SimSms is an SMS receiving and account activation service with a Russian-language interface, positioned around “activating accounts for any service via SMS.” The site provides entry points for selecting numbers by country and service, and lists many platforms that can receive verification codes, including OpenAI, Google, Facebook, Amazon, Apple, Alibaba, Discord, LinkedIn, and more. In addition to SMS, the page also mentions capabilities related to “voice verification codes,” “incoming call numbers,” and “call forwarding.”
In terms of channels, SimSms is primarily an SMS code receiving service, while also supporting voice verification codes and call forwarding. Its geographic coverage appears broad: the text lists 69 countries/regions, including Canada, the United States, the United Kingdom, Germany, France, Hong Kong, Singapore, Japan, South Africa, and others. For API access, it provides HTTP GET endpoints with JSON responses, accepting parameters such as service, country, apikey, operator, and redirectphone. It can also specify certain Russian, Kazakh, and Ukrainian operators. Performance information is limited: it only states that a single IP can have up to 100 concurrent orders and recommends a 250 ms interval between orders. It does not disclose delivery rates, average code receiving time, or any failure compensation mechanism.
The captured page content does not include a complete pricing table. The only visible pricing information is that numbers with call forwarding cost USD 50 each, and that SIM card balances need to be topped up by USD 10 to 20 for forwarding. The page seems to include fields showing online quantity and pricing by service, but the specific values were not captured in the text. As a result, pricing transparency is limited, making it difficult to directly assess the actual cost of receiving verification codes across different countries and platforms.
Its advantages are broad country and service coverage, relatively straightforward API documentation, and suitability for bulk or script-based integration. Support for operator selection and call forwarding also makes it more flexible than a typical SMS receiving site. The drawbacks are equally clear: there are no public delivery-rate or stability metrics, and no visible information about payment methods, support channels, SLA, or privacy compliance. The API passes the apikey via GET, which is a fairly basic security design. In addition, using SMS receiving services to register on third-party platforms may violate those platforms’ terms, so businesses should conduct a compliance review before use.
It is better suited to developers, testers, or gray-release operations teams conducting multi-country verification-code flow testing, rather than as an enterprise-grade compliance verification service. The captured content does not indicate how well it works from China; network connectivity, payment availability, and account risk controls are all unknown. If you need a more compliant and auditable alternative, consider Twilio Verify, Vonage Verify, MessageBird, or Sinch. For temporary-number SMS receiving, similar alternatives include SMS-Activate and 5sim.
