How to Sign Up and Use Signal Without Using Your Own Phone Number

Signal is a popular messaging app that is known for its security and privacy features. However, in order to sign up for an account, you are required to provide a mobile phone number for SMS verification purposes. (Updated August 2025)

This can be a problem for those who want to create a second account, protect their privacy, or don’t want to give away their personal phone number. Whether you’re concerned about data privacy, need multiple accounts for different purposes, or simply want to keep your personal number separate from messaging apps, there are legitimate reasons to seek alternatives.

Fortunately, at MobileSMS.io, we provide an alternative way for you to verify your Signal account by using our temporary phone numbers. Our service uses real sim card numbers that are NOT prepaid numbers, which means that you can create a Signal account without using your own phone number, giving you the freedom to use the app without worrying about giving away your personal information.

Why Use a Temporary Number for Signal in 2025?

In 2025, privacy concerns have reached an all-time high. Here are the top reasons people choose temporary numbers for Signal registration:

• Enhanced Privacy Protection: Keep your personal number completely separate from messaging platforms
• Multiple Account Management: Create separate Signal accounts for work, personal use, or different projects
• Avoid Spam and Unwanted Contacts: Prevent your main number from being added to unwanted group chats or contact lists
• Testing and Development: Ideal for developers or businesses testing Signal integrations
• International Users: Perfect for those who frequently travel or need numbers from specific countries
• Security Research: Researchers and security professionals often need isolated accounts for testing

Step-by-Step Guide to Creating Your Signal Account

Step 1: Sign up for an account at MobileSMS.io. Our service offers a variety of temporary phone numbers to choose from, including one-time use, 7 day rental, 30 day rental, and long term rental numbers. For Signal, we recommend our 30-day “All Services” plan, which provides reliable access and works with virtually all verification services.

Step 2: Select a temporary phone number from MobileSMS.io that is from the country that you want your Signal account to be registered in. In this example, we use United States and the number provided is 916-705-9429. Pro tip: Choose a number from your actual location or preferred region to avoid any potential geo-blocking issues.

Step 3: Download the Signal app from the App Store or Google Play and open it. Make sure you’re downloading the official Signal app (Signal Foundation) to ensure security and authenticity.

Step 4: Tap on “Create account” and enter your temporary phone number provided by MobileSMS.io. Enter the full number including country code (for US numbers, include +1 before the area code).

Step 5: Wait for Signal to send the verification code, then check your MobileSMS.io dashboard for the incoming SMS. Verification codes typically arrive within 30-60 seconds. If you don’t receive the code immediately, wait a few minutes before requesting a new one, as Signal has rate limiting in place.

Step 6: Enter the verification code sent to the temporary phone number. Copy the 6-digit code exactly as received in your MobileSMS.io account.

Step 7: Complete your Signal profile setup by adding a profile name and photo if desired. You can skip these steps and add them later if you prefer.

Step 8: Set up your Signal PIN for account recovery and security. This is crucial for maintaining access to your account even if you lose access to the temporary number later.

Step 9: Enjoy your new Signal account without the need to provide your personal phone number!

Important Considerations and Best Practices

Account Security Tips

• Set Up Signal PIN: This is your most important security step. Without it, you could lose access to your account permanently
• Enable Registration Lock: This prevents others from registering your Signal account on a new device without your PIN
• Backup Your Account: Create a backup of your Signal messages and contacts regularly
• Document Your Setup: Keep a secure record of which temporary number you used and when

Potential Limitations to Be Aware Of

• Contact Discovery: People who have the temporary number in their contacts might see your Signal account
• Account Recovery: If you lose access and forget your PIN, recovery can be challenging without access to the original number
• Re-verification: Signal may occasionally require re-verification, especially if you’re using the account from different devices or locations

Troubleshooting Common Issues

Verification Code Not Received

If you don’t receive the verification code:

1. Wait 2-3 minutes before trying again (Signal has rate limits)
2. Check that you entered the complete phone number with country code
3. Try requesting the code via voice call instead of SMS
4. Contact MobileSMS.io support if the number appears to be blocked

Number Already in Use

If Signal says the number is already registered:

1. The number may have been used previously – try selecting a different number
2. Wait 24-48 hours and try again, as the previous registration may expire
3. Choose a longer-term rental to avoid this issue
