M1 Limited (previously known as MobileOne) is a full-service telecommunications company in Singapore. Launched in April 1997, it was Singapore's second mobile operator after SingTel.
As at end-February 2013, major shareholders include Keppel Telecoms (19.55%), SPH Multimedia (13.60%), and Axiata Investments (29.01%). The remaining shares are owned by institutional and public investors.
M1 is one of the three major mobile-communications providers in Singapore. It offers a suite of mobile voice- and data-communication services over its 2G/3G/3.5G/4G network, including international-call services to both mobile- and fixed-line customers. These include SMS, MMS, WAP, GPRS, 3G, 3.5G and was the first Singapore operator to launch a nationwide 4G LTE. It also offers prepaid mobile services, such as prepaid data plans, under its M Card brand. It is currently the only operator 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.

In April, M1 announced that it would spend up to $85 million to "modernise its mobile networks, as well as to deploy a nationwide 3G radio network on the 900 MHz frequency band". This is expected to be completed by 1Q2014.
