GOMO Sim Only Plan Singapore: My Honest Review, 7 Years Later

Back in May 2021, a reader named Susan left a comment thanking me for this post. I replied: “Talking about GOMO, this is a rather old post… I think a refresh is due soon!”

That was 2021. It’s now 2026. Oops.

In my defence, GOMO barely gave me a reason to revisit — I’ve quietly stayed on the plan this entire time, which is either the highest compliment I can pay a telco or a sign that I just really don’t like changing SIM cards. Probably both. But between then and now, GOMO has changed enough that the original 2019 post is honestly a bit misleading if you’re using it to decide today. So here’s the update.

This post is part of my Singapore Mobile Plans series. If you want the full picture across seven MVNOs I’ve tried — Gomo, Zero1, ZYM, Circles.life, Maxx, MyRepublic and giga — start with my cornerstone comparison post. This one’s the deep-dive on the plan I actually use day to day.

Full disclosure though — “quietly stayed on GOMO this entire time” isn’t quite accurate. Over these 7 years I’ve actually bounced through Circles.life, M1, and Maxx, among others, chasing a cheaper bill or a shinier promo each time. And each time, I’ve found my way back to GOMO. Not because the other plans were bad — some were genuinely cheaper — but because I kept missing the one thing GOMO never made me think twice about: coverage. That pattern alone is probably the most honest endorsement I can give it.

What’s actually changed since 2019

Let me set the scene. In 2019, I signed up for 20GB data, 200 minutes, 200 SMS for S$20/month, and I remember thinking that was a steal.

Fast forward to today, and GOMO’s cheapest plan alone gives you 200GB of data for S$12/month — ten times the data, for less money. Their 5G+ plans go up further from there, and roaming has expanded from “10 destinations, $10 for 1GB” to up to 50 countries, from S$6/GB, with local-rate roaming in Indonesia, the Philippines, and Thailand from as low as S$5. The old “no data roaming at launch” complaint I had in 2019 feels almost quaint now.

The bigger shift, though, is 5G+. GOMO’s 5G+ runs on Singtel’s network with a recent 700MHz upgrade, which on paper means better indoor penetration and stronger signal. In practice, it’s not just marketing — I’ll get into that below.

5G+ speed: blazing, no asterisk needed

I’ll say it plainly: 5G+ has been genuinely fast for me. Not “fast for a budget SIM” fast — just fast, full stop. Streaming, tethering, the usual load of apps refreshing in the background — none of it has given me a reason to think twice about which telco I’m on. This is the one area where GOMO in 2026 doesn’t feel like a compromise at all.

Coverage: still Singtel, still solid

This hasn’t changed, and honestly, it was never in question. GOMO rides on Singtel’s actual network, not some secondary MVNO infrastructure, so coverage has always been — and still is — top notch. If you’ve had good Singtel coverage before, you’ll have it here too. This was true in 2019 and it’s true today. It’s also, frankly, why I kept coming back after every detour to a cheaper plan elsewhere — the savings never quite made up for the moments of no signal.

Customer service: slow, not necessarily bad

Here’s where I want to be precise instead of just repeating my old complaint. Customer service is still slow — that part hasn’t budged much in 7 years. But “slow” and “poor” aren’t the same thing. When I’ve eventually gotten through, the people on the other end have generally been competent and have resolved my issue. The problem has always been the wait, not the outcome. If you’re someone who needs same-day answers to billing questions, factor that in. If you can tolerate a bit of a queue for genuinely no-hidden-fee pricing, it’s a fair trade.

So what does GOMO cost now?

I’m on the GOMO 5G+ Value plan, which as of writing (July 2026) runs S$19.99/month — though there’s currently a promo bringing it down to S$10/month for the first 3 months. Here’s what that gets you:

• 400GB data in Singapore
• 400GB roaming data in Malaysia, Indonesia, Thailand & Australia
• 28GB Asia roaming (24 destinations)
• 10GB Worldwide roaming (210 destinations)
• 800 mins + 800 SMS + 800 IDD mins

It’s not the cheapest plan out there — there are lighter GOMO tiers that start well below this, and other MVNOs on M1 or StarHub can undercut it too. But between the local data, the roaming, and the fact that it’s Singtel’s actual network underneath, I’ve been comfortable paying a bit more for the peace of mind.

Compare this to my 2019 numbers — 20GB, no roaming, S$20/month — and it’s not close. GOMO has become significantly more generous even as it’s added 5G.

If you’re shopping for this plan for yourself, the 5G+ Value tier above is what I use. If you’re doing this for an elderly parent instead, GOMO also runs a dedicated $6/month Senior Plan — I wrote in detail about porting my mum’s line onto it from Circles.life, including a name-ownership mistake that delayed things by weeks. Worth a read before you start if you’re in a similar spot.

Thinking of switching? Sign up for GOMO with my referral code G52Z7R — it works on any GOMO plan, not just the 5G+ Value one above. You get a S$3 Grab voucher, and I get a S$5 Grab voucher once your sign-up completes. For the full referral program details, plan-by-plan breakdown, and what to expect after signing up, see my dedicated Gomo Referral Code guide. I’ve been on this plan for 7 years now, so this isn’t a “try it and hope” recommendation — it’s a “this is what I actually use” one.

The verdict, updated

Same conclusion I had in 2019, just with better numbers behind it: I’d recommend GOMO if you want Singtel-grade coverage and speed without Singtel-grade pricing, and if you’re not the type who needs instant customer support turnaround. I’m still not a power user, but even power users are better served today than they were in 2019 — 200GB+ base plans cover a lot more use cases than the old 20GB tier ever did.

If live-chat wait times are a dealbreaker for you, that’s the one honest caveat I’ll keep repeating. Everything else — price, data, coverage, 5G+ speed — has only gotten better since I first wrote this.

Got questions about switching, or curious how GOMO compares to what you’re on now? Drop a comment — I still read and reply to every one, even years later, apparently. And if you want to see how GOMO stacks up against six other MVNOs I’ve tried, my full 2026 comparison has the breakdown.

Referral code: G52Z7R — works on any GOMO plan. You get S$3 in Grab credit, I get S$5, once your sign-up completes. Use it if this helped you decide.
