[DESCRIPTION]
在 Feature Phone 上，如果插 SIM 卡开机，有些 SIM 卡有提示信息，例如：“欢迎使用中国移动服务！”， 类似这样的提示信息是 SIM 卡上报的 display text, 手机是按照协议要求做显示。
display text 可分两类：
第一类：仅仅显示提示信息，不需要 user 确认；
第二类：必须要 User 输入或确认；
针对第一类不需要 user 确认的 display text 提示信息，在一些特殊项目上，如果不希望显示出来，请参考下面修改。
[SOLUTION]
因为 display text 是 SIM 卡上报的 SAT 命令，一定要回对应的 terminal response 给 SIM 卡，否则 SIM 卡就不能正常执行其他的 SAT 命令，可能出现的问题有：不能打电话。所以，如果不希望显示 display text,请参考下面修改两点。
为了安全，请不要使用原有的 timer id, 也就是不要使用 SAT_TIMER_CLEAR_DELAY ， 请自定义一个timer ID, 然后仅在这里使用自定义的 timer ID.
修改后的代码：
1. 添加函数：
void srv_sat_hide_display_text_timeout(void)
{
srv_sat_terminal_response_display_text(
sim_id,
SRV_SAT_TERMINAL_RES_CMD_PERFORMED_SUCCESSFULLY,
SRV_SAT_ADDITIONAL_RES_NO_SPECIFIC_CAUSE);
}
2. 修改函数 ：
注意代码中 #if 1 ......#endif
如果有问题，请提供 log, filter: MOD_L4C, MOD_COMMON_APP(group_3),MOD_SIM （ all class on ） ,MOD_FW.
