The promotion starts on 21 March 2016 and runs until midnight on the 21 April 2016.
If you’re one of the first 4,500 customers to order a contactless SIM as part of this promotion, you’ll receive a text containing a £5 Starbucks voucher link within three days of placing your order. You then have two weeks to claim it in any Starbucks store.
The voucher can either be printed off or you can just show it on your mobile. Only one contactless SIM can be ordered per person.
