5 Best Telco Mobile Plans in Singapore (2026) — Postpaid Compared

Singtel vs StarHub vs M1 vs Circles.Life vs Simba — we compare Singapore's top postpaid mobile plans on price, data, and perks to find the best value for every type of user.

Choosing a mobile plan in Singapore used to be simple — you picked between Singtel, StarHub, and M1. Then MVNOs (mobile virtual network operators) like Circles.Life and Simba turned the market upside down with SIM-only plans offering 100GB+ of data for under $20. Today, the right plan depends less on brand loyalty and more on how much data you actually use, whether you travel, and whether you want a contract.

We compared all five major telcos on price per GB, roaming inclusions, 5G coverage, and real-world customer satisfaction. Here are the best mobile plans in Singapore for 2026 — for heavy data users, budget-conscious SIM-only hunters, and frequent travellers.

Singtel

Singapore's largest telco with the most extensive 5G coverage and strongest overseas roaming partnerships. Singtel's XO plans include generous local data (150GB+), weekly roaming in 8 popular countries, and discounts on Singtel TV. Their network is consistently rated #1 for reliability, especially in underground MRT stations and rural parts of the island. Best for frequent travellers and those who want a premium, full-service telco experience.

StarHub

StarHub's Mobile+ plans bundle local data, free roaming in select countries, and bundled streaming subscriptions (Disney+ or Netflix depending on plan). Their network is a close second to Singtel in reliability and they offer some of the most aggressive recontract rebates in the market. StarHub Go members also get discounted home broadband when bundled. Best for households who want mobile + broadband + streaming in one bill.

M1

M1's Maxx plans punch above their weight with competitive data allowances and one of the best 5G networks in Singapore (they were the first to launch standalone 5G locally). Their Bespoke plans let you customise data, voice, and SMS separately — rare flexibility in the SG market. M1 regularly wins price wars during promo periods and their no-contract SIM-only Sunshine plans are a hidden gem at around $25/month for 150GB.

Circles.Life

The MVNO that first shook up Singapore telcos with its no-contract, app-first approach. Circles.Life offers some of the best value SIM-only plans — their 100GB plan at under $20 is perfect for moderate users, and you can boost data anytime directly from the app without calling customer service. Runs on Singtel's network so coverage is identical to a standard Singtel line. Best for digital natives who want flexibility without locking in.

Simba (formerly TPG)

Singapore's cheapest mainstream telco — Simba regularly offers 200GB+ SIM-only plans at under $20/month, including 5G access. Coverage has improved dramatically since the TPG rebrand and their network now handles standard urban use reliably, though indoor coverage in older HDB buildings can still lag. Best for price-conscious users who don't travel often and want maximum data for minimum spend.

Get a new SIM or port-in and enjoy free plan renewals + freebies worth over S$700 (current islandwide promo). Plans from S$10/month with 5G access + roaming to 60+ countries, no contract.

Frequently Asked Questions

What is the cheapest mobile plan in Singapore in 2026?

Simba (formerly TPG) has the cheapest credible plans, starting at S$10/month with 5G access, 100GB data, and roaming included to 60+ countries. There's no contract, so you can cancel any month. The trade-off is no physical store support — everything is via the Simba app.

Which Singapore telco has the best 5G coverage?

Singtel and StarHub both deployed 5G nationwide first and have the strongest indoor coverage, including in MRT tunnels and shopping mall basements. M1's 5G is similar above ground but slightly weaker in indoor edge cases. Simba and Circles.Life ride on the major networks (M1 and Singtel respectively), so coverage is identical to their host network.

Can I keep my number when I switch telcos in Singapore?

Yes. Number portability is mandatory in Singapore — you keep your existing mobile number when switching providers. The new telco handles the port for you; you just need to provide your existing account details. Porting typically takes 1–3 working days, with a brief blackout period of a few hours.

Are 24-month telco contracts still worth it in Singapore?

Rarely. Contract plans usually bundle a phone discount, but you can buy the phone outright (or via interest-free instalment) and pair it with a no-contract Simba/Circles.Life plan to save more over 24 months. Contracts only make sense if you need flagship phone subsidies you can't otherwise afford.
