I bought a 5800 from this seller recently. The transaction was smooth, he said that the unit he sold was well taken care of. It looked fine. He said that the battery life was ok, that it would last upto 2 days. That was incorrect. I sent him a message about it to inform him. He asked me for a rating even after expressing my dissatisfaction with the phone's battery life, I did not post a rating because I had reason to give him a negative one. Understanding that some sellers don't tell you everything when you buy a seccond hand phone, I let it go. However, a different issue came up today. The unit kept on showing the "SIM CARD REGISTRATION FAILED" notice. Now I have no means to use my sim with this unit that apparently has been blocked by either globe or smart. Now this I can't let slide anymore. I am giving pabilipoako negative feedback for witholding this information that now doesn't allow me to use my phone.
