Well, if they take some extreme measures they probably could deny it,
based on EMEI numbers. But no, it probably will work, although some
networks callcenter support might have problems and insist to walk you
through a specific phone model menu to do something ;(

SIM stands for Subscriber Identity Module btw :)

Basically phones come in different variants:
-) unlocked, you can put any SIM into it.
-) locked to SIMs specific operator.
-) locked to a specific SIM.

The last two are usually refered to as a SIMLOCK or simlocked phone,
and one usually gets one these in subsidized contracts. OTOH this is
strictly operator/country specific. There is one additional thing,
branded phones.

-) branded => that's orthogonal to the above, it means that the
firmware of the phone was altered to do things for a given operator.
Usually this involves logos, binding certain hotkeys to a fixed WAP
dialin. Or some US operators have been known to kill features that
would allow transfering images out of the phone with something else
than their data plan :(

It's orthogonal, because there are branded phones that are not
simlocked, and one can put a different SIM into it and use it.

As examples:
In Austria, most phones bought at a shop operated by a network are
simlocked to the network of the operator. (Speciality phones sometimes
are not, because they are sold in to small numbers)

In Germany, they like to brand the phones, but they usually come
without a simlock.

But it does. That's why you have a "group reply" function in your
mailer. Some advanced mailers might even have a special "list reply"
function *g*

OTOH, adding a Reply-To to the messages pointing to the list makes
replying just to the poster for offtopic messages hard.

Nope, most technical mailing lists work this way. Only mailing lists
targeted to endusers that might have troubles operating their MUAs are
setup to include a Reply-To usually.
