Hi Just signed up for 15gb and unlimited calls and texts for £16 a month (-£5 as Bt customer). I have received the sim and I want to claim the voucher. My friend says I need to go to https://www.vouchers.bt.com/offer/mobileclaim
To claim my vouchers I choose. Do I have to wait until 14 days after my purchase or can I do this now. I'm 4 days in from purchase. Thanks for your help anyone?
