I have physical sim card with t mobile and get a new iphone14 with atnt. What should I do? I can’t transfer my current sim to my new phone

There are two issues:

1. If your phone is carrier-locked to AT&T, you will have to convince AT&T to release the carrier lock before you can switch to another carrier.
2. Once you get your phone unlocked (or verify that it is unlocked), you'll need to ask T-Mobile to give you an eSIM. iPhone 14 models sold in the U.S. take electronic SIMs (eSIMs), instead of physical SIM cards.

Carrier Lock:- Request your iPhone’s original Carrier to unlock your iPhone and if they agree and do it, then you may know the further process here --> How to unlock your iPhone for use with a different carrier ...

Transferring Between Cellular Providers:

Talk to AT&T. They perform the transfer of the eSIM card. As for transferring data, enable items in iCloud settings, and it should then be accessible through iCloud --not the iPhone itself.

Syncing Items Via iCloud:

As an example, here is how to do so for Photos:

I. On an iPhone:

Sync with iCloud, manually:

1. Go to: Settings
2. Tap: Your Name (Top Item)
3. Tap: iCloud
4. Tap: Photos
5. Enable: iCloud Photos

II. On a Mac:

Access from iCloud, manually:

1. Go To: icloud.com
2. Select: Photos
3. Download: the Photos
