SIM trays are the cheapest part in your drawer and somehow still the source of daily confusion. A tray that is 0.3 mm off seats loosely, loses contact mid-call, and comes back as a "network problem" warranty ticket. Here is the reference chart shops ask us for most.

Stock the SIM tray collection in the four footprints above and you cover every model from the iPhone 7 through 13 with four SKUs — the most efficient way to kill "no SIM detected" tickets forever.
The real fault is usually not the tray
"No SIM" after a drop or liquid event is more often the reader pins on the logic board or a damaged SIM flex. Test with a known-good tray before touching the board, and check the reader with magnification for bent pins.
FAQ
Do trays come with the eject pin? Wholesale lots include pins; single units ship without.
Water-damaged trays stick — replace? Yes, corroded trays seize and bend reader pins on removal. Cheap insurance.
