I have purchased Nokia 308. But I am having problem due to small fonts of contact Nos. and there is no option to increase the fonts size. Please help me to download any application to increase the fonts size and oblige.
AFAIK upon this Series 40 device You can only change font size for messages in your device. To do so, select Menu > Messaging > More > scroll down to Message settings > General settings > Font size > Large Font
As only have Asha 302 available your user interface may be slightly different.
