Can I put the koodo SIM card from my iPhone 4 into an HTC one S from telus
Up until recently, I had a LOCKED Telus prepaid LG P500. I dropped a Koodo SIM into it and it worked fine. Keep in mind you may have to register on the network to give it a kick in the pants to work. To do that, go to Wireless and Networks and then Mobile Networks, then Network Operators, then Search Networks. Select the Koodo, then it should register ok.
I did it in the past and it worked fine. I alo replaced a Telus SIM card with a Koodo SIM card (that was the beginning of my love story with Koodo) in a iPhone 3GS and it worked fine without changing APN or anything, it just worked. After all Telus and Koodo seem to enjoy an ongoing affair.
