Public Mobile

Welcome to the future, where the traditional SIM card is taking a digital leap. Enter the eSIM, a revolutionary innovation that's turning heads and changing the way we connect. eSIMs are here to bring more flexibility, convenience, and, quite frankly, a little bit of tech magic into our lives. Curious to know what an eSIM is and how it stacks up against the classic SIM card we’ve all come to know? Stick around as we dive into why Public Mobile is leading the charge in this digital evolution. It's the future of connection, served up on a virtual platter, and it's all about making your life easier.

What is an eSIM?

An eSIM is a digital SIM that allows you to access a cellular plan without having to insert a physical SIM card into your device. With Public Mobile, getting an eSIM is as simple as selecting it during the subscription setup process or switching over from a traditional SIM card. It provides instant activation, enhanced security, and the ability to have up to two phone numbers on select devices. That’s why Public Mobile is providing eSIMs for all eSIM-compatible phones.

Advantages of eSIM vs Physical SIM Card:

  • Quick and Easy Activation: eSIMs offer immediate activation within minutes, allowing a hassle-free setup.
  • Flexibility for International Travel: You can use a foreign carrier’s eSIM plan when travelling outside of Canada, making roaming more convenient.
  • Dual SIM Functionality: Depending on your device, eSIMs enable you to manage multiple phone numbers, making it easier to switch between personal and business lines.
  • Environmentally Friendly: eSIMs contribute to a greener planet by eliminating the need for plastic SIM cards.
  • Device Compatibility: Most new devices, including the iPhone XR and Samsung Galaxy S20, support eSIMs.

Managing Multiple Accounts Using eSIM:

With eSIM, managing multiple phone numbers on one device becomes effortless. You can label each line individually to differentiate between numbers, switch between eSIMs, and control which line accesses mobile data at any given time.

International Travel and Roaming:

Public Mobile's support for eSIMs enables you to switch to a foreign carrier's eSIM when travelling. Upon your return home, you can easily switch back to your local eSIM without any disruption to your Public Mobile subscription.

What Devices Support eSIM?

Most new phones, including popular models like the iPhone XR, Samsung Galaxy S20 and newer models, support eSIMs. Public Mobile provides a simple verification process to check your phone’s compatibility during the subscription setup. 

The Green Bonus – Environmentally Friendly!

By eliminating the need for plastic and reducing waste, eSIMs represent an environmentally responsible choice. Choosing an eSIM is not only a smart move for your mobile needs but also a thoughtful decision for our planet.

In Conclusion 

We hope this post has helped you understand the choices between a physical SIM card and an eSIM. Whether you like the quick and easy way of an eSIM or the familiar feel of a traditional SIM card, we want you to choose what's best for you. At Public Mobile, we're happy to offer both options for our new and existing customers. So whether you're trying something new or sticking with what you know, we've got you covered.

Great idea these blog posts but why are they posted in the lounge? Not only do they confuse the purpose of the lounge.....but how are people supposed to find them ? Lounge threads are unsearchable. There is zero chance a customer looking for info on these topics will find them using the search bar. The latest post no longer floats threads back up to the top and seriously who uses the filters? I know I don't. So all your time and effort producing these blog posts are all for they will slowly slip into the abyss never to be seen again except for the very curious or very bored members who like to dig around old posts. Put them in announcements at least....they could even be tagged if you put them there. They are a waste in the lounge.

I don't know about you but I think I need a shot of tequila about now?!! 🥃🍋🤪

Terrific!  Wondering how this works with travel to other countries?  How do I remove and add a SIM card?

Good Citizen / Bon Citoyen

Will be nice to be able to transfer e-sim to new phone. 

New in Town / Nouveau en Ville

If I purchase an eSIM may I switch back to a physical SIM card after that? 

Great Citizen / Super Citoyen

Tried it and love it. The switch to the PM E-Sim was quick and easy.  
Now I can use one phone with two separate carriers- how sweet is that.

@J_PM Thanks for the informative post.

Given we have the eSIM support, do we have any plans to support cellular smartwatches in near future? It would be great to know as I am currently debating whether I can stay with PM when the new smartwatches roll out in September.

Thanks again for the amazing support.

Better yet a 'One time purchase' e-SIM would also be suitable, so if you buy an e-SIM the first time, you are able to change it to any other device for free from the account you originally purchased e-SIM from.

Very informative post that was very much needed. Thank you! 👏🤝🙌

If you want to know how to install an e-SIM with an existing Account I have a step by step guide with screenshots here:

It is nice that both new and existing customers are able to purchase eSIM cards.  Hopefully, in the future, customers are able transfer eSIM cards from one phone to another.  At the present time, to transfer eSIM to a new phone, customers need to purchase a new eSIM for the  new phone.
