The PhoneMart Promise

Based on up to 100-points of inspection

We measure each battery's health and capacity against strict standards, and replace any that don't make the grade, so you get power you can rely on all day.
The display is switched on and looked over closely for any blemishes, so there are no marks, dust spots or discolouration to spoil the view.
Where a charger is included, the cord and connectors are checked for wear, and the plug is confirmed to fit sockets.
Before it ships, every device gets a thorough professional clean and polish so it feels fresh in your hands.
Every lens is put to work, so we can confirm sharp photos, smooth video and reliable performance on video calls.
A full factory reset wipes the device clean, securely erasing all previous data and restoring the original settings.
We confirm the network status up front, so you know exactly whether the device is locked or unlocked before it arrives.
Cards are inserted to make sure the device reads SIM and memory cards correctly, and that every tray and slot works smoothly.
Each button is pressed to check it responds straight away and does exactly what it should, from volume to lock to power.
If any parts are fitted during refurbishment, they are tested for compatibility and held to the same standards as the originals.
We run the IMEI to confirm it is clean and never blacklisted, and that the device details match the manufacturer's records.
The moisture indicator inside the device is inspected to rule out any history of water or liquid damage.
Every port, including the headphone, USB and Ethernet connections, is checked to make sure it connects and works reliably.
Face and fingerprint unlock, along with any voice recognition, are tested to make sure they work quickly and accurately.
Positioning is checked for accurate GPS, so maps and location apps behave exactly as they should.
External sensors, such as proximity, brightness, laser measurement and heart rate, are checked for precise and responsive readings.
Screws, casing, frames and other mechanical parts are examined to confirm they are original or quality replacements, and any replacement has to match or beat industry standards.
We confirm that Wi-Fi and Bluetooth connect quickly and hold a stable signal.
Speakers and microphones are inspected and fine tuned so audio records and plays back clearly.
The flash and every indicator light are tested to confirm they light up and work correctly.
Any features that are specific to your device are checked against the same standards, so nothing gets missed.

I bought this as a gift for my mum. She finds it easy to use and navigate. I would definitely recommend PhoneMart for tech purchases in the future.

This is the second phone I have bought from PhoneMart and I am very impressed with the quality of both. No visible marks and both work perfectly. I will be back for more tech supplies.

I bought two iPhone XR phones and a OnePlus 8. All arrived in excellent condition and worked properly. The only issue is with the OnePlus 8: the Google microphone button does not pick up any sound, although the mic works for everything else.

The phone was in better condition than described and arrived several days early. There was a small extra charge that wasn't mentioned. A couple of minor software bugs appeared but they are no big deal. The operating system was updated. I got this phone to use while my main phone with a swollen battery is being repaired. It is working well and the apps transferred successfully.

I bought this as a first phone for my 11 year old. Although it was listed in fair condition, I expected some scratches or dents, but it arrived without a single mark. After three weeks, everything works fine. Great value for the price.

I got this as a first phone for an 11 year old. Since it was in fair condition I expected it to look worn, but apart from a chip on the corner (maybe the screen was replaced) it was spotless. It's been three weeks and there are no problems.

The phone looks almost brand new and I'm happy with it. I'm not sure the battery is truly like new, but I suppose that's to be expected.
