Best Mobile Plan Deals Singapore (2026): Cheapest SIM-Only, Postpaid & Prepaid Plans

Why SIM-Only Is Almost Always Cheaper

A SIM-only plan strips out the phone subsidy that inflates traditional contract plans. You bring your own device and pay only for the service — data, calls, and SMS. The savings are significant: a comparable SIM-only plan typically costs S$10–30 less per month than its contract equivalent, adding up to S$240–720 over a 24-month period.

Singtel SIM-Only Plans

Singtel's SIM-only range starts with their XO Plus plans, offering competitive pricing on Singapore's most established network:

• SIM-Only 12GB: S$18/month — 12GB data, 150 mins talktime, unlimited SMS. No contract.
• SIM-Only 30GB: S$28/month — 30GB data, 300 mins talktime, unlimited SMS.
• SIM-Only 60GB: S$38/month — 60GB data, unlimited talktime and SMS.
• SIM-Only Unlimited: S$48/month — truly unlimited data (no speed cap), unlimited calls and SMS.

Singtel often runs sign-up promos giving bonus data (typically +10–20GB free) for the first 12 months. Check the Singtel app for current bonus data offers.

StarHub SIM-Only Plans

StarHub's SIM-Only plans are competitive and frequently include entertainment perks like Disney+ or Apple TV+ subscriptions:

• SIM-Only 15GB: S$18/month — 15GB data, 100 mins talktime. Includes caller ID.
• SIM-Only 30GB: S$25/month — 30GB data, 200 mins talktime.
• SIM-Only 80GB: S$35/month — 80GB data, unlimited talktime and SMS. Often bundled with Disney+ Basic.
• SIM-Only Unlimited: S$45/month — unlimited data, unlimited calls and SMS.

StarHub regularly offers first-month-free promotions for new SIM-only signups. Their “Happy Roam” add-on (S$5/day in ASEAN) is among the cheapest roaming options for frequent travellers to Malaysia, Thailand, and Indonesia.

M1 SIM-Only Plans

M1 positions itself between the premium telcos and budget MVNOs, with simple, no-fuss SIM-only plans:

• SIM-Only 10GB: S$15/month — 10GB data, 100 mins talktime.
• SIM-Only 25GB: S$22/month — 25GB data, 200 mins talktime, unlimited SMS.
• SIM-Only 50GB: S$32/month — 50GB data, unlimited talktime and SMS.
• SIM-Only Unlimited: S$42/month — unlimited data, unlimited calls and SMS.

M1 frequently offers “double data” promotions, turning a 25GB plan into 50GB for the same price. These promos run quarterly and are worth waiting for if your current plan isn't expiring urgently.

Circles.Life

Circles.Life runs on M1's network and has been Singapore's most popular MVNO since launching in 2016. Their app-first approach means no contracts, no hidden fees, and instant plan changes:

• Basic 20GB: S$18/month — 20GB data, 100 mins talktime, unlimited SMS.
• Standard 50GB: S$23/month — 50GB data, 200 mins talktime, unlimited SMS.
• Power 100GB: S$28/month — 100GB data, unlimited calls and SMS.
• Unlimited: S$33/month — truly unlimited data, unlimited calls and SMS.

Circles.Life is known for aggressive promo codes — new users can often get S$10–20 off their first 3 months by using referral codes or seasonal promotions posted on deal forums.

GOMO by Singtel

GOMO is Singtel's own budget sub-brand, running on the full Singtel network with identical coverage and speeds. It's the simplest MVNO option in Singapore:

• GOMO 20GB: S$15/month — 20GB data, 200 mins talktime, 200 SMS. No contract.
• GOMO 50GB: S$25/month — 50GB data, unlimited talktime and SMS.
• GOMO Unlimited: S$30/month — unlimited data, unlimited calls and SMS.

GOMO often includes free roaming data in Malaysia and Indonesia (typically 1GB/day) as a permanent perk. Since it's backed by Singtel, network reliability and 5G access are on par with Singtel's mainline plans.

Other MVNOs Worth Considering

• Vivifi: Runs on StarHub's network. Plans from S$10/month for 8GB. Known for cheap add-on data boosts (S$3 for 5GB). Good for light users who occasionally need extra data.
• CMLink: China Mobile's Singapore subsidiary, running on StarHub's network. Plans from S$12/month for 15GB. Particularly popular with Chinese-speaking users for their competitive China roaming packages.
• Zero1: Runs on Singtel's network. Unlimited data from S$29.90/month. Known for no-contract, no-frills unlimited plans.
• TPG: Australia-based telco with their own infrastructure in Singapore. Plans from S$10/month for 20GB. Competitive pricing but smaller network footprint in some underground areas.

Unlimited Data Price Comparison

True unlimited data plans (no speed throttling, no hidden fair-use caps) have become increasingly competitive in Singapore. Here's how the major providers stack up:

• GOMO Unlimited: S$30/month — best value unlimited plan on Singtel's network.
• Zero1 Unlimited: S$29.90/month — cheapest unlimited plan overall, runs on Singtel network.
• Circles.Life Unlimited: S$33/month — unlimited on M1 network with app-based management.
• M1 Unlimited: S$42/month — premium unlimited with 5G included.
• StarHub Unlimited: S$45/month — includes Disney+ Basic subscription.
• Singtel Unlimited: S$48/month — premium tier with full Singtel perks and 5G.

For most users, GOMO or Zero1's unlimited plans at around S$30/month offer the best bang for buck. The premium telco unlimited plans (S$42–48) are worth it only if you value 5G access, bundled entertainment, or premium customer service with physical stores.

Watch Out for “Unlimited” Fine Print

Some plans advertised as “unlimited” actually throttle speeds after a certain usage threshold (e.g., speeds drop to 1Mbps after 100GB). Always check the fair-use policy. True unlimited plans with no throttling are explicitly marketed as “no speed cap” or “truly unlimited” in Singapore.

Singtel Family Plans

Singtel's XO Plus family add-on lets you add supplementary lines at reduced rates. The main line pays the standard plan price, and each additional line costs S$10–18/month with its own data allocation (typically 10–20GB per supplementary line).

• 2 lines: From ~S$38/month total (S$20 main + S$18 supplementary) for 42GB shared.
• 3 lines: From ~S$53/month total for 60GB shared.
• Savings vs individual: S$5–12/month per additional line compared to separate SIM-only plans.

StarHub Family Plans

StarHub's family bundle is their strongest value proposition. Add up to 5 supplementary lines to a main plan with shared data:

• Family add-on: S$8/month per additional line with 10GB data each.
• Shared data pool: Unused data from the main plan is pooled across all family lines.
• Family entertainment: Disney+ family subscription can be shared across all lines for a single S$4.98/month add-on.
• Savings vs individual: A family of 4 saves roughly S$30–50/month compared to separate plans.

M1 SharePlan

M1's SharePlan is straightforward: choose a main plan and add supplementary lines for S$10/month each. All lines share the main plan's data pool. It's less feature-rich than Singtel or StarHub but competitive on pricing for no-frills families.

MVNO Family Options

Most MVNOs don't offer formal family plans, but you can achieve similar savings by signing up multiple individual lines under one account. Circles.Life offers a “Refer a Friend” bonus (S$20 off for both referrer and referee) which effectively acts as a family onboarding discount.

Singtel hi! Prepaid

Singtel hi! is Singapore's most widely available prepaid SIM, sold at 7-Eleven, Cheers, and Singtel stores. Key options include:

• hi! Tourist SIM: S$15 for 100GB valid 7 days — best value for short-term visitors.
• hi! Data Plan: S$10 for 10GB valid 30 days, auto-renew available.
• hi! Unlimited: S$30 for unlimited data valid 30 days.

StarHub Prepaid

• Happy Prepaid: S$8 for 8GB valid 30 days. Top up at any 7-Eleven or online.
• Travel SIM: S$12 for 50GB valid 7 days — includes ASEAN roaming data.

M1 Prepaid

• M1 Prepaid SIM: S$10 for 12GB valid 30 days.
• Tourist Pass: S$15 for 100GB valid 14 days — popular with longer-stay tourists.

When Prepaid Makes Sense

Prepaid is rarely the cheapest option for regular users — SIM-only postpaid plans almost always offer better per-GB pricing. However, prepaid shines for:

• Tourists: No contract, no credit check, buy and use immediately.
• Secondary devices: Tablets, smartwatches, or backup phones that don't need a monthly plan.
• Children and elderly: Controlled spending with no risk of bill shock.
• Temporary needs: Short-term workers, students on exchange, or event-specific connectivity.

5G Coverage Status in Singapore

As of 2026, Singapore has near-complete outdoor 5G coverage from both Singtel and StarHub. M1 (partnered with StarHub on 5G infrastructure) also offers extensive coverage. Indoor 5G penetration continues to expand, with most shopping malls, MRT stations, and commercial buildings now covered.

Do You Need a 5G Plan?

For most everyday tasks — social media, messaging, video calls, and standard streaming — 4G speeds are more than sufficient. 5G shines for:

• 4K video streaming: Consistently smooth at 300–700Mbps vs 4G's 30–100Mbps.
• Large file downloads: Download a 2GB file in under 30 seconds.
• Cloud gaming: Low-latency gaming on mobile via services like Xbox Cloud Gaming.
• Hotspot for laptop: 5G can replace home broadband for some users, with speeds rivalling fibre.

5G Plan Pricing

The 5G premium has shrunk significantly since its launch. Most telcos now include 5G access in their mid-to-high tier SIM-only plans at no extra charge. Budget MVNOs like GOMO and Circles.Life are beginning to include 5G in selected plans as well. As a general rule, any SIM-only plan above S$25–30/month from a major telco now includes 5G access.

1. Switch to SIM-Only

If you're still on a 24-month contract, switch to SIM-only when it expires. The phone subsidy in contract plans typically adds S$15–25/month to your bill. Buying a phone outright (or on interest-free instalments via credit card) and pairing it with a SIM-only plan is almost always cheaper over 24 months.

2. Right-Size Your Data

Check your actual data usage in your phone's settings (Settings > Mobile Data on iOS, Settings > Network > Data Usage on Android). Most people overestimate their needs. If you consistently use under 10GB, don't pay for a 50GB plan. The savings from downsizing can be S$10–20/month.

3. Stack with Cashback Credit Cards

Pay your monthly mobile bill with a cashback credit card to earn 1.5–5% back. Cards like the POSB Everyday Card (5% on telco bills) or UOB One Card (up to 10% with conditions) can shave S$2–5 off your effective monthly cost. You can compare cashback credit cards on SingSaver to find the best match for your telco bills. Set up auto-billing for convenience.

4. Use Referral and Promo Codes

MVNOs like Circles.Life and GOMO regularly offer referral bonuses (S$20–30 for both parties) and seasonal promo codes. Before signing up, search for active promo codes on WhyNotDeals — we track current promotions across all Singapore telcos.

5. Negotiate at Renewal

If you're with a major telco and your contract is ending, call their retention team before switching. Retention offers often include bonus data, waived monthly charges for 1–3 months, or discounted add-ons not available to new customers. The threat of porting to an MVNO gives you leverage.

6. Consider an MVNO

MVNOs like GOMO, Circles.Life, and Zero1 use the same networks as the big three telcos but charge 20–40% less. The trade-off is online-only support and no physical stores. For most users who never visit a telco shop anyway, this is a painless way to save S$10–20/month.

7. Bundle with Broadband

Singtel, StarHub, and M1 all offer discounts when you bundle mobile plans with home broadband. Typical savings are S$5–15/month on the mobile plan when combined with a fibre broadband subscription. If you're already with the same provider for broadband, ask about bundle discounts.

What is the cheapest mobile plan in Singapore in 2026?

The cheapest mobile plans start from around S$10/month for SIM-only plans with 8–10GB data. MVNOs like Circles.Life, GOMO (by Singtel), and CMLink offer the most competitive entry-level pricing. Prepaid plans from Singtel hi! or StarHub Prepaid start from S$5 for short validity periods.

Should I choose SIM-only or a contract plan?

SIM-only plans are almost always cheaper. A 24-month contract bundles a phone subsidy into your monthly bill, making the total cost higher. If you already have a phone or prefer to buy one outright, SIM-only plans save S$10–30/month compared to equivalent contract plans.

Which telco has the best coverage?

All three major telcos (Singtel, StarHub, M1) have near-complete 4G/5G coverage across Singapore. MVNOs like Circles.Life and GOMO piggyback on these networks, so coverage is identical to the host network. For most users, coverage differences are negligible.

Are MVNO plans reliable?

Yes. MVNOs use the same physical networks as the big three telcos. Circles.Life runs on M1's network, GOMO uses Singtel's network, and Vivifi uses StarHub's network. Call quality, data speeds, and coverage are essentially the same. The main trade-off is online-only customer support.

How much data do I need?

Most Singaporeans use 5–15GB of mobile data per month. If you primarily use WiFi at home and work, 10GB is more than enough. Heavy users who stream video or use hotspot frequently should consider 30–50GB plans. Unlimited plans (S$25–35/month from MVNOs) make sense above 50GB usage.
