iPhone 17e indoor 5g signal reception problem

I am from India.My newly bought iPhone 17e frequently switches to LTE mode only on my ground floor of my house despite refreshing frequently 2 to 3 mins by toggling Airplane mode off/on and turning settings to “5g on” and “ allow more data on 5g” and reset network settings.But in my old iPhone 15,it’s all OK.Pls help

Because you moved your SIM from an iPhone 15 to an iPhone 17e, your carrier needs to update your device provisioning on their backend to recognize the new Apple modem that is included in your new iPhone

  • If using a Physical SIM: Go to your carrier's local store and ask for a fresh 5G-upgrade SIM card. Older SIM cards frequently struggle to maintain stable standalone (SA) 5G connections indoors on newer modems. 
  • If using an eSIM: Go to your carrier's self-care app or store, delete your current eSIM profile, and request a fresh eSIM activation for the iPhone 17e. A clean profile installation frequently resolves band-switching bugs.
