Why is Apple s signal so bad, and why is Apple s phone signal bad?

Make sure you are within the coverage area of the cellular network. Then, follow these steps:

To turn cellular data on or off, go to Settings, then tap Cellular or Mobile Data. If you're using an iPad, you might see Settings > Cellular Data.

If you're traveling abroad, make sure your device is set up for data roaming. Go to Settings > Cellular> Cellular Data Options> Data Roaming.

2. Restart your iPhone or iPad

Restart your device, the network may be unavailable due to some apps!

3. Check if there is an update to the carrier settings.

To manually check for carrier settings updates and install them, follow these steps:

Make sure the device is connected to a Wi-Fi or cellular network.

Tap Settings> General> About This Mac. If an update is available, you'll see an option to update your carrier settings.

To see the version of carrier settings on your device, tap Settings > General > About This Mac, then look next to Carrier.

Apple's poor phone signal is something that the whole world knows.

Apple ditched Qualcomm baseband and began to switch to Intel baseband.

At the beginning of 2017, Apple and Qualcomm, two tech giants, broke off a patent war over patent fees. By the time of 2018, the iPhone XS has all used Intel baseband, and compared with Qualcomm baseband, the biggest problem with Intel's baseband is the signal!

In April last year, Apple and Qualcomm have reconciled, although the iPhone 11 series still uses Intel baseband, but also to give people some preparation time, if nothing else, this year's new iPhone will use Qualcomm baseband.

In fact, the signal of the iPhone has little to do with the system, although the system upgrade will be accompanied by the baseband update, but it is only optimized, and it mainly depends on the location of the phone, the network conditions and the baseband model.

Why is the iPhone signal poor? Here's why, you'll never be wrong when buying a phone!

There's really no way to do this, Intel's baseband is like this, there is really no good way, but in a normal environment, you can still use calls and Internet access normally, but in an environment where the signal coverage is not very good, it is not as good as an ordinary mobile phone of a few hundred dollars, iPhone12 has abandoned Intel baseband, if you can't stand it, then replace other brands of mobile phones or sell them as second-hand for iPhone12.

My mobile phone is a mobile card, and the signal is not enough in the subway, so my friend's telecom card will not be affected, it should be the reason for the card.

The iPhone's overly compact internal design makes it impossible to leave enough space for the signal antenna inside the iPhone, resulting in a significant reduction in the efficiency and area of the antenna to receive signals.

In single-SIM mode, although the signal quality of iPhone13 is not particularly strong, it is also at a medium level, and there is no pressure to play ** and surf the Internet, and there will be no malfunction.

However, in dual SIM mode, there will always be one card of the iPhone 13 that drops the chain, and the signal of the other card may be full, but there is no guarantee that both cards have high signal quality. As a simple example, if the iPhone 13 inserts a mobile card and a Unicom card at the same time, then it is very likely that the signal of the mobile card is full, while the signal of the Unicom card is very poor.

However, when the mobile card is removed, the signal of the Unicom card will return to the normal level, and the two cards cannot work at the same time. This may be the main reason for the poor signal of iPhone13, now there are more and more users who have two cards, and Apple's handling of dual SIM dual standby is not rigorous, so users mistakenly think that the signal of iPhone13 is too poor.

A bad cell phone signal can be due to the following:

1. The mobile phone is in the signal blind zone, which will cause the phenomenon of "not in the service area", "temporarily unreachable" or call interruption, which includes outside the network coverage area.

2. It is a bad signal caused by interference.

3. Disconnection caused by the failure of cross-zone switching.

4. Due to the temporary failure of the network, or the network is particularly busy, it will also cause the mobile phone signal to be poor.

5. The mobile phone card using the 2G network will also cause bad signal and other reasons.
