🇬🇧 Wielka Brytania

Yes. The UK has full eSIM support across all four major carriers — EE, O2, Vodafone, and Three. GoSIM UK eSIMs work on any eSIM-compatible device including iPhone XS and later, Samsung Galaxy S20+, and Google Pixel 3+.

GoSIM UK plans connect to EE, O2, Vodafone, or Three depending on the plan. EE consistently ranks as the UK's best network for coverage and speed. All four networks provide strong coverage in London, Edinburgh, Manchester, Birmingham, and major cities.

For a 7–10 day visit with typical tourist use (maps, social media, messaging), a 5–10 GB plan is comfortable. If you're working remotely, streaming, or travelling extensively by rail between cities, consider a 15–20 GB plan. London's Tube has growing WiFi coverage, but above-ground travel relies on mobile data.

Yes. GoSIM UK plans work across all four nations — England, Scotland, Wales, and Northern Ireland. Coverage in remote areas like the Scottish Highlands, Snowdonia, or the Outer Hebrides can be limited, but all major towns and cities are well-covered.

For most non-EU visitors, yes — roaming rates from carriers outside the EU/EEA in the UK can be significant. A GoSIM UK eSIM provides affordable local rates, often cheaper than single days of international roaming. EU visitors may have roaming rights on their home plans, so check your carrier first.

Signal in the London Underground is expanding but not universal. Most Tube stations on the Elizabeth line, Jubilee line, and several others have connectivity. Above-ground sections and overground rail are fully covered. GoSIM connects to UK carrier networks that provide available Underground signal.

GoSIM UK plans range from 1 day to 30 days. Plan duration begins from first activation when your phone connects to a UK network, not from purchase. Buy ahead and lose nothing.
