Thank you for the confirmation xxxx! We will be conducting some basic troubleshooting which will include a temporary suspension of line 1558. There's no need to worry as we will promptly restore the line and this process will not incur any fees. Following this, we will refresh line 1558 to improve its coverage then we will provide the steps to process a Reset network setting and restart the device afterwards.

Please be advised that Resetting network settings essentially means reverting all your network-related settings back to their original factory defaults. This process can help resolve any issues that might have been caused by incorrect or corrupted network settings. However, please note that this action will disconnect you from any network you're currently connected to and you will need to re-enter your Wi-Fi passwords. Could you confirm if you've successfully completed the network settings reset and if it has improved your connection?
