Southeast Asia Travel Data Guide: Thailand, Vietnam, Indonesia

Southeast Asia Network Overview

4G coverage in Southeast Asian countries is already very high. Urban areas have near-complete coverage, while islands and remote areas may have blind spots.

Country Recommendations

Thailand 🇹🇭

Thailand has excellent 4G coverage. Bangkok and popular tourist cities have fast speeds. A 7-day 3GB plan (about $5) is sufficient for daily use.

Vietnam 🇻🇳

Vietnam has decent speeds for Southeast Asia. Hanoi and Ho Chi Minh City have good coverage. Choose a plan with more data as many apps load frequently.

Indonesia 🇮🇩

Bali and Jakarta have good coverage, but remote islands (like Komodo) may have weak signal. Download offline maps beforehand.

Southeast Asia eSIM Tips

• Install eSIM before departure to avoid scrambling upon arrival
• Enable data compression (like Chrome Lite mode) to save data
• Video calls and streaming consume lots of data — use WiFi when possible
