Do all networks support e-SIMs?

Not all networks support e-SIMs – but they will do so in time when this technology becomes standard.

In the UK UKTell support e-SIMS in some capacity.


If you’re someone who needs multiple phone numbers or data plans, both e-SIMs and physical SIMs can come in handy. But which one should you go for?

Physical SIM cards are what we’ve all been using for years. You pop them into your phone, and they work just fine. They store your contacts and text messages, which is pretty neat.

Now, e-SIMs are a bit different. They don’t physically exist as a card. Instead, they’re built into your phone’s software. This means no more swapping cards when you want to change networks or travel. Plus, they free up space in your phone because they don’t take up any physical room.

But here’s the thing e-SIMs don’t directly store text messages or contacts. They rely on your phone’s internal storage for that. So, if you’re someone who still enjoys texting the old-fashioned way, this might be a drawback.

However, with most communication happening through apps like WhatsApp or Messenger these days, storing messages on your phone isn’t such a big deal anymore.

So, both options have their advantages. If you prefer having physical cards and keeping everything in one place, stick with the physical SIM. But if you like the idea of flexibility and not dealing with cards, consider giving e-SIMs a try.

And hey, if you’re looking to buy, you can get them from UkTell. and quick support available if you have any question.
