Description Laurent Bigonville 2015-03-07 11:28:40 UTC

Hello,

With the same modem, with one of my SIM card (Base) MM seems to work properly (even if the SIM card is not in service anymore I can use geoclue and get an approximate position). But with the SIM card from an other provider (Proximus), MM keeps releasing the modem. Note that sometimes, MM is also able to keep the modem up with the proximus SIM card, but this seems to be completely random.

The modem is, according to lsusb: ID 12d1:1001 Huawei Technologies Co., Ltd. E169/E620/E800 HSDPA Modem

Unfortunately, I don't think there is any clear thing we can do with this issue.

The Huawei modem is rebooting itself at some point when using the Proximus simcard, see the following logs:

I'd suggest to try to update the Huawei modem to the latest firmware available for that modem... :/
