Iphone 4 not sending texts or making calls?

I've resetted it to brand new, i've updated OS, I've checked the sim card in another phone and it works. Sms bar loads to 90% then says not delivered or failed to send message and when I try to make a call I get 3 beeps and get disconnected. Phone is NOT blacklisted (reported lost or stolen).

I bought this phone on amazon by the way.

Does anyone know how to solve this?

Take it to a phone shop.

  • Why isn't my iPhone 5 not receiving or sending texts to andriod phones? I just recently got an iPhone 5 (regular. Not 5s or 5c). I haven't updated to iOS7 yet but ever since I've gotten this phone it hasn't received or sent text messages to an android phone. I haven't tried calling yet so I'm not sure about that yet.
  • Verizon iPhone 4 not sending texts? I have an iPhone 4 though Verizon. Last week it was brought to my attention that my friend had texted me twice, however i never got them. So this got me thinking maybe i also hadnt been able to send messages. I looked online to check to see if a message i had sent that didn't get a response had been sent, and it did NOT show up on my verizon account. But my phone said it sent. What's going on? Is there anything i can do?
  • Texts messages not sending after iPhone update? I updated my phone two days ago. Last night my phone stopped sending & receiving texts. I was able to text one person, but everyone else I couldn't. I wasn't even getting a notification that my texts didn't send. What should I do? (I tried turning off iMessage & shutting off my phone, then turning it back on, but that didn't help).
  • My photos are not sending in group messages, but are sending in individual messages? I'm with Straight Talk Wireless. At first my pictures were sending in the group message but now they are not. I don't know what's wrong, all my settings are what they are suppose to be, and I'm currently on an iPhone 5s IOS 8.4.
