Last week, i went to Singapore one day and used my U mobile postpaid international roaming for GPS usage and messaging app(They actually have a 50MB free of roaming data). However, after i came back to Msia, my phone service got barred, and i received a bill of payment RM634 need to pay for the exceeding roaming data. I called to the customer service tell them it supposed to have a credit limit of RM150, but they told me i was at the different country using different operator. So, my question is can i ignore this bill ? Because i am going to start working in Singapore next week, and i'm no longer need this postpaid line anymore. I heard they would blacklisted me for applying the umobile service only.

Bodo, dah guna tu bayar la. Yang you pandai pandai guna roaming tu apahal? You no pay they CTOS you.

U will be blacklisted on ALL telco....

Next time go roaming.. be smart abit lah... like Maxis have deal with Singtel unlimited data for RM38....

GPS do not need data roaming. Learn to offline mapping systems like HERE, Sygic, etc..

All telco work like that. The credit limit only for local calls / data only.

that's why I have a second phone handy just for travelling overseas which I turn it into a hotspot.
