To three or not to three that is the question

I'm thinking of getting a contract sim for my mobile. I see that Three have a package for £6.90 per month. Does anyone else use Three? Are there any issues with them?

ma aul man his 3 fer his work phon an times ah text an hell no get it fer days cuase ahm virgin but thats peblees seems tae be ok oot doors but iffy indors
mind were no on thae smertphones were jist ornary kinds

Thanks. After persuading Moira to change to a smartphone last year, she
liked it so much she then persuaded me to get one. I'm now thinking
that I hardly use my phone because it is pay as you go and the phone
calls are expensive. I've now decided to bite the bullet and Three's offer
of 500MB of data, 200 minutes and 5000 texts for £6.90 a month sounds pretty
reasonable.
