Hi @Conor23 What network are you currently connecting to? Can you ensure you're connecting to SoftBank Corp. as they're our roaming partner in Japan 👍
Thanks @Conor23 Can you also ensure your data roaming is activated in the settings on your phone. Also to note 4G roaming is not available in Japan so can you manually connect to 3G. Let me know how you get on with this 😊
I'd like to look into this further for you @Conor23 Can you send a private message with your mobile number, name, address, date of birth and we'll get this investigated?
