Hi …
In your wiki you have referred for this sim cards http://shop.sysmocom.de/products/sysmousim-sjs1-4ff. does this sim card comes with some configuration ?
I have a bunch of blank SIM card and a card reader , is that sufficient or should I used the one you referred?

Thanks

If your SIM card is writable SIM, we think it’s enough to program your SIM card yourself.
