Guay Mobile Plans

If you're looking for an affordable way to use your cellphone when travelling in Spain, you can get a Guay Mobile eSIM from only US$4.50 (approximately €4.20) for 7 days usage.

To get a Guay Mobile eSIM, you'll need to have an eSIM-compatible device such as the iPhone 11, Galaxy S20, Pixel 3 or later devices. You can then order your Guay Mobile eSIM through the Airalo app with instant delivery direct to your phone. There's no need to queue at the airport or to register the Guay Mobile eSIM with your ID, saving you lots of time.

Once you've ordered your Guay Mobile eSIM, it will only activate when your cellphone actually connects to a supported network in Spain. This means the validity period will only begin when you actually land in Spain and turn your cellphone on.

Your Guay Mobile eSIM works with the dual-SIM function on most modern smartphones. This means you can use your regular SIM card alongside the Guay Mobile eSIM (e.g. to receive incoming phone calls and text messages on your normal phone number).

Alternatives to Guay Mobile

The main disadvantage of Guay Mobile is the fact you're getting a data-only service on the eSIM. You will not get a local phone number in Spain when you're using the Guay Mobile eSIM in your phone.

If you'd like to call or text whilst you're travelling in Spain, you'll need to use your normal SIM card instead (on which international roaming fees may apply). Alternatively, you can side-step these charges by making your calls through WhatsApp or other similar apps.

If you're looking for a more fully featured SIM card with a local phone number in Spain (starting with +34), you could consider getting a regular prepaid SIM card upon arrival instead. This will involve some additional hassle (e.g. queuing up at the airport to get your SIM card, a registration process for the SIM card, etc) but it can be preferable and better suited for longer-term use in Spain.

Guay Mobile Coverage

If you're using a Guay Mobile eSIM, you'll have access to 4G mobile coverage in Spain. This is provided by the following partner networks:

There's no international roaming available on a Guay Mobile eSIM. Therefore, you won't be able to use it outside of Spain. If you're planning to visit multiple countries on your trip, you may need to get a separate eSIM for the other countries you visit.

Other Airalo eSIMs

Airalo's Guay Mobile eSIM can only be used in Spain.

If you're planning to visit multiple countries on your trip, you could consider getting a Eurolink or Discover eSIM. These eSIM plans will work in Spain, as well as a number of other countries.

However, it adds the ability for you to make and recieve phone calls and SMS text messages on your eSIM. You'll be assigned a +43 phone number (based in Austria) to use for calling and texting.

  • Hi Ken
    Love this site!
    I’m off to South Africa in Feb 24 and I have a EE contract, they however do not cover that Country in their Data Roaming, what is the best way I can use my phone over there please?
    Get a sim when I land or do you know any other deals

  • I just arrived in the USA and Airalo is amazing – I bought the the sim on the airport wifi, and had it fully set up and on the network before I got to LAX baggage claim! So easy, no paperwork, didn’t need to find a shop/kiosk, queue, open up the phone or any of that nonsense. Also with dual sim capability I’m still able to use my British number for receiving sms/iMessage.

    It’s good coverage too, and it automatically swaps between AT&T or T-Mobile depending on the area. I’d highly recommend it and look forward to using it in other places in the future.
