I bought an HTC Desire 320 when my s4 crapped out, I put in my Koodo sim card and checked the APN settings and anything else I could think of and the data connection does not work. I have reseated the SIM card and rebooted the phone a dozen times and nothing. Then I switched the SIM cards with my other Koodo phone and magically I had a data connection on both phones. But when I swapped the SIM cards back there is still no data connection on the HTC. Is it possible that the SIM card is not compatible with that phone? The data connection is turned on but in About phone/ Settings/ status it shows disconnected.
