Switched to O2 now very bad signal

[littlebadger]

I was switched over to O2 last night and now I get no signal downstairs and just one bar if I stand by my upstairs bedroom window.
I have restarted my phone and still the same.
I tried to register with my O2 account but they send a verification code to my phone and guess what? I get no signal so it doesn't come through.
I have a phone that does Wi-Fi calling but if I go into my phone settings to access it I get "Call settings error   Network or SIM card error".
Do I need an actual O2 sim in my phone? I have a LG G7.

Hi, littlebadger.
Thank you for reaching out to our community and help forums - we're sorry to hear of the issues you've had since we switched to the O2 services for your mobile.

We'd love to help, we'll need some more info confirmed so we can do this.
Could you please check the O2 coverage in your area here and let us know if any known issues come up?

Also, does the issue appear to be in a single location or everywhere and have you contacted our O2 mobile at 202 to get further help with this so far?
If so, what was advised?

Lastly, do you have a physical SIM or an e-SIM in use currently so we have this clear?
Cheers,

Seems to be no issue with O2 in my area according to the link.
At the back of my garden I get two bars.
I haven't contacted O2 as I get almost no signal indoors.
I have a physical SIM card.
I can now access additional settings in Calls but Wi-Fi Calling option is now gone.

I have now ordered free sim cards from Vodafone and Three to see if I get better coverage.

Thank you for the updates and sorry to see you had to order more SIMs to test the coverage.

What did our O2 mobile team advise about the signal issues and the errors you experience, if we may ask?

Also, you can ask to send you a replacement SIM if we find this is faulty or causing issues with your signal - was that discussed as an option over your call?

Cheers,

I can't make a call as I have no signal.

I would also like to add doing anything like this online needs a two step verification where a code is sent to your phone.
I don't get the code as I have no signal.

Sorry to hear this, are you able to contact the O2 team at 0344 809 0202 from any other phone in this case and let us know of the outcome so we can see if further support is needed?

We'll be here to assist more where needed.

The signal on O2 should be exactly the same as when you were on Virgin. However, sometimes Virgin SIM cards don't play nice with the change

If you can get to an O2 store with photo ID they will replace it with a proper O2 card

Did O2 send you the password that you need to log into MyO2? If they didn't you'll need to wait until you get a payment reminder email to be able to get your O2 account number as you need to know the account number before you can reset the password
