Hanoi eSIM questions
How much does an eSIM for Hanoi cost?
Plans start at $1.27 for 500 MB · 7 days. Unlimited daily data costs $1.40 a day (the first 500 MB each day at high speed, then 512 Kbps under the fair use policy). Prices are in US dollars and include everything: no roaming fees, no subscription.
Does the eSIM work on Ha Long Bay?
Near the coast and the main cruise routes, yes. Deeper into the bay and in the caves it drops, which is the same on any network; the boats have their own Wi-Fi for the evening.
Can I use the same plan in Hanoi and Ho Chi Minh City?
Yes. A Vietnam plan covers the whole country, so the flight south, the train or a stop in Da Nang and Hoi An on the way all run on the one eSIM.
