Worldwide Roaming Charge applied incorrectly

Recently whilst travelling on a ferry between Hull (UK) and Rotterdam (Netherlands), and whilst my phone was inside an inside cabin on the ferry, i.e. within a giant Faraday Cage, my account was debited for £10 worldwide Roaming charge - £10 being the cap value I had established. This was at the time when my phone had “No Service” and i was asleep overnight.

The ferry route from the UK to Netherlands would not have allowed the phone to “see” any cell towers in non EU countries, indeed the Faraday Cage would have prevented the phone from seeing anything.

Why then have I been charged this additional £10?

Hey there ​@James8, you would have been charged for connecting to a network whilst roaming out at sea I’m afraid, whether that been for a split second or not, as roaming charges for the maritime network are quite high I’m afraid.

 

To avoid this in the future, we’d simply recommend turning your phone on flight mode, setting your bill cap to £0.00, and/or turning roaming off whilst out at sea, to stop your phone from connecting or being charged at all.

 

Thanks,

Tyler

    I recently went on holiday to Croatia. I have been charged £25 for roaming in non European countries. I went on a day trip on a boat that did not leave Croatia. Would this be it? That's terrible if so. I remained in Croatia!

    Hi, ​@Lou J Vincent 

     

    Thank you for getting in touch. I understand your concern about the £25 roaming charge while you were on holiday in Croatia.

    If your day trip took you outside of Croatian territorial waters or into international waters, it’s possible that the network you connected to was classified as a non-European roaming area, which could explain the charge. However, if you remained strictly within Croatia, you should not have been charged for non-European roaming.

    I’d be happy to look into this further for you, please send us private message on our Socials (Facebook or Instagram), Live Chat, Community or email us at socialqueries@idmobile.co.uk, outlining the details of your query, we would like the opportunity to put things right.

     

    Thank you,

    Zandile

    Landed in Thailand with data roaming switched off. Been here 3 days and switched in on for a couple of minutes and now have 2 texts telling me I have been charged at least £45. How can this be if data roaming switched off?
