I want to know if its possible to trick this app "Diitalk" into either thinking I am in US or blocking it from knowing that my VPN is working cuz if I dont have a US based IP, it wont let me use the US based number.

Can this be done on the android device itself without having to use a VPN router or any other device?

  • Robert has explained it thoroughly. I have gotten similar experience before. While using LetsVPN I get restricted by most apps but then I switched to OpenVPN and boom, problem solved. I think you should also try a new VPN instead. – Mattjoe Dec 29 '20 at 14:03

VPN detection is usually done on server side.

Diitalk simply has to check your IP and compare it to a list of IP ranges by common VPN providers. If the IP is in the IP range of a known VPN provider it blocks you. This is known as blacklisting.

Therefore the highest change to bypass such a VPN check is to use a custom server and install your own VPN on it. If the server's IP is not in a range used frequently for VPN your VPN may stay undetected.

However the service you are trying to use may use a different VPN detection technique, like whitelisting. The IP ranges from US telecomunication providers are known and one can simply check if the IP is within a range or not. In such a case any VPN provider or self-installed VPN will fail.

  • The only chance I see is buying a SIM card from a US mobile network provider and then use it where ever you live. Using the mobile network roaming you should get an IP from the MNO home network (which is in the US as it is an US provider). Note that with an "US MNO" am not referring to an MNO of the same name in your country. You have to buy it directly from the US MNO! – Robert Jan 15 '19 at 18:37

  • Wouldnt it be odd if I purchase a US based SIM to get another virtual number – Curiois_Mind Jan 15 '19 at 18:45
  • Your question was about VPN, not about phone numbers... – Robert Jan 15 '19 at 18:47
