I do not want a new SIM card or number I just want to change the tariff on my existing SIM. How do I do this if I am taking advantage of an O2 offer in money supermarket or uSwitch?</SPAN></P> Mon, 23 Jun 2025 13:50:01 GMT https://community.o2.co.uk/t5/Pay-Monthly/SIM-upgrade/m-p/1799119#M289940 Hubert25000 2025-06-23T13:50:01Z https://community.o2.co.uk/t5/Pay-Monthly/SIM-upgrade/m-p/1799121#M289941 <P>It seems that O2 have stopped this way of upgrading</P><P>This may be temporary as this happened previously in March and early April this year</P><P>Or it could just be one system is failing and hopefully will be fixed in the next couple of days</P><P>You might want to check with O2</P><P><LI-PRODUCT title="Guide: How to find help &amp;amp; contact O2" id="Guide058"></LI-PRODUCT>&nbsp;</P> Mon, 23 Jun 2025 14:04:57 GMT https://community.o2.co.uk/t5/Pay-Monthly/SIM-upgrade/m-p/1799121#M289941 jonsie 2025-06-23T14:04:57Z
