I was originally a Verizon user and grew tired of paying those outrages monthly bills. I was contemplating switch to one of the other big carriers and discovered Altice Mobile, They were offering at the time an unlimited talk, text and data plan for $40 a month with a lifetime guarantee that is remains $40. I was in the market and needed to obtain a new phone. I purchased an IPhone SE from them and have had the service for a little over 2 years. I you wish to call it a complaint, when I first had a minor problem, it was only possible to reach customer service through text. But that has since been improved, and you can contact them through voice communications. The service is great, I have never had a call dropped, User's recommendation: I highly recommend them.
