Quick Answer: When iPhone texts won’t deliver to an Android phone, the single most common cause is that the Android user previously owned an iPhone and their number is still registered to iMessage — your texts route to a dead iMessage account instead of their phone. The fix: they visit Apple’s official Deregister iMessage page and remove their number. On your side, make sure Send as SMS / Retry as Text Message is on (Settings → Apps → Messages), MMS Messaging is enabled, and — for photos — cellular data is on, because MMS can’t travel over Wi-Fi.
Your texts reach every iPhone flawlessly, but one Android friend swears they’re getting nothing — or your messages to them show “Not Delivered” in angry red. Green-bubble land suddenly feels like another planet.
Texts to Android travel a completely different road than texts to iPhones: instead of Apple’s internet-based iMessage, they go as SMS/MMS (or RCS) through your carrier. That road has its own tolls — and one famous trap: numbers that once belonged to an iPhone can stay registered to iMessage, silently swallowing every text other iPhones send them. The eight fixes below cover both your side and theirs.

How to Fix iPhone Texts Not Delivering to Android
Fix 1: The Stuck-in-iMessage Trap — the #1 Cause
If the recipient ever owned an iPhone, start here. When someone switches to Android without turning iMessage off first, Apple’s servers keep their number registered — and every iPhone (yours included) keeps sending their texts to a dead iMessage inbox.
- Ask them to visit Apple’s official Deregister iMessage page (search “deregister iMessage” — it’s on apple.com), enter their number, and confirm with the code they receive.
- If they still have the old iPhone: turning iMessage off in its settings (with the SIM still in) does the same job.
- This fixes their texting with every iPhone user, not just you — they’re likely missing texts from all their iPhone contacts right now.
- On your side afterwards: delete the old conversation thread and start fresh, so Messages re-checks how to route them.
Fix 2: Turn On the SMS Fallback
Your iPhone needs permission to drop from iMessage to plain SMS when needed.
- Settings → Apps → Messages → enable Send as SMS (newer iOS versions call it Retry as Text Message — “if iMessage or RCS is unavailable, send as text”).
- Manual fallback for a stuck message: long-press the failed message → Send as Text Message.
Fix 3: MMS Rules — Photos Need Cellular Data
The technical detail that solves half these cases: MMS cannot travel over Wi-Fi. Photos, videos, and group texts to Android go as MMS through the cellular data channel.
- Settings → Apps → Messages → enable MMS Messaging and Group Messaging.
- Settings → Cellular → make sure Cellular Data is on — even if you’re sitting on Wi-Fi. With data off, plain texts deliver but every photo to Android fails.
- Plain SMS, meanwhile, needs a voice-network signal — check your bars.
Fix 4: Check Blocks and the Number Format
The mundane causes worth thirty seconds.
- Settings → Apps → Messages → Blocked Contacts — confirm they’re not on it (blocks are silent in both directions).
- Check the saved number: it should be the full mobile number, ideally with country code (e.g., +92… / +1…). A landline or a mistyped digit produces eternal “Not Delivered”.
- Ask them to check their blocked list and spam folder too — Android’s Messages app auto-filters aggressively.
Fix 5: Toggle iMessage and RCS Off/On
Re-registering the messaging services clears routing confusion on your side.
- Settings → Apps → Messages → turn iMessage off, and toggle RCS Messaging off too if present.
- Restart the iPhone, then turn both back on and give them a few minutes to activate.
- RCS (the modern iPhone↔Android bridge with typing indicators and full-quality photos) requires carrier support — if the toggle is missing, your carrier hasn’t enabled it yet.
Fix 6: Restart and Update
- Restart the iPhone — stuck messaging sessions die with it.
- Settings → General → Software Update — Apple has shipped multiple fixes for iPhone↔Android messaging (especially around RCS) in iOS updates; being current matters more here than usual.
Fix 7: Reset Network Settings
The deep clean for messaging routes.
- Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings.
- Wi-Fi passwords will need re-entering; messages and contacts are safe.
- Test with a fresh thread to the Android contact.
Fix 8: Call the Carrier — SMS Is Their Service
Unlike iMessage, SMS and MMS are carrier-provided — when they break beyond your settings, only the carrier can fix them.
- Ask them to confirm SMS and MMS are provisioned on your line, and that no plan limitation or block on cross-network texting exists.
- Also update carrier settings first: Settings → General → About, wait ~30 seconds, install any pop-up.
- If you recently ported your number in, confirm the port fully completed — half-finished ports deliver calls but lose texts.
Still Not Delivering?
- Test the direction: have the Android user text you first, then reply inside that thread. If replies deliver but fresh threads don’t, the routing cache was the problem — deleting the old conversation (Fix 1, step 4) resets it.
- The Android side has its own checklist — their signal, their spam filter, their app updates. Our Android texts not working guide is the one to send them.
- Group chats with mixed phones: one member with broken MMS breaks the thread for everyone. If group texts specifically fail, every member needs MMS/Group Messaging on — or move the group to WhatsApp, where platform differences vanish.
- Both directions broken with everyone? That’s bigger than the Android bridge — work through our iPhone not receiving texts guide for the full network-and-carrier sweep.

Frequently Asked Questions
Why do my iPhone texts fail only to Android phones?
Texts to Android travel as SMS/MMS (or RCS) through your carrier rather than Apple’s iMessage. Failures point to SMS fallback being off, MMS lacking cellular data, carrier provisioning — or the recipient’s number being stuck in iMessage from a previous iPhone.
What does it mean when a number is “stuck in iMessage”?
When someone switches from iPhone to Android without disabling iMessage, Apple’s servers keep routing texts from iPhones to their dead iMessage account. They fix it in two minutes on Apple’s Deregister iMessage page — and it restores their texting with every iPhone user.
Why do plain texts deliver to Android but photos fail?
Photos go as MMS, and MMS requires cellular data — it cannot travel over Wi-Fi. Enable MMS Messaging in Messages settings and make sure Cellular Data is on, even when connected to Wi-Fi.
Does RCS fix iPhone-to-Android texting?
Largely, yes — modern iOS supports RCS, which brings internet-based delivery, typing indicators, and full-quality media to Android chats. It needs carrier support and the RCS toggle enabled in Messages settings on both ends.
Why does my message say “Delivered” but they never got it?
“Delivered” to a number stuck in iMessage means it reached the dead iMessage account, not their Android. Deregistering the number from iMessage stops the false deliveries and routes texts to their actual phone.
