Simcardo launches the Connectivity Planner inside ChatGPT

Today we are announcing that Simcardo Connectivity Planner is live in the OpenAI ChatGPT Apps directory. Travelers can now plan how much mobile data they will need, compare connectivity strategies, and get a destination-specific checklist — directly inside any ChatGPT conversation, without leaving the chat and without creating an account.

The app is intentionally read-only and advisory. It does not sell anything inside ChatGPT, does not link conversations to a Simcardo customer account, and does not push you toward a specific provider. We built it because connectivity decisions are made before a trip, in the same conversational space where travelers already plan flights, accommodation, and activities — and the existing eSIM industry has no good answer for that planning surface.

Why ChatGPT, and why now

In the last twelve months, ChatGPT has quietly become a primary travel-planning surface for tens of millions of people. The questions people ask in that surface — "how much data do I need for nine days in Japan with maps and video calls?", "is roaming worth it for a three-week Europe trip?", "what should I set on my phone before landing in Morocco?" — are not questions that fit neatly into a vendor's product page. They are advisory questions. They deserve advisory answers.

The OpenAI Apps SDK, launched earlier this year, gave platform vendors a way to expose tools to ChatGPT users without bolting on payment flows or hijacking the conversation. That fit our model exactly. We had already been investing in the same problem space on our own platforms — usage estimators, destination guides, compatibility checks — and bringing those tools into ChatGPT was the natural next step.

What the Connectivity Planner does

The app exposes three tools to ChatGPT, all of which can be invoked through normal conversational language:

• Estimate trip data usage. Given a destination, trip length, and a description of what the traveler plans to do online, the planner returns a total GB estimate with a per-activity breakdown (maps, social, video calls, streaming, browsing).
• Compare connectivity strategies. Travel eSIM, international roaming, Wi-Fi-first, and local SIM are scored against the user's specific trip profile. The output is a side-by-side comparison with cost ranges, friction, and reliability.
• Destination-aware checklist. Coverage notes, common network issues, and recommended phone settings, all tailored to the country in question.

All three tools are declared readOnlyHint: true in the MCP manifest. Nothing is written, nothing is purchased, no personal data flows back into Simcardo's customer systems. We treat the conversation as ephemeral by design.

The vendor-neutral default

A natural question, when a brand ships an advisory tool, is whether the advice is honest. Our answer is structural rather than rhetorical: the Connectivity Planner has no checkout, no upsell, and no path to revenue inside ChatGPT. The four strategies it compares — eSIM, roaming, Wi-Fi, local SIM — include options that route users away from Simcardo. That is a deliberate choice. If a three-week trip across one country with reliable hotel Wi-Fi is best served by a local SIM, the planner will say so.

Our commercial bet is that travelers who get useful, vendor-neutral advice today are the travelers who choose us when they actually need an eSIM tomorrow. The transaction lives on simcardo.com and in our native iOS and Android apps. The planning surface stays clean.

What this means for the broader market

The travel eSIM category is now four years into rapid growth, and the consumer-facing playbook has converged: a search box for the country, a card grid of plans, a checkout flow. That works, but it answers only the last 15% of the journey — the purchase. The first 85% — figuring out how much data is needed, whether eSIM is even the right strategy, what to set on the phone before the flight — is largely unserved by the category.

Bringing that planning layer into the conversational surface where travelers already are is, we think, the next chapter for the category. ChatGPT is one such surface; voice assistants, in-car systems, and travel-planning agents will be others. The shape of the answer is the same in each: stop pretending the planning step doesn't exist, and stop hiding it behind a checkout funnel.

Availability and roadmap

The Connectivity Planner is available today in the OpenAI Apps directory and accessible directly via the canonical landing page at simcardo.com/en/apps/connectivity-planner. The Apps SDK is rolling out across ChatGPT Free, Plus, Pro, and Business plans on OpenAI's standard schedule.

Near-term, we plan to deepen the country-level network notes (currently strongest for the top 60 travel destinations), add a multi-stop trip mode for itineraries that cross several countries, and expose the same tools through MCP for third-party agent ecosystems. We will share concrete benchmarks on accuracy and adoption in a follow-up post once we have meaningful production data.

Travelers can start using the Connectivity Planner today by opening it directly in the ChatGPT Apps directory, or by reading the full overview on simcardo.com.
