係喎. 我都知香港有band1,
佢個外國網都唔知香港實際情況.

其實在2017年年底，通訊局已有文件顯示香港已有電訊商使用2100MHz做4G，但極少（約5％），如下：

而主要在地鐵沿線，估計是將原有的3G頻率調配出來。
相信有官方資料，應該可以結束今次的爭拗。

唔係爭拗
只係奇怪
奇怪(1)  CMHK A3 無BAND 1, 但又顯示係BAND1
奇怪(2)  測出來係BAND1, 但又話APP有BUG, 實際係BAND3
奇怪(3) 外國話香港無BAND1, 但肯定香港有BAND1

諸問 LTE band 1在香港的部署情況如何？有無 B3, B7咁普及？

Android 7 phones, showing erroneously Band 1
There have been recorded from users' feedback Android 7+ phones, e.g. cases of high-end devices, showing erroneously EARFCN = 0 which translates to Band 1. This is Manufacturer firmware issue, not ours. Since EARFCN = 0 (which translates to Band 1) is a valid number, we cannot filter it out. Please report this issue, to the device manufacturer.

Android 7+ phones, showing erroneous Band
There have been recorded from users' feedback Android 7+ phones, e.g. cases of high-end devices, showing non-existing Band for a carrier/operator. This is caused from erroneous EARFCN which translates to erroneous Band. Please check the EARFCN and the Band it gives, e.g. using this tool. This is android/firmware issue. Please report this issue, to the device manufacturer.

咁即係所有app都係錯啦, 原因係個firmware報錯俾個app

唔係所有，佢只係話“如果”你發現有錯，請告訴出產商問題。

好似師兄話齋，通常都root custom rom同埋畀錢app會比較準確啲

暫時check cell 既資料:
響無root機既情況下, gnettrack, NetMonster 同 Net Monitor Lite算係比較準確
可惜係一係睇唔到條LTE Band 開左幾多Mhz, 一係就睇唔到部機行緊幾多個CA

我張公司卡係數記既, 有陣時會收到LTE2100(B1) , 不過大部份時間都係首先收到LTE1800 (B3)或LTE2600 (B7), 然後會收到LTE2100 (B1)
我用gnettrack睇neighbor cell成日都見到EAFRCN399 (LTE2100), 少部分時間會見到 EARFCN28 (LTE2100),
