A month ago both my husband and I upgraded to an iPhone 6 (I had an iPhone5, he had a droid) and now we can only get 3G service at home. I also have a mifi on the same account and can get 4G on my computer and iPad but only 3G on the phones. I did get 4G on both of our old phones so don't know why the change. Our cconnection is much worse.
