手机软件疑难杂症，来自美国的需求。

The sim cards are now set with the following information which is unique to each IMS subscriber.

P-CSCF: 172.16.15.134

DOMAIN: ims.mnc990.mcc311.3gppnetwork.org

IMPI: 311990000002886@ims.mnc990.mcc311.3gppnetwork.org

IMPU #1: tel:+18026921000
IMPU #2: sip:+18026921000@ims.mnc990.mcc311.3gppnetwork.org
IMPU #3: sip:311990000002886@ims.mnc990.mcc311.3gppnetwork.org

With regard to 911 the Samung phone use emergency as the APN so we have changed the core settings to use that APN instead of sos.
有谁知道上述信息是如何添加到软件里?请不吝赐教！

好像是与美国E911有关的，需要添加这部分信息到sim card里，但就是不知道在哪个界面。

修改APN即可
