As a more recent example the Apple iPhone 5 and iPhone 4S support quad-band GSM at 850/900/1,800/1,900 MHz, quad-band UMTS/HSDPA/HSUPA at 850/900/1,900/2,100 MHz, and dual-band CDMA EV-DO Rev. A at 800/1,900 MHz, for a total of 'six' different frequencies (though at most four in a single mode).

Overall, where the 450 MHz NMT band exists, it either still runs NMT, or its been replaced by CDMA.

Its competitors, Turkcell and Vodafone Turkey, have both been founded in 1994 and use the GSM 900 frequency range while Avea uses the GSM 1800 range.
