香港におけるCSL / HKTと旅行用eSIM

CSL / HKTの概要

csl says its 5G uses dedicated 3.3, 3.5 and 4.9 GHz spectrum (plus 700 MHz and 26/28 GHz holdings), so it needs no dynamic spectrum sharing with 4G.

csl's bands and technology

An eSIM can only use csl 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.

csl's coverage map

csl 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 csl's own network; a roaming plan may not get every technology it shows.

Who licenses csl

Mobile networks in Hong Kong are licensed, and their spectrum assigned, by the Office of the Communications Authority (OFCA). 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CSL / HKTを記載しているもの

From the supplier record behind each package, 68 of the 93 plans we currently sell for Hong Kong declare CSL / HKT as a network the profile can reach, at 4G and 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 CSL / HKT is weak where you are, try selecting China Mobile Hong Kong or SmarTone manually in the network settings, and keep data roaming on for the eSIM profile.
