This was my very first time of purchasing second-hand mobile phone since I've been using mobile phone for more than 22 years. I did a lots of online searching including Amazon, some of the reviews I read got me thinking it might not be possible to find any good phone due to some negative comments about some sellers on Amazon. I almost gave up and it was last minutes chance I came across your website. Oh man! It was a lucky chance indeed!. The Samsung S21 Ultra was truly pristine, the price paid and delivery was perfect. Smart Cellular, you make my day and will be back to get something for my family later.
