Using and XS/XR with iOS 12.0 (first release)?
If you see this message on your new iPhone XS, XS Max, or XR and it’s using iOS 12.0–update to iOS 12.1 (if available or you are a beta tester) or wait for that next update to get the supported dual SIM features and settings on your phone.
To check your iOS version, go to Settings > General > About and scroll down to version.
What’s an eSIM?
An eSIM is a digital SIM that allows you to activate a cellular plan from a carrier without having to use a physical SIM card. eSIMs are stored digitally on your iPhone–there is no physical card to insert.
That means you can have two different phone numbers (or data plans) on your iPhone XS or XR! Like one for home and one for work. Or one for domestic and one for international calling while traveling or away on business.
Using different mobile carriers?
To use two different carriers, your iPhone must be unlocked. If locked, both your physical SIM and eSIM must be from the same carrier.
However, if a CDMA carrier provides your first SIM, your second SIM won’t support CDMA.
Since both of your phone numbers can make and receive voice calls and texts, you need to specify your primary and secondary numbers on your iPhone.
Don’t use an eSIM or Dual-SIM but still see the message number changed to primary?
Even folks without iPhones that support eSIM or Dual-SIM sometimes see this message, as well as folks that have the capability but don’t use it.
If that’s you, remove your physical SIM card and then reinstall it. This usually does the trick!
Set-Up Primary and Secondary SIMs on Your iPhone 11, XS, or XR
Once you activate a second SIM or eSIM, you must label your plans and choose which one is your primary.
- For iOS 13+, Messages and FaceTime support two phone numbers and you can start a text message or FaceTime call from either number.
- For iOS 12,iMessage and FaceTime use your default line to call and send messages.
If using iOS 12.0 (Settings > General > About >Version,) you won’t see these options! Update to iOS 12.1 or above
Label Your SIM and eSiM
- Go to Settings > Cellular and tap the number to label it
- Tap Cellular Plan Label
- Select a prefilled label or create a custom label
Seeing Set Default Line Screen?
- For iOS 12, iMessage and FaceTime require you to set up your default number (iOS 13+ allows you to use both numbers for Messages and FaceTime)
- Choose your options
- Set Primary as default–voice, SMS, Data, iMessage, and FaceTime all use your primary number
- Use Secondary–voice, SMS, Data, iMessage, and FaceTime use your secondary number
- Set Secondary for Data only–keeps primary for voice, SMS, iMessage, and FaceTime but data uses your secondary number
To change which line iMessage & FaceTime Uses iOS 12
- Go to Settings > Messages.
- Tap iMessage & FaceTime Line
- Select which phone number you want to use for these services
Change Your Default Voice Line
- Tap Settings > Cellular > Default Voice Line
- Tap to change
Change your cellular data number
- Go to Settings > Cellular
- Tap Cellular Data
- Select which phone number you want to use for your data
Delete the message thread with the problem
If this issue shows up on just a few messages or a single message, try deleting that entire conversation or conversations where you see the “number changed to primary” error.
Then restart your device.
If you use Message in iCloud, deleting the message thread removes it from all devices signed in with the same Apple ID. You cannot recover these deleted messages.
If you set-up all your SIM and eSIM information and you still see this message, try resetting iMessage (or FaceTime)
- Go to Settings > Messages or Settings > FaceTime
- Toggle Off, wait 20-30 seconds, and toggle back on
If that doesn’t work
- Remove your phone number from iMessages
- On your iPhone, go to Settings > Messages > Send & Receive
- Select your Apple ID and tap Sign Out
- Then go to Settings > FaceTime, select your Apple ID and tap Sign Out
- Sign back into FaceTime and then iMessage with your Apple ID
Reset all settings
- This is usually the last resort since it resets all your personalized features back to factory defaults
- Go to Settings > General > Reset > Reset All
- This resets to default everything in Settings, including notifications, alerts, brightness, and clock settings like wake up alarms
- Resetting all settings also reverts all your personalized and customized features like wallpapers and accessibility settings back to factory defaults.
- Performing this action does not impact any of your personal device data, including photos, texts, documents, and other files
- You need to reconfigure these settings once your iPhone or iDevice restarts
- Just delete the message threads from the contacts that say “number changed to primary.” That message goes away and it didn’t come back for me!
- Go to Settings > Phone > My Number. Mine had a “+1”(country code for the USA) before the area code. I removed that country code so now my number only shows up as a nine-digit number. I just texted my wife; when I did, the one I sent still popped up “Number changed to primary”, but her reply and every reply sent back and forth since hasn’t had it anymore. So try removing your country code from all your phone numbers!
- Try a reset all settings. I didn’t want to delete any messages, so I gave this a try. And for me, it worked! You do have to take some time and readjust all your personalized settings like entering WiFi passcodes, ringtones, any accessibility features, alarms, and notifications and so forth. But this did the trick for me!
- Try deleting the message conversation with that problem from the person which you are seeing the ” number changed to primary “, then restart the phone–this is the only thing that worked for me
