A54 not registering on O2 network on wifi calling

(Topic created on: 15-04-2024 05:28 AM)

I live in an area with no mobile signal. I bought an A54 from Argos and took out a contract with O2. Wifi calling works until my phone reboots. Then the O2 network is lost and I have to drive 2 miles to an area with an O2 signal to register on the network. It then works until the next reboot. I have had 3 months trying to get O2 support to fix this but after trying everything suggested I'm in the same place. O2 initialy blamed the Broadband service, but it's same when I try on friends Sky WiFi connection. Friends can reboot their phones on my Vodafobe broadband wifi connection and make calls. After several calls from the so-called O2 guru the blame was laid on my A54. My wife has an A51 on O2 and has the same issue. Anyone else had this?

I'm sorry to learn your experiencing these issues 😔 

If you've also spoken to Argos, what has Argos said who supplied the phone to you ?

I haven't owned that mid range model of Samsung phone unfortunately so cannot share my experiences with that model. 

The contract with o2 may I assume is a monthly contract as your using Wi-Fi Calling. 

I use o2 Pay as You Go  and cannot use that service. 

However there are other networks I believe that let payg users have Wi-Fi Calling.

I would have used one of those so not to be locked into a contract that I can't use at home. This is in no way criticism directed at you.

It's possible the phone struggles to provide a connection if there is not a hint of network connection to then instigate Calling over WiFi unfortunately or it's an o2 sim problem that won't allow it. 

If I can be of any further help then please don't hesitate to ask.  😎

The advice I offer is my own and does not represent Samsung’s position.

In addition to the excellent advice from BandofBrothers and this is reliant on a strong wifi connection.

Settings>connections >tap wifi calling>tap 'calling preference'>ensure 'wi-fi preferred' is ticked.

Thank you. We tried everything O2 support and others suggested to no avail. Friends who have visited the house have tested with a number of different combinations of phone and service provider and all work okay.
