FaceTime and iMessage activation stuck after switching SIM cards

I switched a new sim on my phone for a calling purpose but then I again switched it to my old sim but after that my face time and iMessage activation kept spinning and it doesn’t activate. My phone is updated to the latest the network and wifi connection is also okay. Date and time is also ok. but I don’t know why is it still not activating.
