Please check if you encounter this problem only at a specific location and time or does it happen at all locations you are at. If it occurs only at a specific location, it might be due to high network traffic/congestion at that point of time.
If it occurs at all locations, please send us a screenshot of speed test, time, date and the location it was tested, to helpmobile@changirecommends.com.sg. We will investigate and get in touch with you shortly. I am having a lot of distortion on the call/unable to make call in the house. The reception quality may be reduced when calls are made or received within a confined environment in the building due to building structures and radio signals unable to penetrate the walls and windows.
