Problem with 4g connection

[Anonymous]

I recently bought a Sony xperia xa1. Since the very beginning I had problems making phone calls over Skype using my broadband data. I use Skype often ringing abroad and it's very frustrating. Whenever I try to make a call I get disconnected because 'Internet connection is too weak'. I could have 4 bars of signal, yet I can't make a call. There is no problem using WiFi though. Is this a device fault?

@Jay6 - are you in a 4G calling area?
You say that you have tried a different sim - whose was it?
Did they have 4G calling enabled on their account?
If it worked with a different sim but not yours, then it suggests there is an issue with yours - either you do not have 4G calling enabled, or there is a fault with your sim. To rule out a fault, get a new sim either by calling customer services on 202 or pop into an o2 shop.
If you call, you can also check they have enabled 4G calling (or you can check in the My o2 app).
@Anonymous - are you having problems calling when connected to your broad band or over 4G? Who is your BB provider and what speed do you get?

@Jay6
No problems using BB, I'm with virgin and it works fine over WiFi . It's only playing up when I'm using 4g.

i have tried all the options 

new sim card

wifi call enabled

4g enables

the area i am calling from had full 4g reception 

like ive said i had no issue until about 5 weeks ago!

i will most probably move networks as i use the skype internaitoanl calling to landlines frequently.

Its dissapointing that o2 cannot get this resolved as i have been with o2 for the past 15 years,,,

Where to check whether 4g calling is enabled? I looked on myo2 app and can't find it.

It’s combined with WiFi calling.

@Jay6 Is 4g calling enabled in in your area not all 4g areas are volte enabled as yet https://www.o2.co.uk/coveragechecker use your full postcode for accurate results

I have full 4g access at home

I tried a Virgin sim card on 4g and had no issues connecting.

Full 4g access not the same as 4g calling coverage

I spoke to O2 guru over the phone and he told me to get a new sim as this could be a problem. If that doesn't help they will need to look into a handset as it might be faulty.

Hi. I have the same issue with Skype on 4g. The other party can hear me fine but I don't hear anything and it disconnects me after 10 seconds or so due to connection being to slow. There is definitely problem with o2 servers. When I use VPN on 4g Skype is working without issue. I think O2 limits the bandwidth for Skype making it unusable.
