JengDeal pick: JetFi Mobile code 8emhjb — a free day of eSIM data plus 30% off
Off to Japan, Korea, Taiwan or Europe next? Register in the JetFi Mobile app with your email and type invite code 8emhjb yourself as you sign up (the link won't fill it in). You get a free eSIM voucher (1GB for 24 hours in Japan, South Korea and mainland China) plus a 30%-off coupon for the whole eSIM store. Redeem by 23:59 on 31 December 2026, when the coupon also runs out, and note that Google sign-in can't take the code. The big hurdle is your phone: Hong Kong iPhone 11 to 16 models (bar the 12 mini, 13 mini and 16e), XR and XS Max have no eSIM, and JetFi's terms exclude iPhones sold in Hong Kong, Macao and mainland China, so let the app check yours first.

Eligibility & requirements
- First-time JetFi Mobile registrants only; one free eSIM per device and per account, and it can't be combined with other new-user gifts.
- Register by email in the app and enter 8emhjb at sign-up: accounts made with Google sign-in can't enter a code, and the code doesn't work on JetFi's website.
- The free eSIM gives 1GB (e.g. Japan, South Korea, mainland China/Hong Kong/Macau, the US), 500MB (e.g. Taiwan, Canada, Europe) or 300MB (e.g. the Gulf states, Mexico) for 24 hours from first data use in the destination.
- Claim and redeem by 23:59 on 31 December 2026 (JetFi names no time zone), then activate within 180 days of redeeming; the 30% coupon also expires on 31 December 2026.
- JetFi doesn't publish the coupon's minimum spend, cap or excluded plans, and can change or cancel the offer at any time; the invite page and its terms are in Chinese only.
- Data only, with no phone number. Your phone must be unlocked and eSIM-compatible; JetFi's terms exclude iPhones sold in Hong Kong, Macao or mainland China, so let the app check your phone.

Pros
- A free day of data in one of 110 countries, with no purchase needed.
- 30% off JetFi's whole eSIM store until 31 December 2026.
- One-tap eSIM install in an app that is in English, Chinese and Japanese.
- The 24 hours only start at your first data use in the destination.
Watch out for
- The free eSIM is small: 24 hours of at most 1GB.
- Apple lists iPhone XR, XS Max and iPhone 11 to 16 models bought in Hong Kong or Macao (except the 12 mini, 13 mini and 16e) as two-nano-SIM phones with no eSIM; mainland China models also differ, and JetFi's own terms exclude iPhones sold in those places. Let the app check your phone or dial *#06# for an EID before relying on it.
- Some Android phones, such as Xiaomi models, can't use one-tap activation.
- Paid plans are credit card only, and the reward isn't cash.
