@DaVibe I would not worry about breaking the cards. I have many times put the nano sim back into the bigger sim and had no issues.
I've actually broken these adapters (the ones made the sim card manufactuer) a bunch of times, although the nano sim card itself remains fine.
I find they are flimy and break extrremely easily, especially the part that converts nano to micro sim size due to how thin the bordering plastic is on one of the sides. It's always that one side that has always broken on me, both on sim cards from other carriers and the Public Mobile sim card that I have.
In addition, I find that the smaller sizes fall out very easily, but this depends on the method of inserting needed to put the sim card into the phone. Phone with sim card trays are usually fine, but I find that the most finicky kind of kind of sim card slots are the ones that you have to slide in (non spring loaded) because the way you have to press down to slide it in. The smaller pieces fall out all the time from what I see.
I find that the adapters also warp when removing and reattching them a few times.
Now, or course this doesn't just happen by itself but rather when you're moving your sim card among different phones on a repeated basis, espcially if changing the sizing.
I've also seen cell phone store employees break the adapters by accident.
