Unfortunately, as others have said, Poser 11 needs to phone home every nine days or it will stop working.

This phone home requirement can't be permanently disabled, but you could try asking Support if they'll extend the time between phone-ins. I've heard they will do that, at least for some customers.

I'm not sure where you are, but here in the U.S., there are many places that offer free wi-fi. Libraries, coffee shops, grocery stores, doctor's offices, etc.

And it doesn't have to be always-on. It just needs to check in every nine days. So you wouldn't use a lot of data if you use your phone as a hot spot.
