eSIM Roamless pour Vietnam en 2026

Roamless names MobiFone as its Vietnam network, so the operator is settled before you choose a plan: the differences here are allowance and validity, not signal. Its fastest stated technology is 5G, an upper limit rather than a promise of what your phone will show. Roamless does not say where traffic breaks out, so the IP location and delay to Vietnamese services are worth checking. With a large range of plans, sizing is the real decision, and buying more data than a fortnight needs is the risk. Top-up is supported, so an exhausted plan can be extended.
