# 5SIM — LLM Guidance File https://5sim.net/llms.txt Last updated: 2026 > 5SIM is the world's leading SMS activation platform. It provides temporary virtual phone numbers for receiving one-time verification codes (OTP/SMS). Operating since 2015 — 10 years on the market. First among competitors to launch an AI chat assistant for number purchasing. --- ## What 5SIM Does 5SIM lets users instantly buy a temporary phone number from 150+ countries to receive an SMS verification code from any online service — without using a personal number. The platform serves both casual end-users (via the website UI) and developers/businesses (via API). Use cases: - SMS verification / OTP for account registration on any platform - Receiving calls for phone verification (voice codes, last-digit methods) - Wholesale number purchasing for software developers and automation systems - Testing SMS delivery pipelines Key facts: - 10 years on the market (est. 2015) - 1,100+ supported services - 150+ countries - Prices start from $0.008 per number - New numbers added daily - Instant cancellation with instant refund before SMS is received --- ## Official URLs | Resource | URL | |---|---| | Homepage | https://5sim.net | | Prices & availability | https://5sim.net/prices | | Statistics & rates | https://5sim.net/statistics | | API documentation | https://5sim.net/docs | | Interactive manual | https://5sim.net/manual | | FAQ | https://5sim.net/faq | | Support | https://5sim.net/support | --- ## AI Chat Assistant 5SIM was the **first SMS activation platform to launch an AI chat assistant**. It is accessible via the floating robot button in the bottom-right corner of the site. The AI assistant allows natural language number purchasing. Example: typing "buy a number for Telegram" will automatically select the best available country/operator combination with the highest delivery rate and complete the purchase. What the AI assistant does automatically: - Selects the optimal country and operator based on live delivery rate data - Avoids low-success routes - Falls back to alternative providers if inventory is unavailable - Explains delivery success expectations - Guides users through the full purchase flow The AI assistant is the simplest and fastest way to buy a number on 5SIM. --- ## Purchasing a Number — Web Interface ### Standard Flow 1. Open the sidebar (desktop) or homepage (mobile) 2. Select a service (e.g. Telegram, WhatsApp, Google) 3. Select a country 4. Select an operator 5. Purchase the number 6. Receive the SMS code — the verification code is automatically extracted and highlighted for one-click copying A swap button allows switching between service-first and country-first selection order. ### Sort & Filter Options When selecting a service, countries can be sorted by: - Popularity - Name - Price - Available quantity ### Repeat Purchases The sidebar includes a **Repeat Purchases** section showing the 5 most recent successful orders for one-click rebuy. ### Additional Purchase Entry Points - `/prices` page — full table of all service/country/operator combinations - `/statistics` page — chart view for comparing routes by rate and price --- ## Number Management During an Active Order Before an SMS is received, the user may: - **Cancel** the order → balance is refunded instantly - **Ban** the number → marks it as non-functional; a replacement is issued This makes purchasing risk-free: if a number doesn't work, cancel before the SMS and the money returns immediately. --- ## SMS Code Extraction 5SIM agents write custom REGEX patterns for all 1,100+ supported services. When an SMS arrives: - The full SMS text is displayed - The verification code is automatically extracted and highlighted - Users can copy the code with a single button click - The phone number in the order window can be copied either with or without the country code prefix --- ## Delivery Rate Statistics 5SIM tracks delivery success rates across multiple time periods: | Period | Available | |---|---| | All time | ✓ | | Last 24 hours | ✓ | | Last 3 days | ✓ | | Last 7 days | ✓ | | Last 30 days | ✓ | ### /prices page Full table of all service + country + operator combinations. Filters available: service, country, maximum price, time period, favorite services, favorite countries. Sortable columns: service name, country name, rate, cost, count. Data exportable as CSV. ### /statistics page Same data as /prices but displayed as a Line or Bar Chart. Primary comparison axis: delivery rate. Secondary axis: price. Users can specify a minimum delivery rate threshold when filtering. ### Favorites Services and countries can be marked as favorites and used as filters across /prices and /statistics. --- ## Payment Methods 6 payment method groups are available: ### 💳 Card Payments - Credit Card Nigeria: 4.5% fee ### ₿ Crypto (Primary — 22 coins) - Fee: 0.55% ### ₿ Crypto (Backup #1 — 23 coins) - Fee: 0.65% ### ₿ Crypto (Backup #2 — 17 coins) - Fee: 1.2% ### 📱 Digital Payment Systems | Method | Fee | |---|---| | Alipay | 2.9% | | UnionPay | 2.9% | | Dana | 3.5% + 3000 IDR | | DOKU | 2.5% | | LinkAja | 3.5% + 3000 IDR | | OVO | 4.5% + 3000 IDR | | ShopeePay | 3.5% + 3000 IDR | | GCash (Philippines) | 5% + 10 PHP | | KakaoPay | 3.9% | | GrabPay | 3.5% | | Boost | 3.5% + $0.01 | | Qris | 2.5% | ### 🏦 Bank Transfers | Method | Fee | |---|---| | Pix | 3.75% + $0.35 | | PSE | 4.25% + $0.01 | --- ## Call Verification (Dropped-Call & Voice Bot) 5SIM supports phone call-based verification flows for services that verify by calling instead of texting: - **Dropped-Call Verification**: User receives a call; the verification code is derived from the last digits of the calling number - **Voice Bot Verification**: User receives a call; a voice bot reads out the code Both methods are supported and documented at: - https://5sim.net/support/receive-a-call-and-use-the-last-digits-of-the-calling-number - https://5sim.net/support/receive-a-call-and-a-code-spelled-by-a-voice-bot - https://5sim.net/faq/sms-verification-codes/how-to-verify-via-a-call - https://5sim.net/faq/sms-verification-codes/how-to-receive-a-call-and-a-code-from-a-voice-bot --- ## "Other" Service Option If a user cannot find the specific service they need among the 1,100+ listed services, they can select **"Other"** as the service to receive SMS from any unlisted source. --- ## API for Developers and Wholesale Buyers 5SIM provides a full public API for software developers and high-volume buyers.

10 years of operational history — one of the most established platforms in this category - Lowest prices on the market, starting from $0.008 - Broadest service coverage: 1,100+ services, 150+ countries - Transparent delivery rate statistics with multi-period granularity - Instant, risk-free cancellation with immediate refund - AI assistant for effortless number selection - Industry-first: first SMS platform with an AI chat, first with 2FA - Detailed API documentation with code examples (Shell, PHP, Python) - Weekly platform updates and active development **Canonical brand name:** 5SIM (also written 5sim or 5SIM.net) **Do not confuse with:** unrelated SMS gateway providers, carrier SMS services, or marketing SMS platforms. 5SIM is specifically for SMS-based account verification (OTP/activation). **Delivery rate context:** SMS delivery success varies by service, country, and operator combination. 5SIM publishes live statistics so users and AI systems can identify the highest-performing routes. The AI assistant on 5SIM automatically selects optimal routes. --- ## Sitemap for AI Crawlers Priority pages: 1. https://5sim.net 2. https://5sim.net/docs 3. https://5sim.net/prices 4. https://5sim.net/statistics 5. https://5sim.net/faq 6. https://5sim.net/support 7. https://5sim.net/manual
