イギリスにおけるThree UKと旅行用eSIM

Three UKの概要

Three UK merged with Vodafone UK in 2025 to form VodafoneThree, and Three's site says it now runs on the combined Vodafone and Three network.

Three's bands and technology

An eSIM can only use Three if your phone supports at least one band in this table. Before you fly, open your model's spec page on the maker's site and compare its LTE and 5G band lists.

Three's coverage map

Three publishes its own coverage map. Look up the street or district you will stay in rather than the country as a whole, because coverage in town and out of town differs a great deal. The map shows Three's own network; a roaming plan may not get every technology it shows.

Who licenses Three

Mobile networks in United Kingdom are licensed, and their spectrum assigned, by the Office of Communications (Ofcom). The bands above are the ones it allocates. A problem with the local network's own service goes to the operator first; a problem with your eSIM plan comes to us.

当店で取り扱うプランのうちThree UKを記載しているもの

From the supplier record behind each package, 34 of the 101 plans we currently sell for United Kingdom declare Three UK as a network the profile can reach, at 5G. The figure comes from the same catalogue that prices the plan pages, and it moves when the supplier revises the record.

プランが特定のネットワークを名指ししない理由

Nearly every travel eSIM is a roaming product: the profile picks a network by an order the supplier sets, not by the buyer. If Three UK is weak where you are, try selecting EE or O2 or Vodafone UK manually in the network settings, and keep data roaming on for the eSIM profile.
