Hi, Thank you to the people who wrote back. Here is my problem... I am not a very techy person. So I will apologize ahead of time for the "I don't know answers." When I tried to make a call I got the "no service message". I came on here and read some of the messages posted by other people with the same problem. It is then that I noticed the phone is saying "No SIM card." I know there is a SIM card in the phone. So I thought ok just take it out and put it back in again. WELL!!! I finally got the protective thingy off and then the back and I can not figure out how to get the back open to find the SIM card. Sorry again for all the words. My phone is ... a Motorola Moto G Does that sound right? Can you help me?
