iMessage Waiting for Activation on iPhone After iOS 26 Update (Complete Fix Guide)

🗓️ November 24, 2025, By ✍️ Karly Wood

If your iPhone keeps showing “iMessage Waiting for Activation” after updating to iOS 26, you’re definitely not alone. Many U.S. users report that iMessage won’t turn on, stays stuck on activation, or glitches after updates. The good news? You can fix it in just a few simple steps.

Let’s break down everything you need to know.

Why iMessage Shows “Waiting for Activation”

Here are the most common causes:

  • Poor Wi-Fi or cellular connection
  • Apple ID not fully signed in
  • Incorrect date & time settings
  • Carrier is not allowing SMS activation
  • Pending carrier balance (for SMS activation fee)
  • iMessage server delays after iOS updates
  • Temporary Apple server outage
  • Using a VPN or a restricted network

How to Fix iMessage Waiting for Activation (iOS 26)

Follow these in order — most users fix it within Steps 1–4.

1. Check Your Internet Connection

iMessage needs a strong Wi-Fi or cellular connection to activate.

  • Turn Wi-Fi off → on
  • Try switching to cellular data
  • Restart your router if needed

Tip: Move near your router for a stronger signal.

2. Turn iMessage Off and On Again

  1. Open Settings
  2. Scroll to Apps
  3. Tap Messages
  4. Turn iMessage off
  5. Wait 10 seconds
  6. Turn iMessage on again

Activation should restart automatically.

3. Sign Out and Sign In to Apple ID

  1. Go to Settings > your name > Sign Out
  2. Restart iPhone
  3. Sign back in
  4. Open Settings > Apps > Messages > iMessage

This fixes Apple ID-related activation problems.

4. Set Date & Time to Automatic

Apple requires the correct time zone to verify activation.

  • Go to Settings > General > Date & Time
  • Turn on Set Automatically

5. Check “Send & Receive” Settings

  1. Go to Settings > Apps > Messages
  2. Tap Send & Receive
  3. Make sure your phone number is checked

If only email is selected, activation may fail.

6. Toggle Airplane Mode

  1. Turn on Airplane Mode
  2. Wait 10 seconds
  3. Turn it off
  4. Turn iMessage off → on

This refreshes the network and usually forces activation.

7. Restart Your iPhone

A simple restart clears system glitches after iOS updates.

8. Check Carrier Plan (VERY Important in the U.S.)

Your carrier must support SMS texting for activation.
iMessage activation uses a special SMS in the background.

Check your plan with:

  • AT&T
  • Verizon
  • T-Mobile
  • Boost / Metro / Cricket

If your number cannot send SMS, activation will fail.

9. Carrier Settings Update

  1. Go to Settings > General > About
  2. Wait 10 seconds
  3. If an update appears → tap Update

These updates fix texting and network problems.

10. Reset Network Settings

(Do this only if the above fails)

  • Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings

This resets Wi-Fi, network & iMessage settings — but does NOT delete data.
