Should you buy your Ubigi eSIM data plan before traveling, or when you arrive?
Either is possible! You can purchase your Ubigi data plan right before you leave or when you arrive at your destination, whichever is most convenient for you. Thanks to the SmartStart feature, the validity period of your data plan starts automatically upon arrival in a covered area, ensuring you do not lose any days before your travel.
Getting started with SmartStart is easy! 🚀 Upon arrival, simply switch on your Ubigi line in your mobile settings—your data plan will activate automatically, and its validity will begin.
If you have not purchased a plan before leaving, you can buy your data plan when you arrive at your destination and it will activate immediately. Good to know: Even after you have used up all your data allowance or you have no Wi-Fi, you can still recharge from the UBIGI app anywhere in the world and check data usage.
Note: We recommend installing your Ubigi eSIM on your device before you travel. Internet connectivity is required to download the eSIM profile on your device. (For Android users, you can only install new eSIM profiles while connected to Wi-Fi).

Great expereince using it in UK
Great expereince using it in UK. However during the train ride signals would drop which made the journey not super cool. Had it been great while travelling, it would have been an easy 5 star

I couldn't have made it without UBIGI in Marrakesh! While others had no signal, I was surfing the web, using my apps, and getting business and fun done!

Easy setup and reliable service in Japan
I used Ubigi eSIM during my trip to Japan and had a great experience. Setup was quick and straightforward, and the service worked as soon as I arrived. I had reliable data throughout my trip and didn’t run into any connection issues. It was really convenient not having to buy a physical SIM or worry about roaming charges. I would definitely use Ubigi again for international travel.

Good Cellular Data Experience While In Japan
I used Ubigi for cellular data while in Japan, it was the cheapest for the month I was in Japan while also covering South Korea which I had a brief stopover in. I had no issues activating it once I was in Japan (I am tech savvy though and used to managing esims). You can check how much more data you have in the app. I didn't get nagged or anything while I had the service; the only thing was a reminder when the expiry was getting close.
