Vietnam

It comes down to how long you're staying and how much data you use. We sell 14 prepaid Vietnam eSIM plans, starting at $3.30 for a 3GB, 30-day plan.

For a typical one- to two-week trip, the 10GB, 30-day plan at $6.60 comfortably covers maps, ride-hailing, messaging and social media. If you stream, work remotely or share a hotspot, the 50GB plan has the lowest cost per gigabyte at $0.51/GB.

Vietnam eSIM prices start at $3.30 for a 3GB, 30-day plan and go up to $40 for 50GB over 30 days. Bigger plans work out cheaper per gigabyte, down to $0.51/GB. You pay once, upfront: there's no contract, no subscription and nothing billed to your phone account while you're away. Prices are shown in USD.

Multi-country plans that include Vietnam start at $2.20.

It connects automatically to a local partner network in Vietnam, on 4G/LTE or 5G where available. There are 2 plan types to choose from above the plans, each with its own prices.

Vietnam plans don't cut you off. Once the high-speed data is used, you keep a slower connection (128 kbps) until the plan expires, which is enough for messages and email but not video. If you need full speed for longer, choose a bigger plan: the 50GB plan is the largest.

Choose from 7, 15 or 30 days. You have 90 days from purchase to start using the eSIM, so you can buy it well before your trip. Install it at home over Wi-Fi, then switch the eSIM line on when you land in Vietnam, so none of your plan is used before you arrive. Staying longer? Simply buy another plan.

• 1Choose a plan and check out. Your QR code arrives by email straight away.
• 2Before you leave, scan it on your phone: on iPhone go to Settings → Mobile (or Cellular) → Add eSIM; on Android go to Settings → Connections → SIM manager → Add eSIM. Menu names vary by model.
• 3When you arrive in Vietnam, select the eSIM for mobile data and turn on data roaming for that line.

If data doesn't start within a few minutes, restart your phone and check that roaming is on for the eSIM.

Vietnam-only plans work inside Vietnam. If your trip continues to Thailand, Singapore, Indonesia or Malaysia, a multi-country eSIM saves you buying a second one:

• SG, MY, TH, VN, ID: 5 countries, from $2.20
• Asia 11 (Tik Tok): 11 countries, from $4.40
• ASIA 12: 12 countries, from $2.20
• ASIA 22: 22 countries, from $3.30

Switch to “Multi-country” above the plans to compare them.

The Vietnam eSIM is data-only, so it doesn't come with a local phone number or SMS. Anything that runs over data works as normal: WhatsApp, iMessage, FaceTime, Messenger and other calling apps. Hotspot (tethering) is supported, so you can share data with a laptop or a travel companion. Keep your home SIM switched on if you need calls or bank SMS codes, but turn off data roaming on it to avoid your home carrier's charges.

Most phones released since 2019 support eSIM, including iPhone XS/XR and newer, Google Pixel 3 and newer, and Samsung Galaxy S20 and newer, as well as eSIM-capable iPads and tablets. Your phone also needs to be carrier-unlocked. To check, open Settings and look for “Add eSIM” under Mobile/Cellular on iPhone, or SIM manager on Android.

An eSIM is ready before you fly: no searching for a SIM shop at the airport, no ID or registration, and no tiny SIM card to lose. Your home SIM stays in your phone, and you're online the moment you land to book a ride, check maps or message home. Prices are fixed upfront from $3.30, so there's no roaming bill waiting when you get back.
