t-mobile standalone 5g sim card

Will I be able to use 5G if I am on a 4G handset with a 5G SIM card? No. You will need a 5G-capable handset to enjoy 5G . However, you will be able to continue browsing data seamlessly with 4G.

Changing your SIM card will help to ensure you get more 5G in more places when using a compatible device , such as indoors and in rural locations, and will make sure you’re ready to take advantage of future network enhancement.

A SIM card that was activated in a 4G device will still work with a 5G device , but you may have trouble connecting to the 5G network. Check with your carrier if you’re not seeing the little 5G logo pop up on your screen and you think you should be.
