Cell Towers vs WiFi
What data is being shared from cell towers vs WiFi, and what your options to reduce that are
Intro
In this post, I’m going to teach you what data is being shared from cell towers vs WiFi, and what your options to reduce that are. The end has 3 example setups for the average person, somewhat savvy, and tinfoil hat.
Cell Towers
When you connect to cellphone towers:
IMEI
You’re using the modem which has an IMEI identification number. Using a DeGoogled phone and a VPN does NOT change this from revealing info about the hardware TO the TOWER, such as where it was bought. And who bought it.
Crypto Phone
There’s a couple ways to deal with this. One way is to buy it in cryptocurrency, from a company like mine. This is the easiest method for most people.
Hotspots
A second way is to use external hotspots for service, and buy those locally in cash. (or crypto like Calyx/T-mobile depending on your country.) Some prefer this because then they can put it in a faraday bag to hide their location at home. And only take it out of the faraday bag outside their house.
Change IMEI
A third way is to change the IMEI. This method is controversial, as some say it’s stealth. Others say you’re drawing attention to yourself by giving them bullshit or previous numbers.
LunarDAO
Some devices are easier to change then others. And some countries have made it illegal to change the IMEI. Of course, I can not recommend anything illegal. But if it is legal in your country, then generally older things such as Nokias are the easiest. LunarDAO has a guide on this:

Blue Merle
A combination of the 2nd and 3rd way can be done by using something like Blue Merle. This is software for GLiNET travel routers that changes the IMEI of the router. Then you could in theory swap different SIM cards. However, this has a high risk of potential error, for new users:

WiFi
When you connect to WiFi:
MAC address
You’re NOT using the IMEI. Instead, you’re getting a MAC address assigned to you by the router. This is a local area network. Android randomly generates MAC addresses for each connection, and you can actually see these in the settings of the WiFi connection.
Router hacks
In general, Android security is pretty good for WiFi. However, the CIA loves to hack routers. From the Wikileaks documents, we know they prefer to tunnel traffic from home routers directly to the CIA to see the traffic.
VPN -> DNS
There’s two main ways to avoid this. First, you could always use a VPN, which then bypasses the router’s DNS. (Routing Domain Names)
Firewall
Second, you could always be behind a firewall or travel router. The router’s WAN port is the one communicating with a modem (public internet). While the router’s LAN or (local area network) is the one giving you a MAC address.
Example Setups
What are some example setups?
Average Person:
Phone (bought with Crypto)
\/
SIM (bought with cash)
\/
VPN
\/
JMP Chat (VoIP)
(using public xmpp servers)
\/
Cell numbers
Savvy dude:
Phone (bought with Crypto)
\/
Silent Link (Crypto eSIM)
\/
VPN
\/
VPS you control
self-host xmpp
\/
JMP Chat (VoIP)
\/
Cell numbers
Tinfoil hat:
Phone (bought with Crypto)
Using Tor
\/
GLiNET router w/ SIM (Using VPN)
maybe faraday bags or IMEI changes
\/
VPS you control
self-host xmpp
\/
JMP Chat (VoIP)
\/
Cell numbers
Self-hosting the VPS just provides another layer of protection that you control between the hostile adversary and you.
So our team can help you get a Phone, or setup a VPS.

VPS Combo:
But even if you go with another option, I hope you digest my core message:
you’ve got way more control than you think
