Buying a Mobile Phone Safely: New, Refurbished or Second Hand

01

New devices

Buying new gives you the most certainty: no prior usage history, a manufacturer warranty, and the latest software support from day one. The main consideration is cost, since new devices typically carry the highest price point of the three options. If buying new, it is still worth keeping proof of purchase and registering the warranty where applicable, in case you need support later.

02

Refurbished devices

Refurbished phones have typically been used before, then inspected, repaired where necessary and restored to a working standard by a seller or a formal refurbishment programme. This can offer a middle ground between cost and reliability, since refurbished devices are usually tested before resale and may come with a limited warranty.

When considering a refurbished device, it helps to ask what grading system was used to describe its condition, whether the battery health was tested, and what warranty or return period is offered if a fault appears shortly after purchase.

03

Second hand devices from private sellers

Buying directly from another individual, whether through a classifieds site or in person, can offer the lowest price, but carries the most risk since there is typically no formal warranty or inspection process involved. A few checks can help reduce that risk considerably.

IMEI check

Every mobile phone has a unique IMEI number, usually found in the phone's settings menu or printed on the box and under the battery on older models. Checking this number can help confirm whether a device has been reported lost or stolen, and whether it is blacklisted on any network. Dialling a standard code on most phones will display the IMEI if you need to check it before or during a sale.

Network lock status

Some phones are locked to a specific network, meaning they will only accept a SIM card from that network unless unlocked. If you plan to use a different network, confirm the lock status before buying, since unlocking a device after purchase is not always straightforward or guaranteed to work.

Physical and functional inspection

• Check the screen for cracks, dead pixels or discolouration under different lighting.
• Test all buttons, the charging port and any biometric sensors such as fingerprint or face unlock.
• Make a test call and check both the speaker and microphone work clearly.
• Check battery health if the phone's settings allow you to view it, since battery degradation is common in older devices.
• Confirm the phone is not locked to a previous owner's account in a way that would prevent you from setting it up as new.

Meeting and paying safely

When buying from a private seller, meeting in a safe, public location and avoiding full upfront payment before inspecting the device in person reduces the risk of fraud. Where possible, test the phone fully before completing payment, rather than relying on photos or a seller's description alone.

04

After the purchase

Once you own the device, whether new, refurbished or second hand, back up important data regularly, keep the operating system updated, and set up a screen lock. These steps protect your information regardless of how the phone was acquired, and are especially important for second hand devices where the prior usage history is less certain.
