Wi-Fi Calling (Gọi Wi-Fi / VoWiFi) lets your +84 mobile number ring and text over Wi-Fi anywhere abroad — essential for receiving Vietcombank, BIDV, Techcombank, Momo, ZaloPay, and VNeID SMS OTPs while you're outside Vietnam. Vietnam has no EU-style roaming pact — carriers charge for international roaming — so Wi-Fi Calling + a travel eSIM is the reliable playbook. What to check for Viettel, VinaPhone, and MobiFone.
