Consumer Cellular is selling the Samsung Galaxy S9 for $670. That's $50 cheaper than the normal price from places like B&H Photo and directly from Samsung.
Their plans are pretty straight forward. I signed up for 1 line, 3GB data, unlimited talk & text and my monthly bill will be $40 per month. AARP members get an additional 5% discount. Also, all their plans are no-contract, unless you do a payment plan for your phone.Their service uses T-Mobile or AT&T cell towers, and you have 30 days to cancel everything for a full refund.
Oh also, their customer service is all US based and they are extremely helpful and according to my research, they have won a bunch of awards for best customer service in the past.
