MC55i-W problems sending SMS PDU with long phone number? | Thales IoT Developer Community

July 8, 2019 - 8:28am, 2166 views

Hi,

we are using the Cinterion MC55i-W to send SMS. This seems not to work when there is a 15 digit (without country code) destination pnone number. Other numbers are working fine. Also the SMS PDU we create seems to be OK. Nevertheless the modem reports an error after the PDU is sent to it. Is there any experience that specific nubers are not working with this module?
