Hi, in the last 2 mounts I can say your mobile internet speed is on the ground, I believe firm when you merge with O2. All my video calls are lagging so bad until disconnect. Image is so unclear and sound is coming with delay and fast talk speed very bad user experience.
No matter where I am in 4g or 5g is same I tested the speed last night was download 1.5mb and upload under 1mb.
Today I nearly got 10mb but up to the end of test went to 5mb.
I restart the phone clean my sim I got a new SIM still same issue. When you was with Vodafone was great speed no issues.
What can I do to improve this service.
