I've just switched over from Vodafone to ID. I kept the same number and the switch was completed 2 days ago. However, I can receive and make calls with my new phone (Galaxy S20FE) BUT when someone texts me back it pops up on my old S8. So, I took out the SIM card. Guess what, texts still come through!!!!!! I have no idea why and how, it says emergency calls only so shouldn't work. How is it doing this???? Any ideas guys. Thanks
