TalkTalk Mail is available only for UK residents. TalkTalk MailPlus is required for former customers leaving TalkTalk broadband and this must be paid from a UK Bank Direct Debit. Use of TalkTalk Mail from overseas locations can be subject to rate limiting meaning that the number of outgoing mail messages can be significantly reduced.
My advice is to use a Gmail email account for the country you're moving to.
Use of your UK TalkTalk Mobile 'phone service in the EU will be on a roaming basis that you'll need to set up in advance.
My advice is to apply for a SIM card from a mobile 'phone service in the country you're moving to. You'll not be able to retain your UK mobile number.
