Most analysts are talking about what kind of boost in iPhone sales Apple Inc. (NASDAQ:AAPL) will see thanks to China Mobile. However, that’s not the only reason analysts following the company are cheering. Michael Walkley of Canaccord Genuity says surveys also point to very strong sales for the iPhone 5S, and that’s indication enough to boost his sales estimates for the iPhone.

Apple to sell 175 million iPhones

Walkley is estimating that Apple Inc. (NASDAQ:AAPL) will sell 175 million iPhones during the 2014 fiscal year. That’s compared to his previous estimate of 171 million iPhones. For the 2015 fiscal year, he is projecting that Apple will sell 193 million iPhones. Of course that’s so far away that the number could be changed numerous times before then.

The analyst cites numerous data points suggesting that the iPhone 5S is selling very well. A survey done by his own firm suggests the iPhone 5S is the world’s best-selling smartphone. It also indicates that the handset is the best-selling smartphone at each of the four biggest carriers in the U.S. Another survey—this one from Counterpoint Research—also showed the iPhone 5S as being the best-selling smartphone in the world during the month of October. Apple Inc. (NASDAQ:AAPL) has struggled to keep up with the immense demand for the handset, but finally, it seems to have done so.

Launching the iPhone on China Mobile

Walkley also points to the expected launch of the iPhone 5S on the China Mobile network. Most agree that it will be happening very soon. Preorders for iPhones on the China Mobile network were expected to begin this week, although we are running out of days. There were photos of the iPhone 5S posted on China Mobile’s website this week, however. Estimates for how many iPhones Apple Inc. (NASDAQ:AAPL) could sell on China Mobile’s network range from 15 million up to 25 million, depending on who you ask.
