I'm looking at new Android phones since the battery life on my 5-year-old phone is getting quite dismal and it seems to have a lot of issues running out of RAM lately.
There just don't seem to be very many phones with two sim slots AND a dedicated sd card slot these days. I need all of them since I have one sim for talking and texting and a separate limitless mobile broadband sim that can't make phone calls as well as a chunky SD card that I use for photos, video, media, game roms, etc. Unfortunately most lower-to-mid-range phones just have a hybrid slot at best (while high-end phones seem to have eliminated expandable storage completely.)
Basically, I'd have to ditch the internet, having extra storage or the phone's actual function as a fucking phone. The phones I found that do have the slots I need meanwhile somehow have worse specs than my current phone from 5 years ago 
I guess I could always just carry two phones with me 
I remember replacing a carberator with my dad on our car as a kid and those 2 weeks were the most fun I ever had with him.
