My phone (S8) gets better reception than Susan's iPhone 7. With our Wilson booster (non-cradle) we have had to both be near the passive candy-bar antenna until it dawned on me that she could connect to my phone via my mobile hotspot. This feature is included on our rate plan and not only does it allow her to be elsewhere- even outside- she also gets a better data connection. I turn on my hotspot and she then turns on her wifi to connect to my phone.
