Is the TCL A2 A507DL a good phone?

It's an ultra budget phone with marginal quality and a large screen with very low resolution and poor pixel density.  

There are much  better phones for just a bit more money. 

Yes, my cousin have been using that phone for years. It's a quality phone that is cheap, affordable, and have the same features as a 500 dollar Iphone.

You should opt for a prepaid Samsung from Walmart. They're good phones. But make sure you specify no refurbished or used phones. 

No it’s cheap and won’t last you very long.
