| | Re: How do I disable UMA?
You should not have been charged extra for texts or calls sent or received over UMA. Something else happened. Did you have the actual cellular radio turned off or just mobile data? If so, then the calls and texts could have still gone out over the mobile network.
The other possiblity is that Rogers could have a setting in their UMA/GAN system that knows you were connecting from outside of Canada based on your IP address and billed you at roaming rates. That would be a royal jerk move, but they didn't get Robbers as their nickname for nothing.
