Can one make a Subject Access Request of a telephone Communications Provider?
<p>I have received a suspected scam telephone call.  Searching the internet for the number I found that &quot;phone block 247520 is operated by DIDWW Ireland Limited&quot;.  Searching this I came across the <a href="https://www.ofcom.org.uk/__data/assets/pdf_file/0024/214917/scam-nuisance-calls.pdf" rel="nofollow noreferrer">Ofcom response to a very similar incident</a> that makes no mention of the possibility of using the GDPR to require the Communications Provider to identify the source.</p>
<p>It seems to me that the Communications Provider would be a data processor, as they are routing the call to my number, with is personal information.  Would a subject access request set to the GDPR contact email on their <a href="https://www.didww.com/" rel="nofollow noreferrer">web site</a> be valid, in that they would be legally required to sent it to the relevant data controller?</p>

<p>I don't see this getting you anywhere, an SAR to the telecoms provider will put them in the position of having to give you the PII they have of yours, but I doubt they would be giving you anyone else's. So you might get the what you already know: that you received a call at the date and time. DDIW are just a SIP/VoIP provider, they aren't the ones that called you and they aren't going to be giving you the customer's identity who did.</p>
