Reuse T-Mobile cut-to-use-for iPhone SIM card back to regular T-Mobile phone?

Is that possible? My SIM card has been cut to fit on iPhone but I'm going to sell it next month to go back to regular T-Mobile phone.

I still have the cutout piece from original T-Mobile SIM Card. Can I re-attach micro SIM to original T-Mobile card and use it on new T-Mobile phone, or would I have to buy the new SIM card and activate it again on pay-as-go-plan?

Sim cards are free from t-mobile. You can try to use it but I doubt it will work.
