Overview
USIMS (app: com.wonet.usims, developer Wonet) gives new users a free eSIM with 1GB of data in the USA and Europe. Official web prices (2026-09): China $10/1GB/10d, France $9/10GB/10d, USA $15/10GB/10d. Google Play lists 'Free Essentials Forever' — always-on low-speed data in 200+ countries, no expiry. Referral program: new-user credits (third-party trackers list $3; official terms say referrals earn UMoney credits and 20% off).
USIMS is an app-first travel eSIM (Android/iOS, rated 4.6 on Google Play) covering 120+ countries from the web store and 200+ in-app. The free tier is the hook: a free eSIM for new users with 1GB in the USA and Europe, plus 'Free Essentials Forever' — always-on low-speed data in 200+ countries for messaging/maps/banking, no expiry, no card needed (Google Play What's New, 2026-09).
Official web prices (2026-09-26, usims.com): USA $15/10GB/10d, France $9/10GB/10d, China $10/1GB/10d, Hong Kong listed separately. Paid plans stack with UMoney, a non-expiring loyalty credit: up to 10% back on top-ups; referrals earn 20% of the friend's spend as credit and give the friend 20% off; five buying referrals score a free up-to-10GB package.
Community single-user hands-on (2026-09, unverified): registration with a +44 UK number received the code instantly; the free-eSIM claim pops up after lingering on the app home screen or tapping 'Refer friends'; the free eSIM lands with a native French exit IP; a 'China mainland 20 days 1GB' pack listed at $4 in-app dropped to $1 after applying the $3 new-user credit (~¥7). Note the official web store shows China at $10/1GB/10d — the $4/20d app price could not be cross-verified server-side.
Device restrictions per the same hands-on: must be an international (non-China-ROM) eSIM-capable phone — Pixel 8 tested OK, one-tap install on foreign iPhones; China-market iPhones and 5ber/eSTK adapter cards are detected and blocked. Android generates a QR to scan.
