Curve is an innovative financial app that allows you to connect all your debit and credit cards into a single smart card and app. To set up this powerful financial tool, you must complete a secure verification with a phone number. For an app that sits at the very center of your financial life, a dedicated virtual phone number is an advanced security measure to protect your entire wallet.
Your Curve account is a "single point of control" for your other cards, making its security absolutely critical. A private virtual number, used exclusively for Curve, acts as a high-security key. Since this number is not public and isn't tied to your social media, it makes it incredibly difficult for fraudsters to target you with SIM swap attacks to try and gain control over your entire payment ecosystem.
A virtual number allows you to completely isolate your Curve financial hub from all your other online activities. A potential data breach at a shopping website or social media app you use will have no impact on your Curve account's security, because they are not linked by the same phone number. This compartmentalization is essential for protecting your consolidated financial life.
Using a virtual number allows you to receive sensitive verification codes and transaction alerts with an added layer of privacy. It ensures that your most critical financial communications are sent to a dedicated, secure line, separate from your daily social messages. This provides a cleaner, more organized, and ultimately more secure way to manage your money.
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 "Curve". 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 Curve verification screen to complete registration.
Both options let you receive an SMS code on a Curve number. The difference is in reliability and privacy.
Yes, our numbers are specifically designed for Curve registration. Curve 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 Curve account.
First, double-check that you've copied the SMS code precisely as it appeared in your SMSFAST account and entered it correctly into Curve. 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 Curve. 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 Curve 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 Curve significantly enhances your privacy and security. This allows you to avoid exposing your personal number.
