EsimTao
Work out how much travel data you need, check if your phone supports eSIM, and compare plan prices.
Connects to EsimTao's travel eSIM reference data. Muse can estimate daily and total GB for a trip, check whether a specific phone or tablet model supports eSIM by region, suggest a plan type for 180+ destinations, resolve regional bundle coverage, and walk through QR or manual installation steps.
Try asking Muse: "I'm going to Japan for 10 days with my iPhone 15 and I'll use maps and some video, how much data do I need and which eSIM plan fits?"

Open ChatGPT settings
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
- 2
Turn on developer mode
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
