π‘ Pro Tip for Vietnam
Vietnam has excellent 4G coverage with 5G rolling out in major cities. Viettel offers the best nationwide coverage, especially for adventures like the Ha Giang Loop. Coverage is strong in all tourist areas but can be spotty in remote mountain passes. The country is incredibly affordable - street food costs $1-3 per meal. Grab is essential for transportation in cities. Traffic is chaotic - download offline maps before motorbiking. Vietnamese coffee culture is amazing - try egg coffee in Hanoi and coconut coffee in Saigon. Language barrier is real - download Google Translate offline. Bargaining is expected at markets - start at 30-40% of asking price. The country is long and narrow - domestic flights save time between regions. Train travel is scenic but slow. Sleeper buses are an adventure. Each region has distinct cuisine - don't miss pho in the north, bun bo hue in the center, and banh mi in the south. Homestays offer authentic experiences. The war history is important to understand - visit museums respectfully. Beach towns like Da Nang and Nha Trang have strong expat communities. Island paradise Phu Quoc doesn't require a visa for stays under 30 days. SIM registration typically requires passport but eSIM bypasses this. Weather varies dramatically by region and season - check before traveling. Tet (Lunar New Year) is magical but everything closes. Vietnam is safe but watch for pickpockets in tourist areas.
