Yes, your SouthESIM will typically offer strong 4G/LTE connectivity on popular tourist islands! Whether you're soaking up the sun in Bali, exploring the beaches of Phuket, or diving in Palawan, you'll find reliable service in towns, resorts, and popular areas. Keep in mind that signal strength might naturally vary in very remote spots or during boat trips between smaller islands. But for most of your island adventures, you'll be well-connected.

When you're traveling between countries, say from Singapore to Malaysia, your phone will automatically detect and connect to a local partner network in the new country.

These apps are essential for a smooth travel experience in cities like Kuala Lumpur and Ho Chi Minh City, and we make sure you can use them worry-free.
Not at all! Your SouthESIM is a data-only service, meaning it provides internet access without changing your primary phone number. You can continue to use WhatsApp, Line, or any other messaging app with your original number, keeping all your chats and contacts intact. If any app asks if you want to update your number, just decline, and you'll be all set to keep communicating as usual while enjoying your travels with SouthESIM.

We recommend topping up before you completely run out, ensuring a continuous connection as you explore amazing places like Rio de Janeiro or Chiang Mai.
