Why direct-from-carrier matters
Airalo and Holafly are global eSIM resellers — they buy bulk capacity from Viettel and resell it to you with their own pricing layer on top. simvietnam.telebox.vn is operated by Telebox, which has a direct partnership with Viettel and Vinaphone in Vietnam. That means: (1) lower price because there's no middle layer, (2) Vinaphone option (resellers usually only carry Viettel), (3) faster customer support because issues go straight to a Vietnamese team that can call the carrier directly, (4) accurate carrier-side troubleshooting when your phone fails to connect on arrival.
