how about using the latest FW? [https://source.sierrawireless.com/resources/airprime/software/hl8548-hl8548-g-hl8549-and-hl8549-g-firmware/#sthash.u52Cr7Mk.dpbs](https://source.sierrawireless.com/resources/airprime/software/hl8548-hl8548-g-hl8549-and-hl8549-g-firmware/#sthash.u52Cr7Mk.dpbs) After that you can also try if AT+NVRST=2 helps: > [@HL8548 CGATT=1 results in Unspecified GPRS error until CGATT=1 is called multiple times in a row](https://forum.sierrawireless.com/t/hl8548-cgatt-1-results-in-unspecified-gprs-error-until-cgatt-1-is-called-multiple-times-in-a-row/16029/11): > > Hi robvice, I cannot help if a hardware issue. Regarding “AT+COPS=? +CME ERROR: no network service” issue, please try to restore all the NV default value including customer settings by AT+NVRST=2(a reset will happen automatically) to see if it can help. Or try to upgrade FW again. ---
