Frequently asked questions

Gohub eSIM is one of the best eSIM options for Vietnam, with reliable 4G coverage via Mobifone across Hanoi, Ho Chi Minh City, Da Nang, Hoi An, Hue, Nha Trang, Ha Long Bay, and the Mekong Delta. Plans include daily and Call & SMS options, all prepaid and activated via QR code. Rated 4.8/5 by over 500,000 travelers worldwide.

Yes. Gohub eSIM works throughout Vietnam by connecting to Mobifone. Purchase a plan at gohub.com, scan the QR code before departure, and your eSIM connects automatically when your device detects a local Vietnamese network. Coverage is strong in all major cities, along the coastal route from Hanoi to Ho Chi Minh City, and on Ha Long Bay cruise decks, with lighter signal in remote highland areas.

Install the eSIM via Wi-Fi before your trip. On iPhone, go to Settings > Cellular > Add eSIM. On Android, go to Settings > Connections > SIM Manager (Samsung) or Settings > Network & Internet > SIMs (Pixel and others). After arrival, call 900 to complete the required special activation on the Mobifone network. Each plan day resets at 11:59 PM GMT+7 regardless of your install time.

Yes. Gohub eSIM costs far less than standard carrier roaming, which runs $5–$15 per day with most US providers. Gohub Vietnam plans deliver full-speed 4G data via Mobifone up to your daily cap, after which the eSIM stops connecting to the network until the next daily reset at 11:59 PM GMT+7.

A 10–15 day Vietnam trip on the classic North-to-South route needs at least 2–6 GB per day for Google Maps, Grab ride-hailing, food delivery apps, and social media. The 6 GB/day Call & SMS plan over 10 days suits travelers moving between cities daily, while the 3 GB/day plan over 15 days covers longer, slower-paced itineraries including beach and highland stays.

Yes. A Wi-Fi connection is required to download the eSIM profile. Complete this at home before departure. Once the eSIM is installed, call 900 after arrival in Vietnam to complete the special activation required by Mobifone. After that, your Gohub Vietnam eSIM connects without Wi-Fi exactly like any standard mobile data plan.

Yes. Gohub eSIM runs alongside your physical home SIM using your phone's dual-SIM capability. Keep your home SIM active for calls and texts from home while the Gohub eSIM handles Vietnamese data. Turn Data Roaming OFF on your home SIM and ON for the Gohub Vietnam eSIM to avoid unexpected charges.

Gohub eSIM for Vietnam works with all eSIM-capable, carrier-unlocked smartphones — including iPhone XS/XR and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later. Your phone must be network-unlocked; carrier-locked devices will not accept a third-party eSIM. Check Settings > Cellular > Add eSIM on iPhone, or SIM Manager on Android, to confirm support.

Yes. Gohub eSIM via Mobifone maintains strong 4G signal on Ha Long Bay open water, at Lan Ha Bay and Bai Tu Long Bay, and along the Reunification Express train route between Hanoi and Ho Chi Minh City. Signal is excellent at major train stations in Da Nang, Hue, and Nha Trang, though it naturally weakens briefly inside long mountain tunnels on the central Vietnam coastal rail route.

Some plans do. The 6 GB/day Call & SMS plan via Mobifone includes a local Vietnamese phone number ("Local phone number Vietnam"), 100 free on-net minutes, and 100 free on-net SMS messages. Data-only plans such as the 2 GB/day and 3 GB/day options do not include a phone number but fully support WhatsApp, Zalo, and VoIP calls. To check your number, press *0# after activation.
