The e sim showed as activated yesterday &nbsp;when i completed the contract. Ive got a text today confirming my old phone number has been ported to O2, however I cannot make phone calls to most of the numbers in my contacts. I can call my wife who is also an o2 user but no others. Please help</P> Tue, 22 Oct 2024 13:06:03 GMT https://community.o2.co.uk/t5/Pay-Monthly/Cannot-call-all-numbers/m-p/1756797#M283939 Keith_marriott 2024-10-22T13:06:03Z https://community.o2.co.uk/t5/Pay-Monthly/Cannot-call-all-numbers/m-p/1756801#M283940 <P>It can take a couple of days for all of the systems that route calls to settle down after a number port&nbsp;<a href="https://community.o2.co.uk/t5/user/viewprofilepage/user-id/5695031">@Keith_marriott</a>&nbsp;</P> <P>Keep rebooting your phone as well, but if you are still struggling on Thursday then get in touch with o2 - all numbers are in the guide below&nbsp;</P> <P><LI-PRODUCT title="Guide: How to find help &amp;amp; contact O2" id="Guide058"></LI-PRODUCT>&nbsp;</P> Tue, 22 Oct 2024 13:14:22 GMT https://community.o2.co.uk/t5/Pay-Monthly/Cannot-call-all-numbers/m-p/1756801#M283940 gmarkj 2024-10-22T13:14:22Z
