While EE is both the UK's most popular network and the fastest 4G option, it is also usually the most expensive of the main four networks, sitting miles behind Vodafone, Three and O2. However, EE has recently stepped up its game, offering some bargains in the big data SIMO realm.

Over Black Friday and continuing through to the current day, EE had an excellent 60GB for £20 offer.

But now, it has taken that a step further.EE's latest venture comes in at 100GB for that same £20 a month, making this one of the best SIM only deals EE has ever put out.

Both Smarty Mobile and Three have some bargain prices that closely match this.
