Update: February 5th, 2019. Google Fi seems to have outages, or very poor support for data service around Hanoi. We haven’t been able to get reliable data with Google Fi for the past few days. The phone connects to a network, but doesn’t get any data from it. We’ve only texted this in the north of Vietnam.

Update: I had success by changing my “Preferred network type” to 3G and manually selecting a network. If the network wasn’t able to connect, toggling back the automatic network selection works. I reached out to Fi to see if there’s a more stable solution.


We landed in Vietnam on January 25, 2019, and realized that Google Fi seemed to be working on our phones as soon as 30-40 minutes after arriving. This was confusing because typically, Google Fi sends you a notification when you land in a new country. The notification this time said something along the lines of, “You’re not covered in Vietnam.” Nevertheless, we tried to use Google Fi, but SMS messages took about a day or two to start fully working for us.

Yes. Google Fi works in Vietnam. This seems to be a very recent development. When we booked our trip to Vietnam in late 2018, we researched if Google Fi had coverage in Vietnam, and the answer seemed to be ‘no.’

The best service we get is “H+,” but it certainly does the trick. So far, we have not experienced any issues with Google Fi in Vietnam except for small lapses of coverage here and there. It’s important to note that we’ve only tested this coverage in Hanoi (Vietnam’s capital city) and we have heard from other travelers that coverage works in Ho Chi Minh City.

How well does Google Fi work while traveling?

Google Fi has been a critical part of our travel strategy because we don’t have to worry about getting any local SIM cards when we land in a new city. This helps us immediately get the current conversion rate for currency by using apps and book a taxi from the airport.

Data can often be cheaper if you use a local SIM card. If you’re using a lot of data on a daily basis, or want to tether your phone to get WiFi in locations that don’t offer it, the data rates can start to add up with Fi. You’ll never pay more than a certain amount (because the data eventually gets capped), so it’s for sure worth checking out.

Which phones work with Google Fi?

Google Fi recently announced their beta support for phones other than Google phones. We use theGoogle Pixel 2 and have had no major issues with the service. I’ve heard from other friends and travelers that iPhones work okay, too! Data tethering starts to fall apart with iPhones, but we expect that to be supported more and more as time goes on.
