Once I was over my fear of porting, I have used Cricket, Mint, Consumer Cellular, Visible, Ultra, Total and Red Pocket ATT & T Mobile. I will try US Mobile Warp speed within the next year.

i have not used Red Pocket Verizon. Try the service, you can port to another MVNO since you are not bound by a carrier finance plan. I was a loyal ATT customer but after a mistake on my son’s line, the loyalty quickly eroded.
