Good morning @VIT88.
Welcome to the EE Community 😊
When it comes to adding products to your account, every customer has an internal credit class that determines the amount they're able to add to their bill.
This is based around your initial credit check, along with how you manage your account and bills.
There's absolutely the potential for adding more than one accessory to your account, so if you get in touch with our team they'll be able to confirm what options you have available.
