I have an issue using Vodafone 3G enabled SIM cards with Cisco HWIC-3G-GSM in a Cisco 1841, i now have 6 HWIC-3G-GSM card that I cannot use at present due to this issue.
I am experiencing a similar problem. With an MTC sim Card Network services are up and running, with a LEO sim Card, Current service is stated invalid. The cards experiencing the problem is a HWIC-3G-GSM=-GR3 and both are doing exactly the same. Brand new SIM card have been tested with the same result.
With the LEO Sim Card, any attempts to configure the gsm profile results in an error Modem did not respond.
Is there perhaps a network lock on the device that I am not aware off? Take note that I am working for Leo directly with the Packet Core systems responsible for GPRS, GSM, 3G, HSDPA, and HSPA.
Attached is outputs of various differences in show cellular 0/0/0 all, with Leo Sim V01, without Sim, with MTC Sim and with a new Leo Sim card. V02 is the output with the very same sim card as in V01 but successful latch on network on a HWIC-3G-GSM= card with a sticker indicating HWIC-3G-GSM V02. The suspected locked cards shows HWIC-3G-GSM V01 on a similar sticker.
Between the 2 types, V01 and V02, there is definitely minor observable chipset differences. Their firmware is the same according to the output from a Cisco 2811.
I still haven't got to the bottom of this problem but I can confirm that all 6 HWIC-3G-GSM cards I have are V01. I do not have any V02 cards to test with.
