相关说明
1、不同平台的Modem配置TS.25或许会存在差异，比如6835芯片的配置路径在modem_t_6835 / mcu/custom/service/plmn/TS25。
2、TS25文件用于显示运营商名称，较新的平台机制（带MIPC的平台）才移到Modem维护的。没有TS.25时，会在Telephony AP侧配置，spn-conf.xml中。
定制方案
无法修改网络上报的信息，客制化只能在Telphony FW中配置运营商名称期望值。
针对平台定义的运营商名称，修改在spn-conf.xml，具体看mk编译生效文件的路径，可能用：
- /device/mediatek/system/common/
- /device/mediatek/common/
<spnOverride numeric="72207" spn="Movistar"/>
<spnOverride numeric="722070" spn="Movistar"/>
