I am using Celcom Home Wireless Broadband. One thing that I found quite unusual is, somehow the service is locked to just one place. I am sure that I didn't supply my home address to Celcom. But the modem only works at my home. I've run some test, it works in around 2-3km radius.

Now, I know that the FAQ states that the customer will not be able to bring this modem around as it’s locked to the registered address. What I don't understand is how the do that. As for now, I think the service is locked to a specific number of cells on a specific communication tower.

Anyone else try to move the modem around?

I concur this. I test the modem with other sim. I test the sim with other phone. I put an inverter in my car and drive around with the modem.
