View Full Version : [ubuntu] e220 Stopped Working, CME ERROR: SIM failure

January 17th, 2011, 12:00 PM
Hi. I am using a Huawei E220 in Zambia. The modem has been great. However, it suddenly stopped working recently, displaying the following in the wvdial output during Init:
'+CME ERROR: SIM failure'.

It had been working before just fine. I swapped a known working sim card into the modem, and it didn't work. I swapped the supposedly bad sim card that wasn't working in the modem into a working modem - and it worked just fine. I believe I have isolated the issue to the modem itself. After perusing a number of posts, the only thing I have come up with is that the SIM is inserted incorrectly.

Any ideas?

Busted modem? Needs to be reprogrammed? Strange setting?
