It is not always possible to determine where (or from who's phone) a text message originated from because the originating number can be faked. But let me do some checking... it may be possible to at least determine the carrier.
So 236 is British Columbia...
So looking around it seems like there are a lot of complaints about scams originating from the 236 area code. Can you tell me more about what this is about?
Don't respond to it, they may be using an automated system to collect phone numbers and build advertising lists. Just delete it
