Hey Ronnie,
My nephew is an IT guy, and he turned us onto Mint Mobile. If you purchase it by the year, it's $15 a month. When we ordered the phones, we mentioned that ATT was the best cell tower coverage at my nephew's suggestion, and when they sent the SIM Chip, it was set up to ping ATT first. We all use Samsung phones and in the settings you can actually select which towers to ping first. When we traveled to California from Pennsylvania, I adjusted the phone in the settings for the best coverage while traveling across certain states, and it worked like a charm. The service is straightforward, no hidden fees, you get 4 GIG of data every month, but if you need more, you can double it for $10. This has been better by far than ANY Senior Plan offered even by the government for seniors. We had ATT and Verizon over the years, and the pricing and service were just awful. Being the skeptic I am, I tried the "One Month FREE" plan they offered at the time, beat all of the bugs out of my phone, (They even let us carry our "new" old phones over to the new plan, and keep our numbers) and when I was all warm and fuzzy about it, I purchased the 1 year plan, and have never looked back! Three years and running, still not a single issue. They even offer deals on new phones to go with the plans. NO CONTRACTS! If you don't like it, switch to something else at the end of the month. The way things are today, this is pretty much the FAIREST deal I have been able to find on cell phone packages.
I hope this helps you Ronnie, It sure made my life easier.
Earl
