On the live Singapore-country ladder, the eligible 10 GB 30-day dest totals this pass are Sim Local $12.75, Ubigi $13, Nomad $14, Saily $15.99, Airalo $16, Yesim $19.51 and GigSky $84.99. Dest's cheapest Singapore-country 50 GB is Nomad 30-day at $31 ATESIM, so the GigSky 180-day out rule stays quiet; GigSky still misses the six because its 10 GB total is $84.99. Dest lists no Roamless, aloSIM or ByteSim Singapore-country SKU. Every ranked 10 GB total is unique, so named-host tiebreak is idle.
Opensignal's Singapore Mobile Network Experience Report for July 2026 (collection 1 April to 29 June 2026) covers M1, SIMBA, Singtel and StarHub. Verified national figures on that report include Singtel Reliability Experience 927 on a 100-1000 scale (SIMBA 909; StarHub 826; M1 818), Singtel Consistent Quality 84.7 per cent of tests (StarHub 78.0; SIMBA 70.7; M1 68.7), StarHub Download Speed Experience 172.7 Mbps (Singtel 164.4; M1 146.6; SIMBA 25.0), M1 and StarHub statistically tied 5G Download about 302.4 to 305.5 Mbps with Singtel about 294.8, StarHub Upload Speed Experience 25.3 Mbps (Singtel 24.2; M1 21.8; SIMBA 6.0), Singtel 5G Upload 34.4 Mbps (StarHub 33.0; M1 32.7; SIMBA 9.2), Singtel 5G Coverage 9.5 on a 0-10 scale (M1 9.0; StarHub 9.0; SIMBA 8.9), all four Time on Network statistically tied 99.3 to 99.5 per cent, and Singtel 5G Availability 79.9 per cent (StarHub 70.0; M1 67.0; SIMBA 31.4). Singtel took Best Network on that report. The report also records nationwide 5G Standalone coverage, with M1 and StarHub finished on the NSA-to-SA move and Singtel still showing a small NSA remainder at collection time. Those scores describe the national MNOs. They do not name a host for any pick.
Dest copy records near-total island coverage on Singtel, StarHub and M1, Singtel's July 2022 standalone 5G coverage mark, and passport registration on local Singtel or M1 tourist plans. Those lines are dest narrative. They are not a shop host. Ubigi Malaysia + Singapore Prepaid rows on dest are multi-country catalogue rows, not a Singapore-country ranking latch.
Singapore sits outside the EU and the EEA, so roam-like-at-home never applies. Storefront prepaid pricing is the Singapore-country rule here; do not invent RLAH.
Sentosa-as-separate, Batam, Johor, Malaysia and Indonesia border latch stay empty as coverage claims unless that shop names the place. Airalo Connect Lah other_info names M1 and Singtel networks in Singapore. Nomad prints an overseas-territory hedge and a catalogue Network for Singapore line. Sim Local, Ubigi, Saily, Yesim and GigSky leave Sentosa, Batam, Johor, Malaysia and Indonesia unnamed as separate coverage on the Singapore-country shops this pass. Do not invent a cross-border latch from Singtel, StarHub, M1 or Simba presence alone.
The dest 10 GB, 30-day country order among the six ranked picks is Sim Local, Ubigi, Nomad, Saily, Airalo, Yesim. Once a plan registers on a Singapore network, top-ups stay inside that provider's app.
A CBD hotel block and a few MRT-heavy days burn data at different rates from a single afternoon on Sentosa. Plan Match at /plan-match turns those trip inputs into a Singapore-country GB total against the live ladder on this page while the size is still open.
