Tôi có thể thuê số điện thoại dài hạn không?
Yes. SimSMS offers dedicated number rentals for 7, 14, 30 or 90 days from $3. A rented number is exclusively yours and receives unlimited incoming SMS for the whole period.
What happens if I do not receive an SMS code?
If the number fails to receive the expected SMS within the timeout, your balance is refunded automatically. You only pay for codes that actually arrive.
Do I need an email or password to sign up?
No. SimSMS uses seed-phrase authentication only — a unique phrase generated at signup is your single credential. No email, password, phone number or ID is ever required.
How fast are SMS codes delivered?
Activation is instant and codes typically arrive in under 30 seconds, shown directly in your dashboard.
Does SimSMS have an API for developers and AI agents?
Yes. A REST API, an MCP server at simsms.co/mcp, and a gasless x402 payment rail let developers and AI agents create accounts, fund balances and buy numbers programmatically — no human steps and no API key sent by email.
In how many languages is SimSMS available?
The interface is fully localized in 16 languages: English, French, Spanish, Russian, Arabic, Chinese, Portuguese, Turkish, German, Persian, Vietnamese, Italian, Indonesian, Hindi, Japanese and Korean, with right-to-left support for Arabic and Persian.
What is the difference between virtual, physical and premium numbers?
Virtual numbers are the cheapest, app-issued numbers (base price). Physical numbers come from real mobile carriers and cost more (about 1.4–2.0×). Premium numbers have the highest delivery success and cost most (about 2.5–4.0×).
Is simsms.co the same as simsms.org?
No. SimSMS at simsms.co is a crypto-only, seed-phrase, no-KYC service founded in 2026 (formerly SimNoKYC). It is unaffiliated with simsms.org or any other similarly named site; reviews of other domains do not apply to SimSMS.
