You have received your Ubigi QR code by email and now need to install it on your device, follow our step by step installation guide below:
– Press and hold the QR code received by email if your device allows it or simply scan it – A pop-up will appear at the top of the screen, click on it – Tap on “continue” and “add data plan” in the following screens – Rename the new plan as Ubigi to find it more easily – Select your local carrier for FaceTime & iMessage, – You’ll be able to use your Ubigi data for iMessage, but as your Ubigi line does not have a phone number – you can share, it is not necessary to associate it to your Apple ID – Select Ubigi for Mobile Data – Do not allow Mobile Data Switching – you would risk roaming on your local carrier

Thankful for the data during our trip
Thankful for the data during our trip. It was hard to activate it once we landed at our destination but it eventually worked after a couple of hours later.

It was awesome
It was awesome, the only thing that tucked was when I purchased the 500 mb for Macao and never was able to activate. I travel a lot so either a credit or refund for 2 dollars would be appreciated.

Best mobile provider I’ve used in Japan…
Best mobile provider I’ve used in Japan so far, most of the time you have 5G, if not fast LTE. I have not run into any problems (Tokyo to Fukuoka areas, mostly cities, sometimes rural)

Data is not recognised immediately…
Data is not recognised immediately whichever country you land, takes a while to connect. Does not pick up data in some places.

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.
If you choose to add a new one, the current plan will be removed. What would you like to do?
