Back in 2011, those purchasing a cellular enabled tablet did so as a result of what was available at the time they made the purchase. CCS Research noted that only half of those who purchased a tablet with a cellular radio activated their tablet with a cellular carrier. The report says that three factors will be key in determining how many cellular enabled tablets are sold in the future: The pricing of cellular plans from carriers, the availability of public Wi-Fi networks and the difference in pricing between Wi-Fi only and Cellular enabled tablets.
CCS Research's numbers are much more positive for cellular enabled tablets than some other research firms. ABI Research found that just one in three tablets sold world-wide in 2011 had a built in cellular modem while 27% of the 65 million tablets shipped in 2011 had support for a 3G/4G network. That works out to 17.6 million tablets.
