When I turn my iPhone off I don't receive any messages when I turn it back on?

My iPhones been like this for a while. I'll turn it off and say my friend will text me, when I turn it back on I won't get any of the messages. Anyone know how to fix this?

You need to call your provider and have them send a refresh to the switches. Might be a good idea to perform a service update as well.

Don't turn it off?

Getting messages after a phone has been turned off and on is hit or miss depending on where the messages are coming from. Some carriers may limit the window to have messages delivered to hours whereas others could be as much as a week. If that's the case there's nothing you could do.

  • Will I receive all missed text messages once my service is back on? My parents temporarily cut off my phone service (AT&T iPhone). When they turn it back on, should I receive all missed texts from when it was off?
  • Will a person receive text messages on iPhone once they power phone back on? When I text a friend of mine, sometimes their texts show up green when I text him (we both have iPhones and messages are normally blue)… Once their phone gets powered back on will the text messages I send when the phone is off b received once the phone is turned back on?
  • Why don't I receive messages unless my cellular data is on? I got this iPhone 3 months ago. It's the 5th one. This constant problem is that sometimes I don't get messages unless my Cellular data is turned on. I need to fix this cause its really annoying. Like for example 10 ppl texted me on Christmas Day saying merry Christmas. On January 4 I turned on cellular data while in my car & then I got them all! And it's crazy because It had the date of Christmas & the exact time.
  • Why don't I receive alerts or a notification when I receive a text and I already checked my settings? I adjusted my setting and even put the ringer and notifications on and put the volume and ringer on and I receive no alert, no pop up, alert or notification when someone texts me. Why? This is the iPhone X! I went to the cell phone/ carrier store and they didn't help me. They said to go to the apple store or check the settings. I already adjusted the settings. So what do I do now?
