Is there a site survey service provided by Webe? My area only getting 1~2 bar 4G signal strength (or sometime 1~2 bars 3G signal strength) while using all other 4G providers in town. Signal dropped to 2G if I do not force the phone to use 3G only. I have tested it with Maxis, Digi, Umobile and Celcom in year 2017/2018. Result are the same.
