Website editor’s note: If you have a job or family responsibilities that mean that you cannot do without a mobile phone, this post is designed to help you avoid phones that are compatible with 5G – and may therefore expose you to 5G frequencies – in addition to those used in 4G, and perhaps 3G and 2G, too.  Please note that if you have to use a mobile phone to make or take calls, if you place your phone on a surface such as a table and use an airtube headset, this reduces your radiation exposure to your head and body .

A brief technical note:

In NZ 4G is proposed to be used as the “control layer” for 5G so any 5G compatible phone would also be a 4G compatible phone – and it would probably also be 3G compatible, too.

The frequencies used for 4G in NZ vary between cellular phone network providers and include 700MHz (used by Vodafone rural and Spark) to 700, 900 and 1800 MHz (2 Degrees). Spark also uses 1800 MHz for 4G.

In NZ, the first spectrum band that the industry wants to use for 5G is around 3.5 GHz (3500 MHz). Spark is also testing a band around 27 GHz and the government has indicated that it is willing to open up millimetre wave spectrum (30 GHz and higher) if needed.   The use of millimetre wave radiation in phones is controversial given that higher frequency MMW radiation has been used in weapons systems.

5G capable phones can therefore be expected to produce the frequencies used in 4G (and probably 3G as well) PLUS the higher frequencies that the industry wants to use in 5G systems.  (Confusingly the mobile industry often uses the term “millimetre wave” (mmWave) radiation when referring frequencies of 24 GHz and higher even though mmWave frequencies technically begin at 30 GHz.)

The production of mmWave radiation in a device that is held near the head is a concern due to eye damage in rats exposed to this sort of radiation in an experiment.

NZ Herald reports that 5G phones overheat – and other info about the Samsung Galaxy S10 5G

A 2019 story in the NZ Herald reported that Samsung’s Galaxy S10 5G was unreliable when temperatures reached 80 degrees Fahrenheit (27 degrees C).

The NZ Herald quoted someone who had experience with a new 5G phone:

“While running a download test or two, the phone would overheat and sever the 5G signal, leaving me with a 4G connection. I had to get creative chilling out my test phones. Yes, ice coolers.” [1]

Based on this it seems clear Samsung’s Galaxy S10 5G is a phone to avoid if you do not want a 5G capable phone.

According to this link it contains a Qualcomm Snapdragon 855 modem.

You can learn about the specifics of this modem here but suffice to say it is capable to producing the following frequencies:

  • 2.4 and 5 GHz Wi-Fi bands
  • 60 GHz Wi-Fi
  • “mmWave” radiation  as well as “Sub-6 GHz 5G”

The chipset for the phone is the Qualcomm® Snapdragon™ X50 Modem.

According to the link below the Qualcomm® Snapdragon™ X50 Modem can also produce 28 GHz “millimeter wave band” radiation.  (“Millimeter wave band” is in inverted commas because mmWave radiation starts at 30 GHz.)  

For more information see:

Based on this it seems very clear that Samsung’s Galaxy S10 5G is a phone to avoid if you do not want a 5G capable phone. (You’ll save a fair amount of money by not buying it, too, given that the cost is around $1000.)

Three Apple phones will reportedly be 5G capable in 2020

An article in The Verge indicated that three of Apples 2020 phones could be 5G capable citing as a source.

“Kuo says that he expects all three new iPhone models coming in 2020 to support both mmWave and Sub-6GHz spectrum to meet the requirements of the American market, but it is not clear if Apple will launch a 5G iPhone that only supports Sub-6GHz, which would allow for a lower price. He says Apple may not have enough development resources for such a project.”

It seems clear that if you do not want a 5G capable phone that could produce millimetre wave radiation as well as pulsed microwave radiation, avoid the 2020 Apple iPhone range.

Important note:

There may also be other brands of 5G capable phones coming onto the market…If you do not want a 5G capable phone please be a canny consumer and research any phone you are considering buying before you make a purchase.

Hardwired options are the healthiest options

Hardwired options are health healthiest options for you – and also beneficial for the environment because wireless data transfer is less energy efficient than hardwired systems. If you need information about safe hardwired internet connections via copper or fibre there is information on how to do this at the links below.

If you have only fibre to your home and would like a safe hardwired phone, there is information to help you here:

NB: You can find companies that do NOT plan to build 5G networks and offer internet connections and phone systems via copper and fibre at the the following links:
