Where to Buy a European Travel SIM?
While traveling through Europe, staying connected is key to making your journey more convenient. One common solution is to use a travel SIM, with two main options: get a SIM in Vietnam before departure or purchase one upon arriving in Europe. Each option has its own set of pros and cons.
1. Purchase a European Travel SIM in Vietnam

Buying a SIM before your trip provides peace of mind, as you can review available plans, choose a reputable provider, and have internet access as soon as you arrive. In Vietnam, European travel SIMs are easily found at mobile stores in Hanoi, Ho Chi Minh City, or on e-commerce platforms like Shopee, Tiki, and Lazada.
One advantage of buying in Vietnam is that you don’t need to provide additional personal documents since the seller has already registered the information. When purchasing in person, all you need to do is choose the right plan, pay, and receive your SIM. If buying online, you'll need to provide your name, address, and phone number, and the SIM will be delivered to your doorstep within a few days. There is a wide variety of SIM cards available, offering different coverage areas, data capacities, and validity periods to suit your needs.
2. Purchase a Travel SIM in Europe

If you haven't purchased a SIM in Vietnam, buying one in Europe is also an option, though there are a few things to keep in mind. SIM booths at airports and major cities are typically operated by networks like Vodafone or Three, but the process can be complicated: you’ll need to provide a passport, a photo, and prices are often 20-40% higher than purchasing in Vietnam.
In the city, you can find SIM cards at convenience stores, supermarkets, or gas stations. In official stores, staff will assist with setup and activation; however, if buying from other retail outlets, you will need to do it yourself. Registering personal information in Europe can also be detailed and sometimes challenging due to language barriers.
Which European Mobile Network Should You Choose?
If you're preparing for a trip to Europe, selecting the right SIM is crucial. Here are some detailed suggestions to help you make the best choice for your journey.

Important Notes for Using European Travel SIM Cards

To ensure a stable and convenient connection during your trip, keep the following key points in mind when using a European travel SIM card:
- A European SIM purchased in Vietnam does not support recharging or international calls, but it is usually much cheaper than buying a SIM abroad.
- If the SIM card doesn't work, contact the provider for assistance. If the SIM is faulty due to manufacturing, you will need to keep the SIM and packaging to receive a refund after inspection.
- It’s recommended to insert and activate the SIM 1-2 days before your trip to ensure it functions correctly. Activation for roaming services can take between 1 hour to 48 hours depending on the internet connection at the destination.
- For eSIM, make sure to scan the code and download it before leaving Vietnam for installation support if needed.
- Download the My3 app to check your balance, remaining data, free call minutes, and text messages.
- If you experience connection issues, check the APN settings on your phone. For iPhone: Go to Settings > Mobile > Mobile Network > APN | For Android: Go to Settings > Connections > Mobile Network > Access Point Names.
A suitable European SIM card is an essential companion for those who love to explore and seek the freedom of independent travel.
