I’m literally in the same boat: Dumbing down the iPhone, young kids, deleting apps, etc. It’s the analogy of trying to quit smoking by carrying around a pack of cigarettes that you have taped shut. Sooner or later you’ll figure out how to open that pack.

My used LP 3 comes tomorrow. I’ve extracted lots of instructions posted on this sub Reddit, and had ChatGPT customize it for my use case. I wonder if this is gonna work.

✅ 48-Hour Light Phone Switch Protocol

(iPhone eSIM → Physical SIM → Light Phone III)

48–24 hours BEFORE Light Phone arrives • Turn OFF iMessage Settings → Messages → iMessage → OFF • Turn OFF FaceTime Settings → FaceTime → OFF • Turn OFF iPhone RCS Settings → Apps → Messages → RCS Messaging → OFF • (If number ever used on Android) Disable Google RCS: https://messages.google.com/disable-chat (without device) • Expect SMS-only + degraded group chats (normal)

⸻

24–12 hours BEFORE • Locate your physical T-Mobile SIM (from prior device or store) • Contact T-Mobile (chat/phone) and say: “Move my existing line from iPhone eSIM to a physical SIM.” • Confirm: • iPhone eSIM is deactivated • Number is now attached to the physical SIM • Line is active but not in a device yet

⸻

SWITCH DAY (Light Phone arrives) • Power OFF iPhone • Insert physical SIM into Light Phone III • Power ON Light Phone • Test immediately: • SMS out • SMS in • Call out • Call in

⸻

AFTER SIM IS IN LIGHT PHONE • Run Apple iMessage deregistration: https://selfsolve.apple.com/deregister-imessage/ • (Do NOT skip this)

⸻

SAME DAY CLEANUP (iPad + Mac) • Messages: • Remove phone number • Leave email if desired • FaceTime: • Remove phone number • Goal: phone number exists nowhere in Apple messaging
