T-Mobile SIM Card R15 5G 4G LTE TMobile Triple Cut Nano Micro 3 in 1 Ultimate TMO Starter Pack with Simbros Simkey to Remove the sim Tray on Any Device!

I have read a few scary reviews about how these are old sim cards and how T-mobile is upgrading to a newer system and requires newer sim cards. What is scary is that T-mobile is indeed upgrading and has been for much of 2026. And so the reason for this review is to add a data point: I just activated this card on October 18, 2026. I had trouble activating online but when I called their phone line the activation was smooth. My phone is network locked to T-Mobile so if the card was anything less than a T-Mobile card (like a MetroPCS card trying to pass as T-Mobile) it would not have activated.

Great sim card next day delivery

If I could post zero stars I would. I got this sim card because T-Mobile required their brand of card. I put it in my phone and it locked up. I searched Google for a way to fix the phone. I called T-Mobile and they said to bring the phone in to a T-Mobile store. Not being able to drive at the time, my nephew took the phone to the store and they told me the card was out of date. The only way they could unlock my phone was to change my phone number. I had no choice but to change it. Of course then I had to go through the hassle of sending everyone texts, emails etc about the number change. I also changed my carrier to Visible which is a great carrier and very inexpensive.

It works fine my phone came out y he sim card

I was unable to use Sim card, I still have it in my pocket.

Easy communication to install, works great! I didn't think this was a real tmobile sim, i was wrong, works great! worked with tmobile to set it up, went thru flawlessly

I transferred my husband’s IPhone 17 back to an IPhone SE 3 rd generation with no problems. He is very happy to be back into IPhone SE,

Scamm scamm scamm Not connecting to metro s.e.r.v.i.c.e the sku #does not exist to adapt to n.e.t.w.o.r.k covered with metro. Not good at all {No=S.e.r.v.i.c.e} It is a scam!!! I need m.o.n.e.y back. If you need a sim just go directly to the metro store is only $10.56 that is less then this product. Buy a sim at direct store then you can ask for your personal plan. Terrible. No value for money no service.
