iPhones are OK if you can get past the "I hate Microsoft / Apple / Google etc" thing. My eldest son has a Samsung Galaxy S7 which is amazing and he prefers it to his previous iPhone.
No point getting one of these if you just phone and text. But with a smart phone, you get free sat nav (voice guided, turn-by-turn – free), Google, news (when waiting / on train / queue etc), emails, social media, ebooks, ME / MEW digital editions(!!), music etc etc.
I also use my phone to stream music to my workshop hifi, it's my alarm clock, I don't use a camera now (the iPhone is better then most compact cameras), online banking (the banks consider it safer than a PC), Apple Pay (unlimited, unlike contactless cards with only manage £30), remote control of the central heating, remote access to my NAS storage, remote control of the sockets in the workshop (turn them off automatically at 11pm each day), Find Your Friends shows where the kids are (if they let you),
Most of the couriers send updates on deliveries through email / text / apps which is handy.
Abroad you can use Google Translate to translate voice and text (from your camera) in real time from live video (try it – it's amazing and even works in places like China).
But if you want to make calls and texts, get a simple phone. Horses and water…..
If you don't want to spend a lot, get an older model iPhone or Samsung. Yo could get something pretty decent for £200 or so. You only need large memory if you want to store loads of music and video.
