The test case in Chinese
前提条件：无
测试步骤：1.插入联通4G卡
2.插入移动4G卡
预期结果：
1.中国联通2G、中国联通3G、中国联通4G，中国移动2G\3G\4G为网络禁用
2.可用网络列表中会显示：中国移动2G、中国移动3G、中国移动4G，中国联通网络为禁用网络
实际结果：
1.显示：CHN-UNICOM
2.显示：CMCC/china telecom

1.We need to translate carrier names into Simplified Chinese.
CMCC => 中国移动
China Unicom => 中国联通
China telecom => 中国电信

2.If a CMCC sim inserted on ubuntu phone, go to carrier page and wait a while for searching
actual => CMCC is selected automatically, China telecom is listed as option for manual select

If a CMCC sim inserted on iphone, go to carrier page and wait a while for searching
actual => CMCC, China Unicom and China telecom are listed as options for manual select

Issue: China Unicom isn't listed in the carrier list on ubuntu phone (refer to pic2)

3.If a China Unicom sim inserted on ubuntu phone, go to carrier page and wait a while for searching
actual => China Unicom is selected automatically, no other options for manual select
If a China Unicom sim inserted on iphone, go to carrier page and wait a while for searching
actual => China Unicom and CMCC are listed as options for manual select

Issue: Other carriers cannot be searched out on ubuntu phone if CMCC sim inserted (refer to pic3)

CTA requires at least one more carrier can be searched and shown in the list that user can select manually.

So if we can fix #1 and #3, then we are good for CTA certification.
