iPhone 15 Specific eSIM Features

Dynamic Island and Dual SIM

iPhone 15 Pro and Pro Max feature Dynamic Island — it displays active call information from either SIM line, clearly indicating which number is being used for each call.

iOS 17/18 Dual SIM Improvements

  • Clearer SIM indicator in status bar — shows both SIM lines simultaneously
  • Per-app cellular data selection — assign specific apps to use specific SIM line
  • Contact-level line assignment — specific contacts always called from specific line

eSIM and Apple Watch Cellular

If you have an Apple Watch with cellular, it uses your iPhone’s primary cellular line. eSIM on iPhone 15 does not affect Apple Watch cellular functionality.

iPhone 15 Pro USB-C and eSIM

iPhone 15 Pro introduced USB-C. This does not affect eSIM functionality — eSIM works identically across all iPhone 15 models regardless of connector type.


Managing eSIM Profiles on iPhone 15

View All eSIM Profiles

Settings → Cellular → scroll down to see all stored eSIM profiles

Switch Active eSIM Profile

  1. Settings → Cellular
  2. Tap the eSIM profile you want to activate
  3. Toggle Turn On This Line
  4. Confirm — iOS deactivates previous eSIM and activates selected one

Delete eSIM Profile

  1. Settings → Cellular

  3. Tap Delete eSIM
  4. Confirm deletion

Important: Deletion is permanent on device. Contact carrier to re-issue before deleting active paid plans.


Common eSIM Problems on iPhone 15 and Fixes

“Add eSIM” option not visible

Fix 1: Update iOS to the latest version — Settings → General → Software Update.
Fix 2: Check Settings → General → About for EID — if missing, contact Apple Support.
Fix 3: If purchased from an unauthorized reseller, the phone may be carrier-locked — contact Apple or the original carrier.

QR code scan fails on iPhone 15

Fix: Ensure QR code display is at maximum brightness. Clean iPhone 15 camera lens. Use manual activation code as alternative — tap “Enter Details Manually.”

eSIM downloads but activation fails

Fix: Restart iPhone 15 after download attempt. Try again with fresh QR code from carrier. Contact carrier if repeated failures — they may need to re-generate QR code.

“Could not finish setting up eSIM” error

Fix: This usually indicates a carrier-side issue. Call carrier (Jio: 199, Airtel: 121, Vi: 199) — provide EID and request fresh activation. Carrier re-pushes profile to your iPhone.

Cellular data not working after eSIM activation.

Fix 1: Settings → Cellular → Cellular Data → confirm the correct line is selected.
Fix 2: Settings → Cellular → Cellular Data Options → check APN settings — usually auto-configured but may need manual entry for some carriers.
Fix 3: Toggle Airplane Mode on and off to force network re-registration.

eSIM line shows “No Service”

Fix: Toggle the eSIM line off and on in Settings → Cellular → tap the eSIM → Turn Line Off → Turn Line On. Wait 2 minutes for network registration.

OTP not received during Jio/Airtel activation

Fix: Physical SIM must have an active signal during eSIM activation. OTP goes to registered number via physical SIM — ensure Jio or Airtel SIM has network coverage before starting.

Both SIMs showing but calls only working on one.

F.: Settings → Cellular → Default Voice Line → ensure correct line selected. Also check that the non-default line is enabled and shows signal bars.

Jio charges approximately ₹10–₹25 for eSIM issuance. Airtel charges a nominal SIM replacement fee. Your existing recharge balance and plan remain unaffected.
