United Kingdom: is an eSIM better than a local SIM?

For most travellers, yes. A local SIM in United Kingdom means finding a shop once you have landed, usually with ID in hand, and it leaves you on a single carrier. An eSimHero eSIM installs before you travel, works the moment you arrive, and reaches 3 networks — 3, EE, O2 — so your phone can move to whichever one has signal. Your usual number stays active on the same phone throughout.
