Hey FLSMS community!
I am in Haiti trying to help some folks build an SMS-based anti-trafficking network. We are using a Falcom Samba GSM modem which has never steered me wrong, and two diff SIM cards (Digicel & Voila) and I keep getting an error message that says "SIM card invalid: GSM network registration failed)."
I noticed others had this issue but w diff modems. anyone have any ideas as to how i can fix this? We dont have any usb data cables and they are obviously hard to come by at the moment. Let me know if anyone has encountered a similar prob/know how to fix this, thanks!!
