I cant create an apple ID

Hello,

I’ve been trying to set up an iPad for my niece as a present but everytime i reach the sms verification code part to creat an apple ID it says error and when i try to put in the code again it says, “Please enter the characters you see or hear to continue”.

I have tried with two different iPhones, other than said iPad, to create the apple id but its the same every time. What can i do?
