TIER Mobility is a leading European micro-mobility provider, offering shared e-scooters, e-bikes, and e-mopeds in cities across the continent. To start a ride, you must use the TIER app, which requires registration and verification with a phone number. A temporary phone number is the ideal companion for using this service while protecting your privacy and personal data.
A micro-mobility app like TIER tracks your every trip, creating a detailed history of your movements, routines, and frequent destinations. A virtual number helps to de-link this sensitive location data from your core personal identity. It allows you to enjoy the convenience of TIER vehicles without connecting your travel patterns directly to your primary phone number.
Once an app understands your travel habits, that information can be used for targeted marketing. A temporary number shields you from receiving unsolicited promotional messages based on the places you visit. It keeps your personal phone free from commercial offers, allowing you to ride without being tracked for marketing purposes.
Using a virtual number for registration adds a layer of security to your account. In the event of a data breach, your real phone number—a key piece of your digital identity—remains unexposed. It’s a simple, proactive step to take for a safer and more private journey every time you decide to use a TIER vehicle.
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 "TIER". 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 TIER verification screen to complete registration.
Both options let you receive an SMS code on a TIER number. The difference is in reliability and privacy.
Yes, our numbers are specifically designed for TIER registration. TIER 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 TIER account.
First, double-check that you've copied the SMS code precisely as it appeared in your SMSFAST account and entered it correctly into TIER. 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 TIER. 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 TIER 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 TIER significantly enhances your privacy and security. This allows you to avoid exposing your personal number.
