ONEXOX Black B54DB plan

DescriptionPackage plan
Monthly feeRM54 RM49 (Limited time only)
Base data8GB (high speed)
Data from DB40G (10GB up to 4x a month)
HotspotUnlimited from data bucket
Voice CallsUnlimited to all networks
SMSs100 SMS for free

How is it works

B54DB plan comes with 8GB base data and 4 times of 10GB top up when the data balance reaches the threshold. The first 10GB top up will be high-speed data, whereas the second (10GB), third (10GB), and fourth (10GB) top up data speed will be at a 3Mbps speed.

10GB data will be auto top up each time your data counter falls under 2GB. The data top up will be credited to the BLACK data counter on the next calendar day. When the next bill cycle arrives, all data in the black data counter will be reverted to high speed.

When your bill cycle date arrived, you can carry forward the balance data and your data counter will be uplifted from the speed control. That means if you have 13GB (5GB carry forward + 8GB base data) high-speed data from the beginning of the new billing cycle, and you are still entitled to up to 4 times data top up during this billing cycle!

The downside

As of now, once the speed control is imposed, you will have to wait until the next billing cycle to enjoy high-speed data again. There’s no way the data will be reverted back to high-speed, even you purchase the Season Pass data.


Final verdict

ONEXOX has presented some of the best prepaid plans. They have been known to provide carrying forward unfinished data and their longest validity. However, for this specific B54DB plan, I would say it doesn’t really outshine its competitors.

Let’s take U Mobile GX50 for instance. U Mobile offers RM50 per month with unlimited internet data which is capped at 5Mbps. B54DB and GX50 are similar in terms of unlimited voice calls to all networks.

Honestly, I wouldn’t go for B54DB plan because of the capped speed. In my opinion, with 3Mbps speed cap, the plan should be cheaper. You can check out U Mobile P48, P38, or U28 for comparison.

But if the concern is the network coverage, then U Mobile may be at a disadvantage. Other than that, I can’t find any significant advantage.

That’s it. If you have anything to add, leave them in the comment below.
