Hi, just to share my experience so that others can learn from it.

I use my UM prepaid just for its data, usually top up, say RM20 to keep the line active, use the free high speed internet for 20 days, and on Day 19 I will subscribe to UMI20 to use the 4G data for the next 30 days while my line becomes inactive. Just need the small amount of data for normal web browsing, email and what not.
I received these SMS, and from yesterday's SMS, I assume the auto renewal will be discon if I don't top up by yesterday.


Today I topped up money and to my surprise the UMI20 got auto renewed! Called CSO but none can help to reverse the charge. Was told my auto renew is supposed to be today, nevermind what the SMS said. SMS was to remind. Need to manually disable the auto renew. Now I rugi 20 days of 4G usage (the free 1GB data is more than enough for me per month).

Tu lah, regret not studying hard enough. Simple sms also can confuse me. Thank you.
