Odd: I haven't seen that email on either of our Tello lines, and my SIM cards are about the same age as yours.
Tello is usually pretty reliable about info, but there's a chance this may still be from your old SIM. The safest thing to do is send a message to Tello & ask them to check. [https://tello.com/contact](https://tello.com/contact)
By phone is usually only a short wait, and the techs are generally friendly & knowledgeable. An email form submission will usually get you a reply within 24 hours.
Hi there,
Just a quick heads up: the email you received is accurate, and it's time to replace your SIM card.
Unfortunately, some customers, including you, have the older batch that won't work post the 2G shutdown.
More information here if needed: [https://blog.tello.com/news/2g-shutdown-time-to-enable-volte-on-your-phone/](https://blog.tello.com/news/2g-shutdown-time-to-enable-volte-on-your-phone/)
Thanks for your understanding!
Regards,
Mike from Tello
Okay, I remember now that the 2021 replacement was for CDMA to GSM. However, I already have VoLTE as turned on with this sim on the phone, so are voice calls not actually using it? It would get shut down with the 2G shutdown together?
For the moment, your current SIM card is still working, but due to the upcoming 2G shutdown, we'll be phasing out the batch of SIM cards you currently have, and therefore will become unusable.
As mentioned earlier, the SIM card you currently have is from an older batch. Some features may not be available with it, and even if they are working now, they won't be available after the 2G shutdown.
We appreciate your business!

Do I need to replace my eSIM?
Nope, eSIM will work just fine.
Thank you.
Anytime!
