At first, Cara Selway was confused when she started getting texts like "Hey hot vodafone boy" and "I have some whitebait fritters for you" from random numbers at the weekend.
Soon the university student was getting hundreds of messages from unknown contacts - it turns out her number is just one digit different from the one Vodafone is urging people to text in its latest television campaign, launched on Sunday.
"I eventually figured out what was going on after Googling the ad. But because I wasn't responding, people kept text-bombing me, like four or five texts in a row saying, 'What's going on? I thought you had to text back!'
"So I eventually started texting them back but then the people would say, 'Oh, well I want to talk to you now, who are you?' and so on. It's been a wee bit excessive," Ms Selway said.
By yesterday evening, the 24-year-old, from East Auckland, had already received at least a couple of hundred texts from people mistaking her number for the one on Vodafone's television commercial.
