You need something that can receive a text or voice message, but only once when you set it up, or in the future should you lose a trusted device and need to recover your account.

That "something" could be a service such as this one: TextNow. Allegedly it offers a "free phone number" that could be used do to that, but it will expire if you don't use it for a while. I have not used it but it might suffice for your needs. There are probably other, similar services. (Edit: Skype might already be able to do that: Online phone number | Skype number | Skype)

Sorry, that explanation isn't helpful, either. What happened when you tried to follow deggie's directions?

Hi,

On iPhone, go to Settings > Messages > Text Message Forwarding

Uncheck your iPad.

Hold the power and home button simultaneously until it powers off.

Thank you
