Voice calls


On Xiaomi phones, you can enable VoLTE using this command, just key in a the dial pad and dial *#*#86583#*#*

All three phones Huawei Nova 3, Xiaomi Mimax 2 and Samsung Galaxy Note 8 supports VoLTE.

Although VoLTE is enabled, tester is unable to make any voice calls. Making calls to the TPG numbers from other telco or fixed line failed too.

Update: TPG to TPG calls work but any outgoing or incoming calls from other telcos don’t. TPG to TPG voice calls work on Huawei Nova 3i and Xiaomi MiMax2., Redmi 5 plus. Tester can’t get it to work on the Samsung Galaxy Note 8 and Oppo R17Pro.

    Error occur when retrieving number.
    Please select a number.
    Not able to proceed from here..

      1. For the time being, if are interested, you can contact any friends that has applied 4 cards to lend one to you if they are willing.

    1. I think their server is overloaded. THey have temporarily closed applications.
      Perhaps you want to check http://www.tpgmobile.sg regularly and other FB pages for updates
      when they start accepting applications again.. It is really fastest fingers fast.

  5. Voice calls from other telcos to and from TPG doesn’t work. Only TPG <-> TPG works.
