Pros
Verdict
Overall sentiment toward Mobile Monster is overwhelmingly positive, with the vast majority of consumers praising the business for offering competitive trade-in values and a fast, transparent process. Customers utilising the in-person CBD location particularly note the helpful customer service and swift transaction times. While a small subset of reviews highlights frustrations regarding delayed payments and revised device valuations, the core experience remains efficient and reliable for those buying or selling used tech.

Latest follow-ups
I sent in my iPhone for resale. They informed me it was locked and I needed to unlock for them to process it. I followed their instructions. They continued to say it was unlocked. I followed their instructions again. Again they told me it was still… Read more
locked. I call Apple customer who confirmed I had unlocked the phone and they could process it. They denied this and when I requested them to send the phone back to me as it looked like we couldn't resolve the issue they told me they had disposed of it. No warning, no email. They just threw out my perfectly good iPhone. What a waste of time and money. It feels like they stole from me, I feel scammed.
Follow-up · There was no disposal proof given to me at any time. They said they would reach out and follow up with me but I havent heard anything. An absolute scam, avoid at all costs.
I have been here several times. Junior is always nice and patient, helping me with my trade-ins. He’s professional, friendly, and really knows his stuff. Always gives honest advice and makes the whole process super smooth. Highly recommend coming here and asking for Junior if you want great service! Show details · 1
Follow-up · I am here every time to trade my old devices in, the receptionist knows the process well and walks me through the process with patience and let me know how long does it take, and what inspection the engineers gonna do to the device, and inform me how long does it take for the payment to go through. Once I have questions about the trade-ins, he… Read more

I was looking for a way to sell my old Samsung Galaxy phone, but I didn't really want to go through the hassle of selling it on Facebook Marketplace or Gumtree, etc. So, after a quick Google search, I came across this website (Mobile Monster), and after a bit of a look to make sure they were legit, I did a quick search to see what my model was… Read more · 1
currently worth. After I got the estimate, I was quite impressed with the offer, and I decided to go ahead with the sale.
Because I live in SA and this business is located in Melbourne, it meant that I'd need to send my phone to them. Apparently, I could have gotten a prepaid envelope sent out, but I just decided to pay the postage myself (with insurance) and send it directly to them without having any delays. After it was delivered, within only a few days of processing, I got paid for the full agreed amount that was on the original offer.
I really couldn't be happier; the whole process was simple and, most of all, hassle-free. I'd definitely recommend them to anyone wanting to sell their old phone.

Monster with a humble phone and modest hopes… and they obliterated my expectations with the force of a thousand pyrotechnic guitar solos. Their service wasn’t just fast — it moved at warp speed, as if delivered by a flaming Pegasus with a jet engine strapped to its wings.
From the moment I submitted my trade-in, I felt like I was being ushered backstage at a sold-out rock show, where customer service isn’t just service — it’s a VIP experience with golden lights, roaring crowds, and someone handing me a leather jacket embroidered with the words “Legendary Customer.”
Their communication? Crisper than the first chord of an opening anthem. Their offer? So fair, it could bring harmony to the universe. Their payment? Faster than a drum solo at the speed of light.
Mobile Monster didn’t just buy my phone. They elevated it to Valhalla. They made me feel like the hero of my own tour, a rock star striding off stage to the sound of chanting fans and confetti raining from the heavens.
5 out of 5 stars? Too small. 10 out of 5? Closer. ⚡ INFINITE GLORY, SUPREME CUSTOMER EXPERIENCE, LEGENDARY STATUS UNLOCKED.
If you’re even thinking about trading in your phone anywhere else, stop. Stand tall. Crank the amp to 11. And choose MOBILE MONSTER, the undisputed headliners of the trade-in world.

Misleading website, poor customer service, and a worthless price match guarantee. This has been one of the most frustrating customer experiences I’ve ever had. I submitted my phone based on the fair condition criteria listed on the company’s website, which clearly states that scratches and dents are acceptable under the “fair” category — only… Read more
cracked screens are considered “damaged.” My phone had some scratches, but no cracks. I was therefore expecting the advertised $550.
Instead, I was offered $275 — the price associated with partially damaged devices. After raising my concerns, the customer service team acknowledged there were no cracks but still failed to honour their own definition of "fair" condition. Eventually, they offered $300, which still falls significantly short of the originally stated amount.
To make matters worse, I presented a written offer from Mobile Monster for $460 and expected this company to match it as per their so-called price match guarantee. Rather than honouring that, they dismissed the clear evidence and gave their own speculative assessment of what Mobile Monster “would” offer — ignoring the actual email I provided.
Finally, after I declined their revised offer, they agreed to return my phone and said I would receive tracking details immediately. That was two days ago, and I’ve received no update or tracking information.
I rarely leave negative reviews, but this experience was unacceptable from start to finish. I would strongly caution others to avoid this company — their policies are misleading, and their customer service lacks integrity.

Negative reviews
I sold my phone with Mobile Monster online, and I had a very disappointing experience. I was initially offered $120 after accurately describing the condition of my phone. It then took almost two weeks just to receive the postage satchel. After they received my phone, I waited another four days before being told there was “screen damage,” despite… Read more
the only issue being what I considered to be an extremely small 2 mm long hairline scratch. My offer was then reduced to just $60.
By this point, the entire process had taken one day short of a full month. I accepted the lower offer because I didn’t want to wait even longer to have my phone returned. While I understand refurbished phone companies need to inspect devices, I don’t believe such a tiny scratch justified a 50% reduction in the quoted value, and the overall turnaround time was far too long.
Based on my experience, I wouldn’t use this service again.
Hi Max, Thank you for taking the time to share… Read more
Website is easy to use and the quoting system is also straightforward. I provided all details of my phone, including IMEI number which then allows them to fully identify the phone and it's value. Waited for the satchel to arrive, posted the phone in original box to them, only to be told the offer has been revised to $0 as the phone was older… Read more
than anticipated, but they offered to dispose of it for me. Very annoying! Then had to wait for it to eventually arrive back to my PO Box, after which I sold it on MarketPlace for double their original offer!
