Horrible DO NOT BUY
Color: Blue
I wish I could put zero stars on this for the simple fact that this phone is meant for toddlers maybe 10-year-olds definitely not meant for adults. It is a throw phone. Basically it is so late. It is made very poorly it glitches it doesn’t load properly it doesn’t like to stay charged for more than two hours. It’s a horrible phone. Do not buy it. It is a waste of money.

No service, not compatible with tracphone sim as mentioned.
It is not compatible with a trac phone sim card as stated, false advertisement. You will not have active service because it is 2&3G only.

Insanely slow interface
Color: Blue
Insanely slow interface - tap on an app, nothing happens, tap on it again - wait, wait - finally app loads. Horrible. I was unable to get it to work with Speedtalk either - despite punching in all the network details (painful exercise) - steer well clear and throw some more money at a better phone
