SIM card not showing in account

[Trex1]

Hi. 
I’ve just received my SIM card. When I go into my O2 account to activate it, the account says I don’t have any products associated with the account. 
I’ve put the sim into the phone but though it shows 4G, it won’t give me an option to connect to my home’s WiFi. 
What can I do to rectify it please?

We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. If you message O2 using the links below, they should be able to help you with this
or give them a call on 202  or 0344 809 0202

Connecting to your home WiFi doesn't sound like a SIM problem to me. 

What make and model of 'phone are you using ? We can then try to give you some guidance to follow.
