The Alcatel OT-903 is the cheapest Android smartphone in the UK and is currently available from Carphone Warehouse for £49.95 plus an extra compulsory £10 top-up.
One of the top-ups you can buy is on Virgin Media’s The Addict Tariff which promises to double up your first top-up, meaning you will get £30 when you top-up with a tenner. So if you top up with £62, you will get £186 in total.
You can sell that credit to Sellyourcredit.com for £111.60 - 60 per cent of the face value of the top up - payable via Paypal or BACS (note that you will get paid over two weeks).
Given that the total cost of the phone and the credit is just under £112, the adjusted cost of the phone on its own works out to be around 35p, although, caveat emptor, we haven’t tried it yet.
The phone has a small 2.8in touchscreen display with a 320 x 240 pixels display, a single core processor clocked at 650MHz, runs on Android 2.3 Gingerbread, has GPS, 150MB onboard storage, a 2-megapixel camera, a microSD card slot and weighs a mere 114g.
