Ubigi review

Ubigi is the value pick for travelers who use more data than a 1 GB pack allows. Its Europe plan gives 10 GB valid for 30 days for US$15, which works out to US$1.50 per gigabyte. The eSIM is run by Transatel, part of NTT, and is reusable across 200+ destinations, so you install it once and buy new plans for later trips. A feature called Smartstart starts the plan automatically when you arrive, so validity does not tick down while you are still at home. Ubigi also works on eSIM laptops running Windows 10/11, which few travel eSIMs mention, and the one-off plan allows data sharing. You can check your balance and top up instantly in the Ubigi app. The trade-offs: the plan is data only, so calls go through apps, and the Europe page we checked offered fixed data rather than an unlimited option. Light users will pay less with Saily's US$4.99 pack.
