First of all, this is a cheap phone I bought as an emergency because my previous one fell and broke down, therefore I had to expect something bad coming ahead...and I wasn´t wrong. Signal is terrible, and there´s a party of errors everytime you try to send a message or make phone calls.Furthermore, everytime you input new info (SMS, calendar, contact´s, etc.) the system gets slower and slower. Calls fall randomly and the caller is sent directly to the message recorder when he attempts to call you back.Oh!...and a very important fact: the battery charge displays three bars when full. The first bar lasts a day or two, but the two remaining last no more than 5 hours. Very disappointing!!Please: don´t waste money on this crap. I used heavily for about three months, got another and this one went directlty to the trash can. I didn´t even considered giving it away to someone else.
