Hi ​@Cathaypacific,

The USA is in iD Mobile's Roam Beyond zone, which means your UK allowance won't work there. It's also important to note that the available add-ons are data-only.

The add-ons work well for using maps, browsing the internet and apps while you're away, but they don't include calls or texts. Any standard calls or SMS will be charged separately at our out-of-plan roaming rates.

We've had many customers successfully use our Roam Beyond add-ons in the USA. To help ensure the best possible service, we'd recommend manually connecting to one of our roaming partners if needed:

• AT&T
• T-Mobile
• Commnet Wireless
• Verizon

How the Roam Beyond add-ons work:

• You can purchase a data-only bundle via the iD Mobile app or your online account.
• The add-on starts immediately upon purchase and lasts for a fixed duration.
• Once it expires, you'll need to buy another add-on or you'll be charged standard roaming rates (if your bill cap allows this).
• Your regular UK allowance (minutes and texts) isn't included while in the USA.

How to check if you have a bill cap in place:

• To view or change your bill cap, log in to the iD Mobile app or your online account, go to the Bills section, and select Manage bill cap.
• You can adjust this using the slider or by entering an amount (between £0 and up to £75.00, depending on your account type).

Add-on options:

Standard roaming charges (without an add-on):
 
The table below displays how much you’ll be charged for any minutes, texts or data that you use.

* 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.

Tip:
Depending on how long you’re staying, it may be more cost-effective to get a local SIM in USA, since the bundles last a maximum of 10 days, you may need to purchase multiple add-ons, which can become expensive.
