Most smartphones (including iPhones) can serve as “wifi hotspots”

In effect, this means that the phone is acting like your wireless router at home. It can be used to allow you to connect another device to the internet (eg a laptop or a tablet) when a “normal” wifi connection is not available and when the laptop or tablet does not have its own 3G internet connectivity.

Turn on HotspotWhether this will work with your smartphone depends not only on the hardware but also on the deal you have with your mobile provider. If your phone was supplied by your provider then it’s possible they have “crippled” this feature so that it won’t work. On an iPhone, for instance, the option to turn on the personal hotspot connection may be “greyed out”. You can find this option by going to Settings and then Mobile. If yours is greyed out, my advice is to speak to your provider as they may offer a deal whereby it can be turned on.

Assuming that you have Personal Hotspot enabled on an iPhone or on an iPad with cellular access, and you wish to use either of these devices to pass an internet connection to your Macbook Pro or Air, this can now be done without even taking the phone out of your pocket. In other words, you don’t have to turn on the “Personal Hotspot” feature on your iPhone and then connect the computer to it. This new capability is known as “Instant Hotspot”. It’s part of the latest round of updates to Mac computers and devices (called “Continuity“) and it will only work if you have OSX 10.10 or later on your computer (ie the new version, known as Yosemite) and version 8.1 or later of IOS on your iPhone or iPad.

I learned the above from the blurb that Apple and various blog sites told me. So then I tried to test it – just to make sure that I’m not telling you porkies. No joy. If I manually turned on the personal hotspot on my iphone, the Mac recognised it with no problem. To do this, all you need to do is simply click on the Wifi icon on the Mac and there it is – offered as one of the available wifi connections. To try to encourage Instant Hotspot to work I tried turning off my router, just in case the Mac was favouring that over other connection possibilities. Still no joy. Then I checked the versions of the operating systems on both Mac and iPhone. Both were definitely up to date.

After much googling (and not a little profanity), I eventually found a site that tells me that the Mac needs to be 2012 or later for it to work. So, if you’ve got a Mac that’s older than that then maybe reading this blog will save you a bit of frustration – it’s not going to work. Pity that Apple didn’t make that clear in their blurb.

Look for HotspotSo, for the rest of this blog, I’m just winging it and hoping that what I read is true for Macs of 2012 or later vintage. All you have to do is click on your Wifi icon at the top of the screen and your iPhone should appear as an available network. It doesn’t even ask for a password. It doesn’t need a password as it will only work if both phone and computer are logged into the same iCloud account. After a period of inactivity, the connection is automatically dropped. This is to save the battery on the iPhone.

Instant Hotspot

Just have your iPhone reasonably close to the Mac when you look for the Instant Hotspot

It’s worth mentioning here that mobile data allowances aren’t usually very generous in comparison with your home or office broadband, so do be careful. You can always check how much of your download allowance you have used by going to Settings on the iPhone, then take the Mobile option and scroll down to the figure headed “Mobile Data Usage”. This will only be meaningful if you reset the statistics at the beginning of your “billing period”. My understanding – at least with T-mobile – is that the “current billing period” is a calendar month and not the month from one payment date to the next (but I wouldn’t actually stake my life on that being true).

Something I came across more than once when researching this item is that an initial connection to an “instant hotspot” is sometimes difficult. If this happens, the recommendation is to manually turn on the personal hotspot (on the iPhone) and make a connection that way first. Thereafter, it seems that the Instant Hotspot is more likely to work.

I’ll have to take their word for all this as I’ve got absolutely no need (otherwise) to update my perfectly good five year old Mac.
