I have observed that value for this properties varies in some API level. I have tried to address this issue.

You can use following command to change the value on API 26:

1. adb shell
2. su
3. setprop gsm.operator.numeric 280701

Note: Some emulators require restart.

On some emulators the property can be different name

You can find the property name as follows:

1. adb shell
2. getprop

It will give you data similar to following:

...
[dalvik.vm.lockprof.threshold]: [500]
[dalvik.vm.stack-trace-file]: [/data/anr/traces.txt]
[dalvik.vm.usejit]: [true]
[dalvik.vm.usejitprofiles]: [true]
[debug.atrace.tags.enableflags]: [0]
[debug.force_rtl]: [0]
[dev.bootcomplete]: [1]
[drm.service.enabled]: [true]
[gsm.current.phone-type]: [1]
[gsm.defaultpdpcontext.active]: [true]
[gsm.network.type]: [LTE]
[gsm.nitz.time]: [1524141151210]
[gsm.operator.alpha]: [Android]
[gsm.operator.iso-country]: [us]
[gsm.operator.isroaming]: [false]
[gsm.operator.numeric]: [310260]
[gsm.sim.operator.alpha]: [Android]
[gsm.sim.operator.iso-country]: [us]
[gsm.sim.operator.numeric]: [310260]
[gsm.sim.state]: [READY]
[gsm.version.baseband]: [1.0.0.0]
[gsm.version.ril-impl]: [android reference-ril 1.0]
[hwservicemanager.ready]: [true]
[init.svc.adbd]: [running]
[init.svc.audio-hal-2-0]: [running]
[init.svc.audioserver]: [running]
[init.svc.bootanim]: [stopped]
[init.svc.camera-provider-2-4]: [running]
[init.svc.cameraserver]: [running]
...

Search for numeric by copying the output in text file. Get the property name and use setprop

You can also use getProp to verify whether the value has been changed.
