The signal is picked up and repeated into the vehicle from the exterior 4G or 3G antenna on the vehicle. The cell phone reception is then amplified and sends it to the interior antenna, which broadcasts that signal to all cellular devices inside that vehicle.

UBBs vehicle mobile boosting kit includes a wireless booster, inside and outside antennas, and cables. It is designed to improve coverage, and can easily support multiple devices and cell phones.

  • No More Dropped Calls - Say goodbye to hard-to-hear and dropped calls. Using 3G signal boosting, which is the voice and data network in some parts New Zealand. Our booster kits can amplify strong signals outside the building or traces of an existing signal if you're in a remote area or on the road, and rebroadcast them to you. Modern signal boosters feature no noise or distortion to speak of.
  • Enhanced Emergency Safety - The most important reason to invest in a mobile signal booster? Being safe, and having the abilty to call family or 111 when an emergency may happen. Signal boosters help with safety by allowing consumers to call 111 in areas where cellular or wireless signals would otherwise be disruptive.

People who access the internet through their cell phone provider instead of wifi will see improvements with a signal booster. 77% of cell phone users face slow download speeds that prevent content from loading quickly.

Boosting mobile signal without approval is illegal in NZ. All cell phone signal boosters NZ must go through an approval process. We are lucky enough to be an approved seller and installer for Spark, 2Degrees and Vodafone. Not all units on the market are legal; we advise to only go through trusted companies for this.

There are many things that can cause cell phone signal to be poor, like distance from the cell tower, tree's, landscapes, hills etc. Even the number of devices in your area that are trying to connect to the same tower.

Yes! Vodafone ended the Sure Signal's life at the end of 2021. Our cell-fi signal boosters are the best alternative option, providing better 3G or 4G coverage though NZ's homes and businesses rural to urban!

The outside antenna that is installed on your building or vehicle and gets the signal from the closet cell tower. Then the booster unit inside amplifies the signal and sends it to the inside dome (signal extender) which is installed either on your roof and a mountable position inside the house no further than 15 meters away from the external 3G / 4G antenna for mobile, broadcasts the mobile signal from the chosen provider (Spark, Vodafone, 2degrees) out to your mobile phones or cellular devices!

Having better mobile signal will allow you to have crystal clear voice calls, downloads will be much faster! Text messages will come through faster, no more dropped calls, and wider coverage, not to mention the abilty to allow for your farm to stay connected in the smart farm revolution just to name a few!

One of the principal differences between 3G and 4G models is the speed at which they can download files from the internet. A typical 3G phone can connect to the internet at a maximum speed of up to 7Mbps, whereas a 4G phone can do so at theoretical maximum real-world speeds of 20-40Mbps. 3G, an abbreviation of ‘third generation’, 4G, an abbreviation of ‘fourth generation’. It is used to describe the previous generation of common standards in mobile telecommunication networks. Essentially, it meant that devices that were ‘3G ready’ could transfer data at a rate of at least 200 kilobytes per second, which is enough to stream a small video, or download an app. These standards were first implemented in the early 1980’s with 1G analog mobile technology. Now days 4G is best for mobile data and 3G is best for mobile calls and texts within NZ.

The Rural Connectivity Group (RCG), a combined venture between Spark, Vodafone and 2degrees. The the three main telecommunications providers in NZ are building more than 400 mobile cell towers to provide 4G wireless home broadband connectivity in rural areas. This is part of the second phase of the Rural Broadband Initiative (RBI2). With this comes new 4G-only mobile coverage in these areas which customers can use while on the go. The purpose of this fund is to connect rural addresses that had no internet options for home. Most of this new coverage is 4G-only, which allows customers to get set up with wireless broadband easily. Due to the new towers only providing 3G mobile signal, which means that since voice calls have historically requried the 3G network to make calls and texts, some mobile phones will not be able to make voice calls while connected to the new RCG towers. Most 4G capable phones however, can use data and SMS in these areas and will have service bars at the top of the screen. There is also 4G VoLTE, which voice over LTE, it is the next evolution of mobile calling that uses the 4G network for traditional voice calls instead of 3G, most telecommunication providers and ISP's allow for this option on their network in NZ.
