Anyone who has crossed the Johor-Singapore Causeway more than twice knows that staying connected on both sides is a headache traditional roaming plans never quite fixed.

Here are the key facts to consider at a glance.

Which Telco in Singapore Has the Best Coverage?

How do Singtel, M1, StarHub, and SIMBA compare in coverage?

• Singtel’s 5G+ network reaches over 95% of the island, according to the Singtel blog (updated June 2026).
• M1 and StarHub share a joint 5G network that is competitive in urban corridors but reportedly weaker in rural zones (Yahoo News Singapore).
• SIMBA (formerly TPG) uses its own 4G/5G infrastructure and has improved coverage in recent years, though it still lags behind the incumbents in MRT tunnels and HDB estates (Seedly review, 2026-06-30).

What does the June 2025 Mobile Network Experience Report say?

Opensignal’s June 2025 report, covered by Yahoo News Singapore, ranks Singtel first for coverage experience, with M1 and StarHub tied for second. SIMBA scored lower but showed the fastest improvement in download speeds over the previous six months.

The implication: your choice hinges on whether you prioritise rock-solid local connectivity or affordable roaming.

What Is the Best Mobile Plan in Singapore for 2026?

SIM-only vs contract plans

The market has moved overwhelmingly toward no-contract SIM-only plans. All the borderless plans listed here are month-to-month, with no lock-in. The trade-off: you lose device subsidies, but you gain flexibility and lower monthly fees.

Best plans for heavy data users

• Circles.Life Pro: 600GB local + Malaysia roaming + global roaming data, $14.88 first month then $22 (Circles.Life comparison guide).
• Eight Triple Eight: 688GB local data, free roaming in 58+ destinations, $18/mo (Eight official site).

Best budget plans

• GOMO $7.50 plan: 200GB local + 6GB roaming (Malaysia, Indonesia, Thailand, Taiwan, Australia) – the cheapest entry with roaming (Yahoo News Singapore).
• SIMBA SuperRoam 10: $10/mo, 300GB local/roaming in Singapore, Malaysia, Hong Kong, plus 12GB in 7 other Asian destinations (Yahoo News Singapore).

The pattern: mid-range plans ($10–18) offer the best roaming value per dollar.

Which Telco Has the Best Roaming Plan?

Borderless vs traditional roaming add-ons

Traditional roaming add-ons (e.g., Singtel’s DataRoam, M1’s Roam Like Home) charge per-day or per-MB fees that can balloon. Borderless plans include roaming data in the monthly subscription — you don’t have to top up or activate anything.

SIMBA SuperRoam 10 details

SIMBA’s SuperRoam 10 plan offers 10GB of roaming data each month across 10 Asia-Pacific countries: Malaysia, Indonesia, Thailand, Taiwan, Hong Kong, Macau, Japan, South Korea, Australia, and New Zealand. The plan costs $10/mo and is no-contract (Yahoo News Singapore).

Circles.Life borderless 8 countries

Circles.Life’s borderless plan provides 100GB of data usable across 8 Asian destinations including Malaysia, Indonesia, Thailand, Taiwan, South Korea, Japan, Hong Kong, and China. The plan starts at $18/mo (Yahoo News Singapore).

GOMO 6GB roaming

GOMO’s $7.50 plan includes 6GB roaming data that works in Malaysia, Indonesia, Thailand, Taiwan, and Australia. It piggybacks on Singtel’s network, so coverage is strong. While 6GB is modest, the price makes it a no-brainer for light roamers (Yahoo News Singapore).

Eight roaming coverage

Eight’s 5G Value Eight Plan ($18/mo) includes 528GB local data and free roaming in over 58 destinations worldwide. The coverage is extremely broad, but the roaming data speed may be throttled after a certain cap (Eight official site).

The catch: each plan’s value depends on how many countries you actually visit.

What Is the Cheapest Telco in Singapore?

SIMBA low-cost plans

SIMBA’s entry-level plan costs just $5/mo for 10GB local data, but without roaming. The SuperRoam 10 at $10/mo is the cheapest borderless option across the market (Yahoo News Singapore).

Eight $8 plan

Eight’s 4G Double Eight Plan offers 528GB local data at $8/mo — the lowest price per GB on the market. It does not include roaming, but the $18 version does (Eight official site).

GOMO $7.50 plan

The GOMO $7.50 plan (200GB local + 6GB roaming) is the cheapest plan with any roaming included. It is fully digital and no-contract (Yahoo News Singapore).

M1 Bespoke budget

M1’s Bespoke 5G Max plan at $14.95 offers unlimited local data but no roaming. For borderless needs, you must add a roaming pack, which pushes the cost higher than the all-in plans from SIMBA or Circles.Life (Yahoo News Singapore).

The implication: the cheapest option depends entirely on whether roaming is a requirement.

Is SIMBA Better Than Singtel? And Other Telco Comparisons

SIMBA vs Singtel coverage

Singtel has superior overall coverage, especially in MRT tunnels and suburban HDB estates. SIMBA’s network, while improving, still has gaps in northern Singapore (Seedly review, 2026-06-30).

SIMBA vs Singtel data speeds

Opensignal’s June 2025 report (cited by Yahoo News Singapore) shows Singtel leads in download and upload speeds. SIMBA has improved but still trails by roughly 30% in median speeds.

SIMBA vs Singtel roaming

SIMBA offers far more generous roaming data for the price: 10GB in 10 countries vs Singtel’s roaming add-ons that cost $5–$10 per day. For the frequent cross-border traveller, SIMBA wins on roaming value (Yahoo News Singapore).

M1 vs Singtel

M1 offers a middle ground: its Bespoke 5G Max plan at $14.95 includes unlimited local data, but roaming add-ons make it less competitive for borderless use. Singtel’s strength is its network reliability and priority support (Singtel blog).

The pattern: your choice boils down to whether you prioritise coverage or roaming value.

What Are the Best Borderless Plans for Tourists and Seniors?

Best prepaid SIM cards for tourists

• SIMBA Prepaid: $10 top-up gives 10GB local data + 1GB roaming to Malaysia/Indonesia. No registration hassle (Yahoo News Singapore).
• Eight Prepaid: $8 for 528GB local data, with roaming available as an add-on (Eight official site).

Borderless plans for seniors

Seniors often prefer simplicity and no hidden fees. GOMO’s fully digital plan ($7.50) is straightforward: one price, no surprises. Circles.Life also has a simple no-contract setup that family members can manage online (Circles.Life plans page).

Short-term vs long-term options

For a two-week holiday, a prepaid SIM from SIMBA or Eight is best because you don’t need to cancel later. If you’re a frequent visitor staying a month or more, a postpaid borderless plan like SIMBA SuperRoam 10 or Circles.Life gives better value and more data.

What this means: for short stays, prepaid wins; for longer visits, postpaid borderless plans offer the best value.

Comparison Table: Borderless Plans Side by Side

Six plans, one pattern: the cheaper the plan, the fewer roaming countries covered, but the value per GB is highest in the mid-range.

The implication: mid-range plans offer the best balance of roaming breadth and cost.

Specifications Table: What Each Plan Includes Beyond Data

Seven specs, one gap: unlimited data is now the norm, but borderless plans still cap roaming while local data is virtually unlimited.

The pattern: all cheaper plans cap local data, but only the most expensive plans include roaming calls.

Pros and Cons of Borderless Plans

The net effect: borderless plans simplify travel for most users, but heavy roamers need to watch FUP limits.

Timeline: How Borderless Plans Evolved

• September 2023 – Circles.Life launches first borderless mobile plan with 100GB across 8 Asian countries (Yahoo News Singapore)

What Users Are Saying

“I run 2 SIMs (Simba and Eight), for $18/month. There’s enough failsafe to go around, good roaming…”

The race to zero roaming is real. For the frequent Causeway crosser or the annual Bali holidaymaker, borderless plans have already made traditional roaming add-ons obsolete. For the heavy data user who rarely leaves Singapore, the value is less compelling — you’re paying for roaming data you may never use. But as the line between local and international data continues to blur, one thing is certain: the telco that offers the simplest, cheapest borderless experience will win the next million subscribers.
