Was ist der Unterschied zwischen die Telefonnummer auf Sim speichern oder auf die E-Mail Adresse?

Uh, yes, I had saved a number before and there was the e-mail address at the top, then Sim and at the bottom device.

Sorry, I don’t know what you mean. In other words, a screen photo of the device concerned and this screen would help.

Normally, you have the option to store a phone number either on the SIM card or on the device (in the contacts there).

• To store on the SIM card is outdated. There is usually only limited space and the entries have a fixed length and often contain no more than one or with luck several phone numbers to one name.

• Save on the device in its “contacts” allows you to store a complete address data set with multiple addresses, several phone numbers, other contact options (e.g. in any messengers) etc. for a person. This is the usual solution on smartphones today.

And if your local data on the phone in the “contacts” are then synchronized with an account somewhere in the cloud (i.e. on a provider’s server), then that’s another, more question.

Of course, you can do this by syncing your contact details with your online account, for example, with Google or Apple.
