Temporary Phone Number for OpenSesame Verification
A temporary phone number for OpenSesame verification gives you a one-time-use number that receives your SMS code and then expires — keeping your personal phone number completely private. This is the safest approach when signing up for new services, because you never expose your real contact information. Unlike a temp phone number from free websites where hundreds of strangers can see the same inbox, SMSVerifier provides a private temporary number that only you have access to.
Our temporary phone numbers are sourced from real mobile carriers across 9+ countries, which means they pass OpenSesame's verification checks just like a regular SIM card would. After you receive your OpenSesame code, the temp phone number automatically expires. If you need ongoing access for password resets or two-factor authentication on OpenSesame, we also offer rental numbers that stay active from 4 hours up to 4 weeks.
Virtual Phone Number for OpenSesame — Non-VoIP Real Carrier SIM
Not all virtual phone numbers are created equal. Many providers offer cheap VoIP-based numbers that OpenSesame and other major platforms actively detect and block. SMSVerifier is different — we provide non-VoIP virtual numbers backed by real mobile carrier SIMs from operators like T-Mobile, Vodafone, Airtel, and hundreds more worldwide. These are the same type of numbers that come with physical SIM cards, which means OpenSesame treats them as legitimate phone numbers with the highest acceptance rates.
When you need a virtual number for OpenSesame verification, choosing a non-VoIP number makes all the difference. Our real SIM numbers consistently achieve 90%+ success rates across all verification types, including difficult platforms that reject most virtual numbers. With 3,817+ numbers available across 9 countries, you'll always find a working virtual phone number for OpenSesame at the right price.
Available Countries for OpenSesame Verification

Best Countries for OpenSesame Verification
Based on price, availability, and success rates, these are the top picks for OpenSesame:
Receive OpenSesame Verification Text Online Without an App
Need to receive a OpenSesame verification text online without installing any app or buying a SIM card? SMSVerifier works entirely from your web browser — desktop, tablet, or mobile. Simply log in, pick your country, purchase a number, and the verification text appears directly on your screen. There is nothing to download, no phone calls to answer, and no physical hardware required. This makes it the fastest way to text receive online for any verification purpose.
This browser-based approach is especially useful when you're setting up OpenSesame on a computer, working from a device without a SIM slot, or managing multiple accounts efficiently. Unlike free text receive online services that display everyone's messages publicly (making your verification code visible to others and often already used), our platform keeps your OpenSesame SMS completely private and visible only to you.
Free Phone Number vs Paid OpenSesame Verification — What Actually Works?
You might wonder if a free phone number is enough to verify your OpenSesame account. Free SMS services are tempting, but they come with serious drawbacks: the numbers are shared publicly, meaning anyone can see your verification codes before you do. Most free phone numbers are already flagged and blocked by OpenSesame because thousands of people have used them. The result? Wasted time, failed verifications, and frustration.
A fake phone number from random generators won't work either — these are mathematically valid numbers that can't actually receive SMS messages. What you actually need for OpenSesame is a real, private phone number that receives genuine SMS texts. That's exactly what SMSVerifier provides. Starting from just $0.42, you get a dedicated number from a real mobile carrier that OpenSesame recognizes and trusts. It's a small investment that saves hours of frustration compared to cycling through blocked free phone numbers or fake numbers that never work.
OpenSesame OTP Verification — Receive One-Time Password Instantly
OTP verification (One-Time Password) is the security method OpenSesame uses to confirm your identity. When you register, log in from a new device, or perform sensitive actions, OpenSesame sends a unique OTP code via SMS to your phone number. This code is valid for a limited time — typically 2 to 10 minutes — and can only be used once. SMSVerifier lets you receive OTP online from OpenSesame without needing a physical SIM card or phone line.
Our platform is optimized for fast OTP delivery — the average time between OpenSesame sending the code and it appearing on your dashboard is under 30 seconds. This speed is critical because OTP codes expire quickly. Whether you need a one-time verification OTP or regular two-factor authentication codes, our numbers handle all types of OpenSesame OTP verification reliably across 9+ countries.
Disposable and Burner Phone Number for OpenSesame Account Setup
A disposable phone number is perfect when you need to verify OpenSesame without creating a permanent link to your identity. Think of it as a burner phone number — it exists long enough to receive your verification code, then disappears. This approach is popular among privacy-conscious users, digital marketers managing multiple accounts, developers testing their applications, and anyone who wants to keep their personal phone number separate from online services.
Unlike physical burner phones that cost $20-50 each, SMSVerifier's disposable numbers start at just $0.42. You get the same privacy benefit as a burner number at a fraction of the cost. Need a second phone number for OpenSesame without carrying a second device? Our web-based platform gives you an anonymous phone number from any of 9+ countries, accessible from any browser. No contracts, no hardware, no trace back to your primary number.
