Verizon Free Trial gives you up to 30 days of Verizon service free of charge, including:
Unlimited talk and texting
Up to 100 GB of 4G/5G Premium data* on Verizon's premium network
480p streaming with 4G/5G Nationwide; 4K streaming with 5G Ultra Wideband*
You'll have domestic calling only during the trial. International services and add-on features aren't included.
Can confirm this worked with an iPhone-12 activating from a nomad esim data only plan, not sure if your phone needs an existing plan on it first. I did not need to change countries in the Apple App store, left it as Australian.
You can try the 7-day google fi trial first (works easily on android), but be sure to cancel

You must be in the US for this to work, myself and others have tried to get it to activate prior to going, it won't work and you'll get an error message saying you've already used the trial
If you don't want to see any more Freebie deals for mobile services in other countries: Click Travel Sim Card tag, then click the ellipsis (…) menu and then check both boxes that appear.
This would send shivers down the travel sim card companies if it works easily.
