Analysis of plans

Like the previous price bracket, the most eye-catching data plan is TPG’s 80GB for $18 plan, the most generous among this bracket despite not being the most expensive.

Another contender is Giga!'s Top Pick plan, with data rollover for two cycles. While it can't outright match TPG's plan in terms of raw data, rollover means you can carry over unspent data allotment to the next month(s). The 2,000 minutes of talk time and reliance on StarHub's more mature network doesn't hurt either, though you'd have to consider if you'd actually end up with enough data at the end of each month to justify the extra S$6.

If you prefer a more balanced offering that's also cheaper, MyRepublic’s Core Plan grants you 50GB unthrottled data and 500 SMSes for S$20 a month.

As for Changi Mobile's offerings, like the previous Flexi Value plan, their Flexi Best plan has good value if you manage to catch the early bird price, as it's comparable to VIVIFI's 50GB Binge plan, with a 10GB reduction in data for S$3 less. Otherwise, its usual price of S$25/month doesn't stack up to Giga's aforementioned Top Pick plan, especially as Changi Mobile's data rollover only lasts until the end of the year.

As for their Flexi Pro plan, even at the S$25/month early bird price, it only matches Giga's Top Pick plan in data, and falls short on talktime and SMSes. For its usual price of S$35/month after 31st December, it can't compete with other high-end plans at all, though we'll save those offerings for later in the comparison.

Similarly, Zero1 also offers you 50GB of data for less than S$20 a month, but be prepared to pony up the additional registration fee. It's worth noting that Zero1 also featured a 30u plan for S$24.95 while this list was being compiled, but at the time of writing it has disappeared off their platform.

M1's Bespoke SIM-only plan gives you the option to customise the amount of data and talk time in your plan - but the price goes up if you add more allotment to it. It's also rather expensive, with the absolute base plan costing almost S$16 and only giving you 5GB of data and 100 mins of talk time. 

Our say

• For best value and most data ► TPG's 80GB plan at S$18
   
• For abundant talk time, SMS and data  ► Giga! Top Pick plan at $25
   
• For a good balance of data, talk time and SMS ► MyRepublic's Core plan or Zero1's 50u Plan at S$20
