After the C5-00 after a backup with the Nokia Suite could no longer start, replacement was needed. Because I do not want touch screen mobile phone, came only one with number pad in question. Due to the excellent material quality I stayed then hang the Nokia 515. A very good decision, as it turned out in the meantime. Processing really 1A and handling typical Nokia, all there where it should be and as we know it. The tip with the older version of Nokia Suite works perfectly. For me the perfect decision, also because the battery "forever" holds. 1 weeks despite much SMSs and phone calls no problem. I should mention perhaps that I have generally adjusted to the GSM network. This is perfectly adequate and saves energy.
