SendHub is a site I've covered before that is ideal for creating another line for your phone for free. This is great for education as it allows teachers to send texts to groups of students, parents, etc for free from any online device.
Here is more detailed info from a recent email...
"SendHub is a simple and fast way for professionals to communicate;
providing businesses, and organizations, with a call and messaging
solution to reach small and large groups of people. Their simple
interface lets users place & accept calls, as well as send group
messages to everyone, from anywhere. SendHub was founded for teachers,
but has also seen successful usage from businesses, political
organizations, faith groups and more."
I highly recommend checking out SendHub by clicking here!!
