i personally don’t like to share my contact in fiverr customer, because it againts fiverr rule. but sometime i need to share my contact to my customer because i gave them warranty about error that might happen suddenly. my gig was about web development, sometime after system run well, in some case their web suddenly off. it can be many thing, like storage has been full, wrong database connection. since it was information system, then i must fix those asap.
i ever have client that nearly fire by his boss, if he cannot fix the issued in 1 hours, luckily i still wake up and still being check my fiverr account. imagine if i am not checking my phone, my customer would be fired. in that case, phone and personal contact was needed and crucial. except fiverr gave their android apps and microsoft store apps ability to contact or calling like whatsapp or telegram so in any case, if we need to fix asap, then it doesn’t need personal contacts.
