Do not port your cell number to TextNow. TextNow has a product where they can send you a SIM card (Sprint only) and then you can port over your cell phone number and you now have free talk and text. Data costs (lots) extra. But TextNow is very flakey. It kind of works but as a daily driver for voice you will hate it. And if you use a VPN you will find yourself shutting it off to even text! And because tech support is so bad porting your number back will not go smoothly! Trust me! I know!
