Sony ericson WT18i is not a good phone first of all the display of phone is too small only 3.2 inches it is difficult to type anything with the small display and it has an internal memory of 150mb only which is the worst thing about this phone you can’t do anything with internal mb because the apps you download is installed in the internal memory everytime a message popu up on the phone’s screen insufficient storage delete some apps its like a headache except the sound quality nothing is good in this phone. Battary backup is very bad because this devices comes with an 1200mah capacity battary.overall is not a good phone.
