There are a few ways to block and unblock a number from the TextNow service: Block Or Unblock Using The TextNow App. Tap on the conversation or call log from the number you're looking to block. Use the drop-down menu (tap the icon with the three dots in the top right-hand corner) and choose Block Number from that menu.
For example, to block incoming text messages from 416-999-2430, the message would read:  block 4169992430 . After the block was successful, the system will reply to let you know the number has been blocked. We do not currently have a way of blocking incoming texts on GSM devices.
