Physical SIM card and eSIM in the UK

UK SIM cards can be categorized into 2 main types based on their forms:

  • Physical SIM card: a SIM in the physical form, can be inserted or removed physically.
  • eSIM: a virtual SIM/ digital SIM which is built-in to your mobile phone.

Each type is also further classified by function:

  • Data-only SIM (no phone number): used for data usage (Internet browsing, map navigation, access to chat apps like WhatsApp, Telegram), unable to make phone calls or send text messages. 
  • Data + voice + text SIM (phone number): best for travelers who want to have an Internet connection to send messages, make phone calls, navigate maps, browse the web, etc.

Let’s look further into the two types: physical prepaid SIM card and prepaid tourist eSIM in the UK:

1. Prepaid physical SIM card in the UK

A prepaid physical UK SIM card is a SIM card that exists in a tangible form. To activate it, you need to insert it into a designated slot of your phone or remove it from your phone. Tourists traveling to the UK can choose a data-only SIM or data + voice + text SIM depending on their priorities and needs.

2. Prepaid Tourist UK eSIM

eSIM is a chip that is built-in to your mobile phone. Unlike a physical SIM card, you do not need to insert or remove a physical SIM when switching carriers or packages. eSIM can be bought and activated online and also has two sorts (data-only plan and data + voice + text plan). To use UK eSIM, you will need an eSIM-compatible cell phone.
