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?
Please note, this is not customer services and we cannot access your account. Do not publish personal details (email, phone number, bank account).

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,,,

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.
