As an example, I was out and about, and wanted to show a friend some furniture that I had been looking at for the first iTandCoffee shop (opening in August 2015 - more on that in coming weeks).
I had 'pinned' various website images to my Pinterest board during days of online searching for ideas.
For those of you who don't know, Pinterest is a great tool for creating a visual index/reference to all sorts of images and information that you find on the internet, or that you upload from your from your own photos. Great for holiday planning, renovation ideas, recipes etc.
I thought that maybe I had logged into a different Pinterest account on my iPhone to that which I was using on my computer, and figured I would just have to sort it out later!
Of course, I had a 'duh' moment a bit later that day, when it dawned on me what what preventing my boards from showing.
I had turned off my Cellular Data for Pinterest (and many other apps) when overseas recently, so I was only able to access my 'boards' when I was Wi-Fi, and not when I was out and about on 3G/4G.
This was easily fixed by going to Settings -> Cellular (or Settings -> Mobile for some devices).
The list of apps that would like to use Cellular data is shown in the bottom part of the screen. By turning my Pinterest app to on, I will will now be able to view my ideas when on the go, using my cellular data.
(But just be sure you have enough Cellular Data to support apps like this before you turn it on. Some apps - are very data hungry and can use up your data allowance before you know it!)
