Vietnam has solid 4G LTE and 5G coverage in major cities like Ho Chi Minh City, Hanoi, Da Nang, Hoi An, and Phu Quoc. Top carriers are Viettel Mobile, Mobifone, and Vinaphone. Rural areas can be spotty, so check coverage maps on nPerf if you plan to travel outside the cities.

Local SIM cards require passport verification, so global eSIMs are often more convenient.

Cities and tourist areas usually have strong 5G. Remote regions may drop to 4G or 3G, so multi-network eSIMs like Ohayu can help maintain a stable connection. Install your eSIM before your trip so it&rsquo;s ready on arrival, and combine with hotel Wi-Fi if you want to save data.
