Does your SMARTY SIM card work in another handset, @Malgorz_2638094? 

Perhaps your SMARTY plan is paused, or has expired. 

Because forum members can't look at your SMARTY account, it might be better chatting to the online SMARTY support team - https://smarty.co.uk/contact, who're available 8am - 8pm everyday.

Hi @Malgorz_2638094 👋
When you say your phone isn't working..... can make/receive calls and are you able to text and use data? Are you in the Midlands? Is the make/model of your phone supported by SMARTY? 
I ask this as SMARTY recently turned off their 3G network.
Unless your phone has the capability/ability for WiFi calling /VoLTE and it is enabled then you will not be able to make/receive calls (but you can still text and use data). 
If this is the case then it may be down to the reason I have outlined in a post I made with regards to this problem......
