Launched May 1992
Early mobile phones were terrible things. Not only were they big and clunky, but the old analogue networks that they ran on had terrible call quality, poor reliability and were very insecure. These early technologies such as AMPS, TACS and NMT became retrospectively known as “1G” – these days often forgotten and unloved.
By 1992 these 1G networks had been around for a decade or so and their weaknesses were becoming obvious. The market was ripe for something better, and in 1992 the world’s first 2G GSM networks came online. These digital networks had better call quality, security and required a smaller slice of the radio spectrum, and the first certified GSM phone to be available was the Orbitel TPU 901.

A bulky device even by the standards of the time, the 901 had a handset connected to the base station via a curly cord and it weighed a whopping 2.1 kilos. It wasn’t a big seller – smaller and cheaper GSM phones were not far off – but the Orbitel TPU 901 does have the distinction of receiving the world’s first SMS text message with the words “Merry Christmas” sent in December the same year.
Orbitel was a British-based joint venture between Racal (who owned Vodafone) and Plessey which eventually ended up in the hands of Ericsson and effectively vanished in the noughties. Today the TPU 901 (and the car-mounted TPU 900) should still work on 900MHz GSM networks, if you ever managed to get your hands on one.

Of course, the 901 was the first of many GSM phones on the market, more memorably the Motorola International 3200 launched later in 1992 with a memorable brick-like design that summed up the era perfectly. About a million others followed, but the Orbitel TPU 901 – largely forgotten today – was the very first.
