Big C is a major hypermarket and retail chain prominent in Thailand and other Southeast Asian countries. Its loyalty programs and online shopping platforms require phone verification to create an account, collect points, and access member-only deals. Using a temporary phone number is a smart way to get the best prices while protecting your personal data.
When you join a major supermarket's loyalty program, you are creating a detailed profile of your household's purchasing habits. A virtual phone number allows you to register for Big C's program without providing your primary contact number. This minimizes your digital footprint and protects your personal information from being used for extensive marketing profiling or being exposed in a potential data breach.
Loyalty apps are a direct channel for retailers to send promotional texts about weekly specials, flash sales, and partner offers. A disposable phone number is perfect for receiving the initial SMS verification. It lets you create your account and use your loyalty card at the checkout without your personal phone being constantly flooded with marketing alerts.
Using a virtual number adds a layer of security to your retail profile. It ensures your main phone number, which may be linked to sensitive financial accounts, is not associated with your shopping data. This allows you to enjoy the discounts and wide selection at Big C with greater peace of mind, knowing you’ve taken a proactive step to keep your data secure.
Either create a new account by clicking "Registration" or log in if you already have one.
In the top right corner, click "+" and choose a convenient top-up method. Add the amount you need.
In the left menu, under "Select service," click "BigC". Then, choose your region from the list.
Click "Buy" and wait a few seconds for your temporary number to be purchased and activated.
Copy the phone number from the "Number" field to activate the service.
Wait for the one-time password (OTP) to appear in the "Code from SMS" field, then enter it in the BigC verification screen to complete registration.
Both options let you receive an SMS code on a BigC number. The difference is in reliability and privacy.
Yes, our numbers are specifically designed for BigC registration. BigC requires a phone number for account creation, and our virtual numbers provide a reliable way to receive the SMS verification code.
Yes, you can. SMSFAST allows you to rent multiple virtual numbers, meaning you can use a unique number for each BigC account.
First, double-check that you've copied the SMS code precisely as it appeared in your SMSFAST account and entered it correctly into BigC. Also, ensure the number you used is still active and within its valid time frame.
If the issue persists, the number might have been flagged by BigC. In such cases, we recommend simply renting a new temporary phone number and repeating the registration process.
There may be a slight delay in network delivery at times. Please give it a minute or two.
If the code still doesn't arrive after a resend attempt, the temporary number might be experiencing an issue with that specific service. We recommend canceling the current number (if no SMS has been received, you typically won't be charged) and renting a new disposable number from SMSFAST.
A number is valid for up to 20 minutes for SMS verification purposes. This ensures you have enough time to receive your verification code and complete the registration.
Yes, we provide real, non-VoIP numbers from local SIM cards. You can use to register on a variety of services.
No, you generally cannot reuse the same temporary number for BigC registration. It is designed for one-time SMS verification. If you need to register another account, you'll require a new code from a new virtual number.
Yes, it is safe. Using SMSFAST numbers for services like BigC significantly enhances your privacy and security. This allows you to avoid exposing your personal number.
