If a sim has been terminated, you would think their system will not allow credit to be added to it. It was probably terminated either because there was no credit on it at all, or because it was not used in the minimum required activity period. Which I think is 12 monhs.

Good thing you were able to finally get your credit transfered to another sim

PS. When I check the credit on my +44 sim it also says "no expiry". I do not believe that any bit!
