may be trying to get into your account. Do not share the code with anyone. Check the recent activity page in your Microsoft account for unfamiliar sign-in attempts. If you see one, change your password.

Question 3

Does Microsoft ever contact you by phone?

Accepted Answer

Microsoft states that it does not make unsolicited phone calls or send unsolicited messages to ask for personal information or offer tech support. A call or pop-up claiming to be a Microsoft security alert that asks for a code, a payment or remote access is a scam. Real verification codes normally arrive after you start a sign-in or change on your own account.

Question 4

Which VoidMob number should I use for a Microsoft account?

Accepted Answer

Use a dedicated monthly line if the number will stay on the account as security info. You keep the number, so later sign-in and recovery codes still reach you. A one-time OTP from $0.15 covers signup only, since the number is active for 15 minutes. Microsoft can hold a later change to security info as pending for 30 days, so add a recovery method you control before relying on it.

Question 5

What happens if the Microsoft code never arrives?

Accepted Answer

A VoidMob one-time OTP stays active for 15 minutes. If no code arrives in that window, the rental cancels automatically and refunds in full to your wallet. Once a code has been delivered, the rental cannot be refunded. You can request a resend on the same number for free while the window is still open.

Question 6

Does one number cover Outlook, Hotmail and Xbox?

Accepted Answer

Yes. Outlook.com, Hotmail and Xbox all sign in with the same Microsoft account, so one verified number is the security info for all three. Losing access to that number affects every service tied to the account. That is why a number you keep is safer than a short-lived one.

Question 7

Are the Microsoft numbers non-VoIP, and do I need ID?

Accepted Answer

Yes, every number is a real carrier line rather than VoIP, and no ID is needed: you sign up with a crypto wallet or an email and pay from a crypto-funded balance.

Question 8

What if the Microsoft code never arrives?

Accepted Answer

A one-time US number stays active for 15 minutes, and if no code arrives in that window the order cancels itself and refunds in full to your balance.
