USIMS invite: free 1GB data for the USA and Europe
Heading to the USA or Europe? Download USIMS through this invite link, sign up, and grab 1GB of free data for the USA and Europe — no card, no purchase. USIMS is a single travel eSIM covering 200+ countries and regions; when the free data runs out, just buy a plan in the app. Clear-eyed notes: the free 1GB is USA and Europe only — check the separate low-speed Free Essentials tier for other destinations — and the US$3 credit mentioned in the invite message isn't confirmed on official pages, so don't count on it. Your phone must be unlocked and eSIM-compatible.
