What is the Ubigi travel eSIM?
Ubigi is the travel eSIM most likely to follow you into the sky — it's the data partner for several major airlines' in-flight Wi-Fi alongside its 200+ country roaming plans. A free 1-day trial in 100+ countries makes it easy to test.
On the ground, Ubigi offers competitive per-GB pricing and 5G roaming where supported. In the air, on partner airlines (including Lufthansa group), Ubigi sessions can be cheaper than buying Wi-Fi at the seat. Monthly subscription plans are a neat option if you travel constantly.

Ubigi eSIM — FAQs
Is the Ubigi eSIM compatible with my phone?
Ubigi works on any eSIM-capable handset, including iPhone XS and newer, Google Pixel 3 and newer, and Samsung Galaxy S20 and newer. If your phone supports dual SIM with one physical and one eSIM, you can keep your UK number active alongside it.
How much data do I really need on a Ubigi plan?
For typical holiday use — maps, messaging, social, the odd video — 1GB lasts most people 3–4 days. Heavy streaming or hotspotting your laptop can burn through that in an evening, so size up if you plan to work or stream on the go.
Can I keep WhatsApp on my UK number while using Ubigi?
Yes. WhatsApp, iMessage and calls stay tied to your UK SIM. Only mobile data is routed through the Ubigi eSIM, so friends and family reach you the same way as at home.
The verdict
Ubigi is a quiet overachiever. The 200-country footprint, 5G support and in-flight compatibility make it the most versatile pick on this list — especially if you take a free day's data for a spin first.
