I am looking for the cheapest mobile phone plan for my parents who will visit in USA in near future.

lycamobile ultra mobile, mint mobile all are crap. Check out Red Pocket hands down the best. The people commenting Lyca, Ultra etc possibly have never come across Red Pocket. Lyca runs on T-Mobile’s crap network and so does Ultra. Only network in US that lets you choose the network is Red Pocket. I’ve used Lyca for 2 long years. It’s crappy.

Summary:

  1. H2O
  2. Lyca Mobile
  3. Mint Mobile
  4. https://hellomobile.com/
  5. Red Pocket
