SMS activation
OnlineSIM.ru
OnlineSIM.ru offers virtual numbers for receiving SMS through one-time use or rentals, with the provider describing its role as a marketplace operator and technical intermediary. Its terms exclude refunds for network outcomes such as non-delivery, while a separate policy says refund requests are reviewed case by case.
This is relevant for media buyers assessing SMS access or API workflows who can account for prepaid credits and third-party network exposure.

What does the virtual-number marketplace provide?
The marketplace is for browsing, ordering, managing, and using services, while the provider says its main service is receiving messages on virtual numbers. The provider describes numbers for registrations on websites, online services, and apps, and says it serves testing, work, and data-protection purposes.
The provider presents one-time SMS reception separately from using a number for several days or weeks. It also says each purchased number is used by one client, is not reused, and exposes codes only to that client. Those privacy statements are the provider’s descriptions of its number handling.
Marketplace Services include availability listings, ordering, technical integration, usage status, payment settlement, and support, according to the provider’s terms. The provider identifies itself as an intermediary; third parties and external networks supply the underlying services.
How do activations and API messages work?
The API provides access to SMS-receiving services and supports API-key authentication, among other authentication methods. Access is limited to registered users with an OnlineSIM profile, according to the API documentation.
The documentation distinguishes number rentals, which can receive SMS from multiple senders, from single-service activations. In a single-service operation, users cannot change the selected service. The provider describes that operation’s short time window as 15 minutes for most services.
For active operations, the API can forward messages to a URI configured by the user. Responses are returned in JSON or TXT, depending on the method and results. The provider says it may limit requests by frequency or concurrent-request count, and its terms subject API access to applicable requirements and limits.
How do prepaid credits and refunds interact?
The provider describes a free trial on its homepage. Clients prepay through payment methods available on the platform, with prepaid amounts recorded as account credits, according to the offer terms. Costs may change without notice; applicable taxes and third-party processing fees are assigned to the client.
Refunds are not automatic: the provider says requests are reviewed case by case. Its terms exclude refunds for network outcomes including non-delivery, delay, blocking, rejection, or a number not being accepted. The refund policy separately excludes network outcomes caused by third parties or external networks, to the extent permitted by law.
A written request must identify the account, explain the reason, and include payment details sufficient to identify the transaction. The provider says sufficiently detailed requests are reviewed within 5 business days of receipt. If approved, a refund is based on the account balance at review, subject to exclusions and lawful set-off, and is returned to the original payment method unless that is technically impossible or restricted by payment-provider rules. The policy says processing typically takes 3–5 business days after approval, with bank and payment-provider crediting times varying.
What should you check before relying on an API?
Before relying on an SMS API, ask the provider how it handles the specific countries and services needed for your workflow. Availability can change by destination and service, so request the current selection details rather than assuming broad coverage applies to every combination.
Clarify how each activation and rental is priced, and how rental periods are presented before ordering. Ask which payment methods the platform accepts and what credit procedure applies if a paid activation returns no code.
For API use, request examples for the intended operation and written limits on request frequency and concurrent requests. Confirm how messages are delivered to your configured destination and what response formats apply to the methods you plan to use.
Which documented functions cover common SMS needs?
The provider’s terms list marketplace functions that include availability listings, ordering, usage status, payment settlement, and support. This puts several parts of the service workflow within the marketplace’s stated scope.
The offer includes one-time SMS reception and numbers used over several days or weeks. It also describes short-term and long-term phone rentals. The API documentation distinguishes these access patterns rather than describing one number-use model.
API features include key-based authentication, forwarding messages from active operations to a user-configured URI, and JSON or TXT responses. The provider lists online support chat and email as contact routes.
Which terms narrow access and recovery?
The offer terms place lawful-use responsibility on the client and allow the provider to request identification. If requested information is not supplied, the provider says it may suspend or terminate access or block the account.
- Account Information is retained for 30 days from the last purchase activity; without a new purchase, the account and information are permanently deleted.
- Service Usage Records are retained for 30 days from creation, subject to longer retention required or permitted by law.
- Account termination does not create a refund right, and remaining balance is non-refundable if the account is automatically deleted under the Terms or Data Retention Limitation Policy, including due to inactivity.
- The platform does not support messages from banks, payment services, or other financial institutions.
- Free-number messages are accessible to other site users, while free-number quantity and country availability are limited.
- The provider says API requests may be limited by frequency or concurrent-request count, and does not guarantee uninterrupted or error-free platform operation.
Several details are missing; they are listed under What we could not confirm.
Who can work with prepaid number access?
OnlineSIM.ru may fit workflows that need virtual numbers for registrations, testing, work, or data protection, as described by the provider. Its stated offer includes one-time SMS reception and rentals lasting several days or weeks.
Free numbers are described as suitable for testing, but their messages are not private and can be accessed by other site users. The platform excludes messages from banks and other financial institutions, so those workflows fall outside its stated support.
Which SMS terms should alternatives match?
Compare services by the country and service coverage relevant to your workflow, how per-number charges and rental periods are presented, and whether failed-code outcomes qualify for refunds. For API use, compare request limits, authentication, and message delivery options. Also check payment methods and the provider’s stated use conditions before choosing between services.
What we could not confirm
- Country selection: how buyers choose a specific country-and-service combination.
- Individual activation pricing: the pricing basis for each number.
- Rental pricing: the price for each rental period.
- Payment options: which payment methods the platform accepts.
- No-code outcome: the exact credit procedure for a paid activation.
- Permitted services: the full list and detailed use restrictions.
What do the API and refund terms answer?
Does API access require an account?
Yes. The API is available only to registered OnlineSIM users with an OnlineSIM profile, according to the API documentation. The documentation also describes API-key authentication among its supported authentication methods. Buyers should distinguish access eligibility from the specific request and operation limits.
Can an API operation change its selected service?
No. Users cannot change the service during a single-service operation, according to the API documentation. The provider describes rentals separately from single-service activations, so buyers should check which operation matches the intended workflow before integrating it.
How can active-operation messages reach another system?
The API can forward messages from active operations to a URI configured by the user. Its responses use JSON or TXT, depending on the method and results. The documentation also says requests may be limited by frequency or concurrent-request count.
Does the provider automatically refund a failed activation?
No. The provider says refunds are reviewed case by case rather than issued automatically. Its offer terms exclude refunds for network outcomes including non-delivery, delay, blocking, rejection, or number non-acceptance.
What must a refund request include?
A request must identify the account, state the reason, and include payment details sufficient to identify the transaction. The provider says it reviews sufficiently detailed requests within 5 business days of receipt. Approved refunds are returned to the original payment method unless technically impossible or restricted by payment-provider rules.
How long can an approved refund take?
The provider says approved refunds are typically processed within 3–5 business days after approval, while bank and payment-provider crediting times may vary. This is separate from the stated review period for a sufficiently detailed request.
Does the marketplace fit your SMS workflow?
Fits if you need virtual-number SMS reception, rentals, or API access and accept prepaid credits alongside third-party network exposure.
Probably not if the workflow requires messages from financial institutions or private access to messages on free numbers.
Main risk… prepaid credits do not remove the provider’s exclusions for network outcomes, while account deletion after inactivity can leave remaining funds non-refundable. Check the applicable refund terms, operation limits, and use conditions before signing up.
