Currently, within the UK, local operators allow the use of virtual SIM cards as long as you have a compatible phone. Being a tourist, buying this service locally can be demanding, so we recommend using virtual stores to get an digital SIM card.

Some of the most critical operators in the country are Vodafone, O2, and Three. If the online store offers you coverage from any of these, you will be assured of service during your adventure.

eSIM United Kingdom card need-to-know information:

As virtual SIM cards are completely unseeable, they are still new technology, which is why some cellular devices are not yet compatible with them, but so that you don’t have any problems when you travel to the UK. Here is a list of things you should have in mind before buying an eSIM card.

• First, make sure that your cellphone is compatible with eSIMs. In addition, also check with the operator or provider with which you will connect on your journey.
• You must have an email address in order to register and receive your digital SIM card.
• To activate your eSIM, you must have an internet connection, as your profile is downloaded from the carrier’s servers. For this reason, we recommend you do it before your trip or if you are in the UK from a secure network.
• Some providers will require you to install their App to download the eSIM.

If your smartphone does not support this type of SIM cards, we recommend purchasing a traditional physical SIM card.
