TextNow has a number of options for how you can reply to incoming messages. Here's where to find them, and what they mean:
Finding Your Quick Reply Settings:
1. Open your TextNow main menu by tapping on the main menu button , and then tap on the Settings button .
2. On your Settings page, tap on Messaging.
3. On the Messaging page, tap on Quick Reply.
That will open the Quick Reply page:
From here, you can turn on or off each option anytime.
Floating Chat: Chat "heads" overlaid on your phone screen, no matter what app or screen you're on, like this:
In the above example, the circle near the top right-hand corner with the red number 2 on it is the floating chat. The chat circle will contain a picture of your contact if you've associated a picture with them (in this case, Robocop), and the 2 is how many unread messages you have from that contact. Tap on the circle to expand it and read or reply to the message.
TextNow popup: Similar to the chat heads except it pops up a box overlay at the top of any given screen during an incoming message. You can reply to your contact directly from this box.
Lock screen quick reply: Very similar to the popup above, except it will also appear on your lock screen when your phone is locked.
