Call failed anyone faced?

Question

iPhone

Hello,

I recently encountered such a thing - when an outgoing call gives out Call failed, and the call is reset - nothing happens.

I use iphone 4g 04.10.02, 4.3.3, gevey sim sandwich to work with networks - ej works fine, incoming calls, sms - sometimes come, similarly but more often with outgoing ones.

I read it on the net - they say this problem is not of hevea, but of networks and the device itself. Tell me who faced, how did you decide?

Answer 1

My friend faced this situation, but he has 3 iPhones. He said that he had read on the American forum that it was necessary to change the SIM card. He did just that and there were no problems.
Also, it is theoretically possible that the problems are with the contacts for the SIM card, and not with the SIM card itself.

Answer 2

I decided to look at the bourgeois forums myself. in many places they write the same algorithm:
Step1. disable 3G in settings
Step2. Enjoy a working phone. If it doesn't help, move on.
Step3. Go to Settings > General > Date and Time. There, uncheck the box next to "Set Automatically", and then manually set the city in which you are.
Step4. We reboot. If it doesn't help, move on.
Step5. Go to Settings > Phone > Show My Caller ID and set it to "Enabled"
Step6. Enjoy your work phone. If it doesn't help, move on.
Step7. Disable “Call Forwarding”, “Call Waiting”
Step8. With a high probability after these operations everything should work.
Try it.

Answer 3

Change the terminal temporarily to a known working one. If the problem persists, contact your operator. If you are persistent enough, they will transfer you to the second line of technical support, they will most likely help you there.

Answer 4
