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 hoping to have it back on the store in the n

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 my data plan in most countries and the WiFi is usually

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 in countries that have that rule.

Sorry! We're always adding new number types and countries though, so keep an eye.

You rent a virtual mobile, landline or toll-free phone number, or a physical SIM, via the website or Android app. The phone number is then yours as long as you keep paying the rental fee. (After you delete it or stop paying, we don't g

We only verify them for completeness; then we submit them to the relevant regulator and wait for them to give the documents the OK. We don't assign the phone number until we get the OK from the regulator.

If you re-read what I wrote, or perhaps quote the whole thing, you'll see that I was referring to the SIM, not to the phone number. Of course unless phone numbers perpetually get longer, they have to eventually get re-used. We don&#x27

It requires infrastructure, so it's not trivial, but we're investigating some options. Obviously it would only be practical in other countries that don't require SIM registration, or if they do, it needs to be possible to do

In the UK, a SIM card can be purchased without registration. We simply allow you to do that online and give you remote access to your phone (modem). One SIM card and one modem is used by one customer. It isn't really any different to w

We comply with these regulations. To get a German landline number via our service, you must provide proof of an address in the same locality, as well as proof of ID. We supply this to the regulator, and once they approve it, we provide the

You can keep a phone number as long as you like. If you accidentally delete it or allow it to expire, then we can probably , on a best-effort basis, recover the phone number for you if you alert us quickly after you make the mistake. Once

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 it will never be used by anyone else after you). From the per

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 card switching devices, and our own software to manage everythi

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 minute for a UK landline), very slightly more exp
