There are many different methods of communication and collaboration available to students. The best method for you and your group will be the method members are willing and able to use consistently.
Discuss and agree on a method within your group at the beginning of the project/assignment.
Using email might be the least complicated way to stay in touch, especially if you start with a group email (including all group members) and then always "reply all" to keep an ongoing email chain going.
Some students prefer texting over email, and it can work fine as a primary means of communication if a group text is used AND all group members agree to use it.
If you haven't used OneDrive before to save files, it is available with the other Office apps once you're logged in to your school email.
Google has multiple apps that allow varying degrees of communication and collaboration. Although a Gmail account is required, Gmail accounts are free to create (and many students already have them).
