The USA SIM will work in the USA, including Hawaii, Guam, Puerto Rico and US Virgin Islands. The SIMs use a national US network. Please check the coverage before you depart as unfortunately we cannot issue a refund for poor reception. Coverage in the USA is generally very good for populated areas and main interstate highways but can be less reliable in remote and rural areas. The USA SIM will not connect in the UK but will automatically locate a signal in the USA on arrival. Please ensure you are using an unlocked tri-band or quad-band handset. For coverage details please use this link for the network map.

For a list of our most popular questions please see below or visit our online community.

  • Do I need a tri-band handset?

    Yes you do need tri-band or quad-band. In the USA, GSM operators use the GSM 850 or 1900 frequency. Therefore you need either a tri-band or a quad-band handset that has GSM 850 or 1900 capability otherwise your mobile handset will not work in the USA. Generally, tri-band handsets (GSM 900/1800/1900) are most suited to Europe with generally good coverage to work across the US. We usually recommend using a quad-band handset if possible (GSM 850/900/1800/1900).The 850/1900 MHz bands are used in the Americas and 900/1800 MHz bands are used in most other parts of the world. Compared to a tri-band phone supporting the 900/1800/1900 bands, a quad-band phone adds support for GSM 850 for full coverage in the Americas.

  • How much does it cost to call the SIM?

    If you provide contacts with your USA +001 number then local US based callers can call you at a low national rate but ask them to check with their provider for specific costs. Callers based in the UK, or outside of the USA, will pay an international rate to call your USA number.

  • How do I make a call from the USA?

    Dialing from the USA is straightforward – you simply dial +44 or 011 44 then drop the first zero of the UK number you are calling. The call will connect directly. Texts are sent in the same way as you do in the UK with a UK SIM, but the pre-fix is still required.

  • How does the SIM work?

    Firstly the SIM will only work in an unlocked handset. It connects to a local national US network and therefore you are able to avoid roaming charges that your normal UK network would apply. For full details please refer to the the user guide.

  • Validity

    To keep the SIM active you need to use it once every 30 days in the USA. The +1 US number is assigned when you activate the SIM. The service and +1 number will expire 30 days after date of last use. The PAYG credit balance on the USA SIM card will expire 30 days from date of last use. The calls and texts and data bundles will expire 30 days from date of purchase. The SIM service (ICCID) will fully expire 60 days from last use. Post-expiry, the SIM cannot be revived. The USA SIM is ideal for one off US trips or those who travel regularly to the USA and offers lowest rates possible. For annual trips we’d recommend our Global SIM as an option which has longer validity but rates are higher.

The USA SIM supports 3G and 4G data and data bundles can be added depending on your data needs. It will automatically connect to 4G, where available, or will revert to 3G. You need to be aware that streaming live video (e.g. FaceTime) or audio (e.g. Spotify or Skype) uses large amounts of data. As an example 100MB of mobile data enables you to:

Download 20 songs, or

• Download 15 mobile apps, or

• Watch 10 minutes of video, or

• Listen to 16 hrs on-line radio, or

• View 1000 web pages, or

• Send 200 emails with attachments

Data bundles are available via the 'top-up now tab' above to add as you require them and are valid for 30 days from date of purchase.

• 3G/4G mobile data bundles - 500MB $29.99 and 1GB $39.99, valid for 30 days from date of purchase. Using these data bundles achieves rates of as little as £0.03/MB in the USA compared to roaming rates in excess of £6.00/MB with some networks.

(Rates and credit top ups are currently only available in $USD but the network plans to introduce £GBP top ups and rates in the near future. Currency calculations reflect the prevailing exchange rates.
