You move your number to a new phone, tell the family, and then… half your texts stop arriving. No error on your end. No error on theirs; their phone even says Delivered. Your new phone isn't misbehaving. Your number still remembers being an iPhone, and until you tell Apple and Google it left, their servers keep quietly accepting messages meant for you. Here's the five-minute fix.
Why do texts go missing after you leave an iPhone?
While your number lives on an iPhone, it gets registered with two chat services: iMessage and, on recent iPhones, RCS. Your friends' phones quietly look your number up before every message and, seeing those registrations, route their texts through those services instead of the ordinary phone network. That's what makes the bubbles blue, the photos sharp, the typing dots appear.
When your number moves to a phone that doesn't use those services, nobody tells them. Friends' phones keep routing the old way. The servers keep accepting messages on your behalf (which is why the sender sees "Delivered"), and the phone network never carries them to you. No bounce, no warning, nothing. The message simply goes to a phone that no longer exists.
Before you switch: three toggles on the old iPhone
Best done while your number is still on the iPhone. If you've already moved it, flip them anyway, then use the web tools in the next section.
1. Turn off iMessage. Open Settings, tap Apps, tap Messages, and turn off iMessage.
2. Turn off RCS. On the same Messages screen, tap RCS Messaging and turn it off. (Don't see it? Your carrier doesn't offer RCS on iPhone, so you can skip this step.)
3. Turn off FaceTime. Back in Settings, tap Apps, then FaceTime, and turn it off. Apple recommends this as the second half of the same clean exit.
Already switched, or the iPhone is gone?
For iMessage, Apple runs an official web tool: selfsolve.apple.com/deregister-imessage. Enter your number, and Apple texts you a confirmation code. It arrives as a plain text, so it will reach your new phone. Type it in, and the registration is removed. (Apple's own instructions live here.)
For RCS, there's no Apple web tool, but Google runs one at messages.google.com/disable-chat: enter your number and tap Deactivate. It was built for Android phones, but the major U.S. carriers run their RCS, including on iPhones, through the same underlying registration system, so it's a sensible belt-and-braces step. If it says your number isn't registered, that's good news: the toggle already did its job.
Apple says plain texting should work right away after deregistering, though it can take a few hours for every device to catch on. Give it a little time before you judge the results.
Group chats need one more nudge.
iPhones remember how they've been reaching you per conversation, and old threads can keep trying the old way long after your number has moved. Apple's own troubleshooting advice for stubborn group messages is simple: delete the conversation and start a new one. So for any group chat that predates your switch, ask someone to start the group fresh. That single step fixes most lingering weirdness.
Two settings on your family's iPhones make everything sturdier. Each lives at Settings → Apps → Messages:
Send as Text Message: turn it on. It tells their iPhone to fall back to ordinary texting whenever the chat services can't reach someone. It's the safety net for exactly this situation.
Group Messaging: make sure it's on, so groups travel as one shared conversation instead of splintering into separate one-on-one texts. (If it's missing, their carrier handles this automatically.)
And set one expectation kindly: your bubble turns green. Green just means ordinary texting, the kind every phone on earth speaks. Group photos sent this way arrive compressed, because carriers cap picture-message sizes (roughly 1 to 3.5 MB, depending on the carrier). For full-quality photos and videos, a WhatsApp or Signal group does it beautifully, and both live happily on a phone built for conversation instead of consumption.
The five-minute checklist
In order, with the old iPhone in hand if you still have it:
1. On the iPhone: Settings → Apps → Messages → iMessage off, and RCS Messaging off if it's there.
2. Settings → Apps → FaceTime → FaceTime off.
3. No iPhone anymore? Deregister iMessage at Apple's tool, and RCS at Google's.
4. Have someone restart any group chat that predates your switch.
5. Ask your closest people to turn on Send as Text Message on their iPhones.
That's it. Texts, pictures, and group chats all flow again, by the ordinary, dependable route.
Where Adesse comes in
Adesse is a premium smartphone that keeps everything a phone is for (calls, texts, group chats, maps, music, your camera, your bank) and quietly refuses the apps engineered to never let you go. Switching from an iPhone is a path we've walked ourselves; this checklist is part of how every Adesse phone gets set up.
We're honest about the trade-offs, too: iMessage is Apple-only, so chats with iPhone friends ride the green route. And the group chat still ends, like everything should.

How long does deregistration take to work?
Apple says plain texts should start arriving right away, though it can take a few hours for some devices to notice the change. If a friend's messages still aren't reaching you the next day, have them delete your old conversation and start a fresh one; their phone may be holding on to the old routing.
What happens to texts people sent before I fixed this?
They're gone, unfortunately. The old messaging service accepted them on your behalf, and there's no way to pull them back out. Once the fix is in, ask anyone important to resend, from a fresh conversation if the first try doesn't land.
Will I still be in group chats with iPhone friends?
Yes. The group turns green and travels as ordinary group texting, which every phone speaks. Someone may need to start the group fresh after you switch, and photos sent this way arrive compressed; that's a carrier limit, not a fault. For full-quality photos, a WhatsApp or Signal group does it beautifully.
Does this happen with every phone, or just Adesse?
Every phone that isn't an iPhone. The registrations belong to your phone number, not to any device. Anyone moving a number away from an iPhone walks through the same doorway, and the fix is the same five minutes either way.
