Yes you are!
Nice!
Please check out the #FITS content I've posted recently. I think you may fit right in with this sentiment.
Welcome!
This is the right sentiment
What was the last time you checked?
Also SIM cards are just a network identifier code that you carry on the device. I think its codes are transmitted to the towers for all these standards, and most commonly operators require you to use one to allow handover between commercial networks and countries. It has nothing much to do with protocol level requirements or modulation standards like CDMA.
DYK? Cellphones are basically networked radios.
Currently, there are two major standards in use around the world:
CDMA vs. GSM: What’s the Difference?
CDMA (Code Division Multiple Access) and GSM (Global System for Mobile Communications) are two popular mobile network technologies:
1. Technology Approach:
• CDMA assigns a unique code to each call, allowing multiple users on the same channel.
• GSM uses time slots (TDMA) and frequencies (FDMA) to separate users.
2. SIM Cards:
• CDMA phones traditionally didn’t use SIMs (device-specific).
• GSM phones always use SIM cards, making it easy to switch devices.
3. Global Reach:
• GSM is widely adopted worldwide, ideal for global roaming.
• CDMA is more regional, mainly used in the US and parts of Asia.
4. Data & Speed:
• CDMA often provided faster data rates in 3G.
• GSM became more versatile with 4G LTE, leveling the playing field.
In today’s world, 4G LTE and 5G have mostly unified these differences, with most carriers supporting SIM-based LTE systems.

Uhhh
Bunch of wrong info here i think
CDMA is a network access technology, a signal modulation technique used to enable resource sharing. As far as I know variants of CDMA have been used in 3G, 4G, 5G and this will continue in 6G. 2G constitutes GPRS and EDGE as data standards created by the GSM group, a standardising Committee of old. Now we have xGPP committees doing the same. GSM usually refers (in popular usage of the term) to a voice network. All use licensed bands. FDD and TDD (FDMA and TDMA) can be used orthogonal to CDMA and are also used to separate TX and RX from one radio to avoid self interference.

I recommend you go to his platform and look at Value Map and Spiral Chart.
You can explain a lot from there and they are very clearly structured.
We got there!
I mean, I'm trying to con everyone into nostr. Funny thing is after that they al staat doing the same to their friends! It's like a MLM scheme 🤣
I mean you don't have to use the service
I agree they should get through the hassle to accept bitcoin, not sure what reason not to...balready got the LNbits store? @benarc
Also maybe just a nostr login instead of an account to login?
Yesterday we were playing around with ideas at nostr:npub1s0veng2gvfwr62acrxhnqexq76sj6ldg3a5t935jy8e6w3shr5vsnwrmq5 , we needed something to preserve anonymity for blossom users that communicate with DVMs.
📢 Introducing Onion-routing for event publishing
This introduces insane privacy guarantees, someone can publish an event and not even the relay they are publishing from can now it's them, nor their IP address.
Technically this works very similar to Lightning, the sender constructs a route of pubkeys and can bounce around the message through pubkeys willing to route for them.
The sender can include small ecash tokens inside each onion layer to pay for the routing.
No hop in the route until the last one knows what they are routing, who its coming from and the sender very explicitly defines through which relays it should hop.
(for the sake of debugging, I built a traceroute-like view, so the sender can see the event being bounced around the different relays; in real conditions a sender wouldn't use that to preserve privacy)
Think of this like tor, just faster.

Amazing new piece of #freedomtech just dropped. Hold on to your 🥜
Ping nostr:npub1qny3tkh0acurzla8x3zy4nhrjz5zd8l9sy9jys09umwng00manysew95gx discuss this in the usual places please 🌱
Right, any chance you have the breakdown?
Would be interesting to see the split between ETFs and other whales gobbling up BTC since the launch
Only around 7% annual rate so far
Nobody will notice surely
Stacked my biweekly stack.
Like clockwork.
Study #bitcoin #FITS 🌱
Mine fiat, stack sats, stack time ⏳️
What part of that just corresponds with ETF accumulative inflow over this same period?
GM!
Stack more sats, you'll need them later. Time is of the essence.

Like admitting that the money wasn't real all along. #Bitcoin
