Wherever we are planing to travel to, having a working mobile phone in Vietnam is essential. So if you are roaming around Southeast Asia and are wondering if your phone will work there, we are here to answer all of your questions. Specifically, today we will be talking about Vietnam, an incredible destination known for its vibrant culture, rich history, and breathtaking landscapes. From the bustling streets of Hanoi and Ho Chi Minh City to the serene beauty of Ha Long Bay and the terraced fields of Sapa, the country offers an unforgettable experience for every type of traveler.
With a fast-growing digital infrastructure and increasing tourism, staying connected while exploring Vietnam is more important than ever. Whether you’re navigating local markets, booking transport, or sharing your journey online, a reliable mobile connection can make all the difference — and that’s where eSIM technology comes in.
Most modern smartphones will work in Vietnam, especially if you’ve purchased your device in the past few years. The most important requirement is that your phone is unlocked, meaning it isn’t restricted to a specific carrier. Vietnam operates on GSM networks, which are widely supported by the latest devices from major brands like Apple, Samsung, and Google. If you’re planning to use an eSIM, you’ll also need a phone that supports this technology; for example, iPhone XS and newer or recent Google Pixel and Samsung Galaxy phones typically do. While 5G is becoming more available, Vietnam has strong 4G/LTE coverage across most regions, so as long as your phone supports common network bands, you should stay well connected during your trip.
Mobile Roaming in Vietnam
Using mobile roaming in Vietnam is provided by most international carriers. However, it can be expensive depending on your home carrier. While roaming offers the convenience of staying connected without switching SIM cards, many carriers charge high rates for data, calls, and texts when you’re abroad. Some providers offer travel packages or daily roaming passes that lower the cost, but these are still often more expensive than local or eSIM options. Furthermore, coverage through roaming is generally reliable in cities and tourist areas, but service quality may depend on the local partner network your carrier uses. For travelers looking to stay connected affordably, especially for longer stays, alternatives like local SIMs or eSIMs are typically much more cost-effective and flexible.
Here are some examples of roaming rates:
- EE (UK): Approximately $2.25 per minute for calls, $2.25 per minute to receive calls, and $0.75 per text.
- Vodafone (UK): Approximately $0.75 per minute for calls, $0.45 per minute to receive calls, and $0.10 per text.
- O2 (UK): Approximately $2.50 per minute for calls, $2.50 per minute to receive calls, and $0.63 per text.
- Movistar (Spain): Approximately $13.40 per MB for internet, $3.30 per minute to call Spain or local numbers, and $1.30 per SMS.
- Rogers (Canada): Approximately $11.00 per 10 MB for data, $0.95 per text, and $4.00 per minute for calls.
Remember, these values are approximate, and the final price will depend on your carrier and current cellphone plan.
