Mobile, Broadband & Travel eSIM Referral Offers

Provider

Saily

HK$39–HK$78 off

Saily has no HKD account, so you pay in a foreign currency such as US dollars: JIMMYU6940 takes US$5 off a standard plan or US$10 off Ultra on your first order (€4/€8 in euros, £4/£8 in pounds). The plan must cost at least US$5.60, so 1GB plans don't count; no stacking with other codes, and top-ups are full price after that. Hong Kong-bought iPhone 11 to 16 (except the 12 mini, 13 mini and 16e), XR and XS Max have no eSIM: dial *#06# for an EID before you buy.

Requirement: First purchase; USD minimum US$5.60, EUR €5, GBP £4.50; no combination with other promotions

Provider

Airalo

HK$23 off

Pick the data pack for your trip, then use JIMMY2336 for US$3 off your first Airalo order. One discount per order, so it's the code or Airmoney, not both, and there's no HKD, so you pay in US dollars or another listed currency. Hong Kong-bought iPhone 11 to 16 (except the 12 mini, 13 mini and 16e), XR and XS Max have no eSIM: dial *#06# for an EID before you buy.

Requirement: First purchase only; Airalo's Refer and earn page lists no minimum spend

Provider

HKBN

Up to HK$400 off

Thinking of moving to HKBN? Open this page’s link and pop KWOKCWJ03554 into the promo code box. Once the service is live and you’ve paid the first bill, HKBN takes the credit off your bills within 8 weeks: HK$400 for 24-month broadband, HK$150 for 24-month mobile, or HK$100 or HK$50 for 24- or 12-month streaming. It’s bill credit, not cash in your bank, so only sign a plan you actually want.

Requirement: A designated 24-month broadband or mobile plan, or a 12/24-month streaming plan, with the first bill paid

Provider

Google Fi

HK$468 credit

Google Fi is Google's US mobile service, so people living in Hong Kong generally can't sign up. You'll need to be a US resident aged 18+, have a physical US primary home address, activate in the US and use Fi mainly there. If you qualify, use this page's referral link and code M0APFR to get US$60 towards your Fi bills. Google's official Referrals page says the credit comes after you pay your first month's bill. You'll also need to activate a new full-service plan within 30 days of checkout, keep it active for 30 consecutive days and pay your first bill in full. Data-only SIMs and joining an existing group plan don't count. The US$60 goes towards Fi service charges; it isn't cash and won't pay for a phone.

Requirement: Start an eligible new full-service Fi plan, keep it active for 30 consecutive days and pay your first bill in full

Provider

JetFi Mobile

Free eSIM, 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.

Requirement: No purchase needed for the free eSIM; JetFi doesn't publish the 30% coupon's minimum spend, cap or excluded plans

Provider

GigSky

25% off first plan

Want data the moment you land? GigSky covers country, regional and global plans, plus cruise data on supported ships and inflight data. Sign up through the referral link or type JIMB150 in the referral code field when you create your account, verify your email, and your first data plan is 25% off. Heads-up: the code can't be added after sign-up, only one discount applies per purchase (a bigger one, like an eligible Visa card's 30%, replaces it), and GigSky One subscriptions are excluded. Check the order summary shows 25% off before paying, and make sure your phone is eSIM-compatible.

Requirement: First GigSky data plan; enter JIMB150 at sign-up and verify your email for 25% off

Provider

Global YO

HK$78 credit

Download Global YO through our link, open a new account and buy your first data plan, and the in-app invite screen says you get 1,000 YOYO$ (shown as $10) for later data deals and discounts. Signing up alone earns nothing; YOYO$ are app points, not cash, and each plan screen caps how much they cover. Plenty of Hong Kong iPhones have no eSIM, so check yours first. The live app terms decide.

Requirement: Buy your first data plan after joining through our link; signing up alone earns nothing

Provider

Rebtel

HK$78 credit

Calling family in the UK or Canada, or topping up a phone abroad? Sign up through our invite link on the web page it opens, buy at least US$5 of pay-as-you-go credit there (not through the App Store), and Rebtel adds US$10 of credit. Brand-new customers only, and free trials or deals don't count. It's not cash: check its expiry under Expiring Free Credits in the app.

Requirement: Buy at least US$5 of pay-as-you-go credit (Rebtel's invite terms; its help centre says US$1); free credits, deals and trials don't count

Provider

Roamless

HK$39 credit

Roamless is one global eSIM you install once and use in 200+ destinations, paying as you go. Enter referral code JIMMYQZD in the app within 30 days of opening your account (before you pay), then buy at least US$5 of credit or a data plan within 30 days of sign-up, and US$5 of credit lands in your pay-as-you-go balance. Heads-up: it can't share a purchase with a promo code; the credit can't buy data plans or Unlimited plans and isn't cash; data plans run 30 days from first use, and the terms let Roamless cancel credit after 12 months of inactivity. Many Hong Kong-bought iPhones are dual nano-SIM with no eSIM, so check yours first.

Requirement: Enter code JIMMYQZD in the app before you buy, within 30 days of creating your account, then buy at least US$5 of credit or a data plan within 30 days of sign-up. Referral and promo codes can't be combined on one purchase

Provider

Kolet

HK$23 off

Buying a Kolet eSIM? Order in the Kolet app — codes don't work on the website — then tap '+ Add a promo code' at checkout and enter GETQUIDS for US$3 off your first plan. Things to know: new customers only (not if you've bought before or claimed the free 1GB gift), it's for a plan for a trip abroad, not your home market, and it's one promo code per order, though Koins can go on top. Confirm the US$3 discount shows before paying, and make sure your phone is eSIM-compatible.

Requirement: First Kolet eSIM plan purchase; US$3 off with GETQUIDS at checkout in the app

Provider

Yolla

HK$23 credit

Get started with Yolla through the invite link on this page and code A7T8I9. The app lets you make low-cost calls to mobiles and landlines worldwide using Wi-Fi or mobile data. You'll need to make a paid top-up first: Yolla's official Free Credits page says invited new users get US$3 added to their balance after their first payment, and its FAQ says only top-ups of US$4 or more count for referrals. If A7T8I9 doesn't appear on the payment screen, enter it in the menu's Get bonus / Bonus (promotions) section before topping up. Check the call rate, payment currency and total in the app so you know what you'll pay.

Requirement: Your first paid Yolla top-up; its FAQ says only top-ups of US$4 or more count for referrals

Provider

Anytime Mailbox

$10 gift card

Sign up for an Anytime Mailbox virtual mailbox through this referral link and, under the "Give $10, Get $10" programme, you receive a $10 USD Amazon gift card once you complete sign-up and pay at checkout. Anytime Mailbox gives you a real street address at 2,000+ locations (1,937 in the US) where mail is received, scanned and managed online. The reward is an Amazon gift card, not account credit or cash, and the referral has to stay a paying customer for at least three months.

Requirement: No reward unless you complete sign-up and pay at checkout for a plan; the account must remain a paying customer for at least three months

Provider

CHARGESPOT

Charging coupon

Phone running low in Hong Kong? Use this page’s button to get the CHARGESPOT app, sign up as a new user and enter FRD9167B3F3 under My Account → Coupons → Enter Code to Redeem. Check the coupon: its value and expiry are not publicly listed. Standard rentals cost HK$8 an hour, up to HK$30 a day; some stations differ. Paying without a credit card generally means a HK$198 deposit, refunded only after you request it in the app, with up to 14 days to wait. There are 6,000+ Hong Kong stations, but check for a free return slot and confirm billing has stopped.

Requirement: No spend to register; rentals need a credit card or a refundable HK$198 deposit

Provider

Eskimo

Free 500MB

Free data with no card needed: that's what we call generous. Download Eskimo through the link and sign up with referral code CWJK257 (forgot it? You can add it within 24 hours of signing up) to get 500MB of Global data, usable in 111+ countries according to Eskimo, with no purchase. The data has no expiry date, so leftovers wait for your next trip, but an account with no activity at all for more than two years gets cancelled. It stops at zero with no auto-charge, and the in-app scratch cards can add more data (Eskimo doesn't publish how much each one pays). You can claim it on any phone, but you need an unlocked eSIM phone to install and use it; Hong Kong iPhone 11 to 16 models (bar the 12 mini, 13 mini and 16e), XR and XS Max have no eSIM.

Requirement: No purchase required; sign up with code CWJK257 for the free 500MB

Provider

Firsty

€3 off first plan

Nothing ruins a trip like landing with no data. Download Firsty with referral code 69SR-OUUA and get €3 off your first paid plan of at least €4, so a 1 GB Classic bundle drops from €4.50 to €1.50. The catch: it can't be combined with other offers, the €2.50 500 MB bundle and a €3.50 single Unlimited day are under €4, and Firsty Free doesn't count. Free also isn't available on Hong Kong +852 numbers, but the paid-plan discount still works. Many Hong Kong-bought iPhones have no eSIM, so check yours first.

Requirement: New Firsty users: €3 off the first paid plan (minimum purchase €4); can't be combined with other offers

Provider

Red Bull MOBILE Data

Free 100MB

Want to try a travel eSIM? Use this page’s link to install Red Bull MOBILE Data, then enter RCALF78de4WRFZvy in the app. The first 100MB is advertised as free in the official app listings. Any extra referral reward is unconfirmed, so do not budget for it. A1 Telekom Austria runs the service across 100+ countries. Check your destination and plan expiry before you set off.

Requirement: No purchase for the first 100MB; enter RCALF78de4WRFZvy in the app

Provider

USIMS

Free 1GB US/Europe

Heading to the USA or Europe? New users can download USIMS through this page's invite link and sign up for 1GB of free data without buying a plan. One travel eSIM works across 200+ countries and regions, and you can buy more data in the app when you need it. There's also a separate Free Essentials tier offering low-speed data for selected apps in 200+ destinations; check its rules separately from the 1GB trial.

Requirement: Nothing to buy for the free 1GB in the USA and Europe

Provider

Wispr Flow

1 month Pro free

Tired of typing? Wispr Flow turns your voice into text, and signing up with referral code JIMMY146 doubles the trial: 30 days of Pro instead of the standard 14. The trial lands at sign-up, with no word count to hit first. If you talk faster than you type, 30 days of free Pro is well worth a spin.

Requirement: The 30-day Pro trial is applied at sign-up.
