iPhone 4 occasionally not receiving messages from one iPhone 4s

More than likely her phone is still sending as an iMessage to your device when you are out of wifi range and the message never gets delivered.

To prove that theory have her compose a message to you when you are out of wifi range and then when she clicks into the message area to type the text (just click in that box, don't type anything) does it says "iMessage" or "text message" in the box?

Basically if it says "iMessage" the iMessage servers don't know your phone has gone out of range of wifi.

If I were you I would just disable iMessage all together and just text since you dont have a data plan.

HI Friend,

Try to unsign and sign in again.

For FaceTime and iMessage chosse to use your email address instead of your mobile number.

Go to Settings>>Message>>Send&Receive and set your email address.

If it is still not working, unsign your Apple ID and select your mobile number ("+" "country code" "mobile number").

Turn off Show Subject in Settings>>Message

Reset the Network Setting, which makes your phone to forget every networks and passwords that you connected your phone to.

to reset the Network Settings just go to Settings - General - Reset (at the bottom) - Reset Network Settings.

I remember when I reset the Network Settings, i turned off iMessages. I connected to my home Wi-Fi and surfed the web for a little while. Sent some regular SMS messages, and about 10min later, I turned on iMessages again and sent a text to a friend with an iPhone and it started working as iMessage! Baloons finally became blue.

Go to www.apple.com or Settings>>iCloud then access your Apple ID. There you can edit your information, placing your phone number and tap OK. then go to iMessage settings and mark your phone number to receive iMessages.

Also check in: Settings>>Message if you turned on iMessage before. Here, turn off "Show Subject Field".

Change your address for your currently location. If not works, change it for your native country.

Did you turn on iCloud as well?

Sorry CoolHand but that is incorrect....

It doesn't matter if the phone is not on Wifi at the time the message is sent....it will get delivered once it is.

Cheers,

Hi Bryantdl7,

Take a look at this Messages troubleshooting article. Any chance your friend has downloaded an (unnecessary, and probably harmful) Anti Virus software? Are all other messages that your friend is sending being received byt the recipients? Is it just your phone that is not getting them? Has your friend tried signing out of Messages and back in? Just some thoughts....

Here's the article:

Odd, if my data is off and I connect to WIFI or turn my data back on I never get the imessages sent to me when data was off. My friends and spouse with and iPhones tell me the same happens to them.

Thanks for posting back Bryantdl,

Great news! Glad you got it sorted! 🙂

Cheers,
