You've Sorted Your Travel Money. Have You Sorted Your Mobile Plan?

You've sorted your travel money. You know to head to People's Park before a trip, not ChangiFX. You check the rates, you time the exchange, you save yourself S$14 on a US$3,000 conversion without thinking twice.   

Your mobile plan hasn't had that kind of attention in years. Most pay $30 to $60 a month, and they couldn't tell offhand what they're actually getting for it—how much data they use, whether roaming is included, or when they last checked if a better plan existed.

If you haven't compared mobile plans in the last year, this is worth 10 minutes of your time.

[ms-toc title="Are you overpaying your mobile plan in Singapore?"]

What are you paying for on your mobile plan right now?

Before comparing anything, it helps to know what you're currently on. Four things worth pulling up:

1. How much data you actually use. Open your telco app and check your average monthly usage over the last three months. If you're consistently using under 30GB and paying for 200GB, you're funding headroom you'll never touch. If you're on an older plan with a low data cap and travelling more than you used to, you may be hitting your limit and paying extra without realising it.   
2. Whether roaming is bundled or charged per trip. Most postpaid plans don't include roaming. You add it separately, usually the night before a flight, and the cost rarely gets a second look.   
3. Whether you're still in a 24-month contract. If yes, check your end date and any early termination fees before making a move.
4. When you last checked if a better plan existed. Plans that cost $40 two years ago now have direct equivalents at $20. Most people just never bother to check.

Does a cheaper mobile plan mean worse coverage in Singapore?

For most people: no.

Coverage in Singapore comes down to which network your plan runs on. Three main operators run their own infrastructure: Singtel, StarHub, and the recently merged Simba-M. Any plan you sign up for runs on one of these three networks, regardless of the Telco brand. For instance, GOMO runs directly on Singtel's 5G+ network, meaning its subscribers get the same coverage quality as any Singtel postpaid customer.  

This matters because networks aren't equal in performance. Across the board, Opensignal ranks Singtel first for Reliability Experience in Singapore—the measure of how consistently you stay connected across different locations and times of day.

What does roaming cost when it's not built into your plan?

Most Singaporeans buy roaming per trip. You activate the add-on the night before departure, usually without tallying the cumulative cost across a full year of travel.

Individual add-on prices don't look too costly. As a typical Singaporean travelling each year, the numbers stack up:

*Tabulated from other telco providers’ current roaming plans as of 19 May 2026.

That works out to about $12 to $120 a year spent per GB on roaming alone. On the right plan, this cost can already be built into what you pay monthly.

With GOMO by Singtel, roaming is included upfront in its 5G+ plans, so there’s no need to activate add-ons or make last-minute purchases before a trip. 

Priced at $20.99/month, the 5G+ CORE plan includes:

• 700GB local 5G+ data. Enough to stream, hotspot your laptop for work, and still have data left
• 700GB Malaysia roaming. Covers regular weekend JB trips without watching the counter
• 12GB Asia roaming across 18 destinations. A full week in Bangkok with Maps, Grab, and video calls to spare
• 12GB worldwide roaming across 50 destinations. Covers the basics on a longer-haul trip to Japan or Europe

For frequent travellers or remote workers, the 5G+ GLOBAL INFINITY plan covers unlimited worldwide roaming across the same 50 destinations at $50/month. Think month-long trips, back-to-back work travel, or not hesitating capturing moments on social media because of data caps.

Both have no contractual obligation. Moreover, extra monthly data can be converted into GB coins with GOMO’s Data Bank, redeemable for perks like local or roaming data, and rewards such as Grab Travel Pass. Your data only builds up rather than disappearing at the end of each billing cycle.

Which SIM-Only plan is best for different types of users? 

A 63-year-old using her phone for WhatsApp, Grab, and video calls with family overseas has very different needs from a 21-year-old streaming TikTok between lectures and tethering data in the library. Most mobile plans, however, are still priced for a generic “average user” — one that doesn’t really reflect how people use their phones day to day.

That’s where GOMO’s latest plans take a slightly different approach. They design their pricing and bundles around how people actually use their data day to day. Making it easier to pick a plan that actually fits how you use your data.

Best for 60 and above: 5G+ Senior Plan at $6/month

Are you reliant on your phone for everyday tasks like messaging, calls, and occasional browsing? You don’t need an expensive plan. What matters more is reliability and simplicity.

The 5G+ Senior plan offers 400GB of local data on Singtel’s 5G+ network, along with:

• 400GB Malaysia roaming. Covers regular JB trips without needing a separate add-on
• 6GB Asia roaming across 18 destinations. Enough for a short trip to Taiwan or Japan
• 3GB worldwide roaming across 50 destinations. Basics covered for the occasional longer trip
• 800 minutes of calls and 800 SMS

Everything is managed through the GOMO app. No contract, no store visits, and no paperwork.

When it comes to your weekly grocery shopping at Johor Bahru, 400GB of roaming keeps you connected and entertained while sticking it out at long custom queues without needing an add-on. For $6 a month, it’s a steal.

Best for 16 to 24: 5G+ Student & NS Plan at $12/month

You are likely using more data day to day for streaming, gaming, and staying connected. Forget to connect to your house Wi-Fi during holidays / weekends or bursting your data by a mile while travelling to and fro school? The 5G+ Student and NS plan is built to save you from exorbitant bills and your parent’s fury. You get:

• 400GB local data on 5G+
• 400GB Malaysia roaming. JB trips and school camps covered without add-ons
• 12GB Asia roaming across 18 destinations. A full week abroad without rationing data
• 4GB worldwide roaming. Enough for a short exchange programme or holiday

This gives you more headroom for travel and heavier usage for the in between zone outs and entertainment fillers without needing to upgrade your plan.

Both plans sit alongside GOMO's line-up for working adults and frequent travellers, meaning the full range now covers every life stage within the same network:

*Fair usage policy applies. Unlimited local data up to 1,024GB; unlimited worldwide roaming up to 25GB, then throttled.

How do you switch mobile plans and keep your number?

Number porting is the most common reason people put off switching. Most people assume it’s complicated. In fact, the process takes under 10 minutes to start. You get to keep your number throughout.

Here's how it works:

1. Check your current plan for any remaining contract period and early termination fees.
2. Sign up at gomo.sg. Choose eSIM for instant activation or physical SIM for same-day delivery.
3. During sign-up, select "port my number" and enter your current number.
4. Keep using your existing SIM as normal while GOMO processes the transfer. Port-ins from non-Singtel operators take up to 3 working days.
5. Once the port-in completes, activate your GOMO SIM. Your number transfers automatically.

For the Senior and Student & NS plans, there's an additional SingPass age-verification step at checkout. The rest of the process is the same.

The bill that keeps quietly running

If you haven't compared plans recently, it may be worth checking what newer options offer. You can explore options like GOMO by Singtel, which has 5G+ plans from $6/month with no contract, covering everything from light everyday use to unlimited worldwide roaming.
