and SMS

im working on a Project where i want to be connected with and to send a SMS sometimes. But when i try to send a SMS ,the Thinger.handle has an error while connecting after sending the SMS. Is it somehow possible to send an sms in my thinger code?
Im using an Arduino MKR 1400

Thank in advance!

After sending sms wait make a delay for 3 seconds

Thanks for the Answer, but it still doesent work. Even with 5 seconds. It just hangs up at “Using secure TLS/SSL connection: yes”
