Why did you make SichboPhone?
I got a cheap 2nd hand Nokia Lumia off ebay and wanted to turn it into an actual functioning phone, but didn't want to pay some outrageous monthly fee to a greedy phone company or spend a bunch of money over it. I'm always on WiFi anyway so I made my own softphone that uses a wholesale telco provider and doesn't have any markup on its calling or SMS rates.
Even though SichboPhone was designed for touch/mobile, it works equally great on PCs and tablets.

SichboPhone as a Skype alternative
Unlike Skype, SichboPhone actually lets you send/receive SMS texts on your PC.
Designed to be a really simple softphone
My goal for SichboPhone was to build the simplest to use and best integrated softphone available for Windows 10 that provides a real working mobile phone number.
Using SichboPhone as a pre-paid mobile alternative
Avoid rate markups imposed by regular pre-paid mobile plans. Perfect if you just need something super cheap for casual calling/texting when you're near wifi.
