Customer Ratings & Reviews

Worked for my unlocked phone after acitvating online. Did not have to call T-Mobile and wait on hold. I chose their $3/mo for their Pay as you Go plan. No contract and great for an emergency phone!

Easy way to activate a T-Mobile prepaid plan. Comes with $40 airtime included to activate on a monthly $40 plan. Activated in store with ease. It also comes with sim adapters to fit most unlocked phones.

The price is excellent but the actual set-up is taking very long and while T-Mobile will do the set-up in their stores best buy does not.

I purchased a prepaid Sim for the $30 5gb limited voice plan. Packaging is cool and I had it in the phone and activated in a few minutes. Simple process and inexpensive.

Best services ever I've had through any cell phone provider. I've never had any drop calls from T-Mobile and I have service no matter where I travel with my company.

I bought this to Start my phone with T-Mobile. Best Buy offers a great value for this product at Christmas time as well.

This inexpensive SIM card works for both T-Mobile prepaid AND T-Mobile post-paid. Much less expensive than the $15 SIM cards they sell at the T-Mobile stores.

Tmobile has gerat prepaid plans and great signal, I don't know why BestBuy is no longer selling Tmobile stuff but its still the best cell service out there.

Purchased this when switching from another carrier, works great (and the package is fun too, it have a special paper based packaging that is easy to open).

Good value for what I get. Tax and government fee are additional.

Can avoid activation fees if you get the kit and do it online or over the phone. You could press a counter agent and avoid the activation fee as well

T- mobile gives a good connection in NYC Reaching their customerservice is simple .and they are very helpfull. Good price/performance ratio.

I activated this and my phone number was transferred without issues. Phone automatically configured to the TMobile network. Would buy it again.

I thought I could use the SIM card to activate a monthly (post-paid) but found by calling T-mobile that I could not. When I tried to switch to post-paid. T-mobile rep ran my credit and said I would need to provide deposit. I've had cell phones from Verizon, Sprint, and AT&T and never had to provide deposit. I've had cell phones since 1996, never had to pay deposit. My current credit score is excellent so I don't get why T-mobile would require a deposit. Anyways, I don't think I will be dealing with them in the future.

If you need a Nano sim for your device you won't have an issue, but if you need to use the included adapters you are out of luck. The plastic that the adapters are constructed of are very flimsy and the nano comes out of the adapters and gets stuck in some devices and you can't get it out. Also, the adapters it self gets stuck, I ruined a device trying to get the adapter and the nano out. My suggestion is to go to a T-Mobile location and purchase a Universal sim card if you need either a micro or standard sim card.

Perfect deal and awesome service service from the person in blue shirt. T-mobile seems to work better than Verizon at times.

When I bought a Blu to hold a UK SIM I was dismayed to learn the card was a micro was too small but the starter kit solved that problem!

Got a new sim card and activated on a new plan. Just followed the instructions and I had my new sim activated within minutes!

Wished it was cheaper. Got this for family coming from overseas. Worked great and was the cheapest of the 4 major phone operators

I purchased this for the reason of using the SIM card adapter to go from a NANO to a Micro. The adapter fit in the slot but the phone did not recognize the SIM card.
