Apple’s iPhone 12 series has been on the market for more than a month. Being the first generation of 5G-enabled smartphones from Apple, the success is still not small. However, after the “green screen door”, the iPhone 12 flipped over again and many users reported Mobile phone network services are being phased out, including 5G and LTE, and users take full advantage of it during driving or traveling.

Judging by your description, it appears that the iPhone 12 series has a problem in the process of changing the towers. The user said that the iPhone 12 Pro encountered a problem that the network cannot take effect after activation. The only way to get it is to turn airplane mode on and off.
The cellular mode of the iPhone is automatic 5G. Moving on to the LTE test, the result is the same and the network settings are the same again The user resets the iPhone and reinstalls everything from scratch (not from the saved backup), but still fails.
Many people have complained about this: Although the iPhone 12 series uses Qualcomm’s baseband, the actual signal performance has always been poor and the loss of the network on the mobile phone made them very uncomfortable.
But it’s not impossible. There are also intelligent people. After asking for help from Apple’s technical support, they remotely installed two configuration files “baseband” and “phone record” (CFNetwork Diagnostics) on their mobile phones, which can temporarily fix this problem, but Apple has not officially responded at this time. , but home users still don’t care too much, the Bank of China’s iPhone 12 seems to be quite harmonious on the signal issue.
