Q: Int'l Frequencies

I have a spare v180 the status of which says frequencies are 900-850/1900

Q1: Does this mean that it will operate on 900 or 850 or 1900?

Q2: If an int'l company operates on 900/1800, does this mean that the v180
will roam/connect (on 900)?

TIA

Yes.

Some varieties of the V180 operate on 850-900-1800-1900 (e.g. the
unbranded and AT&T models).

Depends. If you are using a USA SIM and are roaming in Europe, you should
be able to connect to any carrier your USA company has an agreement with,
having 900 MHz towers.

If you are using a foreign SIM in its country of origin, it may or may not
work. For instance, in UK, there is no such thing as domestic roaming
between carriers. So if you are in an area where your UK carrier only has
1800 Mz towers, your phone would be a paper weight.

Mike;

Thanks for the reply, I will be using a US SIM with int'l roaming account.

Q: If an int'l carrier lists frequencies as 900/1800, does this mean that
their towers service both frequencies simultaneously, or different
frequencies in various locations?

As I understand it, usually the latter. Various patterns exist. Some carriers
are exclusively 900 or 1800 throughout their coverage areas. (The maps at
www.gsmworld.com can help with this gross distinction). Some use 900 for
most of their coverage, and 1800 for overflow/expansion.
