Singtel vs StarHub vs M1 vs Circles.Life Mobile Plans 2026: The Honest SG Telco Comparison

Updated: October 2026.

If you are switching telcos between October 5 and November 4, 2026, the timing is on your side, so pick the best of the four, then sign up through ShopBack before you pay, where ShopBack Cashback works like a discount, only easier than a promo code. The decision this article helps with is which of the four to port your number to. Picking a Singapore telco in 2026 is not really about who is cheapest, since per-gigabyte prices have largely converged; it is about what you bundle around the SIM, whether a family's lines, a Disney+ subscription, roaming for frequent trips, or nothing at all. Get that match wrong and you either overpay for data you never touch or lose bundle savings you would actually use. Check ShopBack before you sign up, since the port-in itself can earn cashback where the telco is listed.

Under IMDA rules, Mobile Number Portability is a licence obligation for all mobile operators, so you keep your number when you switch, at no cost (IMDA Mobile Number Portability information paper, IMDA). That structural condition is why switching is a real lever in Singapore rather than a theoretical one.

The verdict

For Singapore mobile users in 2026, the four mainstream telcos compete on different axes. Circles.Life wins on raw SIM-only price and contract flexibility (S$20 to S$28/month for 50GB to 100GB, no contract). Singtel wins on family bundling, 5G priority, and overseas roaming bundles. StarHub wins on entertainment bundles (Disney+, HBO Max). M1 wins on SIM-only data caps (no overage charge, just speed throttling). Sub-brand MVNOs GOMO (Singtel) and giga! (StarHub) cover the no-contract value lane. The right call is matching your dominant need (price, family, entertainment, data flexibility) to the right telco.

How the four telcos really differ

Of the four telcos below, Circles.Life is listed on ShopBack Singapore (as is Singtel's GOMO sub-brand), so if either fits you can complete the sign-up through ShopBack. Singtel, StarHub and M1 are not currently listed. The Singapore mobile market has consolidated to four meaningful operators: Singtel, StarHub, M1, and Circles.Life. After TPG (now Simba) acquisition shifts and MVNO proliferation, the practical SIM-only choice is between roughly 8 to 10 brands, of which four matter for everyday consumers.

Singtel runs one of Singapore's two nationwide 5G standalone networks (the other is jointly operated by StarHub and M1), with broad underground and MRT coverage. SIM-only plans start at S$32/month for 100GB with 5G access. Contract phone bundles start at S$45/month for entry-level smartphones. Family bundles (Singtel Multi-Line) discount additional lines by S$10 to S$15/month each. International roaming via ReadyRoam or specific country passes is a strong differentiator, with day passes for popular Asia destinations at S$15 to S$25.

StarHub offers slightly cheaper headline SIM-only plans at S$28 to S$35/month for 100GB. Bundle value comes from entertainment: StarHub TV+, Disney+ Premium, and HBO Max included in higher tiers. 5G coverage is jointly developed with M1 (separate spectrum allocation but cross-shared infrastructure on some cells). International roaming is competitive but less generous than Singtel.

M1 has the most flexible SIM-only structure: select tiers offer no overage charge, just speed throttling to 256kbps after the data cap, which makes the plan friendlier for users who occasionally burst above their cap. SIM-only plans start at S$25/month for 80GB. Coverage is strong in urban and MRT areas, slightly weaker in remote industrial zones.

Circles.Life is the digital-first, no-contract operator running on M1's network as an MVNO. SIM-only plans start at S$20/month for 50GB with unlimited talk and SMS. The product UI is the slickest of the four (full self-service app, instant data top-ups, easy plan changes). Roaming and customer service have historically been more friction-heavy than the MNOs.

Sub-brand value players: GOMO (Singtel) at S$18 to S$25/month, giga! (StarHub) at S$18 to S$25/month, MyRepublic Mobile, and Simba (formerly TPG) at S$10 to S$15/month with smaller data buckets. For users prioritising raw price, the value brands undercut the headline four, with the trade-off of thinner customer service.

The cost structures are converging because spectrum capacity and 5G infrastructure economics push baseline data prices down. The differentiation is increasingly bundle-driven (family, entertainment, broadband, roaming) rather than per-GB price.

The plans side by side

Of the operators in the grid below, Circles.Life is the one listed on ShopBack Singapore; check the live Cashback rate on its ShopBack page.

Plan	Singtel	StarHub	M1	Circles.Life
Cheapest SIM-only (data)	S$32 / 100GB	S$28 / 100GB	S$25 / 80GB	S$20 / 50GB

Annual price stability	Stable	Stable	Stable	Promo-driven, can shift
Sub-brand option	GOMO from S$18	giga! from S$18	maxx from S$22	n/a

The plan prices, data buckets, and bundle benefits above are illustrative of mid-2026 promotional pricing and change frequently; confirm current plans on each telco's official site (linked in Sources) before switching. The parts that hold steady are structural: number portability is mandated by IMDA, Singtel runs one nationwide 5G standalone network, StarHub and M1 jointly run the other, and Circles.Life is an MVNO on M1's network.

The readout: at the cheapest SIM-only tier, Circles.Life wins on price. At the mid-tier, the gap closes; Circles.Life is S$12 to S$17/month cheaper than the MNOs for similar data. At the unlimited tier, Circles.Life saves you S$30+/month versus the MNOs, with the trade-off of thinner customer service.

What's shifted in 2026

Four telco-side shifts worth pricing in before you switch this year:

• 5G tiers are now standard, not premium: All four operators include 5G access at their entry SIM-only tier (Circles.Life from the S$28+ tier). The 5G surcharge that existed in 2023 to 2024 has been priced into the base plans.
• Roaming day-pass geography expanded: Singtel ReadyRoam, StarHub DataTravel, and M1 Data Passport all added more destinations for the S$15 to S$25 day-pass tier in late 2025 and early 2026, including secondary Japan cities, more of Vietnam, and select European destinations.
• Broadband + mobile bundles compress on renewal: Singtel and StarHub both push renewal bundles that pair 1 to 2 Gbps home fibre with mobile lines at S$10 to S$15 off per mobile line. Time renewal to the promo cycle around 8.8, 9.9, and 11.11 for the biggest gap.
• MVNO price floor is holding: Circles.Life, GOMO, giga!, and Simba are stable in the S$18 to S$28/month band for 50 to 100GB no-contract SIMs; the aggressive undercut year-on-year has settled.

The practical takeaway: baseline SIM-only pricing is flatter than in 2024 to 2025; bundle stacking (family + broadband + entertainment or roaming) is now where the meaningful savings sit.

Matching a telco to your usage

Match the telco to your primary need. If you mostly use mobile for messaging, social media, and occasional video, you do not need a 200GB plan. If you tether constantly or work from public Wi-Fi-poor locations, the unlimited plans pay for themselves.

Profile	Recommended	Plan tier	Monthly cost
Light user (under 30GB/month), no family bundle	Circles.Life or GOMO	50GB SIM-only	S$18 to S$20
Heavy data user (100GB+), price-conscious	Circles.Life	100GB SIM-only	S$28
Family of 4, broadband at home, Disney+ subscriber	StarHub	Mobile + broadband + TV bundle	~S$135 to S$170/month family total
Singtel customer with broadband already	Singtel	Multi-Line SIM-only	S$25 to S$32/line with discount
Frequent traveller to Japan, Korea, Australia	Singtel	SIM-only with ReadyRoam	S$45 + S$15-25/trip
Heavy tethering, work from cafes	M1 or Singtel	Unlimited tier	S$70 to S$80
Tech-savvy, hates phone calls and shop visits	Circles.Life	50GB or 100GB	S$20 to S$28
Senior or non-tech-savvy user	Singtel or StarHub	Mid-tier SIM-only	S$32 to S$45
Need separate work line	GOMO or giga!	30GB to 50GB	S$15 to S$22
Roaming-heavy across SEA	Singtel ReadyRoam Asia Pass	SIM-only + add-on	S$32 + S$45-90/month roaming

The most common mistake is paying for an unlimited plan when actual usage averages 25 to 40GB/month. A 100GB plan at S$28 (Circles.Life) covers 99% of consumer use cases and saves S$50/month versus unlimited.

What this means for your bill

In practice, this means a typical Singapore user with around 30GB/month of usage and no need for entertainment bundles should be on a Circles.Life 50GB plan at S$20/month, total annual cost S$240. The Singtel equivalent (50GB tier) sits around S$30/month, total S$360/year. The S$120/year saving compounds: across 5 years that is S$600, enough for a mid-tier smartphone outright.

A second example: a family of 4 with Singtel home broadband already at S$50/month. Singtel Multi-Line lets you add 4 SIM-only lines at S$25 to S$32 each with the multi-line discount. Total: S$50 broadband + 4 x S$28 mobile = S$162/month for the household. Switching all mobile lines to Circles.Life at S$20 each saves S$32/month (S$384/year) but loses the broadband bundle integration, the multi-line discount, and unified billing. The Circles.Life net saving is real but smaller than the headline price gap suggests once the broadband interaction is honest.

A third example: a remote worker who tethers heavily (60 to 100GB/month) and travels regionally 4 to 6 times a year. M1 SIM-only unlimited at S$70/month covers the data without overage surprises, M1 Data Passport at S$15 to S$20 per trip handles regional roaming, total annual cost S$840 mobile + S$80 to S$120 roaming = roughly S$920 to S$960. The Circles.Life unlimited tier (S$48/month) would save S$22/month domestically but Circles.Life roaming is less competitive in 2026, so M1's roaming structure recovers the gap for frequent travellers.

If you sign up with Circles.Life or GOMO, go through ShopBack before you complete the sign-up so part of the cost comes back as Cashback. Check the live rate on the store's ShopBack page, since amounts vary by plan tier and promotion period.

When this does NOT apply

• You need landline-style customer service. Circles.Life is app and chat only. If you prefer walking into a shop to debug a billing issue, Singtel, StarHub, or M1 is the right structural choice.
• Your company reimburses your plan in full. If reimbursement is unconditional, the cheapest plan is irrelevant. Pick by network preference, family integration, or roaming.
• You hold corporate-discounted plans through your employer. Many large SG employers negotiate group discounts with Singtel or StarHub that beat any retail SIM-only offer.
• You live in a 5G-thin area. Coverage maps in 2026 are excellent for all four telcos in urban Singapore, but if you spend significant time at the edges of Jurong Island, Tuas, or industrial Pioneer, run a 30-day SIM trial before committing.
• You hate variable promo pricing. Circles.Life has historically run promo-driven pricing that can shift on renewal. The MNOs tend toward stable list pricing with less surprise.
• You bundle home internet, mobile, and pay TV. Bundle savings from Singtel or StarHub can exceed Circles.Life's price advantage on the standalone SIM. Run the bundle math.

Frequently asked questions

Is Circles.Life owned by Singtel?

Circles.Life is operationally independent and runs on M1's network as an MVNO (Mobile Virtual Network Operator); it is not owned by Singtel. (GOMO, by contrast, is Singtel's own sub-brand on Singtel's network.) Circles.Life's customer service, billing, and product roadmap are independent, but your data is carried on M1 cells. ShopBack Singapore lists Cashback on new Circles.Life sign-ups via shopback.sg/circles-life when the order is completed through the ShopBack Chrome extension or app in-app browser.

What happened to TPG / Simba in Singapore?

TPG Telecom rebranded its Singapore operation to Simba in 2023. Simba operates as a budget MVNO with very aggressive SIM-only pricing (S$10 to S$15/month for 50GB to 80GB in 2026). Coverage is on its own network rebuilt from the original TPG spectrum. Customer service and reliability are thinner than the major four, but the pricing is hard to ignore for cost-first shoppers. If you want a listed ShopBack store, Circles.Life (on M1's network) and GOMO (Singtel's sub-brand) are both on ShopBack Singapore.

Can I keep my mobile number when switching telcos?

Yes. Mobile Number Portability (MNP) is mandated by IMDA as a free service and is a condition in every mobile operator's licence (IMDA, Mobile Number Portability). The switch typically takes 1 to 3 working days and is initiated by the new telco. You do not need to interact with the old telco directly; they receive the port-out request and process it automatically. If you are moving to Circles.Life or GOMO, start the sign-up through ShopBack.

Is 5G genuinely faster than 4G in Singapore in 2026?

On a clean cell, yes; 5G typically delivers 200 to 600 Mbps download in urban Singapore in 2026, versus 50 to 150 Mbps for 4G LTE. For most consumer use (streaming 4K, video calls, app downloads), the difference is invisible. For tethering laptops to work, the 5G headroom is genuinely useful. If you sign up with Circles.Life or GOMO, go through ShopBack first and check the live Cashback rate on the store's ShopBack page.

Should I buy a phone on contract or outright in 2026?

Almost always outright. A flagship phone (iPhone 17 Pro, Samsung Galaxy S26) costs S$1,500 to S$2,000 outright or S$50 to S$100/month on a 24-month contract that ties you to a S$50 to S$80/month mobile plan. The 24-month total contract value is typically S$2,800 to S$4,500. Buying outright and adding a no-contract SIM-only plan at S$20 to S$48/month gives the same phone for S$1,980 to S$3,150 total over 24 months, with the freedom to switch plans whenever.

How does ShopBack interact with telco sign-ups?

Of the four, Circles.Life is listed on ShopBack Singapore, as is Singtel's GOMO sub-brand; Singtel, StarHub and M1 are not currently listed on ShopBack. Check the live rate on the store's ShopBack page, since amounts vary by plan and promotion period. For families adding multiple lines, each qualifying new sign-up can earn its own Cashback.

Where can I buy a phone outright in Singapore with ShopBack cashback?

The main outright-purchase routes on ShopBack Singapore for handsets are Apple Online Store for iPhone, Amazon SG for Android and Apple stock, Lazada for LazMall brand stores (Samsung, Xiaomi, Oppo), and Shopee for Shopee Mall brand stores. Go through ShopBack before you pay. Rates change monthly; verify the current rate on each merchant page.

Do phone accessory purchases earn cashback on ShopBack Singapore?

Yes. Cases, chargers, cables, screen protectors, and earbuds bought on Amazon SG, Lazada, or Shopee track cashback the same way as any other basket. Cashback is calculated on the eligible order value after any excluded categories. Rates differ between platforms and change monthly; check the current published rate on each merchant page before you buy.

Can I use Shopee Coins and Lazada vouchers on a phone purchase and still earn ShopBack Cashback?

In most cases, yes. Cashback tracks on the qualifying order value after platform vouchers are applied. Coins redemption may reduce the eligible order value, depending on how each platform reports the order to ShopBack. Rates and terms can change monthly, so check Lazada or Shopee for the current basis before you use coins on a phone or accessory basket.

How do I earn cashback on Apple accessories in Singapore?

Apple Online Store is a ShopBack Singapore partner. Go through ShopBack before you pay for AirPods, chargers, MagSafe accessories, cases, or AppleCare+. Cashback tracks on the eligible order value. Rates change monthly and can vary by category; verify the current rate on Apple Online Store before checkout.

Which of these telcos can I sign up with through ShopBack?

Of the four, Circles.Life is listed on ShopBack Singapore, as is Singtel's GOMO sub-brand; Singtel, StarHub and M1 are not currently listed on ShopBack. For a Circles.Life or GOMO plan, go through ShopBack at shopback.sg/circles-life or shopback.sg/gomo before you complete the online sign-up. Cashback tracks per successful qualifying sign-up and can vary by plan tier; check the live rate on the store's ShopBack page before signing up.

How long does ShopBack cashback take to appear after a Singapore phone or telco purchase?

Pending cashback typically appears in your ShopBack account within 48 hours of the qualifying order. It moves to confirmed status after the merchant's return or contract-completion window closes, which is 30 to 90 days for retail merchants (Amazon SG, Lazada, Shopee) and can be longer for telco sign-ups. Confirmed cashback can be withdrawn via PayNow to a linked Singapore bank account. Check the individual merchant page on shopback.sg for the current confirmation window.

Is there a minimum spend to earn ShopBack cashback on phones or accessories in Singapore?

There is no ShopBack-side minimum on most merchants, but individual merchants may exclude specific categories, promo-code use, or gift-card purchases from the qualifying order value. Cashback is calculated on the eligible portion of the basket. Read the specific terms on Apple Online Store, Amazon SG, Lazada, or Shopee before you assume the full basket qualifies.

Which SG telco has the best sign-on bonus for switching in Sep-Oct 2026?

Sep-Oct 2026 sign-on bonuses across Singtel, StarHub, M1, and Circles.Life cluster around 9.9 and 10.10 shopping event windows, with sub-brands GOMO and giga! running the sharpest promos. Typical sign-on incentives include: 2 to 3 months of waived monthly fees on SIM-only plans, S$50 to S$120 bill credit for port-in from a different network, and free data top-ups of 30 to 100GB for the first 3 months. Singtel and StarHub port-in bonuses lean higher (S$80 to S$120) when paired with a broadband bundle refresh. Circles.Life runs promo-code discounts of S$5 to S$10 per month for 12 months on new sign-ups. If you go with Circles.Life or GOMO, go through ShopBack before you sign up and check the live Cashback rate on the store's ShopBack page.

Should I port my number to Singtel, StarHub, M1 or Circles.Life before the 10.10 and 11.11 promo windows in 2026?

Port to Circles.Life if you want the cheapest no-contract SIM-only and are happy with app-only service. Port to Singtel if you already have Singtel broadband or travel often, because the multi-line discount and ReadyRoam day passes do the work. Port to StarHub if the household pays for Disney+ or HBO Max anyway, since the bundle absorbs that cost. Port to M1 if you occasionally burst past your data cap and would rather be throttled than billed. Run the sign-up around 10.10 for the sharpest bonus, and if you choose Circles.Life or GOMO, go through ShopBack before you sign up so part of the cost comes back as Cashback.

What is the cheapest SIM-only mobile plan in Singapore in 2026?

Circles.Life SIM-only plans start at around S$20/month for 50GB with unlimited talk and SMS, no contract. GOMO (Singtel's MVNO sub-brand) and giga! (StarHub's sub-brand) sit in a similar S$18 to S$25/month range. Premium MNO SIM-only plans from Singtel, StarHub, and M1 start at S$25 to S$40/month for similar data buckets, with stronger network priority on congested cells. On ShopBack Singapore, Circles.Life and GOMO are listed stores; go through ShopBack before you sign up and check the live Cashback rate on the store's ShopBack page.

Which Singapore telco has the best 5G coverage in 2026?

Singapore has two nationwide 5G standalone networks: one operated by Singtel, and one jointly operated by StarHub and M1. Both cover underground MRT lines and most malls. Circles.Life is an MVNO that runs on M1's network. For heavy 5G dependence, all three facilities-based operators are consistent in urban Singapore, and most users will not notice a meaningful difference in day-to-day use. If you pick Circles.Life or GOMO, go through ShopBack before you sign up and check the live Cashback rate on the store's ShopBack page.

Is a no-contract SIM-only plan better than a contract bundle in Singapore?

Almost always yes if you are buying your phone outright. Contract bundles subsidise a new phone with a 24-month commitment at S$50 to S$100/month, which works out to S$1,200 to S$2,400 over the contract. The same phone bought outright plus a S$20 to S$30 SIM-only plan costs significantly less. Contracts are worthwhile only for unique handset offers or corporate bundles. Buy the handset outright via shopback.sg/apple-online-store, shopback.sg/amazon, or shopback.sg/lazada-official-store using the ShopBack Chrome extension so ShopBack Singapore Cashback tracks on the qualifying order value.
