ORoaming: Why haven't any other smartphone manufacturers built this yet?

I‘m staying in a remote Italian region, mobile internet is almost nonexistent because antennas overbooking or something similar. I bought a data-only eSIM from Airalo, that is able to connect to 3 (!!) different carriers, one of which works extremely well around here. It’s not cheap - 16€/10GB - but the convenience is top notch. There are many data-only eSIM global providers out there, you just have to search for them with the right keywords. I believe those services are mainly aimed at digital nomads.

My experience with eSIM has been with my Apple phone. I have an app that basically does this - it's Ubigi and I've generally been happy with it. I installed it from the App Store.

As to why Apple themselves don't have such an app, I would have to assume that it's because they don't see reselling of mobile data as a core competency nor a profitable business line.

I just have a provider (Google Fi) that works worldwide. I have no desire to negotiate a deal with anyone. Each spend point is a pain point. Prefer a single aggregate plan. I put my money in and I go anywhere in the world with my phone. Works great. Been fine for me for over five years.

All Chinese smartphone brands have this. Huge reason to buy one of those rather than other brands.

I like it. Thanks for sharing. Good for my old folks who get ripped off at kiosks and local deals.

The costs with these services generally are exceptionally higher than paying for a local mobile plan in each region
