eSIM is here 🎉
You’ve been asking, and we’ve been listening. We’re excited to let you know that eSIM is now available for existing SMARTY customers🙌
We’re starting things off with a soft launch, so right now you’ll only see the option if you’re an existing customer and you go through the SIM replacement journey. That means if your phone supports eSIM and you want to switch from your physical SIM, you’re good to go.
Wait, what’s an eSIM?
An eSIM (which stands for embedded SIM) is a small chip that’s built directly into your phone or device. Instead of inserting a physical SIM card, your mobile plan can be downloaded straight onto the eSIM.
Think of it like streaming a song instead of popping in a CD, it’s all digital, and it’s all seamless.
How to make the switch
Just log into your SMARTY account, head to Account settings > Manage plan > Replace SIM, and choose to replace your current SIM with an eSIM. Follow the remaining steps and you’ll be up and running in no time.
We’re rolling this out carefully to keep things smooth, but more eSIM goodness is on the way 👀

I am going to Australia and New Zealand in January. If I swap to a SMARTY eSIM will I be able to buy a Aus/NZ regional package over there for one month and use my SMARTY eSIM? Or do I still need to buy the (expensive) SMARTY data/call/message package for those countries?
Why is the Internet so weak and bad? Is there a solution to the problem?
Hello!
I currently have an iPhone 12 with SIM card.
if I travel and buy a new phone (eSIM only) abroad, can I set it up smarty’s esim there, and toss the old phone or do I have to be in the uk to set it up?
thanks!

Gabriel_2086494 Firstly, you will need to be sure that you buy a version that will work with UK network frequencies.
Secondly, as I understand it, you will need a code to make the esim work and it should therefore be possible to move the sim from one phone to another once you have the code.
You will also need to ensure that you make that esim the priority use sim o your phone.
The activation code like the QRcode are one time things
It may be that iPhones support an eSIM transfer process but the default will be to request a new eSIM
I know from experience that can go wrong - and even on chat it took some effort to get to an activation code at the end of a long chat session
Moving a SIM to a new phone is easy with physical - I'm not looking forward to having to go through that again for a new phone
eSIM is likely going to be a more frequent topic now so its worth researching it.
I'm also on Android and don't have the option to swap my physical SIM for an eSIM in the app, although I can see that option on the web page so thank you to who posted that.
I have a Samsung S25 Ultra and Samsung watch ultra, so I would like to know how to get the eSIM working in the watch. In the Three shop they said it would possible with them (although they made it sound like a second contract). Ideally I would just like to swap the eSIM between the phone and the watch, I don't need them both simultaneously active. Anyone know if that is likely to be possible?
ChrisM Unfortunately, not currently possible with Smarty: https://help.smarty.co.uk/en/articles/10131368-using-a-smartwatch-with-smarty-what-you-need-to-know
If I want to transfer my number to another phone how do you transfer an eSIM?
Will the e-sim work with other networks worldwide.
PhilipW_2272353 It will work the same as a physical sim. You will be able to roam in EU countries using your Smarty plan. You will need add-on credit to roam in other countries - price as per the Smarty Price Guide.
There is no replace SIM option for me within the Smarty app dashboard. Account settings and Manage plan are 2 separate buttons and neither contain a replace SIM option. What am I missing?
Thank you. That worked. I wonder why Smarty haven't implemented that feature within the app?
Excellent! I've just swapped mine over. Seamless and super quick.
Any news on when/if Smartwatches will be supported. Would love to add my Samsung Ultra to my eSIM connection.PaulWil_2300509 That's good to know!
Now, now, you're being a bit impatient aren't you!? 😥 The wheels of Smarty grind exceedingly slowly - look how long it took to get this far 💤
Hi. I’ve activated eSIM on iPhone 16 but physical sim still showing as primary. Cannot make calls or send texts. Please help
DavidSm_1800216 Don't you need to remove the physical sim or at least turn it off in the settings?
I haven't done this with smarty yet, but have used esims alongside the physical sim and normally need to choose which one I want to use.
Yes that is the solution thank you otherwise every time you phone you have to chose the sim
