Months ago,U Mobile started to share with Maxis for its infrastructure in order to expand its 3G network to nationwide.Since then,the 3G coverage on U Mobile in West Malaysia came to be good.Well,recently it started the expansion in East Malaysia and the major cities and towns there had 3G service already.
The areas having 3G service are Kuching,Sibu,Bintulu,Miri.Labuan,Kota Kinabalu,Sandakan and Tawau.You can check the details of it coverage here
U Mobile’s 3G network supports up to 42Mbps DC-HSPA+ .The collaboration with Maxis will let U Mobile expand faster and save more capital.I believe it will also benefit on deploying 4G LTE network which U Mobile maybe will start the service in the year.
Anyway,as a user of U Mobile,I feel some service downgrade in terms of speed and downtime.I hope they could improve the service continuously with the growth of the number of users and don’t let me down.
