My Iphone 6s had the SIM blocked a few weeks back because I thought I had lost the phone. I had the SIM unblocked by Virgin a few days later because I found the phone but it hasn't worked very well since.
I can't phone or text anybody - even when connected to my home wi-fi network. The signal looks good but the call fails seconds after hitting the call button.
Also, if away from home, I can only access 3G internet by rebooting the phone ..... which can't be right.
This has all happened since the blocking / unblocking of the SIM card.
Anybody have any ideas as I've given up waiting for an online agent to speak to !!!
Sorry to hear you are having problems with your device after reporting you had found the phone. From what I have read I imagine your SIM has been resumed but it sounds to me like there may still be a block on the handset.
I will take a look into this for you but in order to do so I will need some more information so keep an eye on the private message icon in the top right hand side.
