Excellent e-SIM. Easy to install in advance. It activated upon arrival. The time countdown starts from the first connection to the network in the country of arrival. So, if you arrive at 4:00 AM, your first day of use will be updated at 4:00 AM. Conveniently, the e-SIM is valid in several countries in the region.

Good SIM card. The internet was perfect in Beijing and Hong Kong. There were a few issues in Guangzhou and Chongqing.

Reviews: Vietnam 5G eSIM | TikTok & ChatGPT Available | Day Pass/Total Data Package | 24-Hour Billing | 1-30 Days | QR Code
Guest User2026-04-24
I set it up before going to SGN and when I activated it in the airport, it is good. Data is fast all throughout my stay even in Ba Den Hills. One thing I noticed is that tiktok doesnt work on my phone when using this esim. I am using Galaxy S25 Ultra so idk if it has something to do with it. If I want to use titkok, I deactivate the sim first then connect to wifi (my friend is using the same sim but turning on her hotspot) so I can load my tiktok app. Idk if it's my phone or the sim. Anyway, it doesn't really much affect my travel.

Used in Ho Chi Minh City, it worked well without any problems. There was 5G signal even in Tay Ninh province and in the mountains; the signal was strong.

I was very pleased with the eSIM. It worked immediately at Cam Ranh Airport, and the connection was good in Nha Trang (at the hotel, on the beach), and in Dalat. I didn't have much time to surf the internet, and the hotel's Wi-Fi was good, so I could have gotten a 1GB per day plan instead of 2GB. I highly recommend it. P.S. My phone didn't support eSIM. I bought an adapter on Ozon and a plan on Trip (in case anyone finds this information useful).
