All I get back is "oops, something went wrong!" 2. An on-line chat but after just over an hour I had got nowhere, so I just gave up. 3. Hi @snellmark. You don't need a PAC to transfer from Voxi to Vodafone, they are the same company. Vodafone have made changing from Voxi to Vodafone and Vodafone to Voxi simple and you continue to use the same SIM card. Just take out the plan you would like with the number through Vodafone and they will make the change. VK5pWI.
