Not again...SingTel seems to be forgotten the lessons learned (if they have the plan to learn from their mistakes in the first place). I've no idea what is wrong but my sources told that this is some thing to do with the packet core network (PS Core) which is supplied by Ericsson. If my memory serves me well this is not the first time they had this problem. Hopefully both SingTel & Ericsson works to overcome this problem to help SingTel and Customers :)
Customers of SingTel 3G mobile services have been experiencing problems with the network in parts of Singapore. Those affected since Tuesday night are mainly in the northern and western parts of Singapore.
