What's the difference between Firsty's Belgian plans: Free, 15GB, 100GB and World?

Free earns you data by watching ads. 15GB and 100GB are fixed monthly plans for Belgium and the EU, with extra data to use abroad. World gives you unlimited data at home and in the EU, plus data in 176 countries, for one flat monthly price.

What happens when I use up my data on a Firsty Belgium plan?

You're never cut off. On 15GB, 100GB and World, you keep going at 512 Kbps once your Belgium & EU data is used, same price, no extra charges.

Can I call with my Firsty Belgium eSIM?

Calls and texts within Belgium are unlimited on every plan, and 15GB, 100GB and World include EU calling minutes too. Need more? Top up your wallet anytime.

Will I get a Belgian phone number with Firsty?

Port your existing number for free on any plan, or get a new Belgian number, free on paid plans and €1 a month on the Free plan.

What is a Firsty eSIM?

A digital SIM you install directly on your phone, no physical card needed. One eSIM works across every Firsty plan.

How do I know if my device supports eSIM?

Most phones from the last few years do. Check your device settings for "eSIM" or "Add cellular plan," or check with your manufacturer.

Can I use my SIM card and Firsty eSIM at the same time?

Yes, if your device supports dual SIM. Firsty handles your data, your regular SIM stays active for calls and texts on your usual number.
