Yes, no need to pay anything once you have purchased earlier.

Good thing about XOX, it's perfect for low usage users.

My friend who's working in SG and only comes back to Malaysia once a month or twice max. I just helped her to MNP from Hotlink to XOX to enjoy 28 months free validity. She needs to maintain no. for Malaysia banking TAC and use it when she's back in Malaysia.

In additional, she also bought 10GB data for RM 50 with free 10GB data (needs to utilize within 30 days after activation). She can slowly use the 10GB without worrying it to expire, can redeem bit by bit. Since she only needs it for WhatsApp and light FB when she comes back, I recommend her to subscribe to 500MB per month, at least it can last her 20 months. Then just reload and buy during Happy Hour.

She's happy with XOX.

That's correct. My OneXOX card is a backup and I subscribe whenever I need data from it. Just remember to cancel the auto-renewal.

Can stop auto-renew once the FAT500 is activated, so you won't forget later. With OneXOX, you can still continue to use until the end of the 30 days.
