Harri Holkeri making the 1st GSM call


Its been 20 years since the first call was made using GSM technology on a commercial network back on 1st July, 1991 with a NMT phone (first generation of phones). Today we celebrate the 20th year of Global Serivice of Mobile Communications (GSM).

If you didnt know, the world’s first commercial GSM call was made in Helsinki, Finland on the Radiolinja’s network when prime minister Harri Holkeri called deputy mayor of Tampere Kaarina Suonio (see photo of the first gsm caller 1991).
