Using an external 3G+key on a VPCS12V9E with a built-in 3G+key

[mdekeyser]

Sony VPCS12V9E has a 3G+key built-in. Is it possible to also use an external 3G+key or do I need to change the internal one?

If it is possible to use both (with different mobile operators), is there any specific guidelines to follow so that there is no confusion between both 3G+keys.

Thanks

It should be OK - after all it is just another network adapter on the system.

As long as you are using a different connection manager they should not clash but even if there is a problem, you can always temporarily disable the one you are not using in Network Connections.
