It has been a lot of time since I tried and tried with different modules to work with my raspberry pi rig and, finally I have found your EC25-E module !!! it works flawlessly when it comes to configure my rig to connect to the net via cellular line (I have a vodafone sim card here in italy). Now I am in the process of playing with it further and deeper. I am planning to make a python interface that will connect with the module via usb/serial to make and answer to voice calls, send sms messages and so on… Sadly I haven’t received from the reseller any documentation in regards of the commands to send to the module. Where should I begin from ?
Thanks for your product, really.
