kpc21 1 | 763 3 Jul 2015 #5For mobile phones such a service is not needed, you always can see the number of who is calling, unless this is a "restricted" number (its owner doesn't want the number to be displayed on others' phones and activated a special service).In case of landlines, you can activate this if you have a telephone, which is modern enough. In case of some operators (e.g. Netia), you have to pay for this service extra, for some (e.g. Orange) it's free. But, there is no exactly such a service as you are writing about in Poland.The service I am writing about is called CLIP, for English Calling Line Identification Presentation (this abbreviation is used by Polish telephone service providers, especially the landline ones). The service of "restricting" a number is CLIR (Calling Line Identification Restriction).
