There could be a few reasons why you have not received a code. Firstly, please check if the number you have input is correct. Next, you will need a cellular connection in order to receive a code, as it comes via SMS. Lastly, your network may have a bar on receiving certain types of SMS messages, meaning the verification code is unable to be delivered to your mobile device. You can check this with your mobile network provider, or you can contact 5’s Customer Care Team.
