How to get a Hoi An SIM Card: 3 Steps to stay connected
Staying connected in Hoi An makes it easier to use Grab, navigate the Old Town, translate menus, and keep in touch while travelling. A local Hoi An sim card takes only a few minutes to set up, while an eSIM can be arranged before you leave home. Let’s explore the 3 steps to choosing and using a Hoi An SIM card.
Getting a Hoi An SIM Card: 3 Steps at a Glance
| Step | What to do | Key point |
| 1 | Choose SIM or eSIM | eSIM if your phone supports it; physical SIM if it doesn’t, or if you want a local number |
| 2 | Choose where to buy | An official carrier store, not just any shop selling SIMs |
| 3 | Bring your passport | Required by law, but the staff handle the actual registration for you |
Step 1: eSIM vs. physical SIM – which one do you actually need?
Vietnam’s three main carriers: Viettel, VinaPhone, and MobiFone, offer tourist packages for short stays, typically lasting 7, 15, or 30 days with a set amount of 4G/5G data.
| Option | When to choose it | Key things to know |
| Vietnam eSIM | Your phone supports eSIM and you want to set everything up before flying | iPhone XR and newer and Samsung Galaxy S20 and newer generally support eSIM. Check your exact model before buying |
| Physical SIM | Your phone does not support eSIM or you want a Vietnamese phone number | Useful for Grab, hotel bookings, and SMS verification. Buy and register it at an official carrier store if possible |
| Dual SIM | Your phone supports two SIMs and you want to keep your home number | Keep your home SIM for banking OTPs and important texts while using the Vietnamese SIM for mobile data. Turn off data roaming on your home SIM to avoid unexpected charges |
Some older phones may work with an eSIM-compatible physical SIM, but setup can be more complicated than using a regular physical SIM. Tourist SIMs are temporary, with numbers typically deactivated after the package expires, often within 30-60 days.
Best SIM card for Hoi An and Da Nang coverage
Coverage rarely matters in central Hoi An itself, the Old Town, An Bang Beach, and Cua Dai are all well served by every carrier. It starts to matter once you head toward Ba Na Hills, the Hai Van Pass, or the rural roads out toward Tra Que Village and beyond. Choosing the best sim card Vietnam travel ensures reliable service on those routes.
| Network | Best for | Coverage notes |
| Viettel | Trips beyond the city, Ba Na Hills, Marble Mountains, the road between Da Nang and Hoi An, Hue | Consistently rated the strongest and most stable network in this region; a Hoi An forum Destination Expert specifically recommends it for rural coverage |
| VinaPhone | Old Town, city-based stays | Strong urban 5G, and tourist packages often include a local phone number |
| MobiFone | Short, city-only trips | Solid in central Hoi An and Da Nang, weaker if you’re venturing further out |
Our practical take: if your Hoi An trip includes Ba Na Hills, the Hai Van Pass, or Hue, Viettel is the safer pick for more consistent coverage beyond the city. For itineraries focused on Hoi An Ancient Town and nearby beaches, VinaPhone and MobiFone are generally sufficient when selecting a Vietnam sim card for tourists.

Step 2: Choose where to buy a SIM in Hoi An
Most of Hoi An’s phone shops cluster along Ly Thuong Kiet Street, a few minutes’ walk from the Old Town. A few specific, verified addresses worth knowing for your Hoi An sim card:
- Viettel Store: 211 Ly Thuong Kiet, Cam Pho Ward, open until roughly 9:30 PM
- Viettel Store: 483 Cua Dai (on the road toward the beach), Son Phong Ward, open until around 9 PM
- VinaPhone / The Gioi Di Dong: corner of Hai Ba Trung and Ly Thuong Kiet: the road into town from Da Nang, a couple of blocks north of the Old Town; specifically recommended by a Hoi An Destination Expert on TripAdvisor for good service
- Another VinaPhone branch: 576 Hai Ba Trung, Cam Pho Ward: Mon-Sat 7:30 AM-6:00 PM, Sunday shorter hours (8:30-11:30 AM and 1:30-4:30 PM)
How to find a store yourself, if you’d rather double-check: search “Viettel Store,” “VinaPhone,” or “MobiFone” directly on Google Maps rather than walking into the first shop you see with a carrier logo in the window. This pulls up the actual official branches nearest you, with recent reviews, photos, and even Street View, so you can confirm it’s a real carrier branch and not just an independent phone shop reselling SIMs at a markup. If possible, bring a Vietnamese-speaking guide or a local friend along, especially if you’re unsure about the registration process or the specific package details being offered for a Vietnam sim card for tourists.
One mistake worth avoiding:
- Some sellers may upsell “beautiful” phone numbers with repeating or lucky digits at a higher price. For a tourist SIM, simply ask for a standard package and confirm the total price before paying.
- If a seller says a passport is not needed, treat it as a red flag and go to an official carrier store instead. Your SIM should be registered properly under your name.
Alternatively, you can buy or replace a SIM at independent shops displaying signs such as “Exchange SIM, Card,” but check the registration, activation, data package, and total price first. Da Nang International Airport also has Viettel, VinaPhone, and MobiFone kiosks in the arrivals area, although airport SIMs may cost more than buying a similar package in Hoi An.
How much does a Hoi An SIM card cost?
For most travelers, a tourist SIM or eSIM runs 100,000-250,000 VND for 10-30 days, depending on carrier, data allowance, and whether calling minutes are included when buying the best sim card Vietnam travel.
| Network | Example package | Validity | Price |
| MobiFone | 50GB, 70 domestic minutes | 10 days | ~150,000 VND |
| 150GB, 200 domestic minutes | 30 days | ~250,000 VND | |
| VinaPhone | 8GB/day | 30 days | ~155,000 VND |
| Viettel | Data plans vary | 7-30 days | From ~60,000 VND |
A few questions you can ask before paying:
- Does the quoted price include the SIM, activation, and the data package, or just one of those?
- Is the data allowance a total (like “150GB”) or a daily reset (like “8GB/day”)? The two behave very differently on a two-week trip.
- Does “unlimited data” mean unlimited at full speed, or does it throttle after a daily cap?
For most 10-30 day trips, the Viettel 5G150T package is a good all-round option at 150,000 VND for 30 days with 5GB/day. If you’re staying for only a week, the 5G60H package costs 60,000 VND for 7 days and provides 15GB in total.

Step 3: Registering your SIM – bring your passport, that’s it
This part isn’t optional, and it’s worth understanding why. Vietnam significantly tightened SIM registration rules after the Ministry of Information and Communications identified over 12 million pre-activated, improperly registered SIMs in a 2016 crackdown, eventually deactivating more than 11 million of them. Decree 49/2017 formalized the requirement: subscriber information, including a photo of the registrant, must be checked and recorded before any SIM is activated (Source: Tuoi Tre News).
The good news is that this doesn’t mean paperwork for you. At any official carrier store, staff handle the entire registration process at the counter, you hand over your passport, they enter your details into the system, insert or activate the SIM, and test that it connects before you leave. The whole thing typically adds no more than five minutes to the purchase of your Hoi An sim card.
What to actually do:
- Bring your original passport: not a photo of it, the physical document.
- Register the SIM in your own name: rather than accepting one that’s already registered to someone else (a common shortcut some sellers offer that leaves you without recourse if it’s later flagged).
- Test the SIM before leaving the counter: make a call or load a webpage to confirm it’s actually active.
A properly registered SIM from day one is far less likely to cause problems later, while a cheap pre-activated SIM can leave you without service mid-trip if its registration gets flagged. Opting for an official Vietnam sim card for tourists avoids these issues.
Stay connected for the rest of your Hoi An trip
Once your SIM is sorted, the rest of the trip gets a lot easier – checking the best time to visit Hoi An for your remaining days, navigating to dinner, or confirming a booking on the go. It’s also worth having a look at what a realistic daily budget looks like once you’re online and can actually compare prices as you go.

The resort has 135 rooms and villas across eight categories, with options ranging from 51 m² Deluxe Rooms to the 130 m² Two-Bedroom Pool Villa. Its front desk can also point you to the nearest official carrier store if you’d rather sort out your SIM after checking in.
Getting around is straightforward too. Bliss provides complimentary bicycles for short local trips, while its free shuttle bus runs to Hoi An Ancient Town, making it easier to combine a beach stay with time in the historic centre without relying on a motorbike or taxi for every outing.
And when you are not exploring, there is plenty to do back at the resort. You can spend a slower afternoon by the 55 m oceanfront infinity pool, book a treatment at Ngoc Linh Spa, join a yoga, Tai Chi or breathing session, or have dinner at Binh Minh Restaurant before heading up to the Rooftop Bar. The reading and game room, gym, Himalayan salt-rock sauna and steam room also give you options on rainy days or when you simply want a break from sightseeing.
