Normally many mobile devices should be able to access your website. However your website, which has not been optimized for mobile display, may looks pretty crappy on those handsets, like mobile phone, smart phone, tablet. A website designed to be viewed on laptop, PC, computers might not work well on some mobile devices. If you have a website, you should definitely test it on a mobile device, especially the most popular ones like iPhone, iPad, Samsung Galaxy phones, HTC phones, Nokia Windows phones, Microsoft tablet Windows RT, etc.
When you use a mobile device to access a website, like the iPhone for example, it is likely to take longer to load, the screen is much smaller compared to a desktop computer and navigation requires a lot of zooming and pinching. If you happen to open some web page with flash content, you will find they are not displaying at all on iPhone. A mobile device does not have the same horsepower that desktop computers have to handle high bandwidth sites as quickly as PCs. It does not have a wide screen to display very wide or long web pages. It does not support some of the popular scripts or files either.
