I currently carry a dual-sim phone to have two numbers, private and work each. I am not entirely happy with this setup however:

  • Dual sim phones aren’t common and cost more when I have to upgrade.
  • I need call recording for business, but android phones aren’t very clear when it comes to call recording support. I had to try and return several new devices.
  • I would love to have additional temporary phone numbers for privacy (e.g. retails).

And here’s my situation:

  • Google Voice is not available in my country. Plus, it’s Google.
  • Prepaid SIM cards are cheap and easy to acquire where I live.
  • I have a bunch of old spare android phones.

I was thinking, could I leave the SIM cards for private and work at home, inserted to phones/devices that are managed by a call-forwarding server, which transparently forward the calls to a third device I am actually carrying?

Self hosted Google Voice is what I would love to have.

    Asterisk / FreeSWITCH. Not sure why you insist on having a SIM card, it’s possible with both of these using cellular modems, but it’s a lot easier to just get a DID from a VoIP provider.

      This is the route I’d go. I use FreePBX for all this, but my voip provider could do most of the work (voip.ms). There are decent softphone apps (Zoiper, Linphone, etc.) to initiate calls from and porting a number to the voip provider isn’t too difficult.

      I was thinking about preserving my phone numbers and all that. From what I’m reading, all it takes is a voip provider routing calls directly instead of my own equipment?

        Yes, you can also let the provider do all the work if you prefer.

    Google Voice is not available in my country. Plus, it’s Google.

    Also, Google Voice takes my top pick for the next round of Google product executions. It receives no updates: no RCS, no fake iMessage support (parsing the Liked "prev message" stuff), and it’s buggy as shit.

    I’d gladly even pay for GVoice if it meant it got a renovation and it was going to outlast Google’s attention span. Telephony is something I just don’t want to self-host because there’s no way telecom companies will make it easy.

      Actually VoIP is mindboggling easy (or I should say can be, it can indeed get incredibly complex if you want it to, the same software is used to host thousands extensions PBXs in call centers), and has been a thing in the self hosting community for decades…

      Not everyone here uses the actual dual slot. Some are single sim model variants advertised as dual sim, or one of the slotz have their imei on a blacklist.
