iPhone X does not recognize SIM - that's the reason

If your iPhone X does not recognize the inserted SIM card, this can have several reasons. In addition to a defect in the card itself, outdated settings can also be the cause of the appearance of the error message. We explain which steps help to solve the problem.

This card is required by the iPhone X

In order to make calls, write text messages or surf the Internet on the go with your iPhone X, you need a suitable SIM card. For the iPhone X, this is currently the smallest SIM card format, the nano SIM. If you have a nano-SIM for your iPhone X, it is necessary to insert it correctly. To do this, use the tool provided to press into the hole next to the SIM card slot so that the SIM slide pops out, and then insert the card with the contacts facing down.

Possible causes when the iPhone X does not recognize the SIM

Once you have inserted the SIM card into your iPhone X, it will normally be available to you when you turn it on. If you receive the warning message that no SIM card is inserted instead, proceed as follows:

1. First, perform a restart of the iPhone X to test whether the SIM card is subsequently recognized.
2. If a restart does not help, turn off the device, remove the card and insert it again. Stellen Sie dabei sicher, dass das SIM-Fach richtig verschlossen ist.
3. Um auszuschließen, dass ein Kartendefekt die Ursache ist, setzen Sie testweise eine andere SIM-Karte ein.
4. Manchmal kann es auch helfen, die Netzbetreibereinstellungen zu aktualisieren. Gehen Sie dafür zu „Einstellungen“ > „Allgemein“ > „Info“ und klicken Sie auf „Aktualisieren“, falls ein Update verfügbar ist.
