Question 1

What Saily referral code should I use?

Accepted Answer

Use referral code JIMMYU6940 during Saily checkout, or start from the referral link on this page.

Question 2

How much does the Saily code save?

Accepted Answer

Saily's referral terms: US$5 off a standard plan or US$10 off an Ultra plan on a USD account (€4/€8 EUR, £4/£8 GBP), first purchase only, on plans of at least US$5.60, €5 or £4.50.

Question 3

Is the Saily offer cash?

Accepted Answer

No. It is a checkout discount on a Saily eSIM data plan, not cash or cashback.

Question 4

Should I buy Saily just for the discount?

Accepted Answer

Only if the destination, data allowance, expiry and eSIM compatibility fit your actual travel needs.

Question 5

What Airalo referral code should I use?

Accepted Answer

Use referral code JIMMY2336, or start from the referral link on this page: it opens Airalo's sign-up page with the code attached.

Question 6

How much is the Airalo referral discount?

Accepted Answer

Airalo's Refer and earn page says US$3 off your first purchase, shown as £2.50 when you pay in pounds. Only one discount method works per order, so it can't be combined with Airmoney or another code.

Question 7

Is the Airalo reward cash?

Accepted Answer

No. It is a discount on your first Airalo eSIM purchase, not withdrawable cash.

Question 8

Does Airalo work on my phone?

Accepted Answer

You need an unlocked phone that supports eSIM. Many iPhones bought in Hong Kong, Macao and mainland China have none, so check Airalo's device list, or dial *#06# for an EID, before buying a data pack.

Question 9

What is the Google Fi referral code?

Accepted Answer

M0APFR. The referral link on this page applies it automatically at checkout; otherwise enter it in the promo code box on the Google Fi checkout page.

Question 10

How much do I get with a Google Fi referral?

Accepted Answer

A US$60 bill credit, per Google Fi's official Referrals page. It arrives after 30 consecutive days of active service once your first bill is paid in full, and it is applied to later Fi bills.

Question 11

Can I use Google Fi in the UK or Hong Kong?

Accepted Answer

Not as a resident there. Google Fi is only available in the United States: you need a US home address, must activate in the US and use the service mainly in the US. International roaming on a US Fi plan is for trips abroad, not for living outside the US.

Question 12

Is the US$60 paid in cash?

Accepted Answer

No. It is a service credit on your Google Fi bill. It covers data, calls, texts and device protection charges, not phone purchases or financing, and it can't be transferred or redeemed for cash.

Question 13

What JetFi Mobile invite code should I use?

Accepted Answer

Type invite code 8emhjb when you register by email in the JetFi Mobile app. Our link opens a general download page and doesn't fill in the code for you.

Question 14

What do I get with the JetFi invite code?

Accepted Answer

A voucher for one free eSIM (1GB, 500MB or 300MB for 24 hours, depending on the destination) and a 30%-off coupon for JetFi's eSIM store. Redeem the eSIM by 23:59 on 31 December 2026; the coupon expires the same day.

Question 15

Is JetFi Mobile available in English?

Accepted Answer

Yes. JetFi says the app is in English, Traditional Chinese and Japanese. Only the invite page and the free eSIM terms are in Chinese.

Question 16

What GigSky code should I use?

Accepted Answer

Enter code JIMB150 in the referral code field when you create your account, or sign up from the referral link on this page. It can't be added after sign-up.

Question 17

How much does the GigSky code save?

Accepted Answer

25% off your first data plan purchase, applied once your email is verified. Only one discount applies per purchase, so a bigger discount you qualify for replaces it.

Question 18

Is the GigSky discount cash?

Accepted Answer

No. It is a percentage discount on your first eSIM plan purchase, not cash or cashback.

Question 19

What do I get through the Global YO link?

Accepted Answer

Global YO's in-app invite screen says that when you join through our link and buy your first data plan, you get 1,000 YOYO$, shown as $10. You spend them on later data plans and discounts, up to the cap on each plan screen; the live app terms decide the final amount.

Question 20

What are YOYO$ worth?

Accepted Answer

Google Play puts 100 YOYO$ at US$1, though Global YO's terms call any value shown an estimate. They mainly discount data plans, up to the cap on each plan screen.

Question 21

Can I cash out YOYO$?

Accepted Answer

Not as a rule. Eligible users in places Global YO and Bancus have approved can move them to a Bancus Visa card (minimum 1,000 YOYO$, 4% fee). Whether the UK or Hong Kong qualifies isn't confirmed, so treat YOYO$ as a discount on your next plan.

Question 22

How do I get the Rebtel US$10 invite credit?

Accepted Answer

Sign up through our invite link on the web page it opens, then buy at least US$5 of pay-as-you-go credit. Rebtel's help centre says the US$10 is added once your first payment goes through. You must be new to Rebtel, and free trials don't count.

Question 23

Can I withdraw the Rebtel credit as cash?

Accepted Answer

No. It's Rebtel Credits for international calls and mobile top-ups, and it can't be cashed out, refunded or transferred.

Question 24

What can I use the Rebtel credit for?

Accepted Answer

Calls to mobiles and landlines abroad, or mobile top-ups to more than 150 countries. It doesn't cover emergency calls, and top-ups can't go to UK or Hong Kong numbers.

Question 25

When does the Rebtel credit expire?

Accepted Answer

Rebtel's help centre says credit lasts until 12 months of account inactivity, but its terms give referral credit its own expiry, and another help article says gift minutes normally last 30 days. Check the date under Services > Expiring Free Credits in the app and use it soon.

Question 26

What Roamless referral code should I use?

Accepted Answer

Use referral code JIMMYQZD in the app within 30 days of creating your account, or start from the referral link on this page.

Question 27

How do I get the Roamless US$5 credit?

Accepted Answer

Enter JIMMYQZD in the app within 30 days of creating your account, then buy at least US$5 of credit or a data plan within 30 days of signing up. Roamless's help centre says you then get US$5 of credit.

Question 28

Does Roamless data expire?

Accepted Answer

Data plans last 30 days from first use, and Unlimited plans end after the days you bought. Roamless says credit, including referral credit, has no expiry date, but its terms let it cancel credit after 12 months of inactivity, and deleting your account deletes it.

Question 29

What Kolet promo code should I use?

Accepted Answer

Enter referral code GETQUIDS in the “+ Add a promo code” field at checkout in the Kolet app.

Question 30

How much does the Kolet code save?

Accepted Answer

Kolet's refer-a-friend page says new customers get US$3 off their first plan. Kolet states it in US dollars, so check the order summary if you pay in pounds or euros.

Question 31

Why is my Kolet referral code not working?

Accepted Answer

The usual reasons: you have bought from Kolet or claimed its free 1GB gift before, you are ordering on the website instead of in the app, the plan is for your home country, or another promo code is already on the order. Only one promo code works per order.

Question 32

What is the Yolla promo code?

Accepted Answer

A7T8I9. The invite link applies it; if not, enter it in the app menu's Get bonus / Bonus section before topping up.

Question 33

How much free credit do I get?

Accepted Answer

US$3, added to your balance after your first Yolla payment, per Yolla's official Free Credits page. Yolla's FAQ counts top-ups of US$4 or more.

Question 34

Can I use Yolla in the UK and Hong Kong?

Accepted Answer

Yes. The Yolla app is on the UK and Hong Kong App Stores and Google Play, and it calls numbers worldwide.

Question 35

What do I get for signing up?

Accepted Answer

A $10 USD Amazon gift card under the "Give $10, Get $10" programme, once you sign up through the referral link and pay at checkout. It is an Amazon gift card, not cash or account credit.

Question 36

When does the gift card arrive?

Accepted Answer

Rewards usually post to your account about 24 hours after a qualifying sign-up, but Anytime Mailbox says it can take up to two weeks.

Question 37

Is there a catch to keep the reward?

Accepted Answer

The qualifying sign-up has to include payment at checkout, and the account must stay a paying Anytime Mailbox customer for at least three months. Cancelled, refunded or reversed transactions do not count.

Question 38

What is Anytime Mailbox?

Accepted Answer

A virtual mailbox service that gives you a real street address at 2,000+ locations (1,937 in the US). Your mail is received, photographed and uploaded, and you can open and scan, forward or shred it from the app or web portal.

Question 39

Do I have to sign up through the referral link?

Accepted Answer

Yes, for the reward to be attributed. The link opens the Anytime Mailbox referral programme sign-up so the "Give $10, Get $10" reward can be credited.

Question 40

What Eskimo referral code should I use?

Accepted Answer

Sign up with referral code CWJK257, or use the referral link on this page. If it didn't go in, Eskimo's referral page says you can add it within 24 hours of signing up.

Question 41

Is the Eskimo 500MB really free?

Accepted Answer

Yes. Eskimo's referral page says the 500MB is credited when you sign up, with no purchase or card details. When it runs out the connection stops; you aren't charged automatically.

Question 42

How long is the free Eskimo data valid?

Accepted Answer

Eskimo's terms give data plans no expiry date. But if your account holds data and has no connection, data use, purchase or transfer for more than two years, Eskimo cancels it and the data is forfeited, after trying to warn you at least 30 days ahead.

Question 43

What Firsty referral code should I use?

Accepted Answer

Use referral code 69SR-OUUA, or start from the referral link on this page; if it isn't applied at checkout, enter it yourself.

Question 44

What does the Firsty referral give me?

Accepted Answer

€3 off your first paid plan of at least €4, per Firsty's terms, so a 1 GB Classic bundle costs €1.50. It can't be combined with other offers.

Question 45

Is the Firsty offer a cash reward?

No. It's a discount at checkout on a paid plan, not cash, and it doesn't apply to Firsty Free.

What is the Red Bull MOBILE Data referral code?

Accepted Answer

Use RCALF78de4WRFZvy in the app's referral code field.

What do I get with the USIMS invite link?

Accepted Answer

New users get 1GB of free data for the USA and Europe, confirmed on USIMS's FAQ and app listing. USIMS's blog says invited friends also get 20% off their first purchase; the US$3 credit in the invite message isn't confirmed officially.

Question 50

Can I use USIMS in the UK or Hong Kong?

Accepted Answer

Yes. The app is on the UK and Hong Kong app stores, and both are USIMS destinations. The free 1GB only covers the USA and Europe; USIMS doesn't say whether the UK counts, so check the app. For other destinations, compare paid plans and the separate low-speed Free Essentials tier in the app.

Question 51

Does USIMS give me a phone number?

Accepted Answer

No. It is a data eSIM; keep your main SIM for calls and SMS.
