Hardly major, but our[0] entire stack except the frontend is Rust. [0] https://dtmf.io/

The app actually supports iOS already (it's built with Flutter) but we changed legal entity and made a mistake with the app transfer process, so it's temporarily unavailable. We're…

The problem is that free public WiFi is wildly variable in quality, whereas 4G is usually quite good. Most of the time I just tether even if there's WiFi available since I can use …

The UK notably doesn't, and most providers are still doing "roam like at home" with the EU despite the UK having left.

Most likely they have heard of the MVNO/"service reseller" LycaMobile, but how does that respond to their comment at all? LycaMobile still require you to register your ID with them…

The physical SIM numbers are SIMs from major UK providers, and are never re-used (for clarity: if you buy a SIM number, you get a SIM that has never been used by anyone else, and i…

The virtual numbers come from a few different suppliers, one being Twilio for example. The physical SIM numbers are infrastructure that we built, using racks of GSM modems, SIM car…

Thanks - we'll add this information. The per-minute charges are fixed for a given number type for inbound calls. They're cheapest for landline numbers (e.g. just under EUR 0.01 per…
