problem is at $14.80, Eight's 5G plan is more expensive than the competition
maxx, circles, zym, z1 all have 5G plans around $10 or lower
(I don't rate Simba as proper 5G, so not included)
Zym/Z1/VIVIFI/CMLink have no pure 5G plans at around S$10. Their 5G plan is at around S$15 per month. But they do have 4G plan with 180 days or half year 5G trial at around S$10 (Zero1 at S$12).
M1 Maxx --> S$12 per month. They used to offer 5G for the S$10 plan but they have since removed 5G from new M1 Maxx S$10 plan users. Only existing M1 Maxx S$10 5G users will get 5G.
CL --> this one is interesting, they have so many promotion codes and indeed some of the promotion codes are very good.
Indeed I will not count SIMBA as having proper 5G now.
Main benefits for eight compared to ST MVNOs and M1 M1 Maxx may be the roaming benefits, especially the free roaming voice. ST MVNOs are catching up in terms of roaming data bundle but tough to offer free roaming voice because of Singtel. Still Zym Roam Guard (10 minutes free) is the right direction.
Down the road, eight will have more promotions for the S$14.8 and S$18 5G plans, much less on eight S$8 and S$11.8 4G plans.

7. I am seeing a "Roam Guard 10 Mins" in my mobile app or bill invoice. What is this?
W.E.F Feb 2026, Roam Guard, a new feature, automatically absorbs the cost of your first 10 minutes of incoming roaming calls each month while you’re overseas to help prevent bill shock; any incoming time beyond 10 minutes and all outgoing roaming calls are charged at standard pay‑per‑use roaming rates.
