Microsoft added the Lumia 535 to its range in November, as a larger alternative to its entry-level Lumia 530. In the UK, the 530's price has dropped to as little as £49.95 off-contract in recent months, but the 535 is becoming more affordable too.
But if you're looking for an unlocked 535 to use on a different carrier, Argos has got you covered. The retailer is currently offering the Lumia 535 for just £89.95 - SIM-free and unlocked - including free delivery.
Key specs of the Lumia 535 include:
- 5-inch IPS LCD with qHD (960x540px) resolution and Corning Gorilla Glass 3
- Quad-core 1.2GHz Qualcomm Snapdragon 200 processor
- 1GB RAM
- 8GB onboard storage (plus microSD support up to 128GB)
- 5MP rear camera with auto-focus and LED flash
- 5MP front-facing camera with fixed focus and wide-angle lens
- Accelerometer, proximity sensor and ambient light sensor
- Wi-Fi 802.11 b/g/n
- Bluetooth 4.0 LE
- 1905mAh battery
The device is sold with Windows Phone 8.1 Update pre-installed, along with the latest Lumia Denim release. Microsoft has said that it aims for "the majority" of its Lumia handsets to be updated to Windows 10 later this year.
