Receiving text messages late?

I have an Iphone 5 and sometimes I receive my messages late. When I'm just scrolling on facebook on my phone or something then suddenly I get a notification that I got a text message like 30 minutes ago, sometimes more, sometimes less. But thats the first notification I get from it. Is this a problem in my phone or is it network sided? Any help is appreciated!

Greetings.

Well there's a chance that it could just be your internet connection. It depends if you're running on 4G, 3G, etc. Or maybe your Wi-Fi. Sometimes ill have a full 3 bars on my iPhone but still get texts a little late. But i'm not 100% sure.

P.S
Sorry for all the tech talk lol

  • Why is my iphone receiving texts late? I keep getting texts late, and i realized that as soon as i get home everyday (once i get into wi-fi signal) i receive text messages that people sent me from all throughout the day. Now it's not all my texts but i think i receive texts late from people with iphones. What is this problem and is there a way to fix it?
  • Why is my iPhone 5 receiving messages late? So I've recently gotten a T-mobile iPhone 5 & it's been fine the first month but outta no where my messages started to come in late. Sometimes 2-3 hours later. I tried everything from soft and hard reset. Anyone know the problem or how I can fix this? Is it the phone, or service problem?
  • Why is my iPhone 4 receiving text messages late? I have an iPhone 4, I've had it for just a year. The past month or so, sometimes I'll receive a message. However, when I check the time it was received, it was usually 5 or 10 minutes ago, today I just got one from 18 minutes ago and it only just notified me now. It's starting to bug me a lot, can anyone tell me how to resolve this problem? The phone is also running the most current software, I always do updates (even though it steals all of my storage, grrr).
  • Why does my iPhone receive messages late when I'm in a group text? I have the iPhone 4s with 16g (I have less than a gig left of space) and am on T-Mobile. Every single time I'm added to a new group text, my phone delays all messages sent to me. Regardless of whether it's another iPhone or if they're on the same carrier as me, none of my messages get to me until an hour or so later. Is it because I'm low on space? Or is it T-Mobile (probably the worst carrier I've ever had by the way)? Or is it the iPhone software?
