this app has been a good number for in-between phones, it does reply slow as far as poping up to answer. Online text now numbers, are not recognized as actual phone numbers and at the most inconvenient times it redirects and reconnects calls. Wifi calling kicks in spatially, and it loads super slow, and receiving calls consistently is like hit and miss out of a 100% scale 10% of the calls actually go through and if it pops up the call atill gets dropped most of the time.
