Yolla Review: International Call Rates and the US$3 Invite Credit
A practical review of Yolla's internet calling, destination-based rates, US$3 invite credit, top-up rules and the limits to check before paying.
Last updated 14 October 2026
Best for
People who need to call overseas mobile or landline numbers and are willing to check the exact destination rate before topping up.
Yolla can be useful for calling overseas phone numbers over Wi-Fi or mobile data, but the real cost depends on the destination, number type and how you top up. The invite credit is call balance, not money. New users need to make a qualifying payment; Yolla's FAQ says top-ups of US$4 or more count for referrals. Check the rate for your regular numbers first and only add the balance you expect to use.

Calling family abroad on the regular? Yolla is the app for cheap international calls to mobiles and landlines. Install it through the invite link (promo code A7T8I9), make your first payment, and Yolla's official Free Credits page says each invited friend gets a US$3 gift β with the FAQ counting top-ups of US$4 or more. If the code doesn't auto-apply on the payment screen, enter A7T8I9 in the app menu's Get bonus / Bonus (promotions) section before topping up. Pro tip: don't switch between mobile data and Wi-Fi during sign-up or the invite tracking can break. It's call credit, not cash.

What Yolla does
Yolla is an internet calling app for calls to overseas mobile and landline numbers. It works over Wi-Fi or mobile data; it is not a UK or Hong Kong mobile plan and does not replace your SIM. If you use mobile data, your own carrier's data charges apply.
It is most relevant when you need to call a conventional phone number. If both people can use the same free messaging app, compare that first.
Check the rate for the number
Yolla prices calls by destination and number type. Before topping up, enter the full number in the app and check the displayed rate, any connection charge, minimum billing increment and whether the destination is supported. There is no single rate that describes every international call.
UK and Hong Kong users should also check the currency and final amount at checkout. An in-app purchase and a web top-up may be priced differently; use the amount shown immediately before payment.
The US$3 invite credit
Use the GetQuids invite link and code A7T8I9 to sign up. Yolla's official Free Credits page says a new user gets US$3 in calling credit after their first payment. Its FAQ says a top-up of US$4 or more counts for referrals. This is app balance for calls, not cash or a transferable credit.
Open the invite link on your phone, install and sign up straight away. Keep the same Wi-Fi or mobile-data connection throughout sign-up. If the code is not on the payment screen, add it under Get bonus / Bonus before topping up. Save the order confirmation.
Keeping the referral tracked
Yolla says referral tracking can fail if you do not install and register promptly from the mobile invite link or switch between Wi-Fi and mobile data during sign-up. Complete the steps on the same phone and check that the code appears before paying.
If the invite is missing, contact Yolla through its official support route with the sign-up and payment details. A missing referral is not guaranteed to be added later.
Top-ups, refunds and balance
The US$3 reward is a Yolla calling balance. It cannot be withdrawn as cash or transferred to another person. Read the in-app terms before a paid top-up so you know the current cancellation, refund and balance-expiry rules.
Do not top up more than you expect to use. If you buy through Apple or Google, their in-app purchase and refund processes may also apply.
Call quality and customer experience
Yolla is listed in the UK App Store and Google Play; a store rating describes the overall app experience, not call quality to every country or network. Try a short call to a regular destination before relying on the service for an important conversation.
Call quality depends on both your data connection and the route to the destination. If a call is poor, check the connection and try again before adding more credit.
Who should use it
Consider Yolla if you need to call overseas conventional phone numbers, have a reliable data connection and find the displayed rate reasonable. Treat the US$3 as a small trial credit; the long-term value depends on how often you call and where.
Skip it if your contacts can use a free internet messenger, you need a local SIM plan, or you do not want to prepay an app balance.
