Apple Watch Ultra Cellular Connection Problem

I bought an Apple Watch Ultra with high hopes, but due to a persistent cellular connection issue, I've had to use it like the Watch SE. Despite numerous discussions with both Apple and Turkcell, a solution has yet to be found. If you're in Turkey and thinking about getting an Apple Watch, my advice is simple: avoid the Watch Ultra. It's a shameful waste of money. Choose the Watch SE instead, as the cellular feature is essentially useless in Turkey, making both models equally effective for most users. My experience has left me frustrated and disappointed, especially given the Apple Watch Ultra's high price tag. I hope that others can learn from my experience and make an informed decision when purchasing an Apple Watch model in Turkey. If anyone has found a solution to this problem, please share your knowledge with your fellow Apple Watch users in Turkey.
