I am on android 4.4.2. Using Orbot + Orfox. I can connect the Tor network and browse webpages on Orfox when I am connected to a Wi-Fi. But whenever I turn-off wi-fi and try Mobile data, the pages on Orfox does not load. Here, How to make Tor work using mobile data?, they mention that mobile carriers may block access to Tor. And it is suggested that I should use bridges available. How can I do that? Checking "Use Bridges" option on android app does not resolve the issue (I haven't entered any IP address and port of bridges, since I do not know how to do it.)

  • First you need to fetch some bridges from bridges.torproject.org, pick obfs4 bridges – cacahuatl Dec 1 '16 at 19:20

    @canonizingironize I fetched some bridges from the address you provided. On the android app Orbot, I checked "use bridges". And entered the IP address and port of the bridge. The pages in Orfox still didn't load on Mobile data. I tried two different bridges, but it didn't resolve the issue. – sergeant_cuff Dec 2 '16 at 12:17
  • Did you also add the fingerprint, crt and iat-mode values provided in the bridge line? – cacahuatl Dec 2 '16 at 12:29
  • @canonizingironize I haven't added the fingerprint, crt, and iat-mode values. Now, I added them. I just copied and posted whatever the bridges.torproject.org provided me. Now it works. Now, I can connect through Tor network using Mobile data. Thank you. – sergeant_cuff Dec 4 '16 at 7:52

1- Get bridges:

Enter bridges.torproject.org on your mobile browser. On the page opened, click on "Get Bridges" option. Scroll down to the "Advanced Options" box, and select "obfs4" on "Do you need a Pluggable Transport?". I didn't meddle with the "Do you need IPv6 Addresses?" option. By default, I found the "Advanced Options" box already selected as "obfs4" and "Do you need IPv6 Addresses?" box unchecked. Then, click on get bridges. Do the captcha. Get the bridge IP's and ports and other information.

2- Apply bridge settings on Orbot:

On mobile, click Orbot app. Get to settings in the app. Scroll down to the "Bridges" header. Check "Use Bridges" option. Then go back to your mobile browser and copy all the line that bridges.torproject.org gives you as bridge information. Copy all the line. Then, head back to the Orbot app options, and click "Bridges" option. Paste the copied information in the pop-up. Click "OK".

3- Restart your mobile device:

Now, at first, I wasn't aware that I needed to restart my mobile device. So, the changes didn't have any effect. But, after restarting my mobile device, the changes seem to get applied. Now, I can connect to the internet through Tor network on mobile data.

  • You mean the whole line? – Pedram Jan 3 '18 at 11:55
