When choosing a number the phone says Calling but it never connects. This was a recurring issue abroad but now it seems to be the case also in the UK. Would like help on this for both calling within the UK and when travelling</P> Tue, 04 Nov 2025 16:11:37 GMT https://community.o2.co.uk/t5/Tech-Support/Cannot-make-phone-calls/m-p/1817538#M58350 Dziobak 2025-11-04T16:11:37Z https://community.o2.co.uk/t5/Tech-Support/Cannot-make-phone-calls/m-p/1817539#M58351 <P><a href="https://community.o2.co.uk/t5/user/viewprofilepage/user-id/5867878">@Dziobak</a>&nbsp;</P><P class="">This is a customer to customer community, not O2, so we cannot access your account, sorry.</P><P class="">You need to contact O2.</P><P class=""><SPAN class="">Message them on Social Media.
