How to see mobile operator proxy settings My mobile internet suddenly has stopped working. Chrome complains Error 130 (net::ERR_PROXY_CONNECTION_FAILED). Google app store and other apps those load content from servers now work only when I connect through wifi.

I set in firefox about:config network.proxy.type from default value 5 (use system settings) to 0 (no proxy) and firefox has started working.

Proxy Settings app shows empty fields.

As I don't use any proxy I would like to see that system wide proxy setup which broke my mobile inet
For GSM devices, as far as I know, the proxy settings for your mobile data connection are defined in the Access Point Name (APN). Go to Settings &gt; Wireless and Networks &gt; More &gt; Mobile Networks &gt; Access Point Names &gt; [Your data APN] (your device's menu may differ slightly). Check the Proxy field - it's possible this got modified somehow. Might also be worth snooping around your carrier's website for the recommended APN settings and double-checking that everything is correct. Once finished, press [Menu] &gt; Save and give it a test.
