Any hints to get sim in a iPhone 7?

Too thick or too wide?

It is hard to see how to punch out the nano size. It only fits in one way.

It should be nano SIM size.  Make sure the gold side is facing up.

@Rilea...once you've selected the correct sim size...it should just nest neatly in the tray. The corner of the sim is clipped so will only fit one way.

I have made it the smallest, but it is too thick to go on tray. Do I trim to size of hole?

Use a straightened out paper clip or a SIM card tray pin ejector. Find the Sim tray usually in right side (if facing) phone. Then  push pin into hole..press fairly hard. It should come out. If phone is in a case....remove the case.

@Rilea...what exactly, is your question ?

To get the sim in your i7, you pop open the sim tray and install sim.
