My unlocked verizon HTC M7 won't work with my Koodo SIM. I tried editing the APN settings (using this site http://aide.koodomobile.com/Portals/0/Phones/PDFFiles/Android.pdf
) but I cannot make calls. The koodo site says the IMEI should work. I do not care about having LTE or anything like that, just using for texting and calling. Is there anything else I can try?
