TPG Mobile – Fix on why can’t make or receive phone calls | Singapore

Using TPG mobile in Singapore? Wondering why you can’t either make a phone call or receive any? I got a fix for you.

TPG Mobile (or TPG Telecom) is one of the newest telco company here in Singapore, though actually they are not that new. TPG has been here since 2016 (check here). It’s an Australian-based telecommunication company, founded back in 1986 (here for more details).

Fix if you are unable to make or receive phone calls with TPG Singapore

Though TPG has stated it on its website and during mobile plan sign up, but I guess many of you just skip reading the notes the company is showing, and for those who even actually read the notes, some of you – including myself – still unable to get it right the first time.

Last year, I got my TPG Mobile FREE Unlimited Data SIM Card and has been a happy customer since then

TPG Singapore is using 4G VoLTE (Voice over LTE/4G) technology for making and receiving phone calls – not sure if TPG is the first telco to implement it here – but unlike the major 3 Singapore telco operators (Singtel, Starhub and M1), it doesn’t have the GSM mode, thus for anyone who use TPG mobile but using a non-compatible VoLTE smartphone, you won’t be able to make a regular phone call or receive any like how normally you do in a smartphone. But there’s a workaround for that.

To make and receive phone calls, you need to:

1) Install TPG 4G Voice app on the app store. Download link below.

2) Once the app installed, open it.

3) When prompted on accessing your contacts, give permission to access your contacts / phone books. This to allow you (later, when you need to make a phone call) to browse through your contacts.

4) When prompted on accessing your microphone, do give permission to access the phone microphone. This to allow you to talk when you make a phone call.

5) Finally when prompted on notification, do give permission to send you notification. Otherwise when someone is calling you, you won’t notice.

    have Redmi note 7 and it cannot get any mobile data. There is TPG 4G mobile network connection and the signal bar is full. I tried to do a reset of mobile network but still no internet connection. Does anyone knows how to fix this?

      Hi Gokulraj,

      Try setting the APN. Fill the APN Name as TPG, Username as TPG, that should enable Internet access to your phone.

    My Redmi XianoMi 4A can make calls, but cannot receive calls despite managing all the settings on the TPG app

    TPG auto cancel at end of trial? how to ensure they will not start charging me because they sent an auto cancel request and mention next bill will see charges. also what to do with the sim card? thank you

      Hi Jen,

      On my case, it was auto cancelled. I have 2 TPG numbers, there is 1 I keep, while another one I abandoned. On the abandoned one, I simply do nothing, but ensure you don’t have any credit card information tied to the number. In case you have, best is to send email asking for cancelation to their support.
      This is their support email address:
      FYI, they don’t have a number you can call, so email is the way to go.

    Hi, Jonathan,

    My TPG phone still can’t make/receive voice calls at all with my iPhone7 + after setting TPG for the APN. I tried many times to install TPG voice 4G, unfortunately the APP crashed during initialization, not sure what to do to fix the problem. My TPG works well in web browsing, SMS, etc.

      Hi David,

      Unfortunately when my iPhone is updated to iOS 14.2, the TPG Voice app is behaving similar like yours. In the past, during iOS 12/13, the app works well. In this case, we’ll have to wait for TPG to fix the app crashing issue. Sorry, can’t really help on this since I’m also facing the same issue like you and haven’t found a way to make it work.

    I recently bought a Redmi note 10 which is expected to be compatible with TPG.

    I changed the name and APN to TPG, my put the sim in first slot(The phone has dual slots) and switched off wifi and was able to make and receive whatsapp calls.

    I am not able to make or receive normal calls. Please help as i have been in touch with TPG support and no one there seems to be helpful. Extremely poor experience.

      Hi Pankaj,

      Currently I don’t have Redmi phone with me, so the steps I gave here may not be exactly the same like what you have on your Redmi.
      In short, there are 2 options:

      Option 1: Download the TPG 4G Voice App to make and receive phone call within the app. Here’s the download link:

      Option 2: If you want to make and receive phone call normally without app, you need to enable VoLTE.
      Go to Settings > Call Settings (Sim and Network)
      Tap Cellular networks > Enable Voice over LTE On/ Off.

      Hope that helps!

    While Redmi note 10 is compatible, i downloaded TPG 4G app and now able to make and receive normal calls……thanks

        The problem lies with the phone manufacturer disabled the VOLTE function. For Android phones, like the Redmi Note 11 with VOLTE specs, dial *#*#86583#*#*. The phone responds with a message to say “VOLTE carrier check was disabled”. Your phone Setting menu for SIM CARD and NETWORK will now have the VOLTE enable button.

        • July 31, 2023 at 12:49 pm

          This really helps. I am using Redmi Note 8 Pro and after I dial the code, it works like magic and the option “Use VoLTE” in the SIM card settings appeared and turn on by itself. As a result, I can make a phone call again! previously I can’t and couldn’t locate this “use VoLTE” option in the SIM card settings.
