Common Reasons for SMS Verification Lockouts (And How to Fix Them)
Mistakes in Entering Phone Numbers
Errors in typing phone numbers account for 23% of account lockouts (SecureBlink, 2024). These mistakes often happen when users enter the wrong country codes, area codes, or digits. For instance, entering "+1" instead of "+44" for a UK number sends the verification code to the wrong recipient.
Here are some common errors:
| Error Type | Example |
|---|---|
| Missing Country Code | 555-0123 instead of +1-555-0123 |
| Incorrect Format | (555)0123 instead of 555-0123 |
| Transposed Digits | 585-0123 instead of 555-0123 |
SMS Delivery Issues
Sometimes, carrier systems flag verification messages as spam, especially during periods of high traffic. Network congestion can also delay SMS delivery, causing codes to expire before they can be used (usually within 5-10 minutes). Additionally, international SMS restrictions may block messages entirely, making account verification across borders more difficult.
Rejection of VoIP Numbers by Platforms
Many platforms, including Google, WhatsApp, and Telegram, block VoIP numbers due to security risks. These numbers are:
- Easy to obtain and often recycled without proper identity checks
- Commonly used in fraudulent activities
- Hard to trace back to real users
For reliable verification, stick to SIM-based numbers from services like MobileSMS.io. These numbers meet platform requirements and protect your personal number, offering a dependable and private solution for account verification.
Steps to Prevent Account Lockouts
Use Trusted and Compatible Phone Numbers
As major platforms like Snapchat enhance their verification systems to combat bot activity, it’s crucial to use phone numbers that meet their requirements. Many platforms now reject VoIP numbers, so choosing the right type is essential.
Here’s a quick breakdown of phone number options:
| Number Type | Platform Acceptance | Privacy Level | Recommended Use Case |
|---|---|---|---|
| Personal SIM | High | Low | Verifying a single account |
| Non-VoIP Rental | High | High | Business use or multiple accounts |
| VoIP Numbers | Low | Medium | Not ideal for verification |
Set Up Backup Verification Options
Adding backup verification methods can help you avoid being locked out. As noted by Intuit:
"Multi-factor authentication is a security enhancement layered on top of the usual password requirement. You’ll need to add your preferred mobile phone number or email address to your Intuit Account for this feature."
Consider enabling these backup options:
- Authenticator apps like Google Authenticator or Microsoft Authenticator
- Recovery email addresses for added flexibility
- Backup codes stored securely offline
- Security questions with answers only you would know
Keep Contact Information Updated
Regularly updating your contact details reduces the risk of lockouts. Here’s how to stay on top of it:
1. Test Before Switching
Before replacing an old number, validate the new one with a test account. Keep the old number active temporarily to catch any delayed codes.
2. Maintain a Record
Track which accounts are linked to specific numbers in a secure file or system.
3. Schedule Updates
Review and update your contact information every few months to ensure everything stays current.
If you’re managing multiple accounts, consider using a dedicated SMS verification service. For instance, MobileSMS.io offers a centralized dashboard to organize and update your verification numbers efficiently.

Using Privacy-Focused Verification Tools
Privacy-focused tools can be a smart way to back up your verification methods. They provide alternatives to using personal numbers, helping to avoid lockouts. Disposable numbers, in particular, tackle three main security concerns: stopping SIM-swap fraud, cutting down on spam, and making account management easier.
Why Use Real SIM-Based Disposable Numbers from MobileSMS.io?
Not all disposable numbers work for verification—many VoIP services get rejected. MobileSMS.io provides real SIM-card-based numbers, ensuring higher success rates across platforms like Google, WhatsApp, and Telegram.
- Defense against SIM-swapping attacks: Keeps your accounts safe from this common threat.
- Less spam: Using a disposable number reduces the chances of spam messages reaching your personal phone.
- Easier account management: They simplify how you handle multiple accounts.
Traditional vs. Non-VoIP SMS Solutions
When choosing a number for verification, it’s important to weigh the differences between personal and non-VoIP numbers. Here’s a quick comparison:
| Feature | Personal Numbers | Non-VoIP Numbers |
|---|---|---|
| Platform Acceptance | Can vary | Widely accepted on major platforms |
| Privacy Protection | Limited – your number is exposed | Strong – unique number for each service |
| Lockout Risk | Higher due to carrier issues | Lower with dedicated verification numbers |
| Geographic Flexibility | Usually local use only | Access to numbers from many countries |
| Account Management | Requires manual tracking | Often includes a centralized dashboard |
This method ensures you meet platform requirements while improving security and convenience.
Solving Common SMS Verification Problems
If SMS verification isn’t working, here are some practical steps to address the issue and regain access to your account. These tips focus on resolving technical problems that might be blocking your verification.
Check for Blocked Numbers or Spam Filters
Blocked numbers or spam filters can stop verification messages from reaching you. Here’s how to fix it:
On Your Device:
- Unblock any numbers in your phone’s settings.
- Look for messages in your SMS spam folder.
- Turn off any message filtering features.
With Your Carrier: Ask them to:
- Remove blocks on short codes.
- Enable automated message delivery.
- Confirm that SMS permissions are correctly set up.
Ensure Network Connectivity
A weak or unstable connection can also cause problems. Try these steps to improve your signal:
- Toggle airplane mode on and off to reset your connection.
- Test whether 4G or 5G provides a better signal.
- Make sure your signal strength is at least 2 bars.
- Update your carrier settings if needed.
Get Help from Support
If troubleshooting on your own doesn’t work, it’s time to seek help. Dr. Lorrie Faith Cranor from Carnegie Mellon University emphasizes:
"SMS verification remains one of the most widely used two-factor authentication methods due to its simplicity and widespread adoption. However, it’s crucial for businesses to have fallback options and troubleshooting processes in place to ensure a smooth user experience."
Reach out to your mobile carrier’s support team or the platform’s customer service for assistance. If all else fails, consider using alternative verification services. For example, MobileSMS.io offers SIM-based numbers with a 7-day money-back guarantee, giving you a dependable backup when traditional methods don’t work.
Conclusion: Tips to Avoid Account Lockouts
Keep your accounts secure and accessible by focusing on these key practices:
- Use non-VoIP SIM-based numbers from providers like MobileSMS.io. These numbers work with platforms like Google, Telegram, and WhatsApp, which often block virtual numbers. Plus, they’re available in over 100 countries for wide compatibility.
- Opt for disposable numbers to bypass restrictions on personal numbers and protect your privacy. This helps reduce risks like data breaches and spam while ensuring uninterrupted access to your accounts.
- Set up backup methods, such as authenticator apps, to have an alternative if SMS codes fail. Also, make sure to update your registered numbers regularly to avoid issues with expired or inaccessible codes.
