| | Re: How do I disable UMA?
But wifi is the only thing on, if you have turned mobile network off. The point is that UMA allows you to connect to the mobile network, if you will, for voice services, which includes text messages. I would assume that text messages work when on UMA, as you say it is happening.
My theory is that setting preferred network for calls to network only will prevent using UMA, which is what you want.
