Problem 1: iPhone 7 not receiving all SMS, group message, getting delayed messages

Good afternoon. I have a relatively new iPhone 7 that was purchased in only September. In group texts that include both iPhone and non-iPhone users, I can send messages and everyone receives but more often than not, I do not get any of the responses. Other members of the chat have to screenshot their phone and send them to me so I can see the responses. On some occasions, I will get over 180 texts at once which are the responses and messages from the previous 4 days or I don’t ever receive them at all. I have tried turning on and off the Cellular data per an Apple recommendation. I have reset my network settings. I have reset all settings. I have obviously confirmed that my group messages SMS and MMS are all activated. This happens on my previous phone as well towards the end so I know it is not the physical phone. Any recommendations to this? — Mike Williamson

Solution: Hi Mike. This may be a network issue. The circumstances in this case, especially since the same exact problem occurred in another device presumably with your same account (number), point to that. By network issue, we mean to say that your carrier’s system is having some problems transmitting your messages from time to time. You must talk to them about this so they can look into it. There may or may not be an effective solution for the situation though. Still, it’s still worth mentioning that the issue occurred in at least two of your devices so they can check your account logs.

Problem 2: Verizon iPhone 7 new blank messaging window pops up when selecting contact from Favorites list, iPhone 7 update issues

I have updated my iPhone to the latest iOS 11.1.1 version. But since 11.0.3 my text messaging app has been problematic. When I chose a person to contact from my favorites by tapping the blue messaging bubble, a new BLANK messaging window opens. Then I have to tap the COMPOSE icon on the screen and type the contact’s name again. Then all the previous group chats and threads with that contact’s name appears, even though I never saved them. So then I have to scroll all the way down till I find the one contact I want to message. The same thing also happens when I use the messaging app directly from my home screen. Messaging works, but it’s a lot of steps to go through to find the person I want to message.

I have spoken to Apple support numerous times and have rebooted the phone and even performed a total wipe and reinstall. But nothing changed. Finally a supervisor tried to help and worked on the problem. She discovered that it is a carrier problem. Many people on VERIZON have the same issue. There was nothing she could do for me after hours of trying to correct the problem. — Kit

Solution: Hi Kit. Operating systems and apps are not perfect. Even though experienced and well-funded developers like those from Apple and from carriers try their best to polish their products before releasing them, bugs or glitches such as the one you’re experiencing can still happen from time to time. If an Apple representative has isolated the problem to carrier glitch, that means that it’s a coding issue. There must be an unforeseen code that may be missing, had been added, or not compatible with other systems. This happens all the time, especially since operating systems like iOS are regularly evolving. The best thing that you can do right now is to contact Verizon and report the bug to them. There may or may not be an immediate fix to the problem so what you can then do is to simply wait. Remember, the more users report the same exact bug, the higher the chance that developers will notice it. Everytime you report a bug, a ticket will be created for it so be sure to include all relevant information a developer may need. In this case, be sure to mention your particular phone model, operating system version, name of the app, and a good description of the symptom/s.

We are yet to receive reports of the same nature from other iPhone 7 users from Verizon but we will also be collecting data to aid us in finding ways to fix it. We will update this post accordingly if we’ll be able to come up with a solution.

Problem 3: iPhone 7 not detecting any SIM card

Hello! I’m a long term traveler, I’ve been traveling for 7+ months with my iPhone 6. AT&T unlocked the phone for me when I left and I’ve used different SIM cards in different countries with no problems. For reasons I can’t understand, I got a new SIM card same as usual, but now no SIM cards will work with my phone. I’ve tried different SIM cards and different countries but no one can figure it out. I updated to the new iOS 11.02 hoping that might fix some bug but no luck. I’ve rebooted, reset all settings, turned on and off but alas now I’m at a loss. The last cell phone place I took it to, the Malaysian guy told me he thought maybe it became locked again and he tried to unlock it but it is unlocked. He said it could be an antenna malfunction?

I’ve had the phone for 2 years so maybe it’s just the end of the line? I’m out of options and as a girl traveling solo I would feel so much safer if I just had a working SIM with me for emergencies. Any help would be greatly appreciated. Skyler in Kuala Lumpur *But originally from Texas 🙂 — Skylersnowlewis

Solution: Hi Skylersnowlewis. Does your iPhone still detects any other SIM card, like the original SIM card from your home network in Texas? In other words, does the phone still shows that it’s reading a SIM card when you insert it (eventhough it may say it’s out of coverage area)? If it does, it’s possible that some software settings may have been changed in your device that prevents it from reading third party SIM cards.

On the other hand, if your iPhone does not seem to show any indication that it’s detecting any SIM card, even when using the US SIM, that may suggest that your phone’s SIM card slot may be defective. Try pressing the SIM card when it’s in the slot to put pressure on the card and metallic contact beneath it. Otherwise, have the phone repaired for a possible SIM card slot problem.

Problem 4: iPhone 7 can’t receive messages but other devices can

Hi. I upgraded from iPhone 6 to 7 this week and have had 2 incidences of just not receiving texts. One actually showed up on my laptop as an iMessage but not on my phone. The same individual sent me another text later and it came through. Then last night..received 3 texts in a row from my son, to me and his dad (group)- the first text to me did not come through but the others did. It is not very comforting to think I am not receiving texts. Thoughts? — Margaretta Page

Solution: Hi Margaretta. It’s possible that you may have nominated your Apple ID to receive text messages instead of your phone number. This may be the reason why your Mac or laptop received your messages but not your phone.

To check if your phone number is set to send and receive text messages, do the following steps:

  1. Open Settings app.
  2. Tap Messages.
  3. Tap Send & Receive.

If you can’t see your phone number, try to link your iPhone number to your Apple ID. This will allow you to send and receive iMessages in your iPhone 7. To associate your phone number to your Apple ID, follow these steps:

  1. Open Settings app.
  2. Tap Messages and turn on iMessage.
  3. Tap Send & Receive. If you see “Use your Apple ID for iMessage,” tap it and sign in with the same Apple ID that you use on your Mac, iPad, and iPod touch.
  4. In the “You can be reached” section, make sure that there are checkmarks beside your phone number and Apple ID.
  5. Go to Settings > FaceTime and follow the same steps.
