My family recently purchased the four phone, shared 15gb family plan. Two phones are Samsung Galaxy 9 and two are Moto G6. When I compare cell reception while driving, between the Samsung and Motorola phones, I get completely different results. The Moto G6 gets 1 to three bars of 3G reception, while the Samsung phone gets 3 to 5 bars of 4G LTE in the same vehicle, at the same time. The Samsung phone is the primary on the account. Is this just a basic difference between these phones, or is there some kind of tiered reception between the primary account phone and the shared phones?
