Having strange issue sending Char array through SMS on mkr 1400

Official Hardware MKR Family MKR GSM 1400

I'm doing a project where I am sending GPS data through SMS. I'm having an issue sending a char array on SMS. I'm sending two char arrays; one is a prewritten statement, and one is the line of GPS information. The prewritten one is being sent normally; however, the GPS data is sent in multiple messages, and one char is added to the previous message. Even when I use strcat() to put them in one array, I get the exact same issue. Attached is my code and a screenshot of the messages. :pray:

i can't dive into your code, makin'me dizzy..

If you presss CMD+T (Mac) in the IDE the code is formatted.

Try to Serial.print() your output first. After it's correct, do the sms.print().
