Unless you're using facetime or skype or something, your calls go out over regular signal not data so don't worry arista - you won't lose your call if your 5g (or 4g, or any other g) drops .

I'm just impressed that I get 4g pretty much everywhere these days. Seems to have happened really suddenly. Like right now I'm half way down the M6 in the middle of nowhere and getting full 4g . And last week I was on one of the Scottish Islands where I used to barely get a signal, but again, full 4g. Fum zup.
