Hello,
I got a new O2 sim recently and the cellular reception in my apartment is terrible, so much so that I only ever get 2G data speeds. As for network coverage, I never get more than 2 out of 5 bars. The phone never switches to 4G which makes the internet unusable. This is unexpected because, I got the sim card after checking O2 coverage in my area on https://www.o2online.de/service/netzabdeckung/. I also checked if there is any temporary service outage on https://www.o2online.de/service/netzstoerung/?partnerId=SocialMedia&medium=socialpost&campaignName=CM-Commerce
But there are no reported problems. I have tried changing the mobile network mode settings on phone to LTE and 3G only. but that didn’t work either. Please help. My location is Falkenweg, 72076 Tubingen.
Thanks
Shashank
