Where Airalo is better
If you need 50 GB for 30 days, Airalo costs less on the date checked. That advantage does not extend to the smaller allowances in the table.
Airalo names T-Mobile and Verizon for the selected plans and offers 24/7 multilingual support. That combination may matter if you already know which network works where you will stay.
Where HolySim is better
The total price is lower at 5, 10 and 20 GB. Each plan lasts 30 days, so you can spread your data use across a road trip.
The compared fixed plans name AT&T and Verizon. You can also email questions in Dutch. Listing two networks does not guarantee coverage along every road-trip route.
