Phone overheating during extended use
Warm is normal. Navigation, hotspot, video calls, and streaming work your phone's processor, radio, and battery hard, and doing them outdoors in a hot climate adds to it. A phone in a car mount in the Moroccan or Australian sun will run warm regardless of which line is carrying data.
More detail
Two things to know. First, none of this is caused by the eSIM; a second line adds a small amount of background radio activity, nothing more. Second, your phone protects itself: when it gets too hot it dims the screen, slows down, may turn off the flash or camera, and eventually shows a temperature warning and pauses until it cools. That's a safety response, not a fault, and not something to push through.
What helps: take it out of direct sun, remove a thick case, pause hotspot or downloads for a few minutes, and let it cool before charging. If you're tethering a laptop for hours, keep the phone in shade and plugged in.

Since an eSIM functions similarly to a traditional SIM, your service provider may swiftly deactivate your service in the event that you misplace or have your device stolen. Do not hesitate to contact them immediately.
Be sure that your network plan allows for using it as a Personal Hotspot and that your provider has enabled it if you are unable to locate or activate it. To reconnect another device to Personal Hotspot, you must first restart both the iPhone or iPad that is providing the service and the second device. Verify that you are using the most recent version of Apple's iOS or iPadOS.
