For a number of years now we have been using a version of AT&T's Wireless Home Phone (WHP)service. It enables us to take our home phone with us when we travelled and kept our same number. The deal was good, $20 a month for unlimited talk. D/W preferred to use the Panasonic handset over our IPhone when making calls from our stick house or on the road or in our winter place.
Well they did away with the service but being grandfathered we are okay for a while, until 3G goes away and our Microcell is trashed (in our stick house we get only one bar on the iPhone but WIFI calling works good). The WHP does recognize the Microcell so we get five bars.
Question is, could I remove the sim from the new WHP device they shipped me and put it into an older iPhone we no longer use. The older iPhone has bluetooth and the Panasonic is set to accept bluetooth so I could pair them. Then I could put the older iPhone on WIFI calling and not miss the Microcell.
