The options for mobile internet and calling

There are three options for making phone calls and using mobile internet in Thailand: roaming with your own SIM card, a local Thai SIM card, or a prepaid eSIM for Thailand. Roaming is usually expensive. Due to roaming charges outside Europe, travellers are often faced with high bills for using their current subscription in Thailand. It is mainly the data costs that add up. Simple activities such as WhatsApp, navigation and email become unexpectedly expensive. To avoid this, choose a local solution so that you can make cheap calls and use the internet in Thailand. eSIM is ideal for modern smartphones: it is activated via a QR code that you receive by email and no physical card is required. There are several data bundles available, tailored to your usage and travel duration. Furthermore, many bundles include the option for hotspot and tethering, so you can also use mobile Wi-Fi in Thailand.

How to arrange it online in advance

Order your SIM card or eSIM online. You will receive the eSIM Thailand by email. The physical prepaid SIM card Thailand will be delivered to your home free of charge. You can also pick it up in person and receive expert help with installation. This way, everything is taken care of before you leave for Thailand and there is no stress upon arrival. This solution is also suitable for business travellers who can choose bundles with unlimited internet anywhere in Thailand. It is also beneficial for families because with the eSIM Thailand, the unlimited data can be shared via hotspot or MiFi.
