Trouble when using both GET REQUEST and SMS

Hello, I am using sim7000 Arduino Expansion shield and i have a problem. When i use only GET REQUESTS (3 exactly)everything is okay but when i am trying to send and a message then ONE OF MY REQUEST can't send and i don't know why this happens. Does anyone knows the answer?

My crystal ball says you have an error in line 63 in your sketch.

On the other hand my crystal ball says that if you don't the solution just don't answer

If you fail to formulate your post according to Read this before posting a programming question even on your 20th post, you have to expect sarcastic answers.

no one will be able ‘to guess’ (not even angels) what’s wrong unless you post your sketch here
