★★★★★

"Finally a SIM that just works everywhere. I've been to 12 countries this year and haven't had a single issue. The $29.99 plan is an absolute steal."

— Sarah M., Digital Nomad
★★★★★

"I used to spend a fortune on roaming or scrambling to buy local SIMs at airports. Fonus sorted all that. Set up in minutes, works instantly when you land."

— James T., Frequent Business Traveller
★★★★★

"I'm based in the UK and travel 8 months a year. The UK local number feature alone is worth it — clients always reach me on the same number. Brilliant product."

— Rachel K., Travel Blogger

Common Questions

Everything you need to know.

Does it really work in 100+ countries with no extra charges? ▾
Yes. All Fonus plans include unlimited data, calls and texts in 100+ countries with absolutely no roaming surcharges. Your monthly price is your total cost — nothing extra when you land abroad.
Can I keep my existing UK/US phone number? ▾
You can port your existing number to Fonus. You can also hold multiple local numbers from 15 different countries simultaneously on a single Fonus account — great for business or expat life.
Do I need to unlock my phone? ▾
You'll need an unlocked phone to use the physical SIM. Alternatively, eSIM activation works on most modern iPhones and Android devices regardless of carrier lock status — check with your device manufacturer.
Is there a contract or minimum term? ▾
No contracts, no minimum term. Fonus is month-to-month. Cancel whenever you want, no fees, no fuss.
What's the difference between Plus and Max? ▾
Both are unlimited — the difference is speed after heavy usage. Plus stays at full 5G/4G LTE speed for your first 20GB, then reduces. Max maintains full speeds throughout with no hard data cap, subject to network fair use.
How does the Fonus app work? ▾
The Fonus app uses VoIP technology for calls and texts, meaning it works over both mobile data and Wi-Fi. You can set it as your default dialler on iOS and Android so all calls automatically route through Fonus.
