Complaint / review text:
Apple iPhone 4 and 4s never has service. Calls are always lost and Wi-Fi is always slow. I never receive texts at the time they are sent to me because my iPhone never has any service. Half the time, I try to make a phone call but it doesn't go through and when it does, I get about 5 seconds before the call is lost. The messages often change from text message to iMessage when texting other iPhone users. Whenever the iMessage change to text message, the message never gets delivered. Also, messages tend to fail to send often, probably due to lack of service.
