A few weeks ago I bought an Android phone in India, popped in an Indian SIM card, plugged the phone into my laptop over USB, turned on USB Tethering, and connected to the internet immediately. It worked amazingly well out of the box!
This week, I'm back in Europe, and the roaming costs of an Indian SIM are rather high... So, I popped in a local SIM for the country I'm in, accepted and stored the Access Point from the Configuration message the operator sent me, and the phone itself connected to the internet fine. Apps worked, browsing worked, apparently all good.
Then, I plugged my phone into my computer with a USB cable, and turned on USB tethering. My computer connected, got an IP address, and.... Nothing. No actual internet connection to go with it!
This leads me to suspect that I'm missing some sort of setup step, but I can't find any Access Point / APN settings in tethering.
What do I need to do to diagnose this issue, and get tethering working again on the new sim?
