Your balance will be displayed on the screen. It will also be shown every time you make a call. You can check your balance in the CitySIM menu on your handset as well.

Q: How do rates work?
A: The calling rates depend only on the country of your stay. E.g. if you stay in China, you pay nothing for incoming calls and flat per minute rate for all outgoing calls. It does not matter where you call: to China, or your home country, or anywhere else in the world. However, there are a few destinations with additional rates. If you call from anywhere to one of these places, there is an extra rate addition to an outbound call price. There’s special rate of €0.19 for outgoing calls to CitySIM numbers and to voicemail in the countries with free incoming calls. E.g. if you stay in Norway (where incoming calls are free), you call a friend’s CitySIM or your voicemail for just €0.19. Even if your friend is in a country with charged incoming calls. A text message costs €0.06 within the EU  and every message from CitySIM menu (CitySMS), otherwise mostly €0.35. Incoming text messages in all countries are free of charge. You can download all rates in "Rates" section. The prices are continuously falling, which means that you will be able to talk longer in the future for the same money. 

Q: Why is CitySIM so cheap?
