Hi

I have a laptop with a built-in HSPA modem and SIM card slot. It is running Windows 10 Pro 64 bit (v. 1803).

When the SIM card is inserted, Windows is able to detect the Telkom Mobile network in the network menu that opens from the system tray. It shows "TelkomSA (HSDPA)" and "Disconnected".

Hitting the connect button just gives me an error.

I tried adding a few APN's in Settings -> Network and Internet -> Cellular, but all of them give me the same error as above.

I've tried the following options:
Name: internet APN: internet /// all other settings left blank
Name: TelkomSA APN: TelkomSA /// all other settings left blank
Name: TelkomInternet APN: TelkomInternet /// all other settings left blank

Can anyone guide me to do the correct settings? The laptop is a bit old, Dell Latitude E6430, but all indications to me are that this should work. The SIM card has been loaded with 2GB of data, and it works in a cellphone and B315 LTE router with no issues.

It might be worth noting that the user account logged in is not an Administrator, but I doubt this would have an effect.
 
Is there not a dial option in that menu? If so you should use *99#. Have you checked whether you have the manufacturer driver installed for this purpose? Everything else seems fine. I know the APN 'internet' as well as 'unrestricted' works. Could be a frequency issue with the built-in antenna.
 
Yes - drivers are installed. The modem shows up in device manager, and the fact that Windows is able to detect that the SIM card is inserted and shows the "TelkomSA" network with signal bars should be enough to indicate that the hardware is installed properly.

Regarding frequency, it's a prepaid SIM card, so should not be restricted. Roaming is also allowed. I know the Telkom Uncapped LTE SIM cards are restricted to working on Telkom towers, and only with LTE signal. Roaming not allowed. So I doubt that is the issue.

How do I do this *99# option?
 
I was asking about the drivers since Windows sometimes uses different / modified or outdated drivers.

I'm not sure of the dialing option using Windows as I don't have a built-in sim slot in mine - that is why I asked whether that option is available around there somewhere.

W.R.T Frequency, Telkom often uses 2300Mhz which was not a common mobile frequency a few years ago.

So I tried with an MTN SIM card, and it worked perfectly, without needing to even set an APN. My best guess, as you've pointed out, is incompatible frequencies between the modem and the Telkom network. The Telkom SIM card does connect occasionally, and works, but very slowly. I assume it is falling back to GPRS/Edge on a common frequency (1800mhz?) supported by both the network and the modem.

Thanks for the help.

Use Anydesk
 
Somewhere on the forum is a thread about a program called MDMA (Mobile Data Monitoring Something)

I used it to bypass the network lock on my Vodacom and MTN modems. The Vodacom one was an embedded mobile modem in my Dell Latitude D620
