如何通过SIM_IO从SIM卡读取MSISDN? [英] How to read MSISDN from sim card by SIM_IO?

问题描述

我需要在android中阅读MSISDN，但是我们必须使用.c来完成它.我打开一个套接字，将 RIL_REQUEST_SIM_IO 发送给ril.这是日志.

I need to read MSISDN in android, but we must use .c to finish it. I open a socket to send RIL_REQUEST_SIM_IO to ril. Here is the log.

D/RILC    (  106): [0004]> SIM_IO (cmd=0xB2,efid=0x6F40,path=3F007F10,1,4,30,(null),pin2=(null),aid=(null))
...
D/RILC    (  106): [0004]< SIM_IO {sw1=0x90,sw2=0x0,ffffffffffffffffffffffffffff0891684125205260f5ffffffffff}

我是否使用了正确的参数(P1 = 1，P2 = 4，P3 = 30)?

Did I use the right parameters (P1 = 1, P2 = 4, P3 = 30)?

如何通过响应获取手机号码?

And how can I get the mobile phone number by response?

谢谢！☺

推荐答案

您对此有何困惑?您想知道您告诉卡片的内容吗?所有这些信息均在ISO 7816-4和其他一些规范中提供，但这是您执行操作的详细信息:

What is your confusion here? You wanted to know what you told the card? All this information is in ISO 7816-4 and a few other specs, but here's the details of what you did:

您已向SIM卡发送了一条读取记录命令(0xB2)您要求输入路径:

You sent a read record command to the SIM (0xB2) You asked for the Path:

3F00 -> (MF)
7F10 -> (DF_TELECOMM)
6F40 -> (MSISDN)

您设置参数:

P1 (record)                   = 1  (record 1)
P2 (reference control)        = 4  (this mean use record number set in P1)
P3 (Le meaning bytes to read) = 30 (bytes)

您获得了成功(SW代表状态字，您得到SW1/SW2 = 0x9000表示成功)和数据(0xffffffffffffffffffffffffffffff0891684125205260f5ffffffffff)

and you got back success (SW stands for status word, you got SW1/SW2 = 0x9000 which means success) and the data (0xffffffffffffffffffffffffffff0891684125205260f5ffffffffff)

在解析时结帐 E.164 您的MSISDN.
