Or sell them either.
An entry phone that's 5 years old is more responsive. The contact list lags a lot. The inbox needs an "Opening..." screen to load the text messages list which also lags when navigating up and down.\
Unless you buy it as an emergency phone and make the most of their "topup $x get the phone free" deal, I do not recommend it as a cheap, basic no bells-n-whistles phone which you may expect to be getting.
What happened to the cheap, reliable and solid basic phones?
