How to improve iPhone dual-SIM signal: update to iOS 15.5!

Everyone is familiar with iPhone signal problems. However, when we use iPhone dual SIM, we may encounter poor signal quality. So, can we only passively accept this situation? Is there a way to solve the iPhone dual-SIM signal problem?

#In fact, the main reason for poor iPhone signal is due to external baseband problems. In order to solve this problem, the best way is of course for Apple to upgrade the hardware, such as developing its own baseband. However, there is no sign of this improvement yet.

However, Apple is not sitting idly by and they have taken some measures to improve this problem. Recently, they pushed the iOS 15.5 Beta4 test version, which has optimized the signal. This means users may get better signal quality when using Apple devices. This is Apple’s positive response to user feedback and shows that they attach great importance to user experience. Through continuous improvement and optimization, Apple strives to ensure that users can enjoy the best device performance.

The update package size of iOS 15.5 Beta4 is 520M, and the version number is (19F5070b). Although iOS 15.5 Beta 4 mainly fixes bugs and optimizes the system, according to feedback from users who have already upgraded, the dual-SIM signal of the iPhone has been improved after the upgrade, and the situation of disconnection and network instability has been significantly improved.

Apple has upgraded the baseband firmware version of the iPhone 13 series from 1.59.03 to 1.61.00 in the first three beta versions of iOS 15.5. According to speculation, this upgrade may be to optimize the stability of the iPhone signal.

If your dual-SIM iPhone has poor signal, there is a solution at this stage. You can use Apple's mobile phone repair tool and upgrade to the iOS 15.5 Beta4 version, which can improve the problem of poor signal on dual-SIM iPhones.
