These include SMS, MMS, WAP, GPRS, 3G, 3.5G and 4G and was the first Singapore operator to launch a nationwide 4G LTE and 4G LTE-A network. It also offers prepaid mobile services, such as prepaid data plans, under its M Card brand. It is one of the operators in Singapore to offer a prepaid 4G service. M1 offered GSM services to its customers upon its entry into the mobile-communications market in 1997. In 1998, M1 introduced CDMA as the second mobile network in Singapore. However, customers on the CDMA network were migrated onto its GSM network in 2001. This was due to the CDMA network spectrum being earmarked for 3G service developments. The company also launched Singapore's first mobile broadband services in 2006, named M1 Broadband, and introduced fixed broadband services in 2008. In 2010, it launched Singapore's first fibre broadband service. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「M1 Limited」の詳細全文を読む スポンサード リンク
