Do I need a VPN in Southeast Asia?

Yes, it is highly recommended to have a VPN like NordVPN or ExpressVPN. It helps keep your banking apps secure when using public Wi-Fi in cafes or hostels.

Can I use Uber instead of Grab?

No. Uber does not operate in most of Southeast Asia. Grab is the primary ride-hailing app, though Gojek is a strong alternative specifically in Indonesia.

Should I keep physical cash?

Yes. Even with apps for everything else, many local markets and small vendors are cash-only. Keep the equivalent of $20 in local currency on you at all times.

Essential Apps for Traveling Southeast Asia

To navigate Southeast Asia efficiently, you need Grab for transportation, Agoda for last-minute lodging, and Airalo for cellular data. These three tools will cover 90% of your logistical needs on the ground.

Set up your ride-hailing account. Download Grab before you leave home. Link your credit card in the payment settings to avoid needing exact local cash for every short ride. Note that in some countries like Vietnam or Thailand, it is cheaper and faster than a traditional taxi.
Install a regional eSIM. Use Airalo or a similar service to purchase an eSIM before arrival. This ensures you have data the moment you land, preventing you from fumbling with physical SIM cards at airport kiosks that often overcharge tourists.
Manage bookings with Agoda. While booking.com works, Agoda consistently has better inventory and pricing for the Southeast Asian market. Keep the app updated so you can book a hotel or hostel within 30 minutes of needing one.
Use Google Translate for offline access. Download the language packs for the specific countries you are visiting (e.g., Thai, Vietnamese, Indonesian). This allows you to use the camera translation feature to read menus and signs even when you don't have a signal.
