Exploring Thailand requires a reliable internet connection. However, using your European mobile plan abroad can quickly lead to unpleasant surprises. The infamous "roaming charges" (or roaming) can turn a simple Google Maps search into a hefty phone bill on the return trip.
Here are the 4 best strategies to maintain a 4G/5G connection in Thailand without emptying your wallet.
1. The 4 methods to connect without roaming charges in Thailand
Option 1: The international eSIM
An eSIM is a virtual SIM card already integrated into recent smartphones. It allows you to download a Thai data plan online before your departure, without any physical manipulation.
- Benefits : Instant activation upon landing, no administrative procedures on site, retention of your French SIM card (to continue receiving your bank SMS on WhatsApp).
- Disadvantages: Requires a phone compatible with eSIM technology.
Practical tip: For safe travel, discover our Thailand eSIM package with high-speed data tailored to the length of your stay.
Option 2: The local physical SIM card
A classic method is to buy a prepaid SIM card from a Thai operator (AIS, TRUE Move, dtac) in an official store or upon arrival at the airport.
- Benefits : Access to local rates for large volumes of GB.
- Disadvantages: Queues at the airport, the obligation to provide one's passport for legal registration, and the need to remove one's main SIM card (at the risk of losing it).
Option 3: Rely solely on free Wi-Fi
It appears to be the most economical method, but it is the most restrictive and risky in practice.
- Benefits : Free in hotels, cafes and airports.
- Disadvantages: High risk of hacking on open public networks, lack of connection while travelling, and the obligation to download offline maps beforehand.
Option 4: Activate an international option with your French operator
Major operators sometimes offer Escape Passes or America/Asia options.
- Benefits : Maintaining the usual plan without changing any complex settings.
- Disadvantages: High prices compared to the volume of GB granted, and risk of exceeding the plan's limits if the option expires during the stay.
2. Why is eSIM the best strategy for travelling to Thailand?
For tourist stays of 1 to 3 weeks, the eSIM stands out as the number 1 choice for travelers for three key reasons:
- Saving valuable time: You avoid the long queues at Bangkok airport check-in counters after a 12-hour flight.
- Increased security: No need to open your phone's SIM card slot on a corner of a table and risk losing your French SIM card.
- Dual SIM active: You use the eSIM only for low-cost mobile data, while keeping your main line open to receive emergency calls or validation SMS.

How do I disable roaming on my phone before leaving?
In your smartphone settings (section Mobile network Or Cellular data), simply disable the option «"Data held abroad"» Or «"Data roaming"» of your primary SIM card. This blocks any unwanted data usage by your original operator.
