Hi, 

 

I have had a Samsung Galaxy Note 20 Ultra for a while now. Love the phone, its a great phone. However I have started having connectivity issues with my phone. Unless I am in a WiFi area and have WiFi calling turned on, the phone becomes useless for calls and connecting with people. 

 

As soon as I am off the WiFi my SIM status changes to:

 

Network - unknown

Mobile network state - disconnected 

Service state - no service 

IMS registration status - not registered 

Mobile network data type - unknown. 

 

When I turn WiFi and WiFi calling back on it all goes back to normal except for mobile network state which is permanently disconnected.

 

I have tried everyone online has suggested. I have restarted the phone, reinserted the SIM card, reset the network and APN settings. I have even changed the SIM card and put it into a different phone and still the same so I know it isn't a hardware issue or a SIM card issue as both have been changed. 

 

I tried talking to o2 but they said it was because a mast was down that day (its been like this for months) and maybe I needed to change the SIM card (already done that). 

 

Does anyone have any ideas. At the moment I don't want to stay with o2, want to change and start again, but they want nearly £500 to cancel my contract...even though I get no connectivity or use out of the phone if I'm outside of WiFi. 

 

Thank you 🙂

Hi, 

 

No I haven't asked Samsung yet, as I believed it to be an issue with my o2 account rather than a hardware issue given that I have tried on more than one phone.

Have you checked for issues here O2 Service Status ?

Yes checked that, a lot of people I work with are o2 and they have no issues. This has been an ongoing issue for around 6 months now.

Has to be an account issue then or your phone is barred.

You need to contact O2.
Message them on Social Media. Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) or give them a call on 202 or 0344 809 0202

You could get a PAYG SIM from another network and try that in your handset ; if it works OK, you will at least know that it is not a hardware issue.

I had the same issue. Finally got a solution after 3 months.

 

Very inconvenient, but I got O2 to disconnect then reconnect my number.

 

So far it seems to be working perfectly again.
