For some reason my A15 works far better than S series S24 ultra when out in the country as I live in a rural area. Ther are issues with connection to calls with streaming and with vid calls. I live near a mountain range could this have something to do with it for some reason? My A15 can go for 10 hours with no issues it may seem like a silly question but it's just something I have noticed over-the last couple of months. Any answers would be appreciated thanks.
If you had different Sim cards that may be the problem, try finding out what Sim card it was. If it was the same Sim card it will be a thing for the phone, My phone works better then most phones (A15) so you might have to consider changing for better data if getting a different Sim card dosent work
