In recent years my cell phones have been Samsung SGH-31x series. Unfortunately they do not recognize the year 2015.
Free practical advice if this has happened to you: Auto time will never work again so keep it charged. Too, also, when you enter the date enter the year as 2009 in 2015. Not a leap year and started on Thursday.
In recent years I have been on the T-Mobile cheap plan, $2.00 per day if I use it even once. My experience of one smart phone is that it calls home every day and triggers the two dollar charge.
If I go to an expensive plan can I tether it to my main computer and drop Crapcast?
