Failed to activate 4G data Internet access

[h1k0n]

你好! 我测试发现4G无法上网。镜像由最新的提交构建，运营商是中国联通。 弹框要求输入APN密码： 这是ModemManager和NetworkManager日志：

[chuangzhu]

Are there any other APNs in the "Acess Point Names" setting other than "Default (3gnet)"? There should be a "联通彩信 (3gwap)"

[h1k0n]

Yes, I saw it. I chose 3gwap with username and password empty and immediately prompted connection failed. How should I configure it?

[chuangzhu]

Weird. It works on my oneplus-enchilada. What's your phone model, nixpkgs and mobile-nixos revision? I'm using b211b392b8486ee79df6cdfb1157ad2133427a29 (2024/5/7) for nixpkgs and 5455e4455b231218f6198b39383a0ad4c1d6638e (2024/4/14) for mobile-nixos. The kernel version is 6.4.0

I use these configurations and after flashing into my phone, it still prompts connection failed.
