EG25 is an IoT modem and those tend to expose some extra functionality such as HTTP clients or TTS synthesis over AT commands. Some even document how to compile and run software on them - though of course it's only about the application CPU and not the actual modemy stuff that runs on separate DSPs with proprietary signed Qualcomm firmware.

Most (all?) standalone modems are basically screenless smartphones/SBCs with integrated modem these days.
