We use only real phone numbers - Non-VoIP. That is why you need to wait for the SIM card to start and go online. Real numbers are more secure for receiving SMS as they are tied to physical equipment and are not subject to hacking or replication.
Many account activation and verification services do not support virtual numbers. In addition, the lifespan of a virtual number can be measured in minutes. Services can request reactivation after a few days, and there is a 99% chance that you will no longer have access to the virtual number. With us, you can request reactivation from the same number for a specific service and after some time. And when using a dedicated number, its lifespan can be from 30 to 365 days.
The technology of receiving text messages to virtual numbers is called SMS PVA. In essence, the mobile phone numbers of real users are used through infected Android phones and other devices with SIM cards installed (routers, navigators, etc.) using malware. The owners of infected devices are unaware of the use of their devices, since the malware does this covertly. If desired, third parties always have the ability to gain access to accounts (action history, correspondence, purchases and payment data) by re-requesting access via SMS authentication and password recovery.
No. All functions are available after simple registration, where only an e-mail address is required. The service is privacy-focused: we do not ask for your name, home address or personal phone number. However, SMS-Box cannot guarantee anonymity against valid official legal requests.
After registration, you need to type the service you are interested in in the search bar and select it. The number of available numbers will be indicated next to the service. Available countries are indicated on the right. There must be sufficient funds in the account. After selecting a country, you need to click the Get number button. After waiting for activation for 1-3 minutes, you will receive a phone number. Next, you enter the phone number on the device in the required service and wait for an SMS with a verification code on the website. The number will wait for an SMS for 5 minutes. The history of received SMS is saved in your account.
You have entered an incorrect number or country code, please check all the digits. The wrong service from which the SMS is expected was selected on the website. Or, there is a problem with the requested service and it is temporarily unavailable.
No. All available services and numbers are unique. We also guarantee that no one else will be able to use the service and number you selected.
Yes, we provide private unique access to the number for rent, where all services without restrictions will be available only for you. The new number will be activated only for you and has never been used before. Please use the corresponding function in your personal account after registration - Private numbers.
We provide access to the number from the moment of activation for 30 - 120 days or more. The period may be limited by the operator for reasons beyond our control.
Please select Other service at the end of the list.
To receive such information by e-mail, we recommend that you check the box to receive a newsletter with up-to-date data when registering. You can also check the box to receive such news after registering in your personal account.
We do not provide test numbers and accounts, as we use only real unique numbers.
Please use the password recovery function. If you cannot remember the e-mail specified during registration, it is impossible to restore access to the account.
No. All services are available only to individuals. VAT refund functions are not possible in accordance with local laws of selected countries.
We do not sell physical goods for which a warranty service for exchange and return is provided. We respect the privacy of our customers, so we ask for the same in return. The service provides virtual services in accordance with the rules of the site. All taxes are paid in accordance with the laws of the resident country.
The deposit is non-refundable because it is used as a prepaid balance for a digital SMS verification service. The balance has no expiry date and can be used for future SMS orders. If an SMS is not received within the activation window, the cost of that specific order is returned automatically to your internal SMS-Box balance.
SMS-Box is responsible for receiving and displaying the SMS message if it is delivered to the selected number. We do not control whether WhatsApp, Telegram, Google or any other third-party service will accept a code, approve registration or request additional verification. If the SMS code is displayed in your SMS-Box account, the SMS-Box service is considered completed.
VoIP (Voice over IP) numbers are software-generated phone numbers that run over the internet, not physical SIM cards. Many verification services now detect and reject VoIP numbers. Our numbers are tied to real physical SIM cards and GSM modems — they cannot be detected as VoIP because they genuinely aren’t.
The most common reasons: (1) the service selected does not match the SMS sender — double-check the service name; (2) the 5-minute activation window expired before you entered the number; (3) the service is temporarily unavailable or has unusual blocking. Funds are returned automatically if no SMS arrives.
With a one-time number: no — after first use the service+number combination is unique to that customer. With a private dedicated number: yes — you can re-request as many times as you need during the rental period.
The balance deposit is non-refundable. However, if an SMS does not arrive within the 5-minute window, the cost is automatically refunded to your balance. You are only charged for successfully delivered SMS codes.
We guarantee the number is real and activated. We cannot guarantee that every third-party service will send an SMS — some services have unpredictable behaviour. Our success rate on major services is high, and funds are returned automatically if no SMS arrives.
