Using your eSIM in Vietnam
Vietnam is a moving trip — Hanoi to Hoi An to Ho Chi Minh City over three weeks is normal — and a plan that works everywhere beats buying a SIM in each stop. The plans on this page list MobiFone, Vietnamobile, Viettel Mobile and Vinaphone as the networks the eSIM can attach to. Coverage is strong in the two big cities and along the coast.
Ride-hailing is the normal way around the cities and needs a live connection to book, not just to look. Some plans here include 5G (11 of 14); the others are 4G, so check the speed line on the plan if it matters to you.
Longer itineraries usually favour the daily plans over one fixed bundle: a steady amount each day, no large purchase up front. Sizes run from 500 MB over 1 day at $3.28 to 50 GB over 180 days at $89.54. Every plan here can be topped up from the app without reinstalling anything.
Setup before you go: scan the QR on wi-fi, set data roaming on for the Num line, off for your home line, leave the APN automatic. Validity begins on the first connection in Vietnam. This plan fits a two-to-four-week trip down the length of the country.

Questions about Vietnam
How much does an eSIM for Vietnam cost?
Plans start at $3.24. The table on this page shows current prices — 14 options ranging from short trips to month-long stays. These are the prices you pay in the app; there are no separate activation or delivery fees.
Will my phone work with a Vietnam eSIM?
Most iPhones from the XR and XS onward support eSIM, and the handset must be carrier-unlocked. Check the compatibility page for the full list before you buy.
When does the plan start counting down?
Validity begins when the eSIM first connects to a network in the coverage area, not when you buy it. You can install it before you travel and it will wait until you land.
Can I keep my normal number while using it?
Yes. The Num eSIM runs alongside your existing SIM, so calls and texts on your usual number keep working while data runs over the travel plan. Turn your normal line's data roaming off to avoid a roaming bill.
Can I add more data if I run out?
Yes — reloadable plans can be topped up from inside the app without buying a new eSIM or reinstalling anything.
Is there an unlimited data eSIM for Vietnam?
Num does not sell unlimited plans for Vietnam. The closest are the daily-allowance plans, such as 500 MB per day, which give a fixed amount each day for the length of the trip. For most travellers the fixed bundles, from 500 MB to 50 GB, are better value.
Which networks does a Num Vietnam eSIM use?
It connects to MobiFone, Vietnamobile, Viettel Mobile and Vinaphone and picks the strongest available network automatically. 11 of the 14 plans support 5G; the rest run on 4G/LTE.
Do I get a Vietnam phone number with the eSIM?
No. Num eSIMs are data-only. Your own number stays active on your existing SIM for calls and texts, and WhatsApp, iMessage and other messaging apps keep working over the eSIM's data. If you need a local number, see our guide to eSIMs with a phone number.
What is the best eSIM for Vietnam?
It depends on how long you stay and how much you use maps and video. On this page the best value per gigabyte is 5 GB per day for 1 day at $6.36 ($1.27); the trip-length picks match a plan to a weekend, a week, two weeks and a month. The comparison page sets Num's prices against Airalo, Saily, Nomad, Simpal, Maya at matched plan sizes, including the sizes where we are not the cheapest.
