Will 5G really save us £6bn?

Top SIM Only unlimited data deals for November 2017

Monday, 6 November, 2017

Finding good value SIM Only unlimited data deals is like chasing unicorns.

Most of the time, they don’t exist. And when they do, on closer inspection they’re more like a donkey with a horn strapped on.

There are plenty of double-digit data limits, from 30GB a month up to 100GB a month, but they are few and far between and not the best for value.

This is because data is one of the most expensive things things that mobile networks offer.

So unless you’re willing to tie yourself down to a 24 or 26 month contract, often you can’t get uncapped or unlimited data.

Thankfully, we’ve got the best SIM Only deals with unlimited data right here, all wrapped up in a neat little package.

How to keep data use down

It’s not hard to chew through your data every month, even with the amount of free WiFi out there in bars, on buses, in restaurants, cafes and supermarkets.

That is, unless you live in a rural area, or you’re constantly travelling without access to WiFi, or you’re just streaming Netflix in HD on a constant loop.

The rest of us should at least consider turning on WiFi when it’s secured with a password, and grabbing the free data bump it gives us.

To answer a commonly-asked question: WiFi data does not count towards your data limit. Your phone is using WiFi instead of your mobile network’s internet connection.

Just make doubly sure the app you’re using is restricted to only use WiFi.

Giffgaff Always On Data

  • Runs on the O2 network
  • 30 day rolling contract
  • Unlimited texts, unlimited calls
  • Free calls and texts to other Giffgaff numbers

If you need unlimited data, GiffGaff’s £20 a month SIM Only deal is the cheapest way to get it.

While you can’t get all of the perks of the Three deal below, the fact that it’s on a 30-day rolling contract means you do have more flexibility to switch away if you see a better offer elsewhere.

The only restriction you have to worry about is the 9GB limit.

After you’ve used 9GB of data at unlimited 4G speed, Giffgaff apply a restriction. From 8am to midnight you’ll only be able to get a maximum 384kbps data speed. This is not fast enough to stream HD video so you will probably see more buffering at this level.

Three All You Can Eat Data

  • 30GB Personal Hotspot allowance. If you want to use your phone’s data connection on another device, for example to get online on a laptop without an internet connection, use Personal Hotspot. This is also called tethering or data tethering. If you’re uploading large files all day your allowance will run out pretty quickly, but for emails and general work 30GB a month is a healthy amount.

  • Available on 30-day or 12 month contract
