The outage lasted for at least 4 hours.

MalaysianWireless would like to advise U Mobile customers to roam on Celcom 2G to stay connected with friends & family.

Using U Mobile, we experience some drop calls & poor voice quality roaming on Celcom. It did not happened the same when we used a Celcom 2G SIM.

We believe that the network roaming agreement between U Mobile & Celcom Axiata does not guarantee the quality of service for U Mobile customers.

This is probably the second major outage U Mobile has had so far and the 1st major network outage in the year 2012. It faced a similar network problem back in October where the outage lasted about 5 hours during business hours.

U Mobile CEO later said “Today we let you down and I would like to apologise for the service interruption you have experienced,”.

However no detailed explanation was given for the network failure. MalaysianWireless believes that the previous network outage was caused by an error in HLR (Home Location Register).

For that outage, U Mobile compensated customer with free unlimited SMS and 1.5GB of data.

[Update 1, Feb 2@1.10AM]- U Mobile Network was restored at 1.05AM. Voice, SMS & Data appeared to be working again. This means that the outage lasted for at least 4 hours. We will try to find out what caused the outage soon.
