Summary: I really like the phone. I was surprised to see it was an AT&T GO phone, but it was unlocked and worked with my T-mobile sim card. Only problem was the battery. It was 70% charged upon arrival and I charged it to 100% before using it but the charge did not last for very long and I had to order a new battery online (only a few more dollars). When plugged into the charger it runs just fine and also as long as the battery is working.
