OK Gang! Question 2, to solving my son's phones woes. As stated earlier, he purchased a Huawei Ascend P7. It has two slots for sim cards. A nano and a micro. One is marked: GSM/SD. The other is marked LTE/WCDMA. Which is the proper one to use? On a side note. I did enter the IMEI number into the Koodo Tool that checks if a phone is comparable with the Kood Network. I received the, "Should Work" message.
