Need help with connecting MC7355 to Sprint 4G LTE Network - SIM card?

IoT Modules MC/EM Series
6

Please refer this post WE826 with MC7354 did not work with Sprint - #8 by Oedenburger

Sprint normally uses “otasn” on PDN1 but is is only used by Sprint for over the air provisioning.
Data “n.ispsn” is on PDN3. FW upgrade should take care of that.
