when I go out of town I have no phone service the phone just says sim card disabled. why is that before I got my new phone I had service everywhere I went but the old phone had no sim card the new one does. How do I fix this problem as I am often out of town.
It seems to be a coverage issue. If you take a look at the coverage map on koodomobile.com , you will see that there is a big diffrence between teh CDMA (phone without SIM) coverage and HSPA(phones with SIM) one.
