I've been with sprint for about 4 years. I got my iPhone 6 a month ago. I've been having issues with i-messages, safari and calls. Unless on wifi, i cannot send i-messages. It still goes through as text messages though. However, I cannot receive text messages at all unless on wifi. Unless on wifi, I cannot open safari and cannot receive voicemails. I got in touch with Apple and they did their diagnostics and I was told the issue is with Sprint's signal. I got in touch with Sprint and I was told it's the phone's (hardware) fault. I went to Apple store and they replaced my phone but I am still having the same issues so it's definitely Sprint's connectivity. I called Sprint and they did another set of troubleshooting and they're blaming Apple again.
There's no specific location. It's everywhere. Im mostly in Middlesex county in NJ. Same issues
I've been having almost the same issue but I can still use the Internet I can't talk on the phone or use my text messages I talk to sprint and apple nobody could tell me the problem and it's been a whole month since I used my phone and I have been back and forth through sprint and with brand new phones nothing worked
