100PCS Writable Programmable SIM Card 4G LTE WCDMA GSM Nano Micro 2FF 3FF 4FF Blank USIM Card for Telecom Operator (100pcs)

Item as described: ten of the cards, all working with the software GRSIMWrite it is meant to be paired with. Used to connect handsets to a small cell CBRS network.

It's a programmable SIM card, comes with (common) ADM key, suitable for connecting to test networks that you manage yourself. Good example is SDR based osmocom or srslte. It comes completely empty, so you will need to generate and program id, keys and other values. Only way to program it is by using it's own application "GRSIMWrite" for windows/macos. It's not supported by pySIM tools. This is to be expected, as sim card programming is not a standard. It would be nice if vendor would add support of this card type to pySIM.

Good value

The Gialer LTE card program suit was everything it needed to be for the more experienced cellular programming engineers who are familiar with the SIM card programming platforms. It was lightweight, has every component as stated in the kit, but was a little too complex for the less experienced programmers. I highly recommend the Gialer suit if you are in the industry and know how to program LTE/4G /5G sims cards. The shipper was excellent with on top communications.

I ordered this product expecting 10 pcs. but when I opened the box there were 6 total shells, and only 2 actual sims. This was nothing like the description.

worked great to make a softbank sim for a old flip phone, used with a generic read/writer.

I got test devices to connect to a system running srsRAN with a bladeRF software defined radio. I hope this review helps anyone else looking for cheaper SIM's to use with this kind of setup.

It was interesting and easy to use

This product is waste of money the don't provide software and when you download from website won't able to clone the sim I have searched in Google darkweb but I can't find any software that can clone the sim I have wasted money 18000Rs
