Key Points:
- Benefits: SMS verification reduces bot attacks, phishing attempts, and targeted attacks significantly, adding an important layer of protection. However, pairing SMS with temporary numbers or stronger methods like authenticator apps ensures even greater security.
- Risks: Vulnerable to SIM-swapping, phishing, and SS7 protocol flaws.
- Alternatives: Authenticator apps, hardware keys, and temporary numbers offer stronger security.
Quick Tips:
- Use temporary numbers (e.g., MobileSMS.io) to protect your personal phone.
- Enable 2FA with stronger methods like authenticator apps or hardware keys.
- Regularly review and update your account security settings.
- Keep personal info private and avoid sharing your phone number unnecessarily.
While SMS adds a layer of security, combining it with other tools and practices is essential to minimize risks and protect your privacy.

Common Risks of Using SMS for Verification
According to FBI data, losses from SMS-based attacks skyrocketed from $12 million between 2018 and 2020 to $68 million in 2021, highlighting how attackers are becoming more advanced.
Types of SMS-Based Attacks
SIM swapping poses a significant risk, where attackers deceive mobile carriers into transferring a victim’s phone number to a new SIM card. This allows them to intercept verification codes and access sensitive accounts. Using temporary, non-VoIP numbers like those from MobileSMS.io can mitigate this risk by keeping your personal number private and off carriers’ radar. A well-known example occurred in 2019 when Twitter CEO Jack Dorsey’s account was compromised through SIM swapping, allowing attackers to post unauthorized tweets.
But SIM swapping isn’t the only danger. SMS verification is also exposed to phishing attacks and SS7 vulnerabilities. SS7, a protocol used by telecom networks, has weaknesses that allow hackers to intercept unencrypted SMS messages and calls. Phishing schemes targeting SMS are also on the rise. A Forrester study revealed that SMS-based two-factor authentication (2FA) blocks only 76% of attacks, leaving a significant security gap.
"Phones prioritize convenience over security, making SMS 2FA too risky for organizations." – UserLock
"Account takeovers via SMS can go unnoticed, amplifying the risks." – Tracy C. Kitten, Director of Fraud and Security at Javelin Strategy & Research
Weaknesses of SMS as a Security Method
SMS verification comes with several flaws that make it less secure compared to other authentication methods:
| Weakness | Impact | Risk Level |
|---|---|---|
| No Encryption | Messages can be intercepted and read in plain text | High |
| Network Dependence | Vulnerable to SS7 attacks and network outages | High |
| Social Engineering | Susceptible to manipulation via carriers | High |
To better protect accounts, users should consider alternatives like authenticator apps or hardware security keys. These options bypass the vulnerabilities tied to SMS and provide stronger security. Recognizing these risks is crucial before moving on to solutions that can help reduce them.
Using temporary numbers from services like MobileSMS.io can reduce the chances of falling victim to SIM-swapping since your primary number stays private and unexposed to carriers or potential attackers.

Checklist: How to Secure Your Accounts with SMS
Use Temporary Numbers for Verification
Protecting your personal phone number has never been more critical. With MobileSMS.io, you can use temporary, real SIM-based numbers for secure verifications across over 1,200 platforms, reducing the risk of SIM-swapping, phishing, and spam. These non-VoIP numbers work even on platforms that block VoIP, ensuring reliability and privacy. This adds an extra layer of privacy and reduces risks like SIM swapping. Unlike VoIP numbers, MobileSMS.io’s real SIM-based numbers are accepted by platforms that often block virtual phone numbers, ensuring smooth account setup while maintaining your privacy.
Enable Two-Factor Authentication (2FA)
Even though SMS-based 2FA has its weaknesses, it’s still better than having no extra security in place. For platforms requiring SMS verification, consider long-term rental numbers from MobileSMS.io to manage repeated verifications without using your personal phone. That said, stronger options like authenticator apps or hardware keys are recommended. Here’s a quick comparison of common methods:
| Authentication Method | Security Level |
|---|---|
| Hardware Security Keys | Highest |
| Authenticator Apps | High |
| Biometric Verification | High |
| SMS-based 2FA | Moderate |
Adding 2FA is a step in the right direction, but don’t overlook the importance of safeguarding your personal details.
Keep Your Personal Information Private
Be smart about how you share your phone number. Keep track of services that require it for verification, and avoid using it for things like loyalty programs or other non-essential platforms. You can also ask your carrier about extra security features, such as account passcodes or number locking.
Review and Update Security Settings Regularly
To stay ahead of potential SMS vulnerabilities, make these steps part of your routine:
- Use strong, unique PINs for your accounts.
- Regularly check and update the verification methods linked to your accounts.
- Every few months, review your carrier’s security options and enable features that add more protection.

Apps like Signal offer end-to-end encryption and collect minimal user data, making them a reliable choice when SMS verification isn’t required. However, SMS remains an important tool for account verification on many platforms. While secure messaging apps like Signal are ideal for sensitive conversations, SMS remains crucial for account verification on platforms that don’t support alternative methods.
Strengthen Browser and Device Security
A secure SMS verification process starts with tightening your digital defenses. You can improve your security by:
- Switching to privacy-friendly browsers like Brave
- Activating HTTPS-only mode to prevent man-in-the-middle attacks
- Adding trusted ad blockers and privacy-focused browser extensions
These steps not only safeguard SMS verification but also protect your overall online activity.
