⌛Time it takes to read this article: < 1 minutesLast updated: January 7, 2016 at 1:03 AM This may be the last Santa costume for this year. This photo was taken with the Sony Xperia Z3 SOL 26 below. Actually, starting next year, Y! I'm planning to throw away my mobile smartphone and change to a SIM from Mineo, an AU-based MVNO, so I also bought a Sony Xperia smartphone from Yahoo! Auctions for 30,000 yen. (Network usage restrictions are rated as ○.) Mineo also recently released SIMs that support VoLTE, so there was also the option of the latest Xperia models "Z4 and Z5." However, those models still have heat generation issues, so I decided to choose the Z3. The reason I chose Mineo is that it supports tethering, which is not supported by DoCoMo SIMs, and that the IP phone app "LaLa Call" can be used for free. As expected, since it's a flagship model, the performance is significantly different from the crappy smartphones I've been using. In particular, the camera and sound functions are excellent, and the overall performance is excellent. I think Sony is number one when it comes to smartphones!
