It supports also supports AES-256 encryption. Telegram supports two kinds of Proxy protocols Socks5 and MTProto. MTProto supports HTTP, HTTPS, TCP, UDP, FTP network protocols. Tap on the slider on the right to turn on/off the proxy. To turn off the proxy, simply go to Settings > Data and Storage > Proxy settings > Use Proxy. Once you have setup Telegram to run via Proxy, you no longer need a VPN. Since telegram is by default blocked by your ISP, you want to access it via telegram web on a browser such as Opera with a VPN or you can simply use one of the VPN apps on your phone. All you have to do is select “MTProto” on the proxy type, enter the IP, Port and secret provided by one the choices listed.

You simply have to choose one and test it out. They keep an updated list of MTProto compatible proxies. I would opt for the factory reset old phone route though.Alternatively you can also checkout this channel.

Now authenticate the web client (on your PC's browser, so outside of the emulator).

Enter the verification code into Telegram.

Click next (and wait for 2 minutes for the text message to fail and Telegram to call you with an automated message).

Log into google (you will need an account to access the play store - but this can be a dummy account without a contact list).

Install emulator on PC (for example this one).

Assuming you don't connect that same emulator instance to an account that has a contact list, Telegram will never have the opportunity to access it. If you don't have one of these, there fortunately are emulators that allow you to run these from a PC. You can then either use Telegram on that phone, or use it to authenticate a web client on your PC. As with the second option you can use a dummy google account that has an empty contact list. Then you follow the regular install route and authenticate the web client.

The simplest option is to use a factory erased old phone that still supports Telegram (at least Android 4.1 or iOS 9.0 at the time of writing). You would still need a mobile platform though, which brings us back to that contact list.

Telegram will first attempt to send a text message, and if that fails after two minutes call with an automated message that contains an authentication code. The easiest is using a landline and voice authentication.

As with all the other mobile IM platforms authentication is required (and therefore a phone number), however there are ways around using a mobile number.
