eSIM works, here’s how to activate

You are an amazing person. I did this via Employee Team of Experts Chat on the T-Mobile app. I simply told the rep that I wanted to do a SIM swap and that I only had the EID available. He then asked me to confirm what I wanted, and I said the EID will populate a SIM number once it’s entered. He said that we could give it a try, and sent the PIN to my primary line. All in all, it took less than five minutes.

Now I have both of my T-Mobile numbers on one phone. SWEET!

One thing I will mention, in case it hasn’t been already, is that a store can probably do this as well. Since when we enter the EID number of a device, it populates a SIM number...
