For us here in mainland China, VPN is mandatory. Without it, you cannot even have the basics.
In China providers and apps like Google, WhatsApp, YouTube, etc. are fully blocked.
Same goes for a large number of international websites.
For anyone who plans to come here for work or at least for a few months stay or more, they should install the VPN app before entering mainland China.
Once you get in and then try to download a VPN installation file, the block is already activated and you are left stranded.
Some VPN providers do have specific websites for those who live in China and do want to download the app installation file for the first time, but not everyone is aware of this.
In addition, few VPN provider apps do actually work effectively in China. And this also not everyone knows.
Before entering China I subscribed to Express VPN, only to arrive here and discover that it practically worked in one out of ten log-in attempts on average.
Then a colleague told me about ASTRILL VPN, and I am still with that.
I have also heard that LET'S VPN is also pretty ok, and this has been around for years.
Third point to note, again for China, is that once VPN is on then all the local Chinese apps either cease to function or function partially.
All mobile phones and computers available in the Chinese mainland market are by default blocked re Google, YouTube, etc.
Therefore if any visitors here wish to buy this type of gear then they should look to make a purchase in Hong Kong, etc. - global version of the phone or tablet you prefer of course.
Every time I try to upload pictures I have to turn VPN on for postimg.cc to work.
But then ATG logs me out once the VPN is activated...
