Ahh - so I just found out...
[Amit] Hello Ally, how are you doing today?
[Visitor] I'm fine
[Amit] That's nice. So how may I help you today?
[Visitor] I want a Data SIM that can be used in the UK and Ireland for my tablet, I have been hearing that THREE do one where there is no extra charges for roaming?
[Amit] I'll be glad to assist you today with the required information and thank you for showing interest in us.
[Amit] I need to firstly know if your Tablet is unlocked and 3G compatible?
[Visitor] It is.
[Amit] Great! We do have Euro Internet Pass service.
[Amit] I'll brief you about the same.
[Amit] May I know if you wish to use your tablet in the UK as well as Republic of Ireland or Northern Ireland which is already a part of UK?
[Visitor] I live in NI and wish to use it also in ROI
[Amit] The inclusive monthly allowance can be used any where in the UK including Northern Ireland however if you wish to use your tablet in the ROI then you need to order a special service which is know as Euro Internet Pass.
[Amit] However this service is only available only for Pay monthly voice customers (on your phones) and can't be used for broadband or tablets.
[Amit] So are you already with Three on a phone contract?
[Visitor] No
[Amit] If that's the case then you need to order a new mobile broadband Sim Only package for your Tablet.
[Amit] You can use your inclusive internet broadband allowance only when you're in the UK and Northern Ireland.
[Amit] In case if you wish to use your same Tablet in ROI then you'll be charged as per International data roaming charges.
[Amit] Are you still with me, if yes, please reply?
[Visitor] I am
[Amit] So what have you finally decided?
[Amit] You'll be charged 69.6p per MB if you use your Three mobile broadband services in ROI.
[Visitor] Not what I want, I have heard reports that THREE do a SIM where they do not charge roaming for internet only. But as that is not the case then I do not wish to proceed. Thanks
