Masking Agent....Patent

[kqlnut]

Thinking on the difficulties regarding providers I was wondering if a masking agent similar to whats available for browsers was possible,

I had a tough time with the terminology to even get any results, call masking kept coming up, but what I found sure didn't surprise me

an IBM patent

I didn't comb through it but on the surface....

What difficulties are you referring to? That some providers don't accept the Pinephone because it's not on their whitelist? In that case you would want to look for IMEI spoofing. That's something that would happen in the modem, but there is no known way to do that on the Pinephone's modem (yet; as far as I know). Also it might not be legal everywhere.
Or do you mean masking your phone number when making calls? For this you could look into proxy numbers.
The link you provided has nothing to do with either of that.
