Worked fairly well with my Samsung Galaxy S7 but it hasn't worked at all with the new Galaxy S20. I refuse to pay for the pro version of something that AT&T should be providing free for customers. We pay enough for service as it is. 2/23/2022 UPDATED Works to a point. BUT...it continues to baffle me why, when I pay over $170 a month for cell service, AT&T still wants an additional $3.95 per month, per line for this service when they say that my service is the premium, unlimited, very best plan.
