Elevate Your Testing Experience
It's time to elevate your eSIM testing experience. Traditional approaches mean testing friction: processes reliant on specialist engineers and outdated tools. simcheck.ai offers a new way. Chat with AI to run sophisticated tests-just describe what you need in plain English. AI interprets your intent, builds the test, and executes it globally. Test SGP.22, SGP.32, and roaming scenarios without technical expertise-effortlessly.
AI-Driven eSIM Testing Intelligence
Conversational Testing
Stop wrestling with complex configurations. With simcheck.ai, simply chat in plain English-say "Test SGP.32 provisioning for IoT devices in Germany" and AI builds the test automatically. Our platform translates your requirements into comprehensive test plans, intelligently selecting optimal endpoints and executing across our global network-instantly.
Intelligent Diagnostics
Drastically shorten your time to resolution. simcheck.ai automatically diagnoses issues and suggests fixes. When problems arise, AI instantly triggers targeted tests and provides root cause analysis-learning from every run to proactively detect failures before they impact users.
Dedicated IoT & eSIM Assurance
Ensure your global IoT deployments connect reliably, every time. simcheck.ai provides specialized testing for NB-IoT, LTE-M, LTE Cat-1 BIS, plus SGP.32 eSIM profile provisioning validation for headless IoT devices.
Seamless Integration: API & Automation
Integrate eSIM testing directly into your operations and automate with unprecedented ease. simcheck.ai offers robust API access, allowing your engineering teams to trigger eSIM profile tests from NOC tools, CI/CD pipelines, or any custom system.
AI Watchtower
Move beyond reactive fixes. simcheck.ai acts as your 24/7 AI watchtower, autonomously monitoring global eSIM performance. AI learns your network baselines, detects anomalies in real-time, and leverages collective intelligence from global test data to predict issues before they occur-delivering actionable insights that keep you one step ahead.

Get StartedWhat is AI-powered eSIM testing?
eSIM testing verifies that an eSIM profile can be downloaded, installed and enabled on a device, and that the subscription then attaches to the right networks and delivers working data, SMS and voice — at home and while roaming. SimCheck.ai runs those checks on real cellular modems with real eSIM profiles on live networks, and lets you create them in plain English: describe what you want to verify, and the platform's AI turns it into a test, runs it where you need it and explains the result.
Instead of shipping SIM cards, coordinating partners or waiting for a specialist engineer, any team member can check a profile, a roaming partner or a 5G SA launch in minutes, and turn that check into scheduled monitoring.
What you can test
| Area | Examples | Learn more |
|---|---|---|
| eSIM provisioning | SGP.22 consumer profiles, SGP.32 IoT profiles via an eIM, download limits | eSIM testing, SGP.32 IoT testing |
| Roaming | Lock to each partner network by PLMN, data/SMS/voice while roaming, roaming matrix | Roaming testing |
| Voice & messaging | VoLTE calls with setup time and recordings, SMS delivery, calling cards | VoLTE & voice testing |
| IoT connectivity | NB-IoT and LTE-M attach, MQTT round trips, persistent attach | IoT connectivity testing |
| 5G and performance | Force 5G SA or NSA, iperf3, speed tests, latency | 5G SA testing |
| Travel eSIM quality | Destination-by-destination checks and monitoring | Travel eSIM monitoring |
Every test is available as a one-click Quick Test, an interactive phone session with Test Like A Mobile, or an automated, scheduled flow — and through the API and MCP for AI assistants.
Frequently asked questions
What does SimCheck.ai do?
SimCheck.ai is an AI-powered eSIM testing and assurance platform. It runs eSIM provisioning, network attach, data, SMS, voice, roaming and 5G tests on real modems with real eSIM profiles on live networks, and lets you create and run those tests in natural language.
Do I need my own devices or SIM cards?
No. You upload eSIM profiles as activation codes or QR codes and run tests on the SimCheck network of edge gateways. You can also connect your own edge device with a cellular modem; tests on your own devices are free on every plan.
Does SimCheck.ai support SGP.32 IoT eSIMs?
Yes. Profiles can be installed through SGP.32 using an eIM, or through an SGP.22-style LPA, so you can validate both consumer-style and IoT eSIM provisioning on the same platform.
Can I test roaming partners in specific countries?
Yes. Tests can be locked to a specific operator by PLMN code and radio technology, run across several locations at once, and summarized in a roaming matrix report of home versus visited operators.
