Features & screenshots

SichboPhone takes your privacy serious and always authenticates over PayPal. Your PayPal account is your SichboPhone account. This way none of your personal details are ever stored on our servers.

Don't you miss the good old ICQ and MSN Messenger days when chat programs opened each person in their own fricken window? Yeah.. me too. So I did the thing.
The SichboPhone settings screen on PC.
I'm hoping you'll find the Settings super easy to get around in.
The SichboPhone history screen on PC.
All of your calls, texts and wholesale charges can be easily reviewed. Your texts are encrypted at rest on our servers and you can redact things at any time.

Also, calls to other SichboPhone users are free, since we don't need to involve the telco provider.
The SichboPhone number configuration on PC.
Custom answer rules can be set up for any of your numbers as well as on specific contacts. For example you can "block everybody" but "always accept" calls from somebody special.

Why did you make SichboPhone?

I got a 2nd hand Nokia off ebay ages ago and wanted to turn it into an actual functioning phone, but I was too cheap to pay some outrageous monthly fee to a greedy phone company. I'm always on WiFi anyway so I made this thing.

Even though SichboPhone was designed for touch/mobile, it works equally great on PCs and tablets, and soon the new ARM64 "always on" gear, which will be nice for an always-on phone system.

I hope you'll find it useful.
