CTM and travel eSIM in Macau
CTM is one of the networks your eSIM may use in Macau. Here is who actually decides which network you get, and what to do with that.

Quick answer
- 75 of the 75 Macau plans we sell name CTM as a reachable network, at 4G and 5G.
- CTM runs LTE on B1, B3, B5, B8, B41 and 5G on n78; your phone needs at least one of them.
- Travel plans connect by roaming, so no plan can promise one specific network.
CTM in brief
CTM is a mobile network operator in Macau, and one of the networks a travel eSIM may reach through roaming.
We are not a reseller for this operator and we have not run our own field speed tests. The band and network details below come from the sources listed at the end of the page.
CTM's bands and technology
| Item | CTM |
|---|---|
| LTE (4G) | B1, B3, B5, B8, B41 |
| 5G NR | n78 |
| 5G launched | Live |
| 3G | Shut down |
| Network code (MCC-MNC) | 455-01 |
Checked against the sources on 2026-10-12. Only the bands a source confirmed are listed; the network may run others too.
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.
The plans on our shelf that name CTM
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.
A plan naming CTM means the network sits in the list the profile may choose from. It does not mean your handset will stay on it. The priority order is the supplier's, and the signal where you stand decides.
Why plans do not name a fixed network
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.
FAQ
Will my eSIM definitely connect to CTM?+
75 of our plans name CTM as reachable, but that is not a guarantee. Travel plans run over roaming agreements, so the network depends on the supplier behind the plan, your device and where you are.
Which bands does my phone need for CTM?+
At least one of these, LTE: B1, B3, B5, B8, B41; 5G: n78. Your phone's band list is on the maker's spec page for your model, under "Cellular" or "Network".
Does CTM run 5G, and will my plan get it?+
Yes. CTM has run commercial 5G, on n78. A travel plan only gets it when the plan permits 5G, your phone supports one of those bands, and you are inside 5G coverage. Miss any one and you fall back to 4G.
How do I see which network I am on?+
Check the carrier name at the top of the screen, or open the mobile-network settings and look at the operator list. If signal is poor, try selecting a network manually instead of automatic, but only one your plan actually supports.
