Iphonessa ja Ipadissa eri e-mailit. Voiko vaihtaa esim. Ipadissa ja miten?

An AppleID account is intended to be used for life. If you need to change the primary email address that identifies your account, or your secondary (recovery) email addresses or trusted telephone numbers, you simply need to update your AppleID account as necessary.

Few of us will have the luxury of forever keeping the same email addresses or telephone numbers - sometimes these needing to be changed for a variety of reasons. However, updating our AppleID account, maintaining access to our data and purchases, is easy and relatively straightforward - accommodating life’s many changes as they occur.

Using a completely different AppleID account can introduce many complications and issues, not limited to losing access to paid Apps, subscriptions and services - these being forever tied to the AppleID account from which they were purchased.

Different emails on iPhone and iPad. Can I change it on iPad, for example, and how?

Different email addresses on devices, does it affect functionality? Can I change the address on iPad, for example, to the same as on iPhone, and how?

The nature of your problem is not entirely clear - perhaps due to limitations in the software used to translate your post from Finnish 🇫🇮 to English 🇬🇧🇺🇸.

Perhaps you refer to the AppleID that you have used to sign-in to iCloud and other Apple services - your AppleID (also known as your Apple Account) is usually identified with your preferred email address.

It is generally recommended that you use the same AppleID with all of your Apple devices - as this allows you to easily synchronise data between your iPad, iPhone and Mac computers. When using the same AppleID, all purchased Apps and Apple subscription services are available to all of your devices without having to purchase Apps and subscription services more than once.

If instead your issue relates to email - and you wish to have access to the same email accounts on all of your devices, you may simply need to add any accounts that are not currently configured to the devices as needed.

Please try to clarify the nature of the problem. With a better understanding of precisely where you need help, I can try to provide appropriate guidance - without overwhelming you with information that is irrelevant to your need.

Ongelmasi luonne ei ole täysin selvä - ehkä se johtuu ohjelmiston rajoituksista, joilla viestisi on käännetty suomesta 🇫🇮 englanniksi 🇬🇧🇺🇸.

Ehkä viittaat AppleID:hen, jota olet käyttänyt kirjautuessasi sisään iCloudiin ja muihin Applen palveluihin – AppleID-tunnuksesi (tunnetaan myös nimellä Apple-tili) tunnistetaan yleensä ensisijaisella sähköpostiosoitteellasi.

Yleisesti suositellaan, että käytät samaa AppleID-tunnusta kaikissa Apple-laitteissasi, sillä näin voit helposti synkronoida tiedot iPadin, iPhonen ja Mac-tietokoneiden välillä. Kun käytät samaa AppleID:tä, kaikki ostetut sovellukset ja Applen tilauspalvelut ovat kaikkien laitteidesi saatavilla ilman, että sinun tarvitsee ostaa sovelluksia ja tilauspalveluita useammin kuin kerran.

Jos ongelmasi liittyy sen sijaan sähköpostiin - ja haluat käyttää samoja sähköpostitilejä kaikilla laitteillasi, sinun on ehkä yksinkertaisesti lisättävä laitteisiin tilit, joita ei ole tällä hetkellä määritetty.

Yritä selventää ongelman luonnetta. Ymmärtäen paremmin, missä tarvitset apua, voin yrittää antaa asianmukaista ohjausta – ilman, että tukahdutan sinua tarpeellesi epäolennaisilla tiedoilla.
