We just had regular hiking poles, but I broke them down, put them in one of those triangular postal service mailing tubes and checked the tube. Worked great from Denver to Madrid.
I was able to use tools like Facebook, FB Messenger, Skype for calls, email and FaceTime via free WiFi connections for my communications throughout our Camino from Sarria into Santiago. Did not get a SIM card.
