Turkcell 4.5G Constantly Disconnects Leaving Me Without Reliable Internet

I made the switch to Turkcell 10 days ago, hoping for seamless connectivity, but it's been nothing but a headache. Even though my phone indicates a solid 4.5G signal and there's coverage from the base station, I keep experiencing frequent internet disconnections. It feels like the connection just drops out of nowhere. I'll be offline for about 30-40 seconds, and then it comes back on its own. This isn’t just a one-off thing; it’s been going on all over Istanbul. It’s super annoying when I’m trying to complete a bank transaction and suddenly lose connection, leaving everything hanging. I joined Turkcell expecting dependable service, but honestly, it’s been quite the letdown so far. I hope they can tackle this problem or come up with a solution because I'm feeling quite disappointed.
