eSIM Vietnam

Need help at 2 am in Dubai or midnight in Bangkok? HelloRoam support is available 24/7 via WhatsApp and live chat. A real person responds in under 2 minutes. WhatsApp support is lekker for South African travellers on the move. Whether it is an installation question before you board at OR Tambo or a top-up query mid-trip, live help is always one message away.

Connect to local 4G LTE and 5G networks in Vietnam the moment you land. Buy your plan, scan the QR code, and get online when you land. No roaming charges, no SIM swap, no fuss. Local network speeds mean Google Maps, WhatsApp calls, and airport navigation all work from the second you leave the arrivals hall.

Keep your Vodacom, MTN, Cell C, Rain, or Telkom Mobile number active for calls and texts. HelloRoam runs travel data on a second eSIM line on any dual SIM compatible cellphone. No need to choose between your local SA number and your overseas data. Your mobile banking OTPs and WhatsApp calls from family still come through on your home number while HelloRoam handles all your international data.

HelloRoam connects to 204+ carrier networks across 185+ countries. If a faster 4G or 5G signal is available, your phone switches automatically. Works on Samsung Galaxy S20 and newer, iPhone XS and newer. That means strong mobile coverage whether you are in central London, the backstreets of Bangkok, or a rural stretch of Mozambique.

You will not be caught short. When you reach 80% of your Vietnam eSIM data, HelloRoam sends a notification so you can top up before running out. Add data from the app without reinstalling anything. No hunting for a local SIM shop or airport kiosk, just tap to buy a top-up and carry on.

Connect to local 4G LTE and 5G networks in Vietnam. HelloRoam picks the strongest signal automatically so WhatsApp calls, Google Maps, and video calls stay fast throughout your trip. You get the same data speeds as a local prepaid SIM, not the throttled connection that comes with SA carrier roaming bundles.

Heading to the UK, Thailand, or Mauritius and then somewhere else? HelloRoam regional plans cover Europe, Asia, and 185+ destinations in one eSIM purchase. One eSIM for your whole trip. Your device switches to the local carrier network at each border automatically, so you stay connected without buying a new SIM or logging into airport Wi-Fi.

Share your Vietnam eSIM data with a laptop or tablet using your phone hotspot. No extra fees and no setup required. Works on all eSIM compatible phones. Business travellers heading to Dubai or London can run a laptop off their travel data plan the whole trip without buying a separate portable Wi-Fi device.
