- You can scan the QR and install the eSIM before you travel. Days start counting when you arrive in Vietnam, and you must activate it within 60 days of purchase.
- Moderate use is about 1.5 GB a day: 10 GB is enough for 5 days. If you don't want to count data, or you watch a lot of video, pick Unlimited.
- Best Vietnam runs on Vinaphone 5G and lets you check your remaining data. Wintel is 4G, with 6GB a day at full speed, then unlimited data at 5 Mbps. You can't check your remaining data on Wintel.
- Every plan allows hotspot sharing. They are data only, with no phone number for calls or SMS, and cannot be topped up. If your data runs out, buy a new plan.
