I had a 5 year old Samsung Gallaxy J7 and decided, rather than buy a new phone and new camera, to just buy a really good phone.
I bought an unlocked iPhone 13. I was able to transfer all my minutes/text/data from my old phone (had a LOT), but since I was close to the expiration date bought additional "minutes"
All the old data, text, minutes were removed once I bought new minutes since I went to a "smart phone" The minute card I purchased was for $20 with 1gb, unlimited minutes and texts and expires in a month.
I did find a switch on the iphone where I could tell it not to use my 1gb to assist my phone when in an area of low reception. BUT I LOVE THE PHONE!
My BF who has a Samsung Tracfone, told me he has to use the same plan.
