I keep getting the following message: "imessage activation could not sign in please check your network connection and try again". I've done some searching here and followed links/instructions in other posts relating to imessage problems but nothing helps.  What can I do??

When you set up your iPhone for the first time you are asked to sign in with your Apple ID. The same process is important for all the applications that you are going to use on your device including iMessages, FaceTime and many more. Once you sign in with the ID you will not have to repeat the process again because the software will automatically manage it. However, sometimes you can’t sign into iMessage account. It is truly happenes in iOS 11.2.1.  Here are some of the solutions that might help.

Way 1. Check the Apple ID

The first thing you have to do is to check your Apple ID. Make sure that the ID and password you are entering is correct. You should access the Apple ID account page and enter the ID and password you were using on the iMessage. In case that it sign incorrectly you have to follow the given instructions.

Way 2. Check 3rd-party App

Most of the individuals make the mistake of downloading the 3rd party software like VPN, firewall or security. They do not check the specifications of the software and it might have been blocking the network ports of iMessages to provide you the required security.

In this situation, you have to assure that the ports are not blocked or you can disable the application to sign in to your account.
