What is Steam?
Steam is a leading digital game distribution platform developed by Valve Corporation, serving over 132 million monthly active users as of 2025. You can purchase, download, and play your favorite games from an extensive library of over 50,000 titles. Beyond gaming, Steam offers robust community features including forums, chat functionality, review pages, and user-generated content sharing, allowing gamers to connect with like-minded individuals and make informed decisions when purchasing games.
Steam is accessible across multiple platforms including PC, Mac, Linux, and mobile devices through the Steam Mobile app, offering a seamless gaming experience with cloud saves, achievement tracking, and remote play capabilities. The platform also supports Steam Workshop for mods, Steam Market for trading items, and Steam Deck compatibility for portable gaming.
Why Does Steam Require Phone Verification?
Steam implemented mandatory phone number verification in 2025 to enhance account security and combat fraud. This two-factor authentication system helps protect your valuable game library, in-game purchases, and trading activities. However, many users prefer not to share their personal phone numbers due to privacy concerns or simply don’t want gaming-related notifications on their primary device.

Setting Up Mobile Authentication for Steam with MobileSMS.io
Follow these detailed steps to set up mobile authentication for your Steam account using a temporary phone number from MobileSMS.io:
Step-by-Step Process:
- Choose Your Number Type: Visit MobileSMS.io and select a suitable temporary phone number product. For Steam verification, we recommend either a one-time-use number for basic verification or a 30-day rental from our long-term rental collection if you need ongoing access for Steam Guard codes.
- Select Your Country: Choose a temporary phone number from MobileSMS.io that matches the country you want your Steam account registered in. US numbers are most popular and work seamlessly with Steam’s verification system.
- Access Steam Mobile: Download the official Steam Mobile app on your smartphone and sign in with your Steam credentials. Navigate to the main menu and select ‘Steam Guard’ from the dropdown list.
- Add Authenticator: Click on ‘Add Authenticator’ and carefully enter the temporary phone number provided by MobileSMS.io. Ensure you include the correct country code format.
- Verify with SMS Code: Steam will send an SMS containing a 5-digit verification code to your MobileSMS.io number. Check your MobileSMS.io dashboard or SMS inbox to retrieve this code immediately.
- Complete Setup: Enter the verification code under the ‘Step 2’ section in the Steam app. Steam will generate a Recovery Code – write this down and store it securely as you’ll need it for future account recovery.
- Activate Steam Guard: Your Steam authenticator will now be active, generating time-based codes every 30 seconds. Use these codes along with your password when logging into Steam from new devices.
Pro Tips for Success:
- Act Quickly: SMS codes typically expire within 15 minutes, so complete the process promptly
- Double-Check Numbers: Verify the phone number is entered correctly to avoid failed verification attempts

Frequently Asked Questions (FAQ)
Can my Steam account get suspended for using a temporary phone number?
While we cannot guarantee that your account won’t be suspended, using a reliable service like MobileSMS.io significantly reduces the risk as our numbers are real SIM card numbers, not VoIP. Always follow Steam’s terms of service to ensure compliance. Our non-VoIP numbers have been successfully used by thousands of Steam users since 2020.
Can I update or remove the phone number on my Steam account?
Yes, you can update or remove the phone number on your Steam account through your Account Details page. However, removing phone verification will disable Steam Guard mobile authentication, which may limit certain features like trading and market access.
How long do I need access to the temporary number?
For basic Steam verification, a one-time use number is sufficient. However, if you log in from multiple devices frequently, consider a 30-day rental to ensure you can access Steam Guard codes when needed.
Will Steam accept non-US phone numbers from MobileSMS.io?
Yes, Steam accepts phone numbers from most countries. MobileSMS.io offers numbers from multiple regions, though US numbers tend to have the highest success rate for Steam verification in 2025.
What happens if I lose access to my temporary number?
If you lose access to your temporary number, you can still recover your Steam account using your Recovery Code or through Steam Support. This is why it’s crucial to save your Recovery Code during the initial setup process.
Why Privacy Matters for Gaming Accounts
In 2025, digital privacy has become increasingly important for online gaming. Using your personal phone number for gaming accounts can expose you to:
- Unwanted Marketing: Gaming companies often share data with partners
- Security Risks: Data breaches can expose personal information
- Spam and Robocalls: Gaming-related promotional calls and texts
- Identity Linking: Connecting your gaming habits to your real identity
MobileSMS.io helps maintain this separation while still providing the security benefits of two-factor authentication.
