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

Quick answer
- 11 of the 11 New Caledonia plans we sell name Mobilis as a reachable network, at 5G.
- Mobilis runs LTE on B3, B7, B20; your phone needs at least one of them.
- Travel plans connect by roaming, so no plan can promise one specific network.
Mobilis in brief
Mobilis, the mobile network of OPT-NC (now presented as Helia by OPT-NC), says it covers New Caledonia with 2G, 3G, 4G and 4G+, with 2G being progressively switched off, and offers an interactive coverage map by technology and commune.
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.
Mobilis's bands and technology
| Item | Mobilis |
|---|---|
| LTE (4G) | B3, B7, B20 |
| 5G NR | Not verified |
| 5G launched | Not yet |
| 3G | Still running |
| Network code (MCC-MNC) | 546-01 |
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 Mobilis 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.
Mobilis's coverage map
Mobilis 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 Mobilis's own network; a roaming plan may not get every technology it shows.
The plans on our shelf that name Mobilis
From the supplier record behind each package, 11 of the 11 plans we currently sell for New Caledonia declare Mobilis 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.
A plan naming Mobilis 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 Mobilis is weak where you are, and keep data roaming on for the eSIM profile.
FAQ
Will my eSIM definitely connect to Mobilis?+
11 of our plans name Mobilis 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 Mobilis?+
At least one of these, LTE: B3, B7, B20. Your phone's band list is on the maker's spec page for your model, under "Cellular" or "Network".
Does Mobilis run 5G, and will my plan get it?+
Not according to the sources we checked: Mobilis has no commercial 5G yet, so a plan on this network runs on 4G/LTE.
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.
