[srsran-users] Identifying problems with SIM card

[Wellington Passos]

Hello everyone,

I'm having some trouble connecting UEs in general (smartphones of various
models and brands) to a LTE network, and I suspect the problem lies in the
SIM card.

 I would like to know if there is a way to attribute the cause of the
problem to the sim card without the need to buy and test other cards from
other brands.

I'm using MCR3516 Smart Card Reader, and the cards probably came with it.
When I program the cards with pysim, they are recognized as Open-cells
card. Anyways, I'm using the following commands to program my SIMs:

./pySim-prog.py -p 0 -n srsapn -a 88888888 --mcc 001 --mnc 01 --imsi
001010123456789 -s 8988211000000110000 --ki
00112233445566778899aabbccddeeff --opc 63bfa50ee6523365ff14c1f45f88737d

./pySim-prog.py -p 0 -n srsapn -a 88888888 --mcc 001 --mnc 01 --imsi
001010123456780 -s 8988211000000110000 --ki
00112233445566778899aabbccddeeff --opc 63bfa50ee6523365ff14c1f45f88737d

./pySim-prog.py -p 0 -n srsapn -a 88888888 --mcc 001 --mnc 01 --imsi
001010123456781 -s 8988211000000110000 --ki
82E9053A1882085FF2C020359938DAE9 --opc BFD5771AAF4F6728E9BC6EF2C2533BDB

My setup uses a USRP B210 as SDR in one laptop for enb and another laptop
for the epc. The result is the same if I run both on the same machine.

Attached are some files that I think might be important for someone willing
to help.
