iPhone SE has poor cellular data connection in mountainous area

I've been traveling the last few days, several hundred miles from my home. I normally have little or no trouble connecting to the Internet or using my iPhone in any way while away from my home WiFi network, but on this trip I've rarely had access outside of my hotel room and the hotel WiFi. I've either had an extremely slow connection, to the extent that I usually gave up trying to load a page and look up some information. At other times, the screen has displayed a message saying I'm not connected to the Internet. I set the phone to roaming and using cellular data, I've tried turning it off and on multiple times, I've looked at help articles, and nothing seems to improve my service. Today I tried repeatedly to text a photo and don't think I succeeded until reconnected to the hotel WiFi. Could the problem be related to the area I'm visiting? I currently in a smallish town in a mountainous area. I don't necessarily expect a connection when driving or hiking far from any community, but I'm not getting good reception when I'm in town either. The service is fine in my hotel, but a mile or two away at restaurants, etc. I can't connect. My husband and I use the same mobile provider, although he has an android phone, and often he can connect when I can't. I have an iPhone SE, iOS 26.6.2, that's around five years old. Could the phone be "wearing out"? I'm glad I haven't needed to use a phone for anything crucial (e.g., paying for something), since more often than not it's been a piece of useless hardware.

Mountainous regions are uniquely difficult for cellular connectivity, unless the region is highly populated and there are cell towers a plenty to pass the signal as you travel. If you're in a relatively remote mountainous area, it would make total sense cell service is spotty and slow.
