HWIC-3G-GSM with Vodafone SIM UK

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.

If I put a brand new Vodafone sim into a brand new unused Cisco HWIC-3G-GSM card I can establish a connection to the Vodafone 3G network, I obtain an IP address and can access the internet.
If I put a brand new Vodafone sim into a Cisco HWIC-3G-GSM that has previously been used with another providers sim card, in this case T-Mobile or Orange, then I cannot establish a connection to the Vodafone 3G network and do not obtain an IP address.
If I take the same Cisco HWIC-3G-GSM card that failed with a Vodafone sim, it works fine with T-mobile and Orange.
The Vodafone sims that do not work in the Cisco HWIC-3G-GSM do work in a Nokia N95 phone handset.
From what i can see its as if the IOS cannot communicate with the modem in the HWIC-3G-GSM card if its been used previously.
Im using a Cisco 1841 running c1841-advsecurityk9-mz.124-15.T3.bin, here's the relevant parts of the config I am using:

Although profile 1 has the correct APN and chap details i actually wrote this infomation when a T-Moblie sim was in the HWIC-3G-GSM. If I try to write a profile with the Vodafone sim or infact delete the profile the modem does not respond as shown below:
3GRouter#cellular 0/0/0 gsm profile delete 1
Profile 1 will be deleted
Are you sure? [confirm]
Profile 1 deleted from modem

As mentioned previously i can take the exact same Cisco 1841, same HWIC-3G-GSM replacing the Vodafone sim with a T-Mobile or Orange sim, use same IOS config and the only thing i change is the APN details in the profile to the relevant providers details and everything works fine. I can take the Vodafone sim that does not work in my used HWIC-3G-GSM card and put it into a brand new unused HWIC-3G-GSM card and it will work fine! I have spoken to Vodafone 3rd line and they have confirmed they have no block, bar, or resriction on IMEI on the sims and and the Vodafone sims I have all work in a Nokia N95 handset.
Does anybody know what may be casuing the modem in the HWIC-3G-GSM not to respond?

Re: HWIC-3G-GSM with Vodafone SIM UK

Dear All,

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.

Re: HWIC-3G-GSM with Vodafone SIM UK

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.
