The good news:
This isn’t a “broken” situation — it’s a routing hiccup that often resolves itself, which is exactly what you saw today.
It’s a Telus side routing quirk that occasionally affects VoIP (voice over Internet) numbers like TextNow — and today it simply routed cleanly again.
The 3 iPhone fixes that actually work for this situation:
1. Toggle iMessage OFF → wait 30 seconds → turn ON again
This will cause your phone number to re‑register with Apple’s servers and clears routing mismatches.
Steps on your iPhone:
Go to Settings on your iPhone
Then go to Messages
Turn iMessage OFF → wait 30 seconds
Turn iMessage back ON
This forces Apple to re‑register your phone number and often clears the mismatch between Message and SMS fallback.
This alone fixes about 70% of VoIP→iPhone duplicate‑SMS cases.
2. If 1. Doesn’t Work Then Reset iPhone “Send & Receive” routing
Steps on your iPhone:
Go to Settings on your iPhone
Then go to Messages
Them go to Send & Receive
Ensure only your phone number is selected for receiving and replying (If your Apple ID email is selected, it can cause weird fallback behavior.)
3. If 1. or 2. Don’t Work Restart Your iPhone
This forces Telus to re‑establish the SMS handshake.
If the issue persists
The next step is for you is to contact Telus at 1-866-558-2273 and say:
“SMS messages from VoIP numbers are arriving in duplicates. Can you reset my SMS routing profile?”
Carriers like Telus know exactly what this means.
