i transfer my data from iphone 11 pro to iPhone 7

Hi AMINDHIB,

The support article If you can't activate your iPhone or iPad (Wi-Fi + Cellular) contains steps you may find helpful as it relates to the specific message that you're seeing on the iPhone 7.

It's also worth pointing out that the iPhone 7 does not support eSIM but your iPhone 11 may depending on where it was purchased. If you used an eSIM on the iPhone 11 it would be necessary to contact your cellular provider to obtain a nano-SIM card programmed for your cellular account to insert into the iPhone 7 so that it can establish cellular connection which may be a requirement for activation to complete.

Regards.
