Unlimited prepaid 4G data sim for Taiwan – Chunghwa Telecom

Are you traveling to Taiwan sometime soon and would like a data sim for internet access? I can recommend Chunghwa Telecom’s offerings – this was the provider I ended up choosing during my travels. You can purchase a card with unlimited data on a time basis anywhere from 3 days to 30 days. You’ll get some voice credit included for making calls too, it’s a pretty good deal and certainly better than the options I’d come across nearby in Japan and Korea. For a 30 day SIM it’s ~1000NTD or roughly $45 AUD at the current moment. Another great inclusion is that Chunghwa operate WiFi hotspots in various locations so you can connect to these using your SIM card and unlike other providers you might have run into you don’t need to enter in login details each time you connect. The SIM card provides authentication so you can seamlessly jump between hotspots and 4G.

Current pricing directly through Chunghwa

You can purchase a SIM either directly through Chunghwa here.

Or via one of their resellers such as kkday here.

Both options offer airport pickup – simply choose the date you intend to arrive and then you can pickup the SIM at the airport. You will need to book your SIM ~3 or more days before the date you intend to pick it up. Personally I bought my SIM through kkday as at the time they allowed a shorter period of time between the booking and pickup date. Instructions on where to pickup the SIM are shown on the website and it was easy enough to find on the day. You will need two forms of ID – a passport and some other kind of photo ID such as a driver’s license.

The speeds were very good and there wasn’t any limiting or speed throttling that I noticed. I performed a large backup to Google Drive >200GB without any issues. This is a “true” unlimited service. I had no issues getting decent signal and speeds outside of Taipei either, the SIM worked great in Hualien for instance.

Fixing “Can’t connect to Group Policy Client service” on Windows 10

This is the method I’ve used to fix the “Can’t connect to Group Policy Client service” error on Windows 10. Symptoms – Log into Windows, no desktop icons, start bar not really working, and a little lock icon in the taskbar with that error message. A system restore will probably fix this problem, however it wasn’t an option for me as I’ve disabled the system restore feature.

In the start bar type cmd so that you see the command prompt shortcut.

Right click it and run as Administrator.

Type netsh and press enter.

Type winsock reset and press enter.

Reboot the PC.

This might not work on your first try, so try it twice just to be sure.

You should now be back at a working desktop after logging in.
Go to Start > Settings > System > Power and sleep > Additional power settings

Click on choose what the power buttons do over on the left.

Scroll down to shutdown settings.

Uncheck turn on fast startup
(If this is greyed out, up the top you need to first click “change settings that are currently unavailable”)

Save the changes.

Changing the NTP update interval on Windows 10 / 8 / 7

Open the registry editor and browse to:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet\Services \W32Time\TimeProviders\NtpClient

Select –

The default decimal value will be 604800 seconds – 7 days. Change this to whatever value you wish. So for example, setting this to 3600 will force the NTP service to perform an update every hour.


Roughly three months have passed since connecting to NBN FTTN via TPG. I’m on the “up to” 100/40mbit plan. At a guess I’m ~500meters from the node. At this point I haven’t had any issues with the horrible speeds/congestion that some users report. FTTN sucks compared to FTTH for a ton of reasons that I won’t go into. The bottom line so far is that I’m more or less able to saturate the speed that I’m syncing up at regardless of peak/offpeak.

Ahhh that's more like it!

2019 Update

Having all additional phone sockets unwired from the first phone socket/point of entry has resulted in a nice increase. The wiring was daisy chained from socket to socket, so it only had to be removed from the first socket/point of entry to be effectively disconnected. This removes a lot of additional noise from the line and thus an increase in sync rates and some differences in attenuation stats.
