Switching to mobile broadband would save me some money each month, but more so if I combine this with my phone service which I get from another company. However, this would mean getting a smartphone; I've only ever had what can loosely be described as a dumbphone as I like to access the internet using my computer, and services through websites instead of apps, although I see some benefits. Now buying a low-priced smartphone and using that as a wi-fi hotspot would actually work out cheaper. But which phone to get?

I like my phone because it's cheap and has not suffered too badly from being knocked about over the years; I fell down a mountain with it in my pocket and it survived that when my camera didn't. It has been in many a wet pocket and soggy bag, and has been dropped a few times.

Some features I like but are hard to get are:
 - 3.5mm headphone jack (TPPM)
 - FM radio

Providing the phone has a good enough spec for it to work well enough I'm not bothered too much. And a version of Android that isn't going to be rendered obsolete within a year. A microSD card slot would be preferable. Here's what I've found:

So far the HONOR X6a looks to be the phone of choice for me. I assume wi-fi hotspotting is a setting available to all such phones these days.
