Issues with instagram verification code to my phone specifically


Hello - I cannot log in to my Instagram account because I am not receiving SMS test from Instagram to login to account - I just switched over to Verizon. I am receiving SMS messages from other people as well as iMessages. I have deleted and re-downloaded the app as well as restarted my phone and nothing has worked. I have also confirmed that there is no messaging block feature added to my mobile number that would restrict you from receiving notification alerts from Instagram. Please assist.
