Solution 1Recommended

Verify Billing History and Contact Microsoft Support

Check if the charges are linked to your known account and initiate a support chat with Microsoft to investigate the unrecognized transactions.

Often, fraudulent charges occur when your payment method or phone number is linked to a different, compromised account. Microsoft Support can help track down the source of the charges using the transaction details from your bill.

Review your Microsoft billing history

Go to account.microsoft.com/billing/orders and sign in with your Microsoft account. Check if any of the transactions on your phone bill match the orders listed here.

Navigate to Microsoft Support

If the charges do not appear in your account, visit support.office.com/home/chat to speak with an agent.

Search for the issue

Type 'unknown charge' or 'fraudulent charge' into the search box and select the 'Get Help' button.

Access live support

Click 'Contact support' at the bottom of the page. Select 'Microsoft 365 and Office' as the product and 'Manage my subscription' as the category.

Start the chat

Select 'Chat with support agent' and then 'Start Chat' to connect with a representative who can investigate the carrier charges.

Verify Billing History and Contact Microsoft Support

Prepare Transaction Details: Have the exact dates, amounts, and any merchant reference numbers from your phone bill ready to share with the Microsoft support agent.

Solution 2

Dispute Charges Through Your Mobile Carrier and Secure Accounts

Prevent further unauthorized billing by contacting your mobile service provider to block third-party charges and updating your security settings.

Frequently Asked Questions

Why am I getting Microsoft charges on my mobile phone bill?

Microsoft allows certain digital purchases, such as Xbox games or Microsoft 365 subscriptions, to be billed directly to a mobile carrier (known as carrier billing). If you did not authorize these, someone may have fraudulently linked your phone number to their account.

How do I stop Microsoft from continuously charging my phone bill?

If the charges are linked to your account, you can stop them by removing the mobile billing payment method at account.microsoft.com. If the charges are unauthorized and not in your account, you must contact your mobile carrier directly to block Microsoft as a merchant.

Can I get a refund for unauthorized Microsoft purchases on my phone bill?

Yes. If the purchases were fraudulent, you can request a refund by contacting Microsoft Support with the transaction details. If Microsoft cannot locate or refund the charges, your mobile carrier or bank can often reverse the unauthorized transactions through a fraud dispute.

Where can I see my complete Microsoft billing history?

You can view all past purchases, active subscriptions, and the billing history linked to your personal Microsoft account by logging in to account.microsoft.com/billing/orders.
