相關(guān)說明

1、不同平臺的Modem配置TS.25或許會存在差異，比如6835芯片的配置路徑在modem_t_6835 / mcu/custom/service/plmn/TS25。

2、TS25文件用于顯示運營商名稱，較新的平臺機(jī)制（帶MIPC的平臺）才移到Modem維護(hù)的。沒有TS.25時，會在Telephony AP側(cè)配置，spn-conf.xml中。

定制方案

無法修改網(wǎng)絡(luò)上報的信息，客制化只能在Telphony FW中配置運營商名稱期望值。

針對平臺定義的運營商名稱，修改在spn-conf.xml，具體看mk編譯生效文件的路徑，可能用：

• /device/mediatek/system/common/
• /device/mediatek/common/

<spnOverride numeric="72207" spn="Movistar"/>
<spnOverride numeric="722070" spn="Movistar"/>
