Sim Adapter - Nano To Micro, Nano To Full, Micro To Full Adapters, Made in Germany, Black

Probably one of the most expensive adapters at ~$8 but almost certainly the most reliable and durable. It's made in Germany of quality plastic to exacting dimensions, well packaged and has adapters for all three sizes of SDs. It's well worth spending an extra couple of dollars for a product that works well and doesn't break or get stuck in the SD slot.

Fairly clean once snapped off, fits card and phone well. I had to clean up one little bit of plastic to get a perfect fit around the card, but it's a good value anyway. Now I can swap cards among a few different phones.

I feel safe putting these in my phone. The extra dollars may not be worth it for everyone, but if you have an expensive phone, these are a good pick. There's no stupid tape on the lower side of each 'sadapter' to hold the card in place-- just a nub. This leads to a stable hold on the handful of cards I have (some cut, some natural) which, strangely enough, is less likely to release the SIM card prematurely and bend a phone's read pins compared to a normal adapter.

I was very wary of SIM adapters especially as badly fitting ones can damage spring loaded card slots, as has happened to me using a cut card, even cards cut by dedicated SIM cutters. After reading reviews on the best adapters to get if you really needed one, this type was highly recommended. The fit is as precise as it could possibly get, with very little noticeable protrusion of the card itself. Initially, I thought that the Nano to Micro adapter was a bad fit, but it took a very careful look to see just where and how precisely this was cut. No bulk or extra thickness and worked perfectly in my backup Blackberry Z30. I would recommend this product for sure.

I recently switched cellphones and my old phone had a NANO sim card while my new one only requires a micro sim card. Rather than have to take time to go the the carrier store and wait in line for service I just ordered this and it was at my home in 2 days..via Amazon Prime Shipping..it was fairly easy to snap my small card into the next size up( the one I needed) it holds very securely with no jamming when trying to take it out of the phone. Works perfectly! Never even needed to deal with my carrier and the phone works great! Would definitely recommend!

Why is it necessary to purchase three different sizes when you know the size that you need? It seems like a waste to purchase three things in order to use just one. Regardless, I did get this product to work. The SIM kept popping out of the holder but seems to stay in place once snapped into the Netgear LTE Modem I installed it into.

This worked great for me, but I will caution others that you need to pay close attention when you are inserting your micro sim into the plastic adapter. One sim I had snapped into place pretty well, the other sim I had to work on it quite a while to get it snapped in (guess it was trimmed a little wide). It is very important to do this as I can see where you could get your sim card stuck in the slot if you don't have it in the adapter cleanly. I expect that is where a lot of people get in trouble.

I purchased these because I wanted to be able to switch between phones without having to make a trip to the phone store every time. I looked at many different sim adapters and did a good bit of research before deciding on these. I decided on these adapters after reading a particularly terrifying article describing how badly a poorly made adapter could ruin your life/phone. They were the most highly recommended adapters. I couldn't agree more! A lot of the problems with other adapters has to do with how they hold, or don't hold the SIM card in place. Some have an adhesive strip, some have poor cutouts, others look like something you could have made from a cereal box. These are by far the best that I have found! The adapter is made of plastic and the cutouts are precise. You don't have to worry about your SIM card slipping out and damaging the slot in your phone because the card snaps (upside down) into a perfectly cut, sturdy ledge and you can easily insert/remove the sim in your device. This product is very well made and while I don't foresee it breaking, if I ever have the need I will definitely repurchase and absolutely recommend it to anyone!
