Taxes

So I marriedc and moved to Missouri. We put my att phones on his account so we weren't paying double. But we still kept our Oklahoma phone#. Cause one it was easier, 2 its way too expensive.

So here's my question. On our bill I pay Missouri taxes, much cheaper, and my daughter s line pays Oklahoma. And they charge for every little thing.. So why is that. We use the phones in Missouri. Mine has me there with OK # . why not hers? Its bad enough the phones cost a, house payment. And u have no choice but to get a good one or the features that come in the pricey plan don't work.. And most of us can't even work the stupid things.
