Consumer groups have criticised mobile phone networks for not offering unlimited data plans on 4G - which gives faster mobile internet speeds.
All the major networks are due to launch 4G before the end of the year, only Three has said it will offer unlimited data.
Ruth Schofield, 22, from Leeds has been using 4G on a contract for several months. She pays £36 per month for 750MB of data, unlimited texts and unlimited calls.
She says the faster connection means she finds herself using more data - and told us networks should offer unlimited allowances.
