Have you ever encountered a situation where your iPhone shows all 5G signal waves but Facebook, Zalo, TikTok and YouTube all freeze, while the person next to you is still running smoothly?
Many iPhone users often think that when the device shows full 5G signal, the internet connection is definitely working normally. However, the reality is completely different. There are many cases where the iPhone displays a strong signal but mobile data is interrupted, causing messages to fail to be sent, videos to download and websites to cycle continuously.
It is worth noting that this error does not necessarily come from the iPhone hardware or the iOS operating system. In many cases, the cause lies in the connection process between the device and the carrier's network.

Summary
Many people hastily conclude that the iPhone has poor signal reception when they see that the device shows 5G but cannot access the internet. In fact, this is usually a connection error between the phone and the mobile network or a problem from the network operator.
Before thinking about repairing or changing to a new phone, try turning on airplane mode for about 15 seconds and then reconnecting. Just a small operation can sometimes help the iPhone work normally again in a few seconds.
