I was with EE and have my home phone and Internet with BT. So I check it out and wow.
I have got 2 sim only deals with 15gb, unlimited texts & calls for £31 a month (for both) PLUS for each sim I get a £55 iTunes/Amazon voucher
Then I got 2 sim only deals for 500mb, 400 mins & unlimited texts for £5 a month each PLUS for each sim I get a £10 iTunes/Amazon voucher. Conclusion-for what I was paying with EE for one sim and 16gb I get all of the above AND £130'vouchers! It's only valid for another 2 days so hurry up if your looking at a new deal.
