What do the abbreviations CME and CMS mean in GSM?
I know that the CME errors are equipment related errors and CMS errors are network related, but I’m not sure if this is true as I don’t know what those abbreviations really mean and I coul… Continue reading Explanation of CME and CMS meaning in GSM [closed]
Due to there are large encrypted files we are dealing with, we can’t afford to keep entire file in memory during a decryption process.
I’ve implemented the algorithm of chunked decryption of AES GSM encrypted file.

There are a lot of eSIM providers out there — but not every device supports an eSIM. Just about every device does support a physical SIM.
How can I program the information from an eSIM into a (blank) physical SIM?

I have seen around some 5G cellular kits that can be connected to SBC (Single Board Computers) in order to make a WIFI hotspot. From the one side, they provide 5G cellular connection and from the other side, they support WIFI connection.
D… Continue reading Do 5G cellular kits than are connected to SBC, support encryption when the signal goes via them to the wifi?
Over the past decade or so, smartphones have exploded in popularity and seamlessly integrated themselves into nearly every aspect of most people’s lives. Although that comes with a few downsides …read more Continue reading Open-Source Cell Phone Based on ESP32
I’m trying to understand how the eSIM is protected against cloning. Here is the diagram from GSMA standard:
Now the ICT operator has its own security domain in which all the GSM related keys probably lie. My intention is not to extract t… Continue reading eSIM/eUICC relay attacks
My question is Will enabling 4 only mode in a smartphone, prevent hackers from downgrading your connection to 3g/2g through fake towers.
Will using a Wpa3 router with VPN tethering function to share a 3g modem network protect someone from the vulnerabilities in a 3g network?
I know there are 4g and 5g, I just want to know how much is possible to build securely on an insecur… Continue reading Assuming 3g network is vulnerable, will it be also vulnerable if I tether it using a VPN router? [closed]
Is a remote control using a fake tower then downgrade 4g to 3g with the help radio commands possible ?
How such an attack is managed on a smartphone for example ?
