  • Nice Phone
Nice cute little phone. It serves my purpose. It has exceeded my expectations. Compatible with cricket. No complains

  • Nice phone but it wouldn't take a charge.
When I got this phone it appeared to be new and in a new package but when I opened it up I noticed that it had a prepaid AT&T sim in the slot. So I took that sim out and put my Tello sim in and got it activated and set it up. It was about 50% charged when I got it and it seemed to work fine so I was very satisfied. But when I tried to charge it up completely it wouldn't take a charge. I went on Google and tried to find a solution but nothing worked. I finally got so frustrated about it that I took my new sim card out and threw the phone in the trash. Other than the charging problem it was a nice phone. ... show more

  • Slow phone
The phone does its job at a cheap cost. It is usable. It is very frustrating though because it is so slow. Maybe it can be improved with a memory stick. Using this phone is like going back to dial up internet. I recommend spending a little more to get something a little faster so you are not waiting a minute just for an app to open. I do not think this is a bad seller. I think this is a case of you get what you pay for. ... show more

  • DO NOT BUY THIS. IT DOESN'T WORK
This phone looked OK, but it must have been a return because the "SimBros simkey" was not in the box. The phone is older, and has a removal battery that I liked. After I put in the sim card, battery and back plate and plugged the charger in...nothing.. The charging light indicator did not come on, but I let it charge for 1 full hour in hopes the light was just not working. After the hour I tried to turn on the phone and nothing. This is a total waist of time. DO NOT BUY THIS UNLESS YOU LIKE DISAPPOINTMENT. ... show more
