What Happens When You Land in Vietnam
- 1
Install your eSIM before your trip
Buy an LTE.app Vietnam eSIM and install it on Wi-Fi at home. Takes 2–3 minutes via QR code. Your home SIM stays active and untouched.
- 2
Land at Tan Son Nhat International Airport
After your flight, switch off airplane mode. Go to Settings and enable your LTE.app eSIM line.
- 3
Connect to Viettel, Mobifone, Vinaphone (VNPT)
Your phone automatically connects to Vietnam's LTE network. Hanoi, Ho Chi Minh City, Da Nang, and Hoi An are well covered. Ha Long Bay (Halong) has LTE near the cruise port and on the main bay but may drop in coves. Sapa mountain area has improving coverage. Phu Quoc island is well covered in resort areas.

Maps, messaging, and apps work instantly
Navigation, translation, ride-hailing, and messaging apps all work from the moment you exit the arrivals hall — no queuing, no SIM card swap.
Will my phone work in Vietnam?
Yes. Vietnam uses standard LTE bands compatible with all modern smartphones.
Vietnam's LTE bands (1, 3, 7, 28) match Southeast Asian and global standards. All modern phones work. Viettel has the widest rural coverage including in highland areas. For Ha Giang Loop motorcycle routes and remote northern provinces, Viettel is the best carrier choice.
How much does roaming cost in Vietnam?
Roaming with your home carrier in Vietnam is significantly more expensive than a local eSIM.
US and EU carriers charge $10–20/day for Vietnam roaming. Vietnam has some of Asia's cheapest local data — roaming is exceptionally poor value.
Roaming vs local SIM vs eSIM in Vietnam
Vietnamese local SIM cards are among the cheapest in the world. Roaming is 5–20× more expensive per GB.
Airport SIM kiosks at Tan Son Nhat and Noi Bai offer tourist SIMs for $2–8 for 10–30 GB. This is extraordinary value. An LTE.app Vietnam eSIM installs before landing and is similarly priced, with the advantage of zero airport queuing.
Best internet option for Vietnam tourists
Either an eSIM or airport SIM is excellent. An eSIM on Viettel gives the best rural coverage for northern Vietnam motorbike routes.
Vietnam's north — Ha Giang Loop, Sapa, Mai Chau, and the Ha Giang border region — requires Viettel for any meaningful coverage. Mobifone and Vinaphone have limited rural reach. For adventurous travelers heading beyond the major tourist trail, a Viettel-connected plan is strongly recommended.
LTE coverage and networks in Vietnam
Vietnam uses LTE bands 1, 3, 7, and 28. Viettel has the widest national coverage. Mobifone and Vinaphone (VNPT) compete in urban areas.
Hanoi, Ho Chi Minh City, Da Nang, and Hoi An are well covered. Ha Long Bay (Halong) has LTE near the cruise port and on the main bay but may drop in coves. Sapa mountain area has improving coverage. Phu Quoc island is well covered in resort areas.
Connectivity tips for Vietnam travelers
- →Grab dominates ride-hailing in Vietnam. In cities without Grab, Be is the alternative. Data is essential for both.
- →Ha Long Bay overnight cruise boats typically have Wi-Fi but it is often slow. Your eSIM provides better connectivity when near the shore.
- →Sapa (mountain trekking town) has good LTE in town but signal drops on rice terrace trekking routes.

Frequently asked questions — internet in Vietnam
Is there internet in Ha Long Bay?
Yes, near the cruise port (Halong City). On cruises in the bay, you get LTE near shore and in the main channels. Remote coves and overnight anchorage spots may have limited signal. Most cruise boats have onboard Wi-Fi.
Is there internet in Sapa?
Yes in Sapa town. Viettel provides the best coverage in the Sapa area. Rice terrace trekking routes between villages may have limited signal. Download offline maps before trekking.
Which Vietnamese carrier is best?
Viettel for rural and northern Vietnam coverage. Mobifone is competitive in Ho Chi Minh City and Da Nang. For island destinations (Phu Quoc), both Viettel and Mobifone work well.
Does Grab work in Vietnam?
Yes. Grab is the primary ride-hailing app in HCMC, Hanoi, Da Nang, and Hoi An. Be is the Vietnamese alternative. Both require mobile data.
Is roaming expensive in Vietnam?
Extremely relative to local prices. US carriers charge $10–20/day in Vietnam. A local tourist eSIM for a full week costs $3–8 — making Vietnam one of the worst-value roaming destinations relative to local alternatives.
