Why does iphone 6 send text messages sometimes in blue and sometimes in green?

The green ones are normal short messages, which can be sent to any mobile phone, that is, short messages from ordinary communication companies.

The blue one is Apple's own iMessage, and those who need traffic are people who can send it to each other and Apple phones.

What are the common problems in using iPhone? ?

First, open the AppStore blank?

Solution: Change DNS or restart the phone.

Change DNS method:

Open the settings, click on Wi-Fi, click on the circular exclamation mark at the back of the homepage of Wi-Fi, click on the line of DNS, and enter 8.8.8.8 or14.16.5438+04.16.5438+06.5438+04.

Modifying DNS has no effect on mobile phones. If you want to restore, you only need to delete all the numbers in DNS, and automatically restore to the unmodified state after returning.

You can also set up-iTunes store and App Store, log out of your account, and then log in again.
