Amigo eSIM vs 4S eSIM
— which eSIM is better?
Amigo and 4S eSIM occupy different niches: Amigo is a newer aggregator spreading across popular destinations globally, while 4S eSIM is a deep Asia specialist with direct relationships to the region's dominant carriers. For an Asia-only trip, 4S eSIM's network access is hard to beat; for destinations outside Asia, Amigo is the more relevant option of the two.
Verdict
4S eSIM wins decisively for Japan, Thailand, Singapore, Indonesia and South Korea on direct carrier access; Amigo is the better fit for popular destinations outside Asia where 4S eSIM has no presence.

Network routing — what's actually different
4S eSIM's direct agreements with NTT Docomo/SoftBank, AIS, SingTel/StarHub, Telkomsel and KT/SKT mean it sits on the primary network in each of its core markets — a structural advantage that an aggregator model like Amigo's can't replicate without years of carrier negotiation. Amigo's strength is breadth and pricing flexibility in markets where it has signed partnership deals, which currently skew toward popular non-Asia destinations.

Which is cheaper for Southeast Asia?
4S eSIM, generally — its direct carrier agreements in Thailand, Indonesia and Singapore mean lower prices ($6+) and no throttling on premium plans, compared to Amigo's variable-throttle plans from $8.
Is 4S eSIM only useful for Asia trips?
