Network issues, Call Issues, SMS Issues

[AllaIhn_3228934]

Please tell me how to fix it, I have a Smarty SIM card installed on my Android smartphone, all settings are installed, 4G+ internet works, but I can't call, send, receive calls and SMS. My tariff includes unlimited calls and SMS, and 100Gb. The support webchat doesn't work, I didn't find a solution in the FAQ.
