Bob, you can get prepaid unlimited talk and text with 500 mb of data for $45 per month, and with auto pay you get i gig of data from Verizon. More data is $20 for 3 gigs to be used up to 90 days.
If your phone is out of contract, or you own your phone you can get this plan.
I had an iPhone 5 for over 2 years using straight talk. I had no problems with talk and text but with data was extremely slow compared to my wife's 5 on the Verizon plan and she had better talk performance when out in the country. Now I understand that straightalk does have 4g lte if your phone has it. The FCC recently fined st for advertising unlimited data and throttling after 3 gigs. In fact if you had st and was throttled, or data turned off, you can file for a refund in a class action. Most of the time, I would get about 1 meg down and .25 mg upload while wife was getting 30 Meg's down and 20 Meg's up at the same place.
My son gave me a iphone 6 plus for Christmas and put me on his plan. We own 2 iphone 6 and 2 iPhone 5. If you own your own phone, Verizon give a $25 per phone discount. My phone is $15 per month plus data with unlimited talk and text. At the breakfast restaurant, I get 30 plus Meg's down and 20 plus megs up, at the same place, st never got over 1.5 megs. I will not go back to st.
