New Caledonia: Mobile Coverage & Carriers
New Caledonia has one major mobile network operator, OPT-NC, which operates under the Mobilis brand. The network supports 3G, 4G/LTE, and 5G services on a commercial basis. For LTE connectivity, roaming devices typically connect to bands B3 (1800 MHz) and B28 (700 MHz), while 5G services operate on the n78 band at 3.5 GHz.
Regarding eSIM availability, local eSIM issuance by carriers in New Caledonia is currently being verified, and information on this capability remains limited. Travelers and roaming users should confirm eSIM support options with OPT-NC or their home carriers before arrival. Connection quality and coverage may vary depending on location within the territory.

Compiled from public-record telecom facts (the MNO roster, commercially-launched 3G/4G/5G generations, deployed travel-relevant bands and local-eSIM support) and verified June 2026; see the source we compile this country from. This country's connectivity row is currently low-confidence (small / island / single-operator / fast-changing market), so treat the carrier, band and 5G details as a starting point we are still verifying.
