Plane landed, turned my data back on and roaming. Within a few minutes I received a text from O2 stating I had access to my data etc etc just like normal. Since the 13th June my 5g signal has completely cut off and I have no access to any form of signal/data. I haven’t touched any settings it just stopped working. Does anyone know why this is?</P> Sat, 14 Jun 2025 06:25:48 GMT https://community.o2.co.uk/t5/Tech-Support/Roaming-issues/m-p/1797838#M57120 Joe29 2025-06-14T06:25:48Z https://community.o2.co.uk/t5/Tech-Support/Roaming-issues/m-p/1797839#M57121 <P>We are a community of customers here so can't advise on that.</P><P>Generally</P><P>Manually search for another network</P><P>Make sure 4G calling is on</P><P>Turn off 5g</P><P>Change your data APN to "mobile.o2.co.uk" if using an iPhone.</P><P>Check with O2 whether you have a roaming bar on your account.&nbsp;</P><P>Do this via social mediaIf you message O2 on Facebook ( <A href="https://o2uk.co/O2CFB" target="_blank" rel="noopener">https://o2uk.co/O2CFB</A>) ,&nbsp;</P><P>X Twitter ( <A href="https://o2uk.co/O2CTW" target="_blank" rel="noopener">https://o2uk.co/O2CTW</A>) or Instagram ( <A href="https://o2uk.co/O2CIG" target="_blank" rel="noopener">https://o2uk.co/O2CIG</A>) , they should be able to help</P> Sat, 14 Jun 2025 07:08:17 GMT https://community.o2.co.uk/t5/Tech-Support/Roaming-issues/m-p/1797839#M57121 Enlli 2025-06-14T07:08:17Z
