Pros
- The free 1GB requires neither a credit card nor a purchase.
- One eSIM serves 200+ countries and regions, avoiding the need to install another eSIM for each trip.
- You can retain your existing SIM for calls, SMS and two-factor authentication; check your main network's roaming settings before travelling.
- USIMS states that the eSIM itself has unlimited validity, while each data plan has its own validity period; confirm the validity displayed for the individual plan before purchasing.
Watch out for
- The free 1GB covers only the USA and Europe and has separate conditions from low-speed Free Essentials.
- The US$3 credit mentioned in the invitation message remains unconfirmed by official pages.
- Hong Kong plans may cost more per GB than some European options. One listed example was 1GB for 10 days at €20; prices and available durations may change, so check the app.
- An unlocked, eSIM-compatible phone is required.
FAQ
- What is available through the USIMS invitation link on this page?
- New users can receive 1GB of free data for the USA and Europe, as listed in USIMS's FAQ and app listing. USIMS's blog also states that invited customers receive 20% off their first purchase. The additional US$3 credit mentioned in the invitation message has not been officially confirmed and should not be treated as an available balance.
- Can Hong Kong residents use USIMS in the UK or Hong Kong?
- Yes. USIMS is available in the UK and Hong Kong app stores, and both destinations are served. Hong Kong has paid plans. The free 1GB covers the USA and Europe, but USIMS has not clarified whether the UK is included; check the destination list in the app. For other destinations, compare paid plans and the separate low-speed Free Essentials service, including its supported apps and conditions.
- Does USIMS provide a phone number?
- No. USIMS is a data eSIM and does not provide a regular phone number for voice calls or SMS. Retain your existing SIM if you need calls or text messages.
