Dropping in to put in my two cents ![]()
Google has started moving towards dropping the MicroSD card on Android devices (*points at Nexus 7*), with the goal of using cloud storage as an alternative, this means that tablet data usage is going to soar, most likely on the next wave of Nexus devices due out in December this year. With this in mind you can pretty much categorically say that no, 3GB will not be enough.
Ignoring the whole cloud storage thing for a second, 3GB still ain't enough, sorry. It just isn't.
Lets demonstrate this with an example, youtube!
I looked at a video review, it was 5 minutes and 48 seconds long, the download size was 58.35MB at 720p
Using these numbers we can make a reasonable estimate that watching youtube at 720p exhausts around 10.06MB/min of bandwidth
Given our 3GB download limit, this gives us around 298 minutes of youtube viewing every month, or a mere 10 minutes a day. Given the average length of a youtube video (around 4 minutes), this means you can watch 1-2 youtube videos a day, any more than that and you'll go over your limit before the end of the month.
This is all without even accounting for anything else you might use your tablet for, such as video calling (skype), browsing, app downloads, etc. All things that are commonplace these days. These things will knock a huge hole in your bandwidth, making that 10 minutes a day much lower, and again as I previously mentioned, this situation is about to get astronomically worse with Android forcing everyone into cloud data storage and video streaming.
As for the competing offering from 3, it's a monthly rolling contract much like giffgaff is, you are not tied in, and of course the £/GB is far better on the three plan, if someone was asking me what plan to get on a tablet, I certainly wouldn't be recommending a 3GB plan, I really like giffgaff (I use it on my mobile and love the unlimited bandwidth) but the data offerings simply are not useful unless you are the type of person that sits at home on wifi the majority of the time.
Before you jump in and say "BUT YOU CAN USE TEH WIFIZ!!!11!1!1", I feel the need to point out that...if you can use wifi all the time I'd be dubious as to if you needed a mobile plan at all, or a tablet for that matter. The whole point of mobile devices with mobile internet connections is to enable you to be mobile, they are rather pointless if you spend the majority of your time holed up in your house, using your home connection. You may as well just have a laptop or PC, which are far more powerful than a tablet.
As for the pricing, a quick review of a price comparison site reveals that all 3 of the giffgaff deals can either be matched or beaten by other provides, so at best giffgaff is simply matching the competition rather than beating it.
tl;dr 3GB is /NOT/ enough already, and the situation is only going to get astronomically worse in the near future. As per the thread title the giffgaff goodybags are indeed not that great, and need to be heavily supplemented with wifi usage in order to be usable by even the average user (lets not even touch on heavy users) in todays world. The pricing isn't amazing either, and a tiny amount of extra money will get you far more bang for your buck.
With giffgaff I can tether my tablet for £20 a year. How can you do that on 3?
(Order a sim through my phone referral link, activate with £10 gives me £5 free credit so I can buy three months worth of goodybags, and the £5 referral payback means it's only cost me £5. When the 3 months are up, repeat with a new sim)
