Customer Ratings & Reviews

Good price i am just not using this product right now

Just what i needed to help me set up a second phone.

It works. I was already a T-Mobile customer. When I changed phones, I needed to change to a smaller SIM card. After I called the customer service and provided a little personal info, it was set up. Less than 10 min.

I bought anew phone but my sim was too large for slot. I then purchased the starter kit from best buy and via live chat with TMobile I was up and talking in 30 minutes. One of the easiest phone swaps I have ever done. Thank you best buy and T mobile for the painless transition.

I am a very old Customer of TMobile. The process of getting this for my friend who travelled to US was very simple and convenient at BestBuy. The plans offered were also cheep. I would recommend this.

I bought this because I forgot to take my old sim card still this is and excellent product it come is any size you might need for you cellphone and it only cost me less than 5 dollars if I had bought it at T-mobil it would had cost me around 10-15 dollars.

If you're looking for the best t-mobile sim card, look no where else! This sim card will get you access to the t-mobile network like no other sim card will. I definitely recommend having a t-mobile sim card if you're wanting to get onto the t-mobile network.

Got starter kit but didn't need it at the end since my old sim card worked

I bought this kit to get a second line from T Mobile. I was happily surprised with the fact that it brings a whole set of SIM adapters that are the best I´ve ever tried. Even if you are not needing a new SIM card, the adapters are worth the whole kit.

Got an unlock phone for my mom and wanted a easy simple solution for her. Representative told me about the T-mobile activation sim and yes it was very easy to activate and my mom is happy

Went to store TM omg what confusion I continue to shop at BB

It was a little bit hard to find this item in the store, but with the help of a nice employee I was able to locate it. I am not sure if they will be carrying these any longer, but I am really glad they had some left because it is exactly what I needed.

Does not work out of the box, you have to take it to a T-MOBILE store or to someone in the store.. Packaging is misleading and best buy in store employees have zero feedback on these kinda items.. Waste of time and money.

Nothing special to highlight. It serves the purpose Thanks,

Great flexibility with all the adapters. Really liked the packaging! Fast activation. All necessary information included. Was able to use phone minutes after activating phone.

the sim card works as advertised but t-mobile customer service is a disaster. keep getting different answers from the phone rep and the store clerk. called the 1-800 number to activate the sim card only to be told we shuold do it in store. went to a physical store only to find out it costs 20 bucks to activate the sim card in store so it's better to activate it over the phone... very frustrating process. in the end, still unsure if i activated it correctly since I had to mail the card to my grandma oversea ... apparently she had trouble using the phone once she landed in LA...

I was given a chip so I did not use this started kit.

Make sure you go through all details on the card...

I BOUGHT THESE TO ADAPT MY SONS PHONE FOR USE ON CRICKET!! I KNOW THESE ARE TMOBILE BUT THE ADAPTERS ARE THE SAME!!! THEY WORK BUT IF YOU HAVE A PROBLEM GETTING THEM OUT OF YOUR PHONE THEY BREAK ON THE WAY OUT!!! THEY WORK BUT ARE NOT TO STURDY!

What can i say it just works and if your in T-Mo coverage its a no brainer. Best Mobile network (when you have data coverage). And FYI by the end of 2015 they should have covered most of there 2G network over to 4g/LTE... ;-)
