How can I find the ICCID (serial number) of my Ubigi eSIM?
The ICCID is the reference used to identity your eSIM. It consists in 19 digits, starting with “8988247…” .
It can be found in the original email we sent you with the Ubigi eSIM QR code.
It can also be found in the emails we sent you when you purchased a data plan.
But if needed, you can always retrieve it in your device’s settings:
On iOS Go to Settings > General > Information, and scroll all the way down to the “ICCID” field. (Only ICCID for active eSIMs are displayed).
On Android Go to Settings, then “About phone”, and tap “SIM Status”. The ICCID will then be displayed.
On Windows 10 (NB: instructions for Windows 11 at the bottom of the page) To find your eSIM’s ICCID: – Go to “Settings”, then “Networks & Internet”: – Select “Cellular” in the left menu – Click on “advanced options”: The ICCID will appear at the bottom (SIM ICCID):
On Windows 11: – Go to Settings > Network and Internet > Cellular then select “eSIM Profiles”:
– Click on the profile to display the ICCID:

Reliable
My husband and I recently visited Curaçao, a small Caribbean island I had never even heard of before planning our trip. I was pleasantly surprised by how well the eSIM worked throughout our stay! I experienced virtually no buffering, websites and apps loaded quickly, and our navigation never once cut out.
This was actually my third international experience with Ubigi, having previously used their eSIMs in Japan and South Korea. Both trips were incredibly smooth, so I was excited to discover they also offered coverage in Curaçao. I’m happy to say the experience was just as reliable! It’s reassuring to know I can count on the same quality of service, even when traveling somewhere a little less familiar.

Superb for off road motorcycle Morocco
I was off on an off road motorcycle tour to the High Atlas in Morocco and needed good coverage and unlimited data - just in case.
The eSim download, sim switch and usage was faultless and superb coverage 5* in most areas. Actually better than my Virgin sim in Cheshire.
For the money is was complete peace of mind and a vital comms link.

Flawless
Flawless. Set it up before I arrived in Ireland. Switched over to the esim when I landed and it worked straight away.
I didn't realize it can't be used for local calls but that's not an issue for me as I just use an app instead.

Connection was pretty much spotless
Connection was pretty much spotless except for the first time I activated in JFK. I had to go connect to the airport wifi to reach my airport pickup but the rest of the way was perfect. Good value compared to other providers too.
