im not expert on opera, but that might be a cached version speed test. same goes to psiphon users using speedtest by ookla. yung mga nakikita nyong above 20mbps using H+ is not true.
but yours might be cached. but if opera is operating like puffin browser, then it is the browser's server speed. as some is using the so called "data saver". but your speed still remain the same as to what your local/isp's speed.
to ts, he seems to have a legit speed test for a 3g connection.
Accurate yan sir.. Mababang file load ang nagamit sa fast dot com wala ja namang iddl na file sample kasi para ma test ung dl speed mo.. Pero ok din naman sya.
