I have an unlocked Samsung Galaxy S8 on Vodafone. The SIM Card is old (pre-2018).
Since 7th February 2024 I am unable to make or receive calls at work. Previously I always had good signal inside and outside the building. Calls from my home are still ok. The features of this issue are:
- on trying to call out, no ring tone is heard and the phone app stops attempting to connect after a few minutes
- occasionally I heard 10 pips, before the phone call drops out, without connecting.
- I have once (in the late evening) managed to make a call, which went straight to the recipient's voicemail with no preceding ring tone.
-I managed two, very poor quality calls outside today. Yesterday I tried multiple different locations outside and was unable to make any calls
- at home calls work as normal
- I always get fair to good signal both at home and work.
- I can still text and use messenger apps and access the internet
The timing of this seems to coincide with Vodafone switching off 3G network, so I suspect the issues are related. Today we were also informed by our IT department that Vodafone network has problems affecting both personal and company phones. However, the problems I am experiencing already started last week.
I have tried the following:
-activating WiFi calling (makes no difference)
-resetting the network settings (as advised by Vodafone support via the chat function)
-removing the SIM card (as advised by Vodafone support via the chat function)
-restarting the phone before trying to make a call
Network settings are currently:
-LTE/3G/2G
My plan includes 4G calling (VoLTE) but this does not appear in the network settings. I understand Samsung S8 can make VoLTE calls, so this appears to be an issue with the SIM/Vodafone settings.
Any advice would be much appreciated, othewise, it looks as if I will have to switch network as I need to be able to make calls for work, so this is causing quite some issues. I'm happy to provide further information if needed. Thanks in advance!
