The Nokia C2-03 is one of the first Nokia dual SIM phones : Although it has been available for several years, it can with its relatively low price still score. The design is - for the now very low purchase price - still quite elegant. However, there are already some Android smartphones for 2 SIM cards in mobile testing , which are slightly more expensive and offer much more amenities.
The operation of the Nokia C2-03 is done under a sliding keyboard as well as via the touch screen. The is 2.6 "by today's standards, of course, very small, but in terms of color quality and luminosity very good.
As a classic mobile phone runs on the C2-03, the Nokia's own operating system Nokia S30 system. Unlike Android is not is an open operating system, ie there is hardly available apps and a few customization options.
Technically, the system for calling, texting, and manage contacts and appointments is but mature and practical.
For surfing the C2-03 is not ideal: it can only data about the slow GPRS / EDGE standard exchange, ie on the 2G network. Neither UMTS LTE yet available.
Little advantage after all: to live feeds from Facebook and Twitter can be accessed directly through a special integrated application.
The Nokia C2-03 uses so-called dual SIM standby, ie both cards have parallel channels, but can not use the same time to call, texting or surfing - as soon as a card uses a web service, the other is no longer logged into the network and any "has no power."
The change from SIM1 to SIM2 and back is quick keystroke.
