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

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'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'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.

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.

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.
