Virgin Media O2 patches hole that let callers snoop on your coordinates UK telco Virgin Media O2 has fixed an issue with its 4G Calling feature that allowed users' general location to be discerned by those who called them. The confirmation was issued in response to a mobile networking specialist publishing research into the mobile network operator's (MNO) implementation of Voice over LTE (VoLTE), …

The house style at The Register being American English, it would be "Meter"

"...locate users within 100 meters"
"He said theoretically, in some cases, this could be accurate to within 100 square meters."
These two thing are *very* different. Within 100m is accurate to a specific street or block of houses, but 100 square meters is a 10mx10m square! that's enough to pinpoint a specific building, and in some cases even a specific room.
In the guy's blog, he uses "100m2" unambiguously, and doesn't appear to say "within 100 meters" anywhere, so I think that's a case of journalistic inexactitude, unless that line was taken from a different article or something;
"Each site in these areas can often cover areas as small as 100m2. In a city, this becomes an extremely accurate measure of location."
So yeah, 10mx10m.
Why the stupid and pointless geography lesson? It's irrelevant to the story which country Copenhagen is in. We all know where Copenhagen is too. And was that the Denmark in Europe or was it the one in Asia?
BTW, what sort of meters were involved, water? gas?, electricity? sound? air pressure? Note to the editor: the SI unit of length is the metre. It isn't spelled "meter". FFS fix this.

Mobile location identification for emergency services uses a different system, thus filtering out SIP headers that leak metadata wouldn't impact such.
You cannot "block cell location" - the way mobile networks works means that mobile companies can and do record the location data of every customer by IMEI (device id) and IMSI (account id) and sell that.
Mobile devices also contain a GPS chipset, which cannot be turned off (only asked to go into a low-power mode), that determines the precise location - which is provided to whatever party that pays on the mobile side (even rough 100mx100m or 1kmx1km location data good enough for most nefarious purposes, but 4mx4m is nicer).
In Android, reportedly turning "location data off" still results in the current location still being sent to google occasionally.
"You cannot "block cell location" - the way mobile networks works means that mobile companies can and do record the location data of every customer by IMEI (device id) and IMSI (account id) and sell that."
How do you know that the mobile operators are selling location data? and how do you know exactly what form of location data they are selling? Are you referring to mobile operators in a particular country/countries (i.e. the USA where data protection laws are weak/practically non-existant) or making a blanket statement referring to mobile operators all over the world?
For mobile operators to sell (i.e. "share") IMEI/IMSI location data in the UK or EU without a valid lawful basis would likely be a breach of UK GDPR/(EU) GDPR as IMEI/IMSI are likely to be considered "personal data".
"IMSI (account id)"
The IMSI is the "id" of the SIM card, it's not an account id, e.g. a business account with a mobile operator likely would have multiple phones/SIMs and therefore multiple IMSIs associated with that account id.
"Mobile devices also contain a GPS chipset, which cannot be turned off (only asked to go into a low-power mode)"
Not necessary true, many/most mobile devices contain a GPS chipset (and GPS antenna), however there are the likes of non-Smartphones that come without GPS functionality and for those whilst some may have a GPS chipset that just isn't used (or no GPS antenna) there are likely to be others that have no GPS chipset (and/or GPS antenna) at all.
You seem to like making absolute/definitive statements where the reality is more finegrained than that.
