## Description

desertcart.com: Gialer 100PCS Writable Programmable SIM Card 4G LTE WCDMA GSM Nano Micro 2FF 3FF 4FF Blank USIM Card for Telecom Operator (100pcs) : Everything Else

Review: As described. Used in a Open5Gs core (with an LTE small cell) - 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.
Review: Programmable SIM/USIM for Osmocom, but doesn't work with pySIM - 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.
