Katherine mobile phone users will need Optus phone plans to take advantage of planned mobile blackspot fixes across the NT.
A majority of local phone users are believed to have Telstra enabled phones in the region.
A new mobile tower being funded by the Federal Government at (Leliyn) Edith Falls was seen as a potential lifesaver, given recent search efforts in the area.
Tourists had also welcomed the arrival of the blackspot fix to the popular campsite and swimming hole.
But you will need to have Optus.
People with any other phone plan, can use service from this tower to make a call to Triple 0, regardless of their carrier.
The partnership with Optus became clearer when the Federal Government switched on blackspot fixes for Wangi Falls and Florence Falls at Litchfield today.
The improved service is thanks to the Government's $380 million Mobile Black Spot Program that is removing mobile black spots across the NT.
The list of NT blackspots to be removed includes:
Arltunga Vc, Chambers Pillar, Devils Marbles, Dunmura Wayside Inn, Edith Falls, Ellery Creek Big Hole, Larrimah, Palm Valley, Shady Camp, Tobermorey, Trephina Gorge East, Trephina Gorge West.
The new base stations are being delivered by the Government in conjunction with Optus.
An Optus spokeswoman confirmed: "Only Optus customers can access these, although if making an emergency call to 000 then it can be accessed by anyone regardless of their carrier."
Optus was awarded funding for 25 sites across the NT as part of rounds two and four of the Government's Mobile Black Spot Program.
The two-new satellite small cells located at Wangi Falls and Florence Falls have been co-funded by Optus and the Federal Government to support tourism at the popular Litchfield National Park destinations.
The new cells will allow visitors to the falls with the ability to make and receive calls and most importantly, will provide coverage for all visitors to make calls to emergency services regardless of their network carrier.
An additional site will also be delivered close to the Ranger Station in the western part of the Park later this year providing coverage to Walker Creek using 4G and 3G technology.
"With eight new Mobile Black Spot sites already live in the Northern Territory these two sites will play an important role in addressing the need for mobile coverage across the Territory. We worked closely with the Northern Territory Tourism Board and Parks NT to identify the best location for these sites based on visitor numbers and need and it's great to see our customers already benefiting from them," Optus said.
Satellite small cells provide a flexible alternative to a traditional mobile tower, using satellite connectivity and backhaul to deliver mobile coverage to a concentrated local area.
