New to Wifi

I know that if I connect my BB to my router I get unlimited internet, but how does the wifi calling work? My phone says UMA on it, and I have T-Mobile U.S. service, but I dont pay any extra for hotspot calling. Is that just automatic if it is connected to router? Thank you.

On a side note, I will be upgrading to 4.5 OS tonight, will I have a new updated browser? I have 4.2 now.

Also, if no new better browser, then other than Opera Mini, what is a good one?

You have to use the T-Mobile WiFi router.
The OEM Browser and Opera Mini are the only browsers right now. FireFox should have a mobile version soon.

You will still get charged unless you have the UMA calling which is an additional 10 bucks foe unlimited calling.

ok thats what i thought as far as the plan was concerned. that works for me. Thank you.

BTW, welcome to the CB family!
