iPhone 12 not receiving group texts

I've been struggling with the same issue on my iPhone 12 Pro on Verizon on a new SIM card. If the group text includes at least one non-iPhone user, some messages don't come through. It doesn't matter if it's coming via SMS or iMessage. My husband (iPhone XR) is in the same groups and receives all the messages without issue. I've noticed that, many times, images that are texted don't want to come through as well. So I get 6 responses about an image I haven't received! I've toggled things on and off, reset network settings, deleted the groups, etc. to no avail. So yeah, I'm super frustrated.

Upgraded from iPhone 11 Pro to iPhone 12 Pro. Verizon Business Account.

My 11 Pro (which was not experiencing this issue) was on iOS 14 but not 14.1, after setup was complete the 12 Pro was on 14.1.

Could be an issue with 14.1, could be an issue with 5G, could be another hardware issue with the 12s, or carriers are dropping the ball somewhere.

I'm a die-hard apple user, I will always buy the newest 'Pro' version of everything (luckily I have no need for a desktop or I'd be selling my left nut for a Mac Pro). I'm a huge advocate for Apple and all of their practices, so this issue is really ******* me off.

I've finally upgrade from a 7 plus to the 12 pro and then I started noticing I have the same issue. Normally happens when one or more friends in my group message has an android. I switched my old Tmobile sim card from my 7 plus to the new pro. Could that me the problem?

would this issue be fixed, then, if the phone had cellular data options set to LTE only for Voice&Data? I set my phone to LTE on the second day as T-Mobile 5G in my neighborhood is still slower than LTE. Still missing android messages in group messages though.

I talked to an Apple “senior advisor” yesterday and they had me turn on iCloud for “Messages.” They said it will take 24-48 hours but then it may solve the problem. I’m not sure if it has or not yet. Also seems like a big waste of storage. Maybe it’s just a temporary fix for now?

Et al.. Integrated messaging is a Verizon thing with their message+ app. (Please correct me if I'm wrong, but that's what I'm seeing.)

The issue is with ALL carriers.

Even if it worked on the verizon phone it still does not solve the overall problem that it is an issue after upgrading. I have a verizon phone and I do not use their message app. I don't want to. I should be able to use the iPhone app without issue.

By the way.. I've had icloud for message on and no dice. I did delete all my texts... turn off icloud for messaging and then turned it back on.

So far I saw some texts I was missing come back but still not sure if this fixed my issue or not or if I am still having the issue. Some of the texts I have missed are pretty important and found out via a phone call I didn't get them.

@tonybalon3y - actually this means it is likely not a sim issue causing the problem. For a lot of people, they had switched sims to fully support 5g - so the carriers as a last ditch effort will swap out the sim to make sure the new sim isn't the cause. But for you, since it is not a new sim and it was working just before your switch, it takes away another variable from the equation. Another variable is the IOS version. It is very likely you were not on the latest (IOS 14.1) when you switched (or if you had been on the latest, you would have only been on it for a few days at it was released just a couple days before the iPhone 12 and had just not noticed)

On T-mobile, as I understand it, the only thing that a new sim will give you is standalone 5g (which the iPhone 12 doesn't support yet anyway).

I am having the same issue but mostly with photos in a text from a non-iPhone user. Either direct texts messages or group texts. Nothing is coming through. I see other people in the group “liking” an image but I don’t actually see the image.

iPhone 12 Pro, iOS 14.1, AT&T

Once just one Android user is part of the group, all messages are sent as SMS and MMS. So the fact that the specific user in the group is a fellow iPhone user is irrelevant in the case of a mixed group. As I've stated in previous replies, SMS and MMS messages are handled by your carrier and are a feature of your wireless plan. So if they're not working, this is 99 times out of 100 a carrier side issue. Complain to them that it's not working.

I'm AT&T and have this same - very frustrating - issue... I get "some" but not all texts now in my group chats... Highly doubt it's AT&T - my guess is there will be an iOS update coming soon if this many people are having the same issue...

Just had my second call with Apple. They act like they have never heard of this problem. Had me do the typical things like reset network settings. They then told me my problem was solved. Waste of time. Hopefully update comes soon.

Brutal... This IS being monitored by Apple, I'm assuming... So at SOME point - we'll make some noise with them. Look - nothing can be perfect - bugs are expected... But listen to people calling and escalate the issue ASAP, Apple!!!

Apple support advisors don't generally follow the Apple support communities and aren't expected to do so. So them not being aware of this thread isn't surprising. Also, as I've repeated in several responses, SMS and MMS messaging is A CARRIER FEATURE. Complain to your carrier.

You are being needlessly dense.

First, no one is saying that Apple *support advisors* monitor these forums. But If I were an Apple engineer, I certainly would. I'm sure Apple has some way of tracking support calls from users to look for trends, but how long does it take for a trend to get noticed? Probably more time than if the engineers just came here.

Second, while you're not wrong that each carrier might have a way of individually fixing a setting (e.g., integrative message on vzw) that doesn't mean your response is helpful. It should NOT take each individual user impacted to call their carrier to ask them to fix it. In fact, what about all the people that AREN'T savy enough to come here to complain in search of a solution?

Your recommendation is that we all individually call our carriers to fix the issue. That advice is woefully unhelpful to the normal users out there. This issue quite obviously transcends hardware, software, and carriers. The issue should be worked by the least common denominator: Apple.
