[Plugin: WP Mobile Detector] Best plugin for non smart phones

Hi,

I’m currently running WP Mobile Detector to have a mobile version of my site. My site will mostly be used in the developing world where smart phones are less common but standard phones with internet are very common. I haven’t seen any reviews of such plugins in terms of what would be the best for use on non smart phones.

It seems like WP Mobile Detector would be good for this from the descriptions I’ve read, but could anyone give me any further advice?

Also, I’ve seen articles such as this: https://crunchify.com/top-3-wordpress-plugins-to-make-your-site-mobile-friendly/ which describe their top 3 plugins. Should I only use one of these plugins or is it possible/is there any advantages to running more than one of them, or will they conflict with each other?

Thanks for your help.
