Malaysian mobile operators Celcom Axiata and U Mobile have extended an agreement on domestic roaming for a further three years, Bernama reports. Under the updated contract between the two companies U Mobile customers will continue to be able to operate over Celcom’s 2G network in those areas where the U Mobile 3G network is not present. Further, it is understood that as part of the revised deal, at an undisclosed time later this year U Mobile subscribers will also be able to access data services, such as mobile internet and multimedia messaging (MMS), over the Celcom network.
