What is an eSIM?
So we all know what a SIM card is, a tiny chip that slots into your phone that you can never find the tool to pop out, well an eSIM is just a tiny embedded version of that in your phone. With an eSIM you’ll effectively have two SIM cards in your phone; one physical, and a second embedded.
Apple prefers the term Dual Sim
How do you use an eSIM?
So unlike Another Number, an eSIM will be a second number embedded into your phone and not run through an app, the service will require a contract and compatible device. Currently, in the UK you can get an eSIM from EE, O2, Virgin Media or Vodafone.
Beware that not all phones support dual-SIM connectivity, meaning you cannot have two numbers active at the same time.
What device do you need for an eSim?
So what phone will you need to run an eSIM from? The following are eSIM compatible in the UK:
iPhone XS Max, XS, XR, 11/12/13, 11/12/13 Pro, 11/12/13 Pro Max and SE 2020
Samsung Galaxy S20 4G, S20 5G, S20 5G Plus, S20 Ultra 5G
Google Pixel 3/4/5/6 and 3/4/5/6 XL
What is the eSIM Experience?
So, now we’ve discussed the requirements to get an eSIM, how do you get one? Well, you generally need to get a new plastic SIM and then convert it to an eSIM, a bit of time with mobile network customer support 🤔…
What is an eSIM like to use? Well, on an Apple device it works flawlessly through iOS but its use is integrated into the same workflow as your primary number but marked/tagged – i.e. the second number is flagged in iMessage & your call history etc.
An eSIM is ideal for combining two networks on one device, for example, EE at home and O2 in the office and therefore offers increased coverage options. However beware that some dual SIM phones like the Pixel 3 & XL can only use one number at a time, therefore you won’t have two phone numbers at the same time!
What is the price of an eSIM💰?
The price of an eSIM varies depending on the data you need. However, you will very likely need a second mobile contract for 24 months.
