And even where there is nominal 4G coverage, it's patchy. I live in London, which is supposed to be pretty well covered by 4G, but much of the time I can't get it.
On the other hand, 3G should be fine in Scotland. Sure, a lot of Scotland has no cellphone signal at all, but that's because a lot of Scotland is wilderness. If the OP's daughter is actually studying in a town, the mobile signal should be fine. And there will be plenty of free WiFi hotspots - coffee shops, bars & McDonalds - if she wants to voip home to ask for money.
