Hi ​@Jacob_8149,

 

Kindly note that Saint Lucia isn't included in iD Mobile's roaming destinations, so there isn't a Roam Beyond add-on available for use there.

 

If you'd like to use your iD Mobile service while in Saint Lucia, you'll be charged at our standard roaming rates. To do this, you'll need to have a bill cap in place.

 

How to check or change your bill cap:

  • Log in to the iD Mobile app or your online account.
  • Go to Bills.
  • Select Manage Bill Cap.
  • You can adjust this using the slider or by entering an amount (between £0.00 and up to £75.00, depending on your account type).

 

The current standard roaming charges are:

Roaming Pay monthly
Calls to UK* £2.40
Calls to Saint Lucia* £2.40
Calls received* £2.40
Texts to Saint Lucia** £0.60
Texts to UK** £0.60
Picture message (MMS) sent** £0.60
Internet and Data (per MB)*** £1.50

 

* Price per minute.

** Price per message / text.

*** Data is charged or deducted in one kilobyte (KB) increments and any part KB used will be rounded up to the nearest KB.

 

For more information, you can visit: https://www.idmobile.co.uk/help-and-advice/international-and-roaming-charges.

 

Because data is charged at £1.50 per MB, we'd usually recommend purchasing a local SIM or eSIM while you're in Saint Lucia, as this is likely to be much more cost-effective if you plan on using mobile data.

 

If you have any further questions, feel free to respond here or pop us a message on live chat - https://www.idmobile.co.uk/live-chat  - we are more than happy to answer any further questions you may have.

 

Regards,
