Comment 12 for bug 290177

For me it bails out on the first ATZ command if no PIN has been supplied. Could we just switch the order at which ATZ and AT+CPIN is sent to the device?

Using 'option' driver with the following device btw: 413c:8138 Dell Computer Corp. Wireless 5520 Voda I Mobile Broadband (3G HSDPA) Minicard EAP-SIM Port

Here are the relevant log parts with serial debugging:
