GigSky eSIMs for Vietnam in 2026

MobiFone, Viettel Mobile and Vinaphone are the operators GigSky lists for Vietnam, giving several named networks to fall back on when one is thin outside the cities. Its traffic breaks out in the United States of America, so the round trip to Vietnamese services is longer; video calls and gaming may feel that, while maps, messaging and browsing largely will not, and websites will see a US IP address. 5G is the fastest technology it lists here, but this is not a guarantee. With a large range of plans, sizing the allowance is the main choice, and GigSky does not say whether tethering is available, so check before relying on a laptop connection.
