マカオにおけるCTMと旅行用eSIM

CTMの概要

CTM is a mobile network operator in Macau, and one of the networks a travel eSIM may reach through roaming.

CTM's bands and technology

An eSIM can only use CTM 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.

Who licenses CTM

Mobile networks in Macau are licensed, and their spectrum assigned, by the Office for the Development of Telecommunications and Information Technologies (as listed by Wikipedia) (GDTTI). 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CTMを記載しているもの

From the supplier record behind each package, 75 of the 75 plans we currently sell for Macau declare CTM 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 CTM is weak where you are, try selecting China Telecom (Macau) or SmarTone Macau manually in the network settings, and keep data roaming on for the eSIM profile.
