My wife and I both have an iPhone 16 Pro, and ever since updating to iOS 27, iMessage has been a nightmare.
We’ve repeatedly experienced situations where I send her a message and it shows as “Delivered” on my end, but she never receives it. The same thing happens in reverse. Text messages, voice messages, photos, and other content randomly fail to arrive for either of us.
Another frustrating issue is that messages sometimes don’t come through at all, only for 4 or 5 of them to suddenly arrive at once, sometimes long after they were sent.
At first, I thought it was an internet connectivity issue, but I tested WhatsApp under the same conditions, and everything works perfectly. What makes this even stranger is that it happens even when my iPhone shows a strong 5G+ cellular connection.
Has anyone else been experiencing similar issues with iMessage since updating to iOS 27? Is this a known software bug, or have you found a workaround? It’s becoming really frustrating not being able to rely on something as basic as message delivery, especially when iMessage explicitly says the messages have been delivered.
