Cart recovery on WhatsApp beats email open rates when the buyer already opted in at checkout. The message comes from a UK shop line on a real +44 mobile eSIM, which feels local and trustworthy. A virtual 5sim number usually cannot even complete WhatsApp registration.
Opt-in requirement
- Checkbox at checkout: "Send order updates on WhatsApp"
- Store phone in CRM with consent timestamp

Automation flow
- Cart abandoned 1 hour: gentle reminder with cart link

- 72 hours: final nudge, then stop

Line setup: BuyUKeSIM ($25, crypto, no KYC). Warm 2 weeks first: warm-up. Register: WhatsApp on eSIM. Avoid VOIP: virtual bans.

FAQ
