Analysis of plans

Zero1's 80u Plan is certainly attractive. It's well-rounded in talk time, SMSes and has the second-highest amount of data in this price category. If you're eligible for the promotional price, it's also a great deal as well.

Otherwise, the other options in this bracket come relatively close in value. For example, 10¢ more can give you 200 mins and 200 SMSes more in MyRepublic's Pro Plan, along with a slightly reduced amount of high-speed data. Of course, there's the option of CMLink's travel-focused 60GB Plan as well.

VIVIFI's Share plan seems convoluted at first glance. What it incentivises is plan sharing, where a single SIM costs S$31.90/month, and each SIM afterwards cost S$5.35 to add - making it an ideal plan if you're splitting among other users. For example, assuming you're planning to split the cost evenly between each user, two SIMs can get 60GB, 300 mins and 50 SMSes each for S$18.63 per pax. Talk time and SMSes are a bit constricted in this case, but in terms of data, where S$15-25 plans mostly offer anywhere between 10-50GB, it's a competitive choice.

Where VIVIFI's plan shines is perhaps when you need to provision a dedicated phone number per person in the family, but they are mostly staying at home and thus require very little mobile data. So the more family members you add, the cheaper it gets to own a phone number per person. Keep in mind, though, that VIVIFI's Share plan data is only 120GB for the first 12 months. It goes down to 40GB afterwards (along with a price cut to S$29.90).

That said, the Giga! and TPG plans from the S$15-S$25 range on the previous page are comparable, if not better than most options offered here. It's worth exploring if you really need to pay S$5-S$10 more every month, brand biases and network preferences aside.


Our say

  • For a balanced, well-rounded plan ► Zero1's 80u Plan or MyRepublic's Pro Plan at S$30
  • For generous talk time and SMS  ► Take Giga!'s Top Pick plan (listed on the previous page) for 2,000 minutes and SMS at just S$25
  • For the most amount of mobile data ► Take MyRepublic's Core Plan (listed on the previous page) and add-on 50GB of mobile data for a grand total of 100GB all for S$29.90
  • A travel-focused plan to share data between SG, CN and HK ► CMLink's 60GB plan at S$30
  • For the lowest cost per phone line per person in a large family ► VIVIFI's Share plan at $31.90 
    (but beware of limited data, talk time and SMS unless you're buying add-ons)
