Sim-card deactivated accidentally - How to activate back?

[Olegnsk]

My kid got a new phone today and she was playing with settings (iPhone) and she removed the previous phone from the devices list and found that she deactivated the sim-card and it is not working now. How can the sim-card be activated back? 🙂 Thanks

OMG, @NDesai. God bless you! Thank you! I had no idea that removing and install back the sim card will help it to become working again. THANK YOU!

@Olegnsk It's not possible to deactivate the sim card from Phone settings. She might've disabled some network settings? If you have another phone, try the sim in that phone to see if it's working. Try reinserting the sim and go to cellular settings. Do you see any sign of Public Mobile network being recognized?
