Zero1 Referral Code (2026): Get S$1-S$2 Off Your Bill When You Sign Up

Use Zero1 referral code Z18QNTY1 when signing up to get S$1-S$2 off your second bill, depending on the plan you choose.

Why Zero1 (And Why Maybe Not)

Before you use this code, it’s worth knowing honestly where Zero1 does and doesn’t fit.

Why Zero1:

• Runs on Singtel’s network, which in my experience has been the most consistently reliable coverage wherever I go
• No contract, so you can leave anytime without penalty
• Movemo Vibe is priced as a 4G plan, and per Zero1’s terms and conditions is supposed to come with 5G+ at $12/month regardless of port-in source — though Zero1’s own T&Cs confirm this is a limited-time promotion, so check it’s still live before signing up (more on this below)
• Has an actual physical service centre (Tai Seng) for anyone who wants face-to-face support — a genuine differentiator against Gomo and Vivifi, though ZYM also has one

Why maybe not Zero1:

• Promotion mechanics can be genuinely confusing to follow — which plans get 5G+, under what conditions, and for how long isn’t always straightforward
• I’ve come across conflicting details between Zero1’s own website/T&Cs and their ad campaigns on the same plan, which makes it harder to know exactly what you’re signing up for without double-checking multiple sources
• Mail delivery, if you choose it, can take a few days longer than the standard estimate — courier or self-collection are faster if timing matters to you

If the pros outweigh the cons for your situation, here’s how to actually use the code.

Which Zero1 Plan Should You Pick?

I go through Zero1’s full plan lineup, including a clever conditional 5G+ mechanic on one of their plans, in my full porting experience and 5G plan breakdown. Here’s my actual recommendation:

• Movemo Vibe ($12/month), if it comes with 5G+ — per Zero1’s terms and conditions: “This includes 5G/5G+ access for all eligible new subscribers who sign up for a new mobile number or port in an existing number, from 01 Aug 2026 onwards.” Zero1’s own T&Cs also confirm this is a limited-time promotion, not a permanent plan feature — so check whether it’s still live when you sign up. If it is, this is genuinely my top pick at $12/month for 700GB with 5G+. If it’s ended, go with Streamo Freedom below instead. I go through this in more detail in my full breakdown.
• Otherwise, Streamo Freedom ($15/month) — this one’s unambiguous. It carries “(5G+)” directly in its name and comes with more roaming inclusions (60GB worldwide, 1TB Malaysia/Indonesia/Thailand) on top. If you’d rather not deal with any uncertainty over Movemo Vibe’s 5G+ status, this is the safer pick.
• Movemo Dash ($20/month) — Zero1’s top-tier plan, for power users who want the most local data (800GB) and roaming (45GB RoamAP).

Worth knowing as general context: looking across current standard 5G+ offerings from MVNOs on Singtel’s network, $15/month is roughly where the genuine, no-strings-attached floor sits — Zero1’s Streamo Freedom, ZYM’s Roam Smart, and Vivifi’s Roam Asia Super 5G+ all land around this price point. Anything cheaper than that is typically tied to a promotion with its own terms and conditions — meet those conditions, and the price can come down to around $10-$12, which is exactly the pattern with Zero1’s own Movemo Vibe above.

Between the three $15 options, I’d lean towards Zero1 or ZYM over Vivifi specifically for one reason: both Zero1 and ZYM have an actual physical customer service centre you can walk into if something goes wrong, while Vivifi is fully digital-first with only self-collection points for SIM pickup, not staffed support. If in-person support matters to you, that’s worth factoring in alongside the price.

How Zero1’s Referral Program Works

Zero1 runs a genuine two-way referral system, per their official Refer & Earn programme:

• You (the new subscriber) get a S$1-S$2 rebate off your second bill, depending on the plan you sign up for.
• I (the referrer) get the same S$1-S$2 rebate on my own bill, credited within 3 months once you’ve successfully paid your second bill.
• To qualify as a new subscriber, you need to not have had an active Zero1 service in the past 3 months, and you can’t share the same NRIC/FIN as the referrer.
• Rebates are applied automatically as bill credit — they can’t be split, transferred, or cashed out.

Quick Checklist: Are You Ready to Sign Up for Zero1?

Before you start, make sure you’ve got these sorted:

• A Singpass account, since Zero1’s sign-up flow verifies your details via Singpass
• Your NRIC/FIN, with your existing number (if porting in) already registered under your own name
• A valid credit or debit card for monthly auto-deduction
• A decision on delivery method — courier, mail, or self-collection at Zero1’s Tai Seng service centre — since this affects how quickly you’re up and running
• Confirmation you’re under the 10 postpaid SIM limit across all telcos, which you can check at go.gov.sg/SimCardHowMany

Get these sorted first, and your sign-up should go smoothly from start to finish.

What to Expect After Redeeming the Code

• You (the new subscriber): your S$1-S$2 bill rebate is applied automatically within 2 months of signing up, as a credit on your bill.
• The referrer: their rebate is applied within 3 months, but only after you’ve successfully paid your second bill.
• If either of you earn multiple referral credits in the same month, they’ll appear combined as a single line on the bill rather than separately.

Frequently Asked Questions

Can I use more than one referral code? No — only one referral code can be applied per new sign-up, entered in the Referrer Code field at checkout.

Does it matter whose referral code I use? Not for your own rebate — any valid Zero1 referral code gets you the same S$1-S$2 off your second bill. The only difference is who receives the referrer credit, so you might as well use one from someone whose content actually helped you decide.

Is there a minimum spend to use the code? No minimum spend is required, though the rebate amount depends on the plan you choose.

Is there a membership fee to join Zero1? No. Zero1 is a no-contract, SIM-only MVNO — you pay your monthly plan fee and nothing else.

Does the referral code work on any Zero1 plan? Yes, as long as it’s an eligible plan under the Refer & Earn programme — this covers the standard consumer plans, including Movemo Vibe, Streamo Freedom, and Movemo Dash.

Can I use a referral code if I’m porting a number for a family member? You can, but the person signing up (the referee) must be a different individual from the referrer and can’t share the same NRIC/FIN. If you’re managing the line for a parent, make sure the sign-up is properly under their own identity, not yours.

How long does it take to receive my bill rebate? New subscribers typically see their rebate within 2 months. Referrers receive theirs within 3 months, after the referee’s second bill has been paid.

Disclosure: I earn a referral credit when you sign up using code Z18QNTY1. One rule I stick to: I only recommend products and services I actually use myself — referral reward or not.
