Quick reference
Where is the IMEI on iPhone 15?
Settings → General → About → IMEI. Or dial *#06# from the Phone app. Or look on the SIM tray (eject with a paperclip from the right side). The IMEI is also printed on the original retail box.
How do I activate eSIM on iPhone 15?
Settings → Cellular → Add eSIM. Choose between transferring from another iPhone (fastest), scanning a QR code from your carrier, or entering activation details manually. iPhone 15 sold in the US is eSIM-only — no physical SIM tray. Most major US carriers support eSIM activation in their apps.
How do I check for iOS updates on iPhone 15?
Settings → General → Software Update. Tap "Update Now" if an update is available. Updates require Wi-Fi and battery above 50% (or plugged in). Apple typically releases major iOS updates each September and minor patches throughout the year.
How do I factory reset iPhone 15?
Settings → General → Transfer or Reset iPhone → Erase All Content and Settings. You will need your Apple ID password to disable Activation Lock. Back up to iCloud or your computer first; this is irreversible.
What carriers does iPhone 15 work on unlocked?
Unlocked iPhone 15 (Apple Store / Apple.com purchase) works on Verizon, T-Mobile, AT&T, and all MVNOs riding those networks (Mint, Visible, US Mobile, Cricket, etc.). It supports 5G sub-6 GHz on all three networks; mmWave 5G on Verizon and AT&T. Carrier-locked models from Verizon/T-Mobile/AT&T may need to be unlocked by the carrier first.
How do I transfer data from my old iPhone to iPhone 15?
During initial setup, choose "Transfer from iPhone" and bring both phones close together. Or use Quick Start: hold the old iPhone next to the new one, follow on-screen prompts. iCloud restore is the third option (slower, but works without the old phone). Plan ~30-60 minutes for the transfer; phones must be charged.
