On the Issue of Sharp 90 10 Sending SMS

This is the difference between 18 10 9020 and 9 1 series or 90 10/series. The previous high-end series are all imported with GBK characters, which are easy to identify, and any pictures and texts can be input with complex characters. So you can only buy the highest-end Sharp. The gap between low-end and mid-range models is not generally small.
