twelvesquid.online (twelvesquid.online) provides independent information about UK mobile networks. We are not affiliated with, endorsed by, or connected to O2, Three, EE, Vodafone, Tesco Mobile, Sky Mobile, Lebara, iD Mobile, VOXI, Asda Mobile, giffgaff, BT Mobile, or any other operator. We do not sell SIM cards, contracts, or devices. No specific pricing is displayed — tariffs change frequently; always verify current prices directly with the network. Calling our number or submitting our form reaches our independent guidance team only, never a network's support line. Network names and brand marks are trademarks of their owners, used solely to identify which network a page covers.

Safety: We will never ask for your OTP, online banking password, or full card number — on a call, by email, or anywhere on this site.
