Useful information to bear in mind. Thanks.
Something to bear in mind with Lebara (I've been with them for a few years now) is that non-geographic international numbers aren't supported at all. I'm not just talking about the international inclusive minutes here... you can't even pay for a call to an international non-geographic number; it simply won't connect. Crazy situation and caused me much frustration when trying to call an airline about a reservation I needed to change and the only numbers they published were toll-free international (being non-geographic, I couldn't use them!)
Thankyou for explaining (y)
5G sim will work in the phone and it will get 4G/3G/2G coverage if 5G is unavailable; you just won't be able to use 5G speed/network.
Are you joking? Per my last answer, a 5G SIM like in this offer will work fine where there is only a 4G signal or in a 4G phone. I don't think she does.
