Absolutely. Because SecondSIM operates on a real UK mobile network (not VoIP or a virtual app), all major banks (including Monzo, Starling, Barclays, and HSBC) recognize it as a legitimate mobile number and will successfully deliver SMS verification codes (OTPs).

Yes. This is a 100% real, carrier-grade UK mobile number. It is not a VoIP (Voice over IP) or "virtual number" which are often blocked by services. It works exactly like a number from a major carrier, which is why it's trusted by banks, WhatsApp, and Google.

All plans include the exact same features (a real UK number, unlimited incoming SMS, guaranteed verification, and no contract). The only difference is the billing cycle and the discount applied. The quarterly plan saves you roughly 10% compared to monthly, and the yearly plan offers the maximum discount, saving you over 15%.
