How to avoid roaming charges in Vietnam
Using an eSIM is your best option to avoid roaming charges in Vietnam, but there are other things to consider:
- Get a local SIM card: If you have a SIM-only phone, using a Vietnam SIM card is a good alternative to avoid roaming charges while still getting reliable mobile data.
- Rent a pocket WiFi: Renting a pocket WiFi for Vietnam is a good option for larger groups or remote workers, but it can cost over $100 weekly on limited data plans. Consider using Holafly Plans instead, a subscription service that includes unlimited data, unlimited mobile hotspot, 5G data speeds, and coverage in over 170 destinations for $64.90 per month.
- Use free WiFi: Free WiFi is commonly available at local airports, public areas, and coffee shops; however, it’s not always safe to rely on it for extended periods. Use it to look for addresses around Ho Chi Minh or upload pictures, but avoid using it for work or accessing personal information.
- Turn roaming off: If you’re relying on international roaming services, you can go to your device settings and turn off the “Roaming” option to reduce how much it can cost you.
Vietnam roaming vs. eSIM for Vietnam
Using international roaming in Vietnam can give you access to your local allowance, but in most cases, you’ll end up paying for an expensive international plan. Even worse, you can be hit by hidden costs due to your phone consuming background data.
Other options, such as a prepaid SIM card or a pocket WiFi, are alternatives to consider, but chances are these fall short in terms of mobile data or hotspot data, especially on extended trips.
That makes an eSIM a great alternative to data roaming, as you can pay half the price of roaming passes and still get a reliable service.
The Holafly eSIM for Vietnam or Holafly Plans are your best options, with plans starting at $1.55 daily or $49.90 monthly, ensuring you get a high-quality service for your Vietnamese adventure.
