New Zealanders will be able to text each other from anywhere in the country, regardless of cellphone reception, by the end of this year due to Space X's latest satellite launch - which telco company One NZ has taken advantage of.

Last summer, Cyclone Gabrielle revealed vulnerabilities in parts of the country's mobile phone network when some towns were cut off for days when communication was critical.

This issue should be fixed, however, by the end of 2024 as the One NZ mobile network promises to allow your phone to operate like a satellite phone - enabling you to contact loved ones or emergency services from even the most remote locations.

One NZ chief executive Jason Paris explained the science behind the new mobile upgrade to Summer Breakfast this morning.

"We're strapping cell towers to rockets, then firing them up into space with Space X and then when they're in lower orbit they beam back to Earth - including New Zealand - a cell signal," said Paris.

"So when you're out and about, as long as you can see the sky and you have a smartphone in your hand you'll be able to have connectivity."

Users will be able to gain access to text messaging services this year, but One NZ plans to unlock the ability to use satellite voice and data by 2025.

Paris agreed with the sentiment it would be a game changer in emergencies like Cyclone Gabrielle, which cut off several small towns in Hawke's Bay and Gisborne from any contact outside the township.

"The cell towers weren't impacted but the power to the cell towers - that was the problem last time. So that is a safety issue when you can't get in touch with emergency services or tell your loved ones you're alright," said Paris.

"One hundred per cent of the population is basically covered now but New Zealanders love to travel and so 50 per cent of the nation's geography doesn't have any connectivity at all. And this technology will mean you will have."

The tech will also provide a better connection for those out on the boat - with boaties promised to be able to access remote satellite networks as far out as 12 nautical miles.

One NZ hasn't announced pricing yet for its satellite services, although Paris reassured his plan to give as many Kiwis the chance to take advantage of the network. The working idea for the time being is to incorporate the function into existing mobile plans.

"But we haven't landed on that construct yet, we know how important it is to people to be able to use this tech when they need it," he said.

When the service does go live, One NZ has also agreed to provide every New Zealander access to a satellite connection for their phones, regardless of their telco company, to contact 111 in any emergency.

One NZ will be relieved to finally see Space X's satellite technology successfully launched after previously failed attempts by the space organisation to get the equipment into orbit.

Back in November, SpaceX’s huge Starship rocket blew up on its second test flight. It also blew up on its first test flight back in April.
