The GSM Modem Connectivity option for the ELI 150 is soldered to the motherboard and is not field replaceable. If
there is a problem with the GSM Modem option the motherboard will require replacement.

for Europe (working in 900/1800 MHz bands) and F2 which is typically for North America (850/1900 MHz bands).
