SIMSY

The SIMSY app is your gateway to a new mobile experience. SIMSY provides a mobile data service with a difference. Use our app to download our eSIM, order a physical SIM, top up your account and manage your mobile services.


With our app you can get your MCP key, which allows you to integrate the SIMSY mobile solution directly into your favourite AI tool whether that's chat GPT, Claude, a perplexity or anything else you might want to use.


• Use your MCP key to access the SIMSY MCP Server.
• SIMSY allows you to integrate connectivity with a suite of AI tools including Lovable, Windsurf, Databutton, Cursor, RooCode and Replit.
• Head to s-imsy.com to look at the available base applications and to see how you can use SIMSY to integrate with your other connected solutions.
The SIMSY app enables quick, easy and free remote access into any of your devices, whether it’s Raspberry PI, home automation system, video cameras, Nvidia Jetson devices, home networks or anything else you can think of.

You can also take your SIMSY SIM roaming, travel round the world with low cost data and only pay for the data you need to use. Your credit will not expire so you don't need to continually buy bundles.
