Mandatory registration for local SIM cards
Under Decree 49/2017/ND-CP, local physical SIM cards sold in Vietnam require strict identity verification with a passport and in-person portrait photo. Overseas travel eSIMs roam on Vietnamese partner networks and activate without in-country paperwork.

Mountain and island coverage
Coverage is strong across major cities and the Mekong Delta, but signal can vary in remote northern regions like Ha Giang and mountainous national parks. Viettel typically maintains the widest coverage in remote areas.
