The USA SIM will work in the USA, including Hawaii, Guam, Puerto Rico and US Virgin Islands. The SIM uses 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. Alternatively you can download the US SIM User Guide for the current version of the SIM.

  • 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. Please enquire if in doubt as unfortunately refunds cannot be provided if your handset is not compatible.

  • 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. You can receive calls and texts for free as long as you have a bundle plan active on your account.

  • How do I make a call from the USA?

    Dialling 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 user guide.

  • Validity

    The +1 US number is assigned when you activate the SIM and expires if your plan expires on 14 or 30 days, or if your balance expires. The service and +1 number will expire 14 or 30 days after date of last use (depending on initial bundle expiry). 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 14 or 30 days from date of purchase. The SIM service (ICCID) will fully expire 30 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 although rates are higher.

  • Topping-Up and call credit

    The SIM can be bought including credit for calls/texts (local and international) or with the unlimited (local call/texts/data) bundles. Bundles expire every 14 or 30 days but it’s simple to add credit or further bundles on-line. You may only add call credit if a call/text/data bundle is live on the account. Use your American Express, MasterCard or VISA card to add $30, $50, $100, $150 or $200 to your account via your on-line top up portal.
Top ups can be made in four easy ways:

    1. Online via a secure web site - Top up online now ($30.00).
    2. Dial 181 from your handset (FREE to dial, minimum top-up $30.00).
    3. Via customer service ($50.00). Dial 154
    4. By Auto Top-Up. Set up an automated facility online. (feature coming soon)

  • * Data bundles

    You can also take advantage of the pre-loaded call, text and data top up bundles which offer great value.

    • 'Starter' – (unlimited national calls/texts, 250MB 4G data, £2.00 international call credit) valid 14 days.
    • 'Unlimited' – (unlimited national calls/texts, unlimited data*, £8.00 international call credit) valid 30 days.
    • 'Unlimited Plus' – (unlimited national calls/texts, unlimited data**, £8.00 international call credit) valid 30 days.
    • To make international calls you will need to add $USD credit once the initial starter credit expires and you require to have an active bundle on the account.
    • Data bundles include 4G data - *1GB at 4G for ‘unlimited’, *2GB at 4G for ‘unlimited+’, then 3G speeds apply for ongoing use.
    • Fair usage policies may result in speeds throttling in the event of excessive usage.

    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 are for reference and reflect the prevailing exchange rates.

The USA SIM supports 4G data and bundles can be added depending on your voice and data needs. It will automatically connect to 4G (depending on bundle purchased), where available, or will revert to 3G depending on your location.

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 14-30 days from date of purchase.
