Questions people ask about a Hoi An eSIM
Does a Vietnam eSIM work in Hoi An?
Yes. A Vietnam eSIM runs on Vietnam’s own networks (Viettel Mobile, Vinaphone, MobiFone), so the same plan works in Hoi An and everywhere else those networks reach in the country. There is no separate Hoi An plan to buy.

Does one eSIM cover Hoi An and Da Nang?
Yes. A Vietnam eSIM works across the country, so the same plan covers Hoi An, Da Nang, where the nearest airport is, and the rest of your trip.
Is eSIM available in Vietnam?
Yes. NUM’s Vietnam eSIM runs on Viettel Mobile, Vinaphone, MobiFone. Your phone has to take an eSIM and be unlocked: dial *#06# and look for an EID number.
Do I need to buy a SIM card at Da Nang International Airport?
No. Install the eSIM at home on wifi and switch it on as the plane lands at Da Nang International Airport (DAD). There is no SIM counter to find and no queue.
How much data do I need for Hoi An?
For a week of maps, rides, messages and photos most people use about 3 GB; for two weeks about 5 GB; for a month of social and video, 10 GB or more.
Will I be online when I land in Hoi An?
Install the eSIM at home on wifi, then switch the line on as the plane lands at Da Nang International Airport (DAD). You are online walking off the plane, with no SIM counter and no airport wifi.
Can I use it as a hotspot?
Hotspot works on most plans, so one eSIM can get a laptop or a travel partner online too.
Why does my eSIM show another carrier’s name?
Many travel eSIMs are issued by one carrier and roam on local networks, so your phone can show the issuing carrier’s name while your data runs on a local network. Keep data roaming on for the eSIM.
Will it work on my phone?
Dial *#06# on the phone you’re taking. If you see an EID number, it takes an eSIM. Every iPhone from the XR and XS on does, and the SE from 2020, as do Google Pixel 3 and later and Samsung Galaxy S20 and later. The phone must be carrier-unlocked. Not sure? Text PHONE and your model and we’ll check.
When do I install it?
At home, on wifi, before you fly. Then switch it on when you land. Tell us your landing day and we text you the switch-on steps that morning.
Does it come with a phone number?
No. It’s a data-only eSIM. WhatsApp, LINE, iMessage and FaceTime all work over it, and your home number can stay on for calls and codes.
What if it doesn’t work?
If we can’t issue your eSIM, we refund you in full. If it won’t install or connect, text us and we help you get connected.
