With the low prices for 5G phones, it is vital to know that if you buy a grey market phone, it will likely not work on the Australian 5G network. It may not even work on the 4G network. The same applies to overseas purchases as well.
Here is a summary of the main issues relating to grey market smartphones and these are explained in-depth further on.
- It will generally not work on Australian 5G networks (it may connect to 4G). Australian Telcos require specific commands and metadata to make or receive phone 5G calls.
- It may not hand off to other towers, causing signal loss when moving.
- There is no manufacturer’s Australian warranty—you rely on the online vendor, and most require you to ship it back to China at your cost.
- Have different modem specifications, especially for Wi-Fi 6, 6E and 7 phones. Some frequencies used in other countries are illegal to use here (ACMA only allocates portions of the spectrum).
- No over-the-air (firmware) updates. These are country-specific and are often tied to the IMEI number.
- Won’t make a 000 emergency call (set for 911 or other emergency network)
- Won’t receive SMS, MMS, etc. (They may receive the newer RCS text and multimedia).
- Chargers may not be RCM C-Tick approved, voiding fire insurance.
- And the big issue – a huge upswing in fake phones that are hard to tell from a real one.
Samsung’s take
Samsung sells more phones than any other manufacturer. It sees numerous issues of grey market and fake phones (read later) and has published an official position on this – Samsung Made for Australia.
Note that its approved retailers include Telstra, Optus, Vodafone, JB Hi-Fi, Harvey Norman, The Good Guys, Amazon (Samsung Official Store only), Officeworks, Bing Lee, Woolworths, David Jones, Myer, Costco, BIG W, Target, Radio Rentals, RT Edwards, Retravision, Betta, and Australia Post.
You will note that this excludes all grey-market sellers below who will swear on their mother’s grave that they sell fully guaranteed Australian stock. Total bovine excrement!
Other brands – (not all models are sold at all approved resellers).
Motorola-approved resellers include Harvey Norman (and its sub-brands), JB Hi-Fi, Good Guys, Officeworks, Big W, and usually the three telcos. It also sells online via Lenovo’s e-commerce site.
OPPO sells online and via JB Hi-Fi, Good Guys, Woolworths, Big W, Coles, Officeworks, Bunnings, and its Amazon official store (not via the Marketplace), all major telcos and Konec Mobile (OPPO affiliated).
Apple has a website locator for genuine products.
Google PIxel has Harvey Norman (and its sub-brands), JB Hi-Fi, Good Guys, Officeworks, Qantas Marketplace, and the three telcos.
Some manufacturers use MyDeal and Catch.com.au for runout stock. There may be some business/enterprise solutions suppliers.
What is the grey market?
It is anything other than approved retailers. Grey market is almost any merchant marketplace from Kogan (includes Dick Smith, Matt Blatt, Mighty Ape), Amazon, eBay, as well as lots of smaller stores like:
Allphones All PC Supplies Australian Warehouse | BecexTech Australia Best Mobile Phone Australia Buy Mobile Australia | CeX AU Cash Converters Cooper Connect | Design Info |
Etoren Etsy Emporium | “F” | Gadetward-AU Green Gadgets | “H” |
i-tech.com.au | Jack Deal JC Browns Market | “K” | “L” |
MobileCity/ MobileCiti/Mobiciti My Mobile | “N” | Onestop digital OZ Mobiles | Playthek Privacy Portal Phonebot |
“Q” | Rebello (and its marketplace) Realry | Skyphonez Snaffle Spectronic Australia | 3 Brothers Mobiles Techinn Tech Cart TechBuy Telechoice TobyDeals AU |
“U” | “V” | Wise Market Australia Zylax | 100’s more (many are a guise for the same companies) |
Readers have asked specifically about Mobileciti (and all variations). Let’s just say that it may have some Australian stock, but it also has a huge grey market range. Samsung, Apple, and Motorola have all tried to have it remove their grey market products from its website.
That does not mean that some of the above may have some genuine Australian brands/models, but how do you know until you buy and try to get a refund? Good luck there!
If you find a grey marketer, please let us know, and we will add it to the list. If your company is listed as grey market and it is not, please get your manufacturer to email [email protected] with verification, and we will immediately remove the listing.
Don’t believe grey-marketers’ claims that their phones are Australian-certified, and never believe that an ‘International model’ will work here.
Problems with grey market phones
Telco bands
In the old 3G days grey market was not an issue as this was a global network. But as 3G is phasing out soon, you won’t be able to fall back from 4/5G to that to make a voice call.
4G is an issue as some bands are uniquely Australian and not supported by grey market phones. In particular, lower bands 28 (700Mhz), 5 (850Mhz), and 8 (900Mhz) are best for in-building and distance coverage. Grey market typically only get bands 3 (1800Mhz), 1 (2100Mhz), 7 (2600Mhz) and 40 (2300Mhz). These are only good for the city and suburbs – short distance line-of-sight to the tower. If you use Optus, its Band 42 (3500Mhz) becomes more important as a 4G+ data band.
5G is critical as the IMEI of all genuine Australian phones is registered with the Telcos. Simply put, you can only activate Australian 5G handsets in Australia first, and then they can roam overseas. That means grey market 5G may turn out to be nothing more than an expensive 4G phone.
Some brands, like Samsung, also region-lock genuine Australian phones. They are trying to protect your interests from unscrupulous grey market importers as phones from other countries are often stolen, refurbs, second-hand, demos, seconds, or even counterfeit.
Mandatory Australian Telco bands (Whirlpool list)
- 3G Telstra (5), Optus (1, 8) and Vodafone (8)
- 4G Telstra (1, 3, 7, 8, 28), Optus (1, 3, 7, 28, 40, 42) and Vodafone (1, 3, 5, 7)
- 5G Sub-6Ghz n78
- 5G Low band, n5 (Telstra), n28 (Vodafone), n40 (Optus)
- mmWave (not in wide use) n257, n258 and possibly n261
OS upgrades and security patches – none
You may not get operating system upgrades or regular security patches. That means they are more vulnerable to malware and other issues.
Warranty – none
Grey market phones do not have an Australian Consumer Law warranty, where the retailer and the manufacturer must provide the warranty.
The majority make it very hard to claim a warranty saying that it is a user error or physical damage is not covered. You often have to post the item back to the company, usually at an international address. That can take weeks, and forget any hope of a refund – all sales are final.
How to identify a grey market phone
The majority of these
- have a non-genuine international round/flat pin charger or a non-genuine generic Australia charger or adapter
- are shrink-wrapped – no box (so you cannot check the original carton for the region or LTE bands printed on it)
- do not support all 4G (or 5G) bands used here
- do not support Telstra/Optus or Vodafone VoLTE (Voice-over-LTE)
- won’t make a 000-emergency call without a SIM
- may not hand off properly from one tower to another (billing issues and dropouts)
- won’t accept over-the-air firmware updates – ever!
- Do not have RCM C-Tick under settings and regulatory lables.
So, you end up with 4G for most use.


Fake phones
Benchmarking platform AnTuTu has revealed that from March 2020 to February 2021, about 5% of 3.15 million phones tested were fake. Samsung led the way with 34%, Apple 13%, OPPO 5% and vivo 3%.

Since then, it has become an epidemic. OzBargain reported that 9 out of 10 Samsung Galaxy S23 Ultras sold on marketplaces were fake! Read more at XDA.
And the big one – RCM C-Tick
If you go to Settings, About Phone, Regulatory Information (or similar), you must see the RCM C-Tick mark. It must also be on the charger and the box.

Cybershack’s view – don’t do it
We all love a bargain, and we have been guilty of eyeing off these apparent grey market bargains without knowing the downsides. This guide is not to scare you but to help you spot a grey market or even a counterfeit phone.

Today the Motorola web was listing Mobileciti as one their partners (along with JBHifi, Officeworks, Good Guys, Harvey Norman, Big W and Vodafone). I think a customer who bought a grey import from Mobileciti would have a strong claim against Motorola if was returned under warranty.
Ray Shaw
Let’s just say that we do not list MobileCity for any brand due to the past incidence of grey market imports. Customers must check that the phone has an R-NZ C-Tick – its not about Motorola but representations of the company you bought it from.

As an aged person with some IT knowledge reading all that jargon l am more confused than ever!

Put simply – If it is not Australian certified from an approved Australian retailer it will have issues. I will revisit the article and see if we cannot clarify it more.

They are lovely phones but I can only look at them

Kogan/Dick Smith and Catch (Wesfarmers, which also owns Officeworks, which is in your “legitimate” list) are Australian owned and registered businesses. They are not “grey market” suppliers as you suggest. The T&C’s of both companies state that the ACL applies to all products sold on their respective sites.
Ray Shaw
Kogan/DickSmith/MightyApe et al., are not approved retailers for the majority of phone brands. Its marketplace is chock full of grey market phones. Catch is not an approved retailer either. However Catch (like MyDeal) is being used by manufacturers to move excess or superseded Samsung, Apple, OPPO and Google inventory as well as refurbished products. Many of its deals are from its marketplace vendors and many of these are grey-market. Catch is probably safer to buy from but make no mistake ACL only applies to genuine phones certified for Australia and sold my approved retailers.

The statement:
“5G is critical as the IMEI of all genuine Australian phones is registered with the Telcos. Simply put, you can only activate Australian 5G handsets in Australia first, and then they can roam overseas. That means grey market 5G may turn out to be nothing more than an expensive 3G phone.”
Is simply not true. There is no registrar of “genuine” 5G device IMEIs. Any 5G device can access 5G regardless of where it was sourced from as long as it supports the appropriate bands and you have a 5G enabled service from your carrier. Yes there can be other issues in terms of stability/bugs etc. with “non approved” devices but they should still work in theory.
Ray Shaw
We can only repeat what several authoritative sources have told us. In essence that the three main Telcos (not a registrar) are given a list of all approved certified 5G IMEI’s and they must be activated (used in Australia first). I will attempt to get an update. So I guess neither of us can state it is simply not true or is true and your comment will be investigated thoroughly.

Hmm things were very different with the roll out of 4g, Retailers were slow to roll out decent 4g phones here with the only initial choices being a few Samsungs & LGs all on plans, but the 2013 Google Nexus 5 &(worldwide version) & Motorola Moto X (AT&T custom walnut import) were future proofed with bands 1, 8, 40 & 42 a year before they rolled out here….
There was once a market for Greys as they could be an exclusive alternative & some models catered to just that (pure version anyone?) So it’s no surprise if Telcos & manufacturers are onto this with baked in safeguards by now.
Ray Shaw
In one way, it protects those companies that invest in Australia and pay the license fees which means Australian Consumer Law warranty. In another way, it should be a free market. I was gobsmacked to learn that 5G EMEI numbers for Australia must be activated here first (before international roaming). I have just read a further article on the https://cybershack.com.au/news/oneplus-smartphones-not-approved-for-sale-in-australia-warning/ that states these are region locked to ensure you buy from OnePlus and not a grey market seller.
