Mobile phones connect to wireless networks to provide voice calls, texting, and other services. PDAs were early handheld devices that combined computing and networking features using a stylus, while smartphones integrate more advanced mobile phone capabilities with computing features in a single device. Smartphones allow users to store information, email, install apps, and make calls on one device, with features more focused on mobile communication than PDAs. There is no set definition, but smartphones generally have more capabilities than basic cell phones.
