I wish to disabled too while I travel, I prefer charge per use on sms/voice as I will not be using data while travel as I will buy the local SIM and using free wifi.. How Can I opt out on the auto activation? Any advise?
As I will be travel few days ant not heavy data user, plus WorldPass is not 24 hours from activation but expired by 12:00am

from maxis website: "any calls (received or made), any SMS sent, any data used (via webpages, apps, and all other platforms) will automatically kick start your MaxisONE World pass."

"The pass is valid till midnight of the visiting country’s capital city time. E.g. If you are in Philippines, the pass expires at 12 midnight Manila time."

Imagine you get an urgent call at 11:50pm that cost you RM11, and Maxis will auto activate your World Pass, by 11:59:59pm, it expired, and charge you RM38..

This is the reply I get PMed by Maxis which I do not mind to shared

We can assist to whitelist your name from being under this Maxis One World pass, which means all your call will be based on pay per use and you can only hook to NON preferred network and you will be not able to purchase any promotional data pass. If you wish to be under the list, you may provide us with the details below:

Name:
NRIC:
Mobile Number:

This is the reply I get when I email maxis customer service:

Unfortunately, we are unable to deactivate the Maxis One World roaming services as it is activated automatically. Your feedback is highly appreciated and will be highlighted to the respective management for future enhancements.

We do not have any agreement with Starhub as such, even if you would to choose the services, you will not be able to hook with the network.
