I'm using Kannel 1.5 with the Huawei E220, everything is working fine, but after about 10 000 text messages sent and received (in about 24 hours) I get the message "Initialization of device fails" and the modem would need to be unplugged and plugged back in to work properly again. I am away from the server so this is great inconvenience for me. Here is the exact messages I get when this problem occurs

Please advise as if there is anything I can do to fix the issue. If not please recommend a modem which would be stable.
