I bought this to adapt my micro sim from my phone to an old tablet I had laying around to reboot it and get it back online. Unfortunately the way these adapter chips are set up the plastic that holds it in place so you can slide it into your device properly is a little too flimsy. It kept flexing and popping my sim card out inherently getting it stuck inside the device sim slot. I had to fish my sim out twice by sheer luck and when I tried it a third time had to disassemble my tablet to get my sim card back out. You kind of get what you pay for on this product. flimsy plastic material that doesn't securely adapt the micro sim Great concept just needs a change in material to make it a little more sturdy.
A pretty straightforward product, just fit your smaller SIM card into the larger adapter and it works as it should. The adapters are cut well, and it's nice that the package comes with all three sizes and a little tool to pop open any SIM tray.
That said, it has a significant flaw with the card not staying in place. There's nothing to secure it, so when I went to slide it in to place, the SIM slipped out and got stuck in the slot and nearly ruined the connecting pins. I ended up using a tiny dab of glue to hold the card in place. It would be perfect if it had some kind of snap-in-place fit, or if the clear plastic backing had some mild adhesive on it.
If I weren't so lucky I would have lost my phone. I don't want to recommend it, but for some people this type of product will be the best option, and with a fairly simple tweak it is workable.
Product is packaged using an adhesive, and will stick to the inside of your sim card slot––which may be irreversible if necessary precautions aren't taken. I suggest using a product like Goo Gone to remove traces of the adhesive before using the adaptors. Works well otherwise.
So these sim card adapters are right for the job. They are high quality. Although, the biggest problem that happened is that the inside of it has sticky residue that is difficult to clean. So, if you are looking to use this with another sim card after a month or so you may have to get a new card. The sticky residue which is a left over from their cheap packaging make this product good for one use only. If you wanted to reuse it another time seems unlikely until they find a better way to package it other than tape that melts to the inside of it.
It didn't really fit my sim card correctly. It could just be made for a different sim card, but my sim card was too fat to fit all the way in. We managed to get it into the sim slot, but the sim card fell out of the sim card holder a lot.
Looks great. Doesn't hold nano sim tightly. Falls right out the bottom. If I invert sdcard then falls out. Very difficult, nearly jammed sim a couple times. Was Amazon choice so had higher expectations.
The card fits but it does take some maneuvering. The only real thing that is a hassle is that the top is a clear smooth plastic and does not pull out of the sim tray easily At All. I had to score the clear side to provide grip.
