Keep your privacy.Secure Your UK E-Commerce Store with a Real Mobile Number
Give marketplace buyers and store customers a dedicated UK support line. Pass Amazon, Etsy, eBay, and PayPal seller verifications without ever exposing your personal mobile.
Three problems, one line
Marketplace OTP blocks
Cheap VoIP apps are flagged and rejected by Amazon, eBay, and Etsy. SecondSim is an authentic UK mobile number on Vodafone that passes strict merchant verifications natively.
Buyers messaging your personal phone
Don't publish your private mobile on invoices, store policies, or tracking notifications. Handle all customer support inside WhatsApp Business on your SecondSim line.
Bank & Stripe payout security
Protect your store's payout accounts (Monzo, Revolut, Barclays, Stripe) with a clean, dedicated mobile number meeting PSD2 and strong customer authentication standards.
“Amazon flagged my previous virtual number during store re-verification. Switched to SecondSim — the OTP arrived in seconds and my seller account was fully approved.”
Live before your next sale.
Buy the plan, tap the 1-click install link, add WhatsApp Business or marketplace 2FA. Sixty seconds, no contract, cancel anytime.

Can I use this number to verify a UK Etsy, eBay, or Amazon Seller account?+
Yes. SecondSim provides real, carrier-grade UK mobile numbers (non-VoIP) on Vodafone's network. They are fully recognized and accepted by Amazon, eBay, Etsy, and Shopify for merchant identity and 2FA verification.
Will marketplace buyers see my personal mobile number?+
No. You use your SecondSim number as your public customer service line on your invoices, store contact page, and WhatsApp Business. Your personal mobile number remains completely confidential.
Can I receive SMS 2FA verification codes instantly?+
Yes. Because SecondSim connects directly to the physical cellular network switches, security SMS codes from banks (Barclays, Monzo, Revolut), Stripe, PayPal, and marketplaces arrive instantly.
Do I need to buy a second phone to run my store's customer service?+
No. SecondSim is an eSIM that installs digitally alongside your primary SIM card on your existing iPhone or Android handset. Both numbers work simultaneously on one device.
What happens if I travel abroad to source inventory?+
Your SecondSim eSIM allows you to receive incoming SMS verification codes and 2FA authentication for free while travelling internationally.
