Why am i being orompted to purchase a wireless plan on an unlocked version of this phone

Bought the unlocked version of this phone and have a provider already in place. The phone was working fine but now my daughter is being prompted to purchase the wireless plan and no apps or games etc will work. Scheduled a call from Teracube for tonight, received a text to confirm the call would go ahead but sill no call received. Can someone advise how i can fix this issue or speak to someone directly. If i cant resolve this issue i will have to return the phone as its not fit for purpose.

Welcome!

Sorry for the frustration.

Have you reached out to support@teracube.com already (it sounds it)?

If so, can you PM me your contact information so I can re-ping the support team to ensure you are contacted again.
