Help with anti-theft

I have 5 numbers in my name, the whole family uses it. I installed Avast mobile security on one phone in order to use anti theft and be able to trace. Through my personal account, I could check calls, take photos, record sound, etc. Everything worked fine. The trial period has ended. All mentioned functions are no longer available. The phone is used by his wife, who now lives separately. The program is still on her phone.
Is it possible to renew the mentioned functions again? Is it possible to pay for the service?

Note there is a specific area in the forum for Mobile Security inc anti-theft questions. Both Android and IOS. See here:
