Free phone calls for Africa & the poorest of the poor

 According to  this article  your average African spends 8.8% of his income for 1GB of data. This is how to use  whatsapp without a sim card  and piggy back on anothers wifi for your phone calls for free.  This is more info I'm looking into for free SMS'es etc but the whatsapp route is away easier and likes being free so why mess with legal wrangling to get free phone calls. Whatsapp has 2 billion users worldwide as of Mar 2022, a quarter of the worlds population. How android open source uses the modem, the layer is callled RIL radio interface layer. The standard RIL uses the exact same AT modem commands I programmed at option when writing a 3d usb modem driver on a qualcomm chipset. https://android.googlesource.com/platform/hardware/ril/+/donut-release/reference-ril/reference-ril.c I am interested in sharing a phone connection via asterisk PABX software running on a raspberry pi with modem or ideally a plain mobile phone. so africans can make cheap calls o...

I'm calling sendmail superheroes, I'd like collaborators on this project

  I'm making plastic pony express email for Africans without an Internet connection i need to transfer thunderbird mailboxes via WiFi to yahoo. Will you help, I'm using GPS protocol and my carpool website for post box like management of data stored on phones and solid state disks airline hostesses will put their phone online in 5g connected countries with email from the back of beyond as well as free African WiFi hotspots. It is a small job and will be your legacy if you go for more glory. Also Google searches via email will be done sucking up first  page of results Wikipedia and one in direction level down from the Google search for pdfs and send it back as a cached result which others can use elastic search on the phone or raspberrypi.org.  I looked at  Sendmail book by O'Reilly available online, 1200 hard to read pages !!!, the code for sendmail is shorter.The users of this technology won't be sendmail guru's it's an unrealistic expectation. I'm looking ...

Muel mail and internet

I am making muel email and internet using gps protocol for the poor in Africa, delivery is done by carrying mail folders by phone or solid state disk from places without internet to a site with free wifi internet connection, the entire worthwhile internet can be delivered  by in a carry on bag full of solid state disks on a cheap commercial flight, a carrier pigeon can deliver 1 terabyte of email. High latency high throughput. Google add support for google searches via email sending back 3 web pages of results and files or i will have to kludge it.  If you think starlink can't be beaten maybe it can, if abaquerre warp drive  gets developed we can go back in time the worlds experiences can be delivered to people in the past via RNA which stores memories or using nuralink or simply by projecting images onto a wall with a projector from the solid state disks this is possibly how psychadellics work.

Getting normal wifi drones to fly around the earth controllable from 10000 miles away

This is illegal but probably possible from  https://www.zerotier.com Put a phone with zerotier piggybacking on a wifi drone. Use the phones camera to see where you are going with webrtc or FYD-FPV drone app. WIFI drones protocol and ip addresses are hackable with wireshark in promscious mode. The only bit I haven't figured out how to do is send the wifi packets over and back from the drone through the zerotier virtual device WIFI channels may be involved but getting the zerotier device using the same subnet might help.

Getting primitive phones to do modern things on the internet

Firstly I thought of an sms to email bridge  already done . Email to sms likewise  https://www.clicksend.com/en/sms/email-to-sms/ Google search by voice using tricks with "ok google" and a smartphone which auto answers calls I don't think its done, would it be usable using  DTMF  may help, I suspect google would have great difficulty with the voice quality.

Low tech email sms message in a bottle comms for all

On hindsight these ideas are primative and should have been done 50 years ago compared to modern telecoms but if there is nothing better there may still be room for these ideas.  As I said in previous posts a single raspberry pi can host 1000 email accounts provided the ulimit command is used to limit each accounts resources so people will prune their email and a 128gb flash drive is used costing 20 euro on amazon or even less on alibaba.com provided you pay import taxes later.  10 short emails and sms messages can be sent to a single sms email relay server in a single udp packet Leave comments if you have expertise and wish to cooperate on this endeavour. This contains gps coordinates of origin, timestamp, sms and email messages, md5sum , certs of authentication. A vic 20 could do a forth interpreter in 3k, 64k udp packet is plenty. SDRs software defined radio are useful for transmitting data in homebrew ways other than wifi or the telcoms network. See  gunradio  fo...
