My 12 month EE SIM only deal is due up now so I've tanken out a Virginmedia SIM only deal for £5 a month.
It's 2Mb of data, 1000 minutes of talk and unlimited texts.

EE offered me the same deal to stay (would normally cost £9.99).

What's funny is that I'm now on a flexible 30 day rolling tariff that still uses the EE 4GEE network.

My advice when it comes to changing your tariff - haggle - no tariffs are set in stone.
