Not perhaps the cheapest but incredibly easy to use and reliable. Land at the destination, turn it on and it works, no messing about. Won't use anyone else

My travel to Vietnam
The sign up was easy and the activation was quick. The data coverage was good, however, I look forward to be able to use the 5G service instead of LTE.

Your service was easy and straightforward to use! The service worked the instant we landed in Europe, and provided reliable and fast service throughout our trip, helping us to navigate several European cities we had never been to before. On my next trip... Ubigi will be part of my pre-trip planning and preparation!

I had trouble downloading the esim to my phone before landing in the designated country. My husband didn't have a problem, but for some unknown reason I had to try several times. I was not happy.

How to check if a device is ready for eSIM?
Check eSIM compatibility
Smartphones & Cellular Tablets:
Dial (*#06#). If an EID number shows, your device supports eSIM!
Laptops (Windows 10/11):
Open your flyout (bottom-right corner). If Cellular settings are visible, your laptop supports eSIM!
Check Carrier Unlock
On iOS:
Go to Settings > General > About, scroll to Carrier Lock. If it says "No SIM restrictions", your device is unlocked!
On Android:
Go to Settings > Network & Internet > Mobile Network, turn off Auto network selection. If you see multiple available networks, your device is unlocked! If only one appears, or you get an error, it may be locked.
You already have an eSIM in your cart.
Each order can only include one eSIM data plan.
Current plan: •
If you choose to add a new one, the current plan will be removed. What would you like to do?
